Soviet high altitude fighters?

[Civettone]

Do not forget the Bell P-63! Two-stage supercharger and ceiling well above 13 km.


There were also a Yak-9 prototype version optimized for high altitude. Also several other prototypes; the Russians were clearly prepared for a German high-altitude campaign. So were the British (Westland Welkin) but it never happened.

As you have probably read, Finland was very interested in acquiring MiG-3. There was a contract signed with Germany in 1942 for the delivery of 15-22 samples. Nothing came out of this as they were destroyed in an air raid. Here is a performance comparison with 2 typical Finnish fighters from that period.

The Finnish data match well Soviet's at high altitudes, but not lower. The climb rate of the Soviet model is superior at high altitudes, but at low level the Curtiss' is exceptional.

1. There is no "Finnish data" on MiG-3, as FAF never had any.
2. FAF had B-239 (or F2A-1) with a top speed of 480km/h.
3. FAF 75A Hawk were usually with Twin Wasps (R-1830), top speed about 440km/h or less.

I was referring to the leaflet below. Is it from a German test?

Do you have a FAF test of B-239/75A Hawk. It sounds a bit slow for B-239 as some equipment was not used in Finnish version. Of course, other stuff was added... Maximum velocity for Hawk is also quite low.

MiG-3 numbers were most certainly from Germany.
Remember that that F2A-2/3 had some some 200hp more hp.
FAF Hawks had low octane fuel, and (mostly) Twin Wasps. (1,200hp) Cyclone variants were closer to B-239.
Brewster speeds were spot on with factory numbers, very unlike Hawk75 (and many other FAF fighters for that matter).
