Excellent post. I particularly liked the link to the USN tests. As the
Corsair's opponent was almost exclusively Japanese, it must have been a
revelation to find there was an airplane it could outturn (okay, there was
the P-47).

The impact of a weapon system with an effective range of perhaps 1500 feet
skews the weighting of A/C performance characteristics quite a bit when
compared to modern machinery. But then as now, speed was life.

In fairness I should mention that Eric Brown, who'd flown all three
extensively, reached a different conclusion than this USN comparison. Re the
Corsair II (F4U-1A with clipped wingtips) vs. the FW-190A-4, he wrote:

"This would be a contest between a heavyweight and a lightweight fighter, with
virtually all the advantages on the side of the latter. Having flown both a/c
a lot, I have no doubt as to which I would rather fly. The FW-190A-4 could
not be bested by the Corsair.

"Verdict: The FW-190A-4 was arguably the best piston-engine fighter of World
War II [Note: he probably means the FW-190 series. Later in the book, when
rating the best performing piston-fighters of WW2 , he rates the Spit XIV
number one with the inline-engined FW-190D-9 just a nose behind, and the P-51D
(Mustang IV) a tad behind that, deliberately ignoring operational issues such
as range]. It is a clear winner in combat with the Corsair."

F6F-3 vs. FW-190A-4:

"This would be a showdown between two classic fighters. The German had a
speed advantage of 30 mph, the American a slight advantage in climb. Both
were very maneuverable* and both had heavy firepower. By 1944 the FW-190 was
a little long in the tooth, while the Hellcat was a relative newcomer; still,
the superb technology built into the German fighter by Kurt Tank was not
outmoded. The Hellcat had broken the iron grip of the Zeke in the Far East,
but the FW-190A-4 was a far tougher opponent.

"Verdict: This was a contest so finely balanced that the skill of the pilot
would probably be the deciding factor."

*A somewhat odd statement, as the Hellcat had the typically mushy Grumman
ailerons. But it could certainly out-turn the 190.
