Planes USA F-47D
The Republic F-47D was an American fighter-bomber of the WWII era. It was one of the main USAAF fighters of WWII, especially effective as a fighter-bomber. The F-47 was also sent to the USSR via the lend-lease program. It was designed at Republic Aviation by two emigrants from the Russian Empire, Alexander Seversky and Alexander Kartveli.
The official designation of the F-47, like that of many other Republic aircraft, is related to the word Thunder. However, the F-47's unmatched dimensions and weight led to the F-47 being nicknamed the Jug. Another informal nickname, more common during WWII, is Bolt or T-Bolt. The most mass-produced variant of the F-47 was the F-47D with a teardrop canopy. The variant was in development as early as 1941 and the first order for 850 F-47Ds was placed in late 1941. Many more Thunderbolts would be built during the war, making it the most mass-produced US fighter of WWII by 1945.
