BBC Top Gear - To Argentina - DO NOT APOLOGISE!

If they apologise I'll have a fit... I will seriously throw my rattle out my pram... Fuck Argentina, they conducted an illegal war against a British protected territory, whom has repeatedly stated its people wish to remain British... I am so suck of Argentina and this topic...

Just go on YouTube find a documentary about the Falklands war and read the Argentine comments...

One guy was trying to claim the Brooklyn class CRUISER the General Belgrano was a transport ship... Are you fucking retarded?... It was a CRUISER when it was laid down in the '30's and it was still a cruiser when we sunk the bastard!

It just seems whenever there's something to distract the Argentine people about they wheel out the Falklands... And the people follow like kittens being shown a ball of yarn.... Wake up people your politicians are hiding shit from you.

Like the Military Junta of 82 was hiding it was disappearing thousands of people... Remember them, not some trifling war they used to try and swing your opinion, and grow up you lost, grow a set of balls over it!


WarThunder - Gaijin's Russian Bias Shows Doesn't It.

Last night I went for a few flights in various BF109's in WarThunder... It was an utter and total disaster, I didn't make a single air kill, and twice ended up getting bounced whilst in the middle of my dive on a target and having to try and flee.  And only once did my attempt to flee and calling for help get a return from my team mates... So my thanks to those chaps that time, you kicked arse...

However, after a couple of hours I had my BF109E-3, BF109F-1 & 2, BF109F-4 and BF109F-4/trop all in repairs... My frustration was palpable.

I reviewed my replays, I thought about what I was doing wrong, and I thought about my opponents... Some of them were just excellent pilots and out flew me, I accept that, however, I looking at the roster of opponents who had shot me down... La-5... La-5.... Hmmm... La-5..... I-185... There were a lot of higher battle rating (BR) opponents than my measily E-3 or F-2 (the two planes I flew repeatedly)...

Now I'm no fool, my aircraft handling though not perfect is okay and in Simulated Battle you expect an amount of luck, but my luck was running so bad.  I switched to Realistic Battle, maybe I could identify what I was doing wrong by seeing the target tags coming towards me...

I could not see any tags... I don't know if this is a feature now, or something about skills, or just a bug... But I had to close to within 1km of a target dot before I got to see its label text... and when friendlies were tangling with enemy planes I saw the blue of the friendly from miles, but never saw the enemy... Tracers and flame and death, I saw plenty of, but actual aircraft/player legend text, not a jot of it...

So at one point I'm in the F-4, and I'm 800 meters above a pair of La-5's... I know I'm going to die, so I invert, pull through a half loop, and when out of the loop I'm the right way up going to opposite direction at about 550km/h... And I accelerate away, I'm going maybe 580km/h, and I reckon I'm around 10km away from where I saw the targets, I'm low on ammo anyway, and 7 minutes of fuel, so I report heading to base.

I check my shoulder, just as a stream of red tracer goes past... both La-5's are right there... they've climbed 750ish meters and caught up over 10km from behind a plane going away from them at over 550km/h... I dive away from them and am going 715km/h, opening the distance between us... But their fire is hell accurate, I can see the separation on the mini-map its over 800 meters between us, but they're still shooting...

These are La-5's... with twin 20mm cannon, their cannon should be dry>?!>?! What the hell... I lead them off and over the airfield, they break off only when the AA has holed one... but as I break into a rising climb turning my now 600km/h speed into about 900 meters of altitude and levelling off to assess my situation, the other LA-5 does what can only be described as a UFO move, it rolls and almost flat spins around and comes back at me, acceleration was incredible, the aircraft was level with me, having used his speed to climb... and he's flying straight and level.... over 8km... be cross the airfield and forced me into a split-S to avoid his head on in what felt like 10 seconds... I literally had no come-back.

When we read historical accounts of the performance of the La-5 it does not stand up to the scrutiny of its performance in game, I get that Gaijin have their own ideals of history, they say as much in one of their news posts:

"the British have their own history and their own view on the Second World War and we, the descendants of our Soviet heroes had our own war and own memories of it" - WarThunder Blog.

You don't have memories young sir, you are not over 80 years old and were of an age to have served, your parents at a push, or your grandparents certainly may have, but you do not have memories.  What you have are recollections, those rosey tinted, glossy postcard photograph ideas of what it was like.  And I can only really stress that in my opinion the balance of plane performance, especially Russian plane performance, is rather more rosey than it should be according to the history at hand.

"the La-5FN excelled at altitudes below 3,000 m (9,843 ft) but suffered from short range and flight time of only 40 minutes at cruise engine power. All of the engine controls (throttle, mixture, propeller pitch, radiator and cowl flaps, and supercharger gearbox) had separate levers which served to distract the pilot during combat to make constant adjustments or risk suboptimal performance. For example, rapid acceleration required moving no less than six levers. In contrast, contemporary German aircraft, especially the BMW 801 radial-engined variants of the Focke-Wulf Fw 190 front line fighter, had largely automatic engine controls with the pilot operating a single lever and electromechanical devices, like the Kommandogerät pioneering engine computer on the radial-engined Fw 190s, making the appropriate adjustments. Due to airflow limitations, the engine boost system (Forsazh) could not be used above 2,000 m (6,562 ft). Stability in all axes was generally good. The authority of the ailerons was deemed exceptional but the rudder was insufficiently powerful at lower speeds. At speeds in excess of 600 km/h (370 mph), the forces on control surfaces became excessive. Horizontal turn time at 1,000 m (3,281 ft) and maximum engine power was 25 seconds." - 

Or perhaps
"In comparison with the Bf 109 the La-5FN possessed a slightly higher roll rate, however the Bf-109 was slightly faster and had the advantages of a smaller turn radius and higher rate of climb." - Hans-Werner Lerche (ISBN 0531037118)

Even ignoring the performance issues, why was my BF109F4 being pitted against La-5's?... The F series of 109 was ubiquitous yes, but in 1942 when the F4 was really at its height the La-5 was still under development:

"from the first tests, which began toward the end of March 1942, it became clear that the new variant was a marked improvement over the basic model" - about the LA-5 from www.century-of-flight.net.

The timeline does not work out, the La-5 should not have been present to shoot me down perhaps?... But its UFO like performance is clearly not warranted from the history.

I know already what Gaijin's response would be, if they dained to give one, and that would be that this is a BETA, and that things can change, but I believe for too long and too many comparisons; which I have been through; the Russians get the better of it over the Americans, the Americans get the better of over the Japanese and the Germans generally struggle to compete save when we get to the very highest tiers.

The BF109F series under-perform, the accepted best aerobatically able 109's and they're pitted against floating Russian crates which historically were not overly available*, the BF109G series are often forced to fight off of their comfort zone, i.e. the BF109G-6 designed to intercept bombers is pushed into dogfights with other fighters, where its climb/weight disadvantage soon tell...

To then rub salt into already open wounds I flew out in a Russian plane, in simulated mode, for the first time ever, took the Yak-7 which was completely stock out for a fly out... Immediately entered a low-level dogfight and in both the horizontal and vertical could out turn and out perform German BF109F1's and an FW190A-1... And got two kills!.... I gave up playing for the night right there, disgusted how easy the kills were, when ammunition, aiming and the general low-tech of the Yak-7, a trainer pushed back into front-line service, bested some of the finest fighter aircraft the Luftwaffe fielded.



* Losses of La-5's in 1942 dropped dramatically, this wasn't because the La-5's were doing well, but that so few La-5 were produced that there were none-left for the jagdflieger to shoot down, only in 1943 as production ramped back up did losses increase in relation ship to the number of available aircraft.  This is the kind of history ignored by Gaijin and their apparent blanket rosey tinted view of history.

Gloriously Impatient

Good news, good news... Most all the decorating is done!

Yes, in the last three weeks, we've gutted the bathroom, laid new floors, painted lots and lots of gloss onto surfaces, repainted the kitchen, sanded and re-varnished hard wood floors and generally made the house a better place to be.

The reason being, we're moving back to the old house at Brinsley, we're not sure on the old rental market or valuations so that's all going on, but our old tenant is leaving so we're having a new hearing system put in up there and going into that.

The major difference will of course be the lack of storage, the Brinsley house has not got a Utility room, nor a cloak room, nor a loft space, nor an 18 foot out building... So where will we be putting our crap?.... Who knows.

The Virgin Connection is being switched over on the 16th November, so that gives you a heads up when I'll do full dark before hand.

The one worry we have at present is, I headed up to the Brinsley house to give the tenant her finalising letter and get a schedule for her moving, so I could get the plumbers in on the case with the heating, and instead of the tenant another girl hung herself out the window... "What you want?"...

"I want to come in"

"No F**king likely perv"

"No, you miss understand, I'm the landlord, the owner, I have an appointment to measure up for my new heating system, where's XXX"....

"Oh I live here now"....

Oh no you don't lassie, and so she's been oiked out, turned out the tenant could not fully afford it after her last relationship broke down and she got this girl in from her work to share the bills... This girl is the dirtiest schmuck I've ever seen... Uses feminine hygiene products thrown in corners of her bedroom, the carpet stank, she had dirty clothes and rubbish everywhere....

And when I mentioned this needed cleaning up she said "You starting?"... To whit I could only look at the used tampon and say "No, but it looks like you have".

Dirty, disgusting pig... 

The ex-tenant has to therefore pay to clean that carpet professionally, and clean the whole house...

The other thing I noted was that nearly every light bulb in the place was popped... These were new light fittings put in before they took possession, they're less than 11 months old, how did they pop them?.. And how, if "they've been gone ages" did they see, because the landing and stairs run down the middle of the house and are very dark....

Anyway, the lots of decorating will continue I think Friday is a key day, with the estate agents coming.. Then Sunday we have the bathroom ceiling being plastered, so when he's done I'll paint the bathroom wall and lay a new bit of lino... and finally when that ceiling is dry I can paint it.... I don't envisage many WarThunder or Code hours to myself in that time.

However, what I do have in the works is my own personal, and hopefully comprehensive, series (4 parts) covering my fascination with the BF109 fighter, I'm posting this 4 part history from my own sources soon, and also developing a series of "In Game" videos for the type.

I already have one large (45 minute) video ready for upload, but that was from pre-v1.43, so I'm trying to get sometime flying the type post patch.  And when I say "Flying", we're talking exclusively Simulator Battle level detail.

AO.COM... Yes, a review of a website for you all, this lot have a real mixed experience for you, my experience went from being quite happy with my purchase to utterly and totally dismayed by them, so much so that I ended up having to call them and threaten them with a cease and desist order.


Lets explain, Monday our tumble drier died, Tuesday the house was getting over run with washing drying, so Wednesday the wife asked me to sort a new drier... We're strapped for cash, so cheap cheap, was the order of the day, I checked Coop Electrical, and they had a drier, but you had to pay delivery and it'd take a few days, and we have the estate agent coming... yadda yadda yadda...

So I looked elsewhere, and remembered a TV advert for "AO, Lets go"... bringing their site up, same drier, same price, free next day delivery... bargain?>!?!... I ordered, and at the end of my ordering process it asked me to update whether I wanted to be contacted with offers, and I declined.

However, I had set all the contact details, the email, the mobile number to my wife...

Next thing I know she calls me, "Who are these AO that keep calling?"... Oh, I thought maybe they were trying to arrange the delivery...

No! They were telemarketing, trying to sell the wife cover for £2 a month or week or something for the drier, the drier which a) had not even arrived yet and b) she knew nothing about and c) which I had declined contact on.

So I sent them a nice e-mail asking them to stop... because by then the office was closed, but they kept on calling, 16 calls later and the guy was pestering my wife, she said he was pleasent enough, but when she said "I am sorry, I do not do anything with the bank, I can not set up, and do not want to set up any payments for protection" the guy said... "Go find a bank statement, the husband won't want to miss this offer, get the bank statement and read me the numbers, I'll set it all up my end"!!!

THE FUCKING CHEEK OF THAT!

I'm pretty sure that's illegal, and the pressure it was putting on my wife, you must understand she suffers anxiety, social anxiety, that I've even got her to answer the phone is a big thing, but to have this arsehole calling and hassling her was totally unacceptable.

So, come Thursday lunch the calls not abating I asked the wife to read me the number and I called them, and I got this gal, now she was not the one calling, and I said it's not her fault personnally, but it is the fault of the company, she took my info and appologised.

Meanwhile the drier was delivered and my wife asked the driver about the calls, "Oh christ" he says "the number of complaints they have".

Pressure sales, pushing and pestering, pissed me off... And it seems they're more than aware of it, bunch of wankers.

I'll never be buying from them again, and I'm pretty sure if you read this you should take my sage advice and avoid them too.  Coop Electrical, just as good, zero hassle, and we've had fridges and driers and washers from them before.

We will never be buying from AO again!

Also of interest, I used the wifes e-mail, yet just after browsing their site I was receiving junk mail in my inbox... "You've left something in your basket"... HOW THE HELL DID THAT SITE GET MY E-MAIL?... Clearly through accessing data on my machine, cookies most likely, but... That's against EU law, they've just passed a law saying that sites using cookies must inform you they're doing so... The AO site did no such thing, I got spammed, and when I hit unsubscribe you get someone dressed in a badger on the site giving you gip, it's all just not very funny after the pertubation of bullshit they've put us through, over buying one drier, once...

NEVER AGAIN, AVOID THEM!

Aircraft History - BF109

Lets talk about the BF109, quite possibly my favourite aircraft of world war 2...

"Yes, I am British with all those spitfires to pick from..."

Please Note, I will be using actual Historical images taken from the Historical period throughout which the 109 was in use by the Luftwaffe.  Therefore there will be images of the aircraft showing their then national insignia, including the swastika.  This is purely for historical purposes and is not intended to cause any distress or offence.  If you have any problems with such images, please do not read beyond this upper visible area.

Also please note, this work is my own words, it has been researched for the purpose of the narrative, however this text is not intended to be a source of reference or true history.  I am not a historian, just an enthusiast.


PROLOGUE
The 109's design of most all other nation's fighter designs and was the first fighter of all the "classic" airframes we know and love to see action in a European war, indeed by the time it met with comparative competition from other modern fighters over France in late 1939 and 1940 it was a well honed machine, already having seen four years of development and two years of real combat exposure.

In the skies over Spain when the 109 first flew into combat it was described as "ultra modern", not surprising in comparison to the aircraft attempting to oppose them.  This aura followed the 109 until the end of the Battle of Britain, the first stern challenge the type encountered.

Prior to meeting the RAF in numbers in 1940, the 109 had met limited British and the best French fighters, however with the best French offering, the D.520 was still in development and only available in very limited numbers, meaning that the 109 remained supreme compared to the Bloch and Moraine fighters, as well as the Hurricanes flung against it.

However, we're rushing too far a head, let's go back in 1935 with the technical specification issued by the covert legislative bureaux, trying to rebuild the military air power in Germany.

So it was the specification arrived at Bayerische Flugzeugwerk (BFW), whom turned them over to their in house designer Willy Messerschmitt, working with Rober Lusser they produced a design for a monocoque, monoplane, single engine fighter.

The next design code available for the company was design number 109, so a legend was born as the design was dubbed the BF109.

The basis of this design stood the test of time, both pre-war and during the trials of fire which followed it.  Only the Spitfire saw more versions, and more varied use, when comparing the two as stable mates.  However, the BF109's design was slightly older, and it does still retain the title of the "Worlds Most Produced Fighter".

Our discussion of the 109 lineage will span four distinct eras, the pre-war, early war, mid-war and then late-war.  Lets get started...

PREWAR
As we've already mentioned 1935 saw a specification sent to manufacturers for a new fighter to re-equip the fighter arm of the still covert Luftwaffe. 

This new fighter arm was called the Jagdwaffe, the pilots the Jagdflieger.  But before they could get their hands on the 109, much development and evolution of the type had to take place.

BF109V1 - On static engine run test, note there is no-one present in the cockpit, also that the air intake is rounded, unlike in other prototypes, this was of course the Rolls Royce Kestrel Engine at work.

BFW produced ten prototypes from the design, these received the official designation BF109V1 through V10 and went into head-to-head testing and comparison with other designs from Arado and Heinkel.


BF109V4 in Flight, 1936, note the mouth like air-intake below the cowling.

However, the major stumbling block for the Germany of 1935 & '36 was the lack of advanced aero engine designs.  Indeed, the initial engine used in the first prototype was a British Rolls-Royce Kestrel MkVI, which it is reported (but I can't confirm) was attained in exchange for a complete Heinkel He 70 airliner.

The first indigenous German engine fitted to the 109 V-2 prototype was a Junkers Jumo 210 engine, producing just 600 horse power. The Jumo series remained the power plant of the 109 through both the first "A" model production runs and the second "B" models, which we will talk about soon.

Junkers Jumo 210D engine, rated at 600 horse power.

Through the good judgement of the original Technical Specification it was dictated that any airframe produced for the fighter projects (from Heinkel, Arado and BFW) should each be able to mount a series of different engines, with a common engine mounting arrangement.

So, whilst the fighters were being developed, in tandem Daimler Benz were working on their new 12v in line aspirated engine series, starting with the DB600.

Whilst the ten prototype aircraft were well into the planned testing and evaluation programmes and doing well, the 109 won out against the other designs and were accepted as the winner in 1936.  This moved the airframe from prototype into the first production model receiving the designation of BF109A.

The "A" or Anton model was built in small numbers whilst BFW ramped up jigging and experience with production, however in early 1937 aircraft began to arrive with squadrons, shedding the development aura of the aircraft the "A" models quickly evolved and by Spring 1938 "B" for Bertha models began production.

The "B" series mark the first of our real pre-war era fighters, they saw action over Spain, replacing the ever aging Heinkel He 51 biplanes in service with the German Luftwaffe under it's auspices as the "Condor Legion".

The BF109B was powered by either a Junkers Jumo 210D or E engine, and was armed with three 7.92mm MG 17 machine guns.  Not as potent as later models, however they were far in advance of the rag tag band of fighters the Spanish Republican forces could muster, and they did out class the Soviet supplied I-16 fighters in everything save turn rate.

Experience in Spain also acted as a catalyst for the development of the 109, and the pilots using it, moulding the tactics which the Jagdflieger would employ to dominate the skies of Europe in just two short years.

BF109B2 in 1938.

Whilst the "B" models were flying over Spain, at home in Germany from November 1937 a new "C", for "Clara", series was coming to fruition, one example of the "C" series was taken stripped and specially fitted with an aerodynamic skin, further fitted with a special Daimler Benz engine sporting 1,650 Horse Power, the aircraft was re-designated the BF109R ("R" for record breaking) and immediately set a new air speed record of 379 miles per hour.

Later re-designated the Me209, to distinguish it from separate work of "Bayerische Flugzeugwerk" (BF) and work of Willy Messerschmitt at his independent factory.

Three more "Record" setters were built, these 109's are the only aircraft of the type it is correct to refer to as ME109's, all other 109's are "BF109" for "Bayerische Flugzeugwerk".

The "C" series which spawned this special edition, was the first to do away with the until then distinctive mouth scoop air intake, changing to a slit under the cowling, such mouth scoops could be found on other fighters, such as the P40, Typhoon, MS406 and even the Stuka.  However, they are nearly always more about the engine than the airframe itself.

The biggest problems between the "V", "A", "B" and now "C" series to date had been the lack of decent armament, some models only carried two or three 7.92mm machine guns, which drum feeds which were liable to jamming during high-G aerobatic actions.

In parallel however several new airborne machine guns and cannon were being developed, ranging in calibre and using ammunition from the German Rifle Standard 7.92mm, to 20mm up to 30mm diameter.

As these new weapons came into use, so the 109 changed to trial and even in corporate them for use.

As the factory matured, so a push began, to prepare the design for better, more efficient, manufacture.  The first model to benefit from this effort was the "D" for "Dora" series, which took steps to unify the armament as two guns mounted above the engine in the cowling and two guns mounted one per wing.

However, the first step towards unifying production of the "D" series, was made when it received the then new Daimler Benz DB600A engine.  Improvements were also made to the radio, air filter, oil/cooler interchange and radiator, this allowed the aircraft to leap into the air as never before.

BF109B1 - Note the three aerial wires.

BF109C2 - Still showing the mouth like air intake.

BF109E3 - Showing the smoother new air intake of later engine & cowlings.

EARLY WAR
With it's partnering with the DB600 providing more power than ever before, and importantly being direct fuel injected; rather than using gravity fed carbourettas; the "D" series see's the 109 find it's feet, solving problems other types (notably the Spitfire) would not come to grips with for another two years. 

These improvements really transition us from an aircraft of the pre-war era to the early-war experiences, indeed "D" models were in the front line squadrons as Germany retook the Rheinland, annexed Austria and invaded Czechoslovakia's Sudaten land.

"D" series aircraft were also hand as German forces crossed into Poland in 1939, however by that time the "D" series were being recalled and the new "E" (for "Emil") series were appearing, and the "E" series lead the Jagdflieger all the way to the Western border of mainland Europe in 1940.

The "E" series differed only slightly from the "D", in that they flew with the ever improved engines from Daimler Benz, the DB601 providing around 1000 horse power.

The E1 also had the first of a new model machine gun, the 7.92mm MG/FF machine gun replacing the MG17's, again still two were synchronised firing through the arc of the prop from positions on top of the engine cowling and one in each wing firing.

The E1 also provided the 109 with the first production version able to carry out bombing, with the BF109E1-B able to carry a 250kg bomb under the central fuselage between the undercarriage.

This same fitting for bombing was also modified to carry a drop tank in the E-7 version.

Almost as soon as the E1 variant was coming into production, kits were issued to squadrons in order to upgrade the wing mounted machine guns from 7.92mm MG/FF to 20mm MG/FF cannon.  This kit required ground crew to remove the wing mounted guns, cut a larger hole in the underside of the wing panel and fit the new gun.  A bulbous oval plate being supplied as part of the kit to cover the new gun and give the wing a smoother aerodynamic foil shape again.  This became the first cannon armed 109, and proved a very popular gun arrangement for the next year or so.

Many of these upgrade kits were kept around, indeed there are stories of Adolf Galland having a 20mm MG/FF cannon kit retro fitted to his later BF109F models in 1941, as he preferred that armament.

It is with this armament of two MG/FF and two Cannon which gives us what is perhaps the definitive version from the "E" series, the factory cannon armed BF109-E4.  The E4 improved on the E3 cannons, and almost all E3's were converted to E4's with yet another field conversion kit being issued rather than recalling all the airframes.

After the Polish campaign the remaining "C" and "D" series units were fully re-equipped with the "E".  And the E3 and E4 were the primary fighter type during the phoney war and the later Battle of France from 1939 to early 1940.

A restored French Morane-Saulnier MS.406

The Armée de l'Air primarily flew native Morane-Saulnier MS406's, imported P36's under the name 'Hawk 75' and native Bloch MB.150 aircraft, and represented the first modern Western Airforce the 109 faced off with, however the French were swiftly overrun by the 109's.  With only their Dewoitine D.250 of comparable performance to the 109.

The 109 also first met British fighters during the Battle of France, in the form of Hawker Hurricane Mk I's and Gloster Gladiator biplanes, which equipped the British Expeditionary Force squadrons.  The latter suffered to the 109's, however the Hurricane was found to be able to out turn the 109, and held it's own on the defensive, whilst not quite being on even terms to face the 109 head-to-head.

It was direct fuel injection which gave the 109 its deadly lead, as it could pull negative G, whilst with gravity fed carburettor's the Rolls Royce Merlins in the Hurricane, and later Spitfire, could not.  109 pilots soon learned to dive away from attacking British planes, and not to enter turn fights with the British.  Anecdotally there are tales of British pilots even reporting the exhaust spurt of black smoke of an accelerating 109, with its dive towards the ground, as a downed aircraft.  Adding to the chaos of battle with vast over claiming by RAF pilots.

However, by early summer the Germans had free reign over the French coast and 109's were stretching their legs over the channel.  The Battle of Britain was about to begin.

The "E" series carried the Luftwaffe into the Battle of Britain, and the series ran to the largest production-run quantity to that date, with just over 1,250 airframes completed.

During the Battle of Britain, with the extended operational ranges required over the English Channel, some say the 109 design showed it's first flaw, as the range was not sufficient to operate over England for more than 30 minutes, and no 109's really ever flew from Norway to attack Scotland.

Over southern England with their 30 minutes from bases on the French mainland 109's never flew further in-land than London, and even then only stayed for 10 minutes, all excluding any fuel time expended on combat, which drastically reduced range.  Needless to say many 109 pilots learned how to glide the type back over the channel, and belly landings in French fields, as well as ditching, were not uncommon.

This lack of endurance for the type proved problematic for all models, however the high powered (1,200 horse power DB601N engine) BF109E-7's did carry the aforementioned external fuel tank flying further, but they were kept almost exclusively for  photo reconnaissance (as a side note the E7's also flew from Norway, but I have not found any information about their appearing over Scotland).

The fuel problem however, really was not a fault of the design, but rather the German High Command asking too much of their thoroughbred fighter. The original requirement issued in 1935 "Rustungsflugzeug III" stated "short range interceptor" as one of the primary requirements.

With the development of the Blitzkreig tactics of the late 1930's the 109's position in the pantheon of military operations was therefore to provide close air support and cover for advancing ground forces, being anywhere between 2 and 10 miles behind the front lines, its range therefore was perfectly suited to the action it was to take-part in.  The design was never intended to fight a war against a distant foreign nation like Britain separated by a minimum of 26 miles before combat was even engaged, the 109 was meant to be used up close and personal, as an in your face statement of intent, not as the long arm of air superiority over a foreign nation.

I therefore can not pick fault with the 109's range, especially when we think about the two main opponent aircraft, the Spitfire and Hurricane, both using the same Rolls Royce Merlin, which; as we've already mentioned; used gravity fed carburettor's.  And had around an hours flying time from full fuel load.  Unfortunately the British were defending, so could land for fuel easily.

BF109G2 - Later in development than the E7, 
clearly showing external fuel tanks of the same style.

Back to the development of the 109 however, and we find the late BF109E-7  also introduced a change to the armament plan-form, one which influenced the next generation of 109's... For speed and altitude through weight reduction, the E7 lost one of its wing mounted 20mm cannon, balancing the airframe by moving the remaining 20mm into the nose.

Firing through the propeller spinner, this new arrangement of two machine guns and a cannon in the nose became the armament standard for the next series of 109 now on the drawing board.  It also marks our departure from the early war into the mid-war period.


MIDWAR
We'll start considering the mid-war era with the changes to the armament on the 109.  This concentration of all the fire power in the nose aided aiming, but it received mixed feedback from pilots, some preferred the new layout, others disliked it intensely, indeed we've already mentioned Adolf Galland ordering an older 20mm wing conversion kit be fitted to his BF109F aircraft, that aircraft was an F2 model, and he flew it in France until 1942 where upon he was moved to the Jagdflieger High Command and history loses track of the aircraft.

Concentrating fire power in the nose simplified the wings, and allowed two separate design teams to work on evolving the aircraft simultaneously.  One team worked on the wings, redesigning them for letter effect, whilst a second team worked on the engine cowling, cockpit and fuselage.

The "F" series came out of design and into production sporting an obvious change to the wings, gone were the cut off wing ends of the original design and in came a new rounded wing tip.

The wings were not the only change, the whole airframe went though a full perturbation of incremental design with regards aerodynamic resistance, which spawned straight from the advanced wind tunnel programmes the Germans were running.

Some sources state the "F" series as being designed in response to the Spitfive V appearing and out classing the "E4".  However, German sources show the "F" series was already being developed, and so it's aerodynamic changes coincided well with the need to counter the now fast evolving Spitfire.

As well as the external refinements, internally the cockpit layout the "F" series was simplified and improved, and once in squadron service some started to call the "F" series the best, and later the peak, of 109 design evolution.  It had evolved into a powerful agile fighter and was as yet unfettered with the pressure of defending (interceptor role) the Reich, indeed, the "F" designed remained the basic airframe until the end of the war in Europe and stayed in service with the Spanish until the 1960's.


BF109E - under going engine & gun maintenance.

The German fighter force which swept across the Soviet border in the Summer of 1941, was predominantly made up of "F" series 109's, and they quickly swept the Soviet air force from the skies.  One must remember the Soviet air force was much under manned, with equipment still of 1930's vintage, and with little or no early warning systems.  And a high command paralysed in disbelief at the German aggression.

That said, these new 109 designs did also enter squadron service on the Atlantic wall pitting themselves against the Spitfire V until the Fw190 started to equip the Western Wall.  So the early "F" model should never be dismissed, especially not as some sources quote "the 109 used to shoot Russian fish in a barrel".

The first "F" model, the F1 was equipped with the same 20mm MG/FF cannon firing through the propeller hub.  Almost as soon as the production started the cannon was swapped to a 15mm MG151 gun in the F2 model, though a smaller round this 15mm shell had a higher muzzle velocity and improved ammunition technology vastly improved the convergence of both the machine gun and cannon fire from the nose, making the plane deadlier than ever.

BF109F2 - Presumably somewhere in Russia 1942, the Pilot is one Peter Gerth.

In the East, against such aircraft as the Polikarpov I-15, I-16 the fire power of the 15mm cannon proved more than sufficient, even when pitted against Lagg or Mig fighters the 109's still held the upper hand using radio and years of combined experience, where the Soviets still for the most used hand signals and flew straight and level to and from patrols, totally undermining the more potent fighters they could muster.

despite dogged determined bravery by their pilots.

The F2 only changed some six months after the Eastern war had began, in late 1941, as more modern metal skinned Soviet aircraft did began to appear and Soviet pilots improved, a new "F4" model of 109 appeared sporting an up gunned 20mm MG 151 in the nose.

The other innovations seen at this time was the addition of field modification kits to add under wing 20mm MG FF/M cannon under each wing.  These gun pods proved to be a feature on many models of 109 right up until the end of the war, aiding the aircraft to stay competitive as a high-altitude interceptor against the Allied Daylight Bombing Campaign against the Reich.  We'll discuss the gun pods as they evolve with the airframe.

Over all the "F" series saw the most diverse service with Luftwaffe squadrons, ranging the skies at the height of the German continental domination, across the deserts in North Africa, north into Scandinavia and out into the vast unconquerable East.

However, even with these successes the "F" series was by 1942 already under scrutiny and in the pipe line was the "G" for "Gustav" series.

Replacing the most diversely employed series the "G" became the most numerous of all the production runs, however the G was always heavier than the F, and therefore many pilots found they lost manoeuvrability and some critics say the 109 turned away from being a pure fighter into more an interceptor, gaining altitude and diving on an enemy was always the preferred method of attack, even the British had the saying "Beware The Hun in the Sun".

However, with the G series little other options were presented to the pilot, especially against their new primary target the western Allied Bombing Campaign.

The initial G1 was an improvement over the "F" series by carrying a pressurised cockpit and a supercharged engine the "Gustav" was to become the high altitude high performance variant of the 109, and did become the scourge of Allied Bombers above 10,000 feet.

The G1 carried the improved 20mm cannon and dual 7.92mm machine guns in the same arrangement as the F4, however, it also nearly always carried under wing gun pods or bombs.

The G2 had the same armament and engine, but without the complex pressurization system it was destined to fight between 10 and 10,000 feet.  G1's were stationed primarily in Germany, France and the Low Countries on the bomber interception role.  Whilst G2's almost exclusively went East to the Russian Front, or with tropical filters north to Scandinavia or South into Italy, Africa and the Balkans (tropical filters also helped filter snow from the air, as well as the dust of the Urals and Deserts).

The under wing gun pods optionally added 20mm, but later 30mm kits were supplied to units stationed in the defence of the Reich.  Less often were 30mm gun pods put into front line use against other fighters as the additional weight and drag of these large guns further hampered the manoeuvrability of the Gustav.

The "G" also saw the use of the Daimler Benz DB605A engine, a progressive upgrade spanning all the way back to the DB600A.

There were many more marks of "G" models, from G1 and G2 in 1943, to the G3 & G4's in 1944 - which differed in their radio installation and the use of armour plate around the pilots seat, as well as the G3 changing the default armament to a single 30mm Mk108 cannon firing through the prop, two 20mm MG 131 cannon in the upper engine cowing, firing synchronised through the arc of the prop, and then two 20mm MG151 mounted one per wing.  This much heavier default armament marked the start of an escalation in the fire power of the G series.

Later in 1944, G5 and G6 carried even higher calibre cannon armaments.  But these were the first editions of the 109 to carry the new to service 13mm MG131 Heavy Machine guns, finally doing away with the 7.92mm of old.

Many G6's never left the factories before they had an airtight cabin fitted, and were re-designated the G16.  Simpler than the pressurization system used in the G1, this airtight system consisted of a simple seal allowing the pilot to climb to altitude and still fight whilst breathing pure oxygen, a significantly simpler production processes, than the complex system in the G1.

However, breathing pure oxygen was a hazard in combat, especially with burning phosphorous tracer rounds.  Though there are anecdotal tales the pressure differential between the airtight cabin and outside atmosphere sometimes aiding escape, but sucking the pilot from his seat when he needed to bail out, though at very high altitude it was not unheard of for pilots in their chutes to pass out through lack of oxygen in the thin air.

Erla Haube canopy

In 1943 however, there had also been serious redesign carried out on the canopy, going from the steel frame and often hard to see out of early war variant to a redesigned version.  This redesign was carried out by a subcontractor, the Erla Haube company.  It was work pushed through by Adolf Galland after his movement to Jagdflieger High Command, and so the new canopy is often mistakenly referred to as the "Galland Hood".

As well as the canopy, the "G" also saw the second redesign of the cockpit layout, including new sights, new seat, additional pilot armour protection and various other facets were honed and reformed.

The biggest external hint that the "G" was completely new cowling hood, many sporting bulges to contain the larger cannon installations.  These did hamper the already poor forward view from the aircraft whilst taxiing, and were subject to complaint from pilots when aiming their shots.

However, it clearly shows the large bulges in the cowling cover

LATE WAR
Midway through the G series, after the G2, we really see the airframe progress from the mid-war to late-war generations.  As the fighters of the Reich are pushed further into the interception role.  They begin to evolve less for aerodynamic prowess and more for raw power in the climb & speed.

This loss of movement in the fighter role really saw a seed change in 109 design which continued on into the early jet age, where speed became king.

However, two more whole models of 109 were produced before war's end, first was the "H" series, which was not based on an evolution of the "G" but instead took "F" models and up rated them with the new DB601E engine which had a new high altitude supercharger and in some sub-models water injection systems.

The "H" series however was short lived in the effort for both production and upgrading, because many of the airframes were older or war weary, even when reconditioned with German engineering's high standards, there were problems with fixing the engine to the airframe sufficiently well and vibration dogged the "H" series aircraft until their retirement at wars end.

BF109H - Showing it's sleek lines in 1945.

There were only two "H" marks toyed with, converted "F" models were the generally the H0, whilst manufactured "H" series were H1 variants. The H0 being primarily for development and pre-production testing, of the envisaged H1.

By September 1944 Germany was almost completely on the back foot, defending on all sides as Italy fractured and surrendered to the allies in South, the British, Canadian and American forces moved Eastwards from the Atlantic liberating France, lending the Free-French weight to their numbers.  And the vast horde of now well organised Soviet forces poured westwards avenging the German savagery on the ground.

As such anti-bombing operations became the prime focus for the last production model 109, with the need to reach up above 41,000 feet the new "K" or "Kurfurst" series was developed.

It provided improved propeller technology to better bite into the thin air at high altitude, a new version of the DB605 engine was also developed, some quote this as the ASCM version, others simply the DB605F (I'm yet to clearly define the engine), but it was planned to develop 2000 horse power under war emergency power.

Two initial marks were made available to the Luftwaffe, the K2 and the K4, which differed with the latter having the same pressurised cockpit system as the G1.  Some K model aircraft were sent to Japan to assist their development of both high-altitude interceptors, but also instruct Japanese designers on the leaps made in pilot protection (something drastically lacking in native Japanese designs until too late in the Pacific war).

The initial K series planes also had a heavier armament, they did away with the machine guns, going with an all cannon armament of two 15mm MG151 Cannon in the upper cowling and one 30mm MG151/FF Cannon firing through the prop.

In the fully pressurised high altitude form the K4 also carried 15mm cannons in gun pods under the wings, but swapped the cowling cannon pair for a pair of 15mm heavy machine guns, which provided a higher rate of fire, aircraft were delivered as such, they were not supplied as kits in the field.

As war stresses carried to press on Germany the K6 was developed from the K4, reducing the demand for cannon armament by dropping the two 15mm cowling cannons back down to 7.92mm Machine Guns or 13mm heavy machine guns, of which there was more stock available.

The K6 began delivery to front line units in January 1945, however, by then the front line was within the borders of Germany itself and so the combat experience of the K6's were essentially poorly trained young pilots, flying from bombarded strips under extreme duress.

Even with their superior performance over previous versions they proved no match for the swarms of Allied fighters and through until the German surrender no notable successes were had with the type.

Bringing to an end the long success of the BF109 in the ruins of Germany.

For a design of 1935 the 109 served extremely well, but at wars end it was tired and 109's were not much considered as war reparations by the victorious allies.  The soviets did capture some late K models and digest their high altitude systems, parts of which are reported to have gone into the early Mig & Yak jets.  However, in the west the 109 was pawed over and for the main scrapped.

Czechoslovakia took the 109 plans and the Czech state aerofactory Avia build the S-199, which to all intents was a late 109 G airframe with a new engine.  These planes were supplied to Spain, Italy and Isreal, and it was with Isreili pilots the 109 in this guise made it's final air-to-air interceptions, with 8 kills of Egyptian and Syrian aircraft.


REVIEW
Historically the short fuel load of the aircraft was one of its biggest problems in the early war years, however one bigger problem dogged the 109 throughout it's life, a problem even I acknowledge as difficult to solve, the narrow undercarriage.  Which proved fragile and over 1,500 (2,000 by other sources) aircraft were lost to undercarriage accidents, either in landing or during take off.

This wasn't to say wide track landing gear was never tried, just it never entered production, indeed the ME209/BF109R units pre-war had wide track undercarriages to make up for the lack of view forward caused by the larger engine.

BF109F1 - testing wide track main landing gear.

Another fatal problem with the aircraft was the torque or wash from the prop, there is discussion between different sources as to what the problem actually was, whether the sheer torque generated by the engine against the light airframe caused it to want to spin anti-clockwise, or whether the slip stream of air down the left side of the fuselage caused a rudder effect.  But the problem was manifest in a strong veering during take-off and a tendency for the aircraft to want to spin anti-clockwise onto its back.

This effect was not unheard of in other planes, however, the 109 receiving its high power plant engine into squadrons used to more manageable types, like the He51, it came as a culture shock to suddenly find an engine so powerful as it wants to kill you.  Many young pilots paid the ultimate price for this tendency of the type.

As the Luftwaffe pilot training programs were cut to try and meet demand so the quality of pilots fell and both take-off & landing accidents accounted for far more pilots than in the early stages of the war.

Virgin Media - Long Eaton

What Internet speed am I paying for?... 60mbps... Sixty... And what am I getting?.... 

Two and a half... Yes, 2.5mbps...


I've tested this 6 times, three times with testmy.net and three times with http://www.broadbandspeedchecker.co.uk/... 

2.5mbps above is the fastest download speed I've seen returned...

It is a Sunday night, I know everyone will be in streaming movies, or browsing the web, but if the provider can't supply 60mpbs because their equipment in the area is saturated they should not advertise or charge for 60mpbs...

I can't play games, I can't watch YouTube and the live TV I just tried to watch, because the wife has fucking X-Factor on just does this:


And I don't blame it at 2.5mbps... But I pay for 60!

Virgin Media, do something about this!
