P-43 A-1 American fighter

The Republic P-43 Lancer was a single-engine, all-metal, low-wing monoplane fighter aircraft built by Republic, first delivered to the United States Army Air Corps in 1940.[1] A proposed development was the P-44 Rocket. While not a particularly outstanding fighter, the P-43A had a very good high-altitude performance coupled with an effective oxygen system. Fast and well-armed with excellent long-range capabilities, until the arrival of the Lockheed P-38 Lightning, the Lancer was the only American fighter capable of catching a Japanese Mitsubishi Ki-46 "Dinah" reconnaissance plane at the speeds and heights at which they flew.
