Spitfire Mk. XIV versus FW190A
Early in1944 the Air Fighting Development Unit flew a Mk XIV Spitfire in a comparative trial against a captured Focke-Wulf 190A. The following are extracts from the official report.
SPITFIRE XIV VERSUS FW 190A
Maximum Speed: From 0-5,000 feet [0-1525 metres] and between 15,000-20,000 feet
[4573-6100 metres] the Spitfire XIV is only 20 mph [32 km/hr] faster than the FW190;
at all other heights it is up to 60 mph [97 km/hr] faster.
Maximum Climb: The Spitfire XIV has a considerably greater rate of climb at all altitudes.
Dive: After the initial part of the dive, during which the FW 190 gains slightly, the Spitfire XIV has a slight advantage.
Turning Circle: The Spitfire XIV can easily turn inside the FW 190. In the case of a right-hand turn, this difference is not so pronounced.
Rate of Roll: The FW 190 is very much better.
Conclusions: In defence, the Spitfire XIV should us its remarkable maximum climb and turning circle against enemy aircraft. In the attack it can affort to 'mix it' but should beware of the quick roll and dive.
If this maneuver is used by a FW190 and the Spitfire XIV follows, it will probably not be able to close
the range until the FW190 has pulled out of its dive.
