Since the serial production of the new R-2800 Double Wasp engine, which was supposed to equip the developed R-47, had not yet been deployed, to load the conveyor of the Republic plant in Farmingdale USAAC at the end of 1940 ordered another batch of 54 P-43 Lancer instead of canceled order for 80 R-44.

Serial numbers of virtually identical YP-43 aircraft were from 41-6668 to 41-6721. The aircraft were powered by a Pratt & Whitney R-1830-47 14-cylinder air-cooled radial engine with a turbocharger, which developed a take-off power of 1200 hp. The first P-43 was delivered on May 16, 1941, the last aircraft was delivered to the army on August 28, 1941.

In 1942-1943, 108 vehicles were delivered to China. In total, about 250 fighters of various modifications were built.

Republic P-43B / D / E Lancer is a reconnaissance version of the P-43 single-seat fighter. Designed in KB "Republic Aviation Corporation" under the direction of A.M. Kartveli. The armament is the same as that of the P-43 / 43A - two 12.7 mm machine guns. The lead production copy of the P-43 was tested in May 1941. The aircraft was built at the Republican plant in Farmingdale. About 150 reconnaissance vehicles were produced. Photo reconnaissance aircraft based on the P-43 / P-43A have been in service in the United States since the summer of 1941, in Australia since August 1942. All modifications of the P-43 were discontinued in 1942.
