Specifications

The Fw-190 was one of the greatest fighters of WWII. Designed by Dr. Kurt Tank, it built as a sturdy fighter-interceptor to augment the Messerschmitt ME-109.  It made its first flight on June 1, 1939 and first saw combat over northwestern France in September 1941.
 

Aircraft - FW-190 (German)

For the most part, American aerospace testing was done on American aircraft.  However, beginning with WWI, whenever the United States obtained examples of foreign aircraft - either from friendly countries through cooperative arrangements or from enemies via capture or defection- they were likely to wind up at McCook Field or Wright Field for a thorough evaluation which included flight testing if possible. 

"During WWII evaluations at Wright Field included allied aircraft like the Russian Yak-9 and the British Spitfire and Mosquito, and enemy aircraft including the German JU-88, ME-109, FW-190, ME-262, and the Japanese Zero.  The end of the war brought large numbers of captured aircraft for evaluation.  As with other test flight activities, much of the foreign aircraft evaluation moved to Muroc Air Base (later Edwards AFB) after the war, but even then the occasional foreign aircraft came to the Miami Valley for testing, as a MiG-15 (courtesy of a North Korean defector) at Patterson Field attests."
