The Curtiss Hawk II was an export variant of the F11C-2 Goshawk which saw U.S.Navy service. This is one of two supplied to Germany as follows:- "Though not interested in politics, WW1 ace Ernst Udet joined the Nazi party in 1933 when Hermann Göring promised to buy him two new Curtiss Hawk IIs (D-3165 and D-IRIK). The aircraft were used for evaluation purposes and thus indirectly influenced the German idea of dive bombers, such as the Junkers Ju 87 (Stuka). Udet used D-IRIK (c/n H.81) in aerobatic exhibitions held during the 1936 Summer Olympics, the aircraft survived the war, was eventually found in a field outside Kraków." It has now been restored and is on display in the new entrance building at the Muzeum Lotnictwa Polskiego Kraków, Poland.
