this was actually an ex Russian Machine (I know many know that) however remember my previous about RAF aircraft in the FS serial block being sent to Russia? Well originally this was FS202to Finland...

Sorry, my roundel recognition skills leave something to be desired. Who is flying these planes?one more operator

According to Geust, it was the only P-40 (P-40M, No.43-5925) captured by the Finns after a Soviet pilot (from the 191st IAP of the 275th IAD of the 13th Air Army ) got lost while flying from airfield to airfield and landed on ice on the Finnish side of the front.to Finland...
Huh.
It's too bad the Commonwealth didn't license produce the P-40. Hindustan Aeronautics Limited (HAL) assembled kits of the Curtiss P-36, but that's about it.Just about all Commonwealth countries flew the P-40.
The AVG reportedly used the over boost far much than recommended. The Pilots notes on the Tomahawk (and the P-40B/C) suggest take off at maximum manifold pressure of 41 in. Hg, Max Emergency is 37.2 in. Hg and Max Continuous being 33.7 in. Hg. – there is some diary entries and official docs that show the AVG using significantly more (in the 50-60 region) When you do that to engines, it's not a poorly built engine that's given way, it's just you've taken it beyond its tolerances and engine failures are not surprising
My thoughts – seeing all I do is research the P-40.
Overall, the P-40 did what was asked of it, its limitations were large but could be mitigated against (as the AVG showed). It wasn't perfect, but it was a sound, solid design for its time (1939), and relatively forgiving (except ground loops). It carried a decent load for bombing (hence they got nick-named Kitty bombers as they could lift 2000lb loads for a short distance). Later aircraft outclassed it, there's no doubt, but wars have a habit of really expediting research, remember the bi-plane was still in service in 1942…….so it was actually quite a good aircraft, just never going to be a P-51, FW190 etc......

On the 10th Jul the AVG officially transferred their aircraft and holdings across to the USAAF.
You have to be careful here. The AVG didn't just fly Tomahawks. Boosting to 50-60" Hg became normal for the Kittyhawk types, in fact 56" or 57" Hg became the standard WEP rating for P-40E for 1942

I agree the V-1710-33/-39 and later engines could and did take the higher boosts, just pointing out that at the time the AVG were using them they were not cleared for higher boosts (plus the length of time that boost was applied).
The AVG did have a number of aircraft that had a trip or three to the repair shops, but not often due engine failure (although they did have a number of engines quit on them). Having the ability to change out an engine because you have a issue would certainly assist here (due to numbers of spares) - in most other areas this was not an option, and a number of aircraft lost due to this.
I'm going to say that whilst I love the P-40 (she's the other woman in my life according to OIC Homefront), I also try to inject some reality into my research - I note her positives and her negatives, and could be like the aficionados spinning on how good she was - however I like to apply a critical eye to my assessment of her combat record and leave the fluff to others.
Yes concur the P-40 was the highest scorer in the CBI, but how many groups flew in the CBI with other aircraft and for how long? The P-40 was almost exclusively the only game in town for the best part of 2 years,
and even when other types turned up she stayed in operation (and the number of combats reduced as well)........ Again I agree the P-40F/K/L USAAF equipped Squadrons and Groups did well in the ME
- their claims vs losses were very high (all claimed in good faith) - the reality of their Kill/losses ratio is somewhat different.
Similarly the other Units that flew the type in the Middle East and Italy, as well as the Solomons, NG and the Pacific - they all did well, yet nothing spectacular - again a solid showing.
Overall the Kill/loss ratio for the P-40 is certainly in the positive at a time when other types were having a hard time (Hurricanes/Buffalos etc), and as I said a P-51 she's not, but certainly a solid combat aircraft of her time.
I know cliché but one of her biggest saving graces was she could take punishment and come home meaning the pilot living to fight another day......... just how solid? well I have a couple of aircraft in my records that took major damage on multiple occasions only to make it home/or be repaired after being shot down or force landed - some of the damage you just shake your head and wonder how...... we see incidents of mid airs collisions (deliberate or not), yet the P-40 makes it home, aircraft shot down multiple times, another case of a pilot bounced a P-40 into the ground at over 350mph, breaking the aircraft into 4 pieces - and walking away - I think the record is an aircraft shot down, force landed or damage in a significant way 6 times in its life time.
Overall Excellent fire power (still standard at the end of the war), good load capacity, long range (with tanks), and having attributes, that used well, could allow the Pilots to hold their own in engagements or break off combat relatively easily (if they had the height). She may not be able to turn with a zero, out dive a P-47, have the range of P-38, the overall abilities of a P-51 or the fire power of a Beaufighter - but she was there when the Allied Air Forces needed her..... the other more glamorous and capable types in most cases weren't even at prototype stages.......
ShortroundBut in regards to the AVG, while they got around 30 P-40Es they started showing up in March 1942. First 6 in late March?
50 aircraft had been Allocated in Jan 1942. The problem was delivery. Most were Shipped to Africa and then flown across Africa on through the mid-east and into India. I have no idea how many got "lost" on the way.
The first P-40K left the production line in May 1942, the first (42-45722) is retained at the Factory for testing. Chances of a P-40K making to China to serve in the AVG are about zero.
The US Army and Allison were doing a lot testing of higher boost levels in 1942. It seems to have taken until Dec 1942 for the WEP settings to become "official" (printed in manuals?) although it seems that planes were being tested at the soon to be published limits in Oct-Nov.
There is no question they over boost the engines. But in regards to the AVG, while they got around 30 P-40Es they started showing up in March 1942. First 6 in late March?

A problem with the AVG is what were they using for fuel? The -33/39 engines were rated for US 100 octane fuel, which was pretty much 100/100, it varied a bit on the 2nd number.
British 100 octane was around 100/115-120 in 1940. In 1941 they were using 100/130 but the question is where and when.
The US (or Allison) was using 100/125, at least for testing, in the spring of 1941. But 100/125 was never adopted by the British.
The 100/125 standard was soon superseded by the 100/130 standard (joint US/British) and there were at least 3 different standards for 100/130 by the beginning of 1943. All of the 100/130 was supposed to perform in engines the same with different amounts of components/compounds to make manufacture easier.
100/130 will allow a lot more boost to be used than 100/100 but that is just for detonation limits. Breaking con rods or crankshafts due to excess power is something else.
Unfortunately "100" became short hand for 100/130 in many reports. AVG was disbanded 3-5 months before WEP became a standard or "official".
Not even an Fw190A could.She may not be able to turn with a zero

Robert DeHaven, 49th FG Ace with 10 victories on the P-40 (through Jan 1944), and then got four more on P-38s, said the following:Not even an Fw190A could.
However, once the P-40 pilots realized that getting into a turning fight on an A6M or KI-43's terms meant death, they upped their game to energy fighting.
The P-40 had a great turning radius and roll rate at higher speeds, where the KI-43 and A6M were at a disadvantage and the P-40 drivers used this to their advantage.
