In the beginning, many of Seversky Aircraft's designers were Russian and Georgian engineers whom Seversky had rescued from Joseph Stalin's purges by bringing them to the United States, including Michael Gregor and Alexander Kartveli, who would go on to design many of Republic's most famous aircraft.

Alexander Kartveli was called to the Army's Experimental Aircraft division and told of the new requirements, and that the P-44 would not be ordered in its current configuration.

In 1951, Alexander Kartveli began to design a replacement for the F-84 Thunderjet.

Alexander Kartveli, born Alexander Kartvelishvili, () 1896 – 1974 ) was an influential aircraft engineer and a pioneer of American aviation history.

Alexander Kartveli was born in Tbilisi, Georgia, then part of the Russian Empire, into a noble Georgian family.

The P-47 design team headed by Alexander Kartveli, Republic Aircraft Corporations's chief engineer, originally presented a design that was to be powered by a 1, 150 hp Allison V-1710-39 engine with an armament of only two 0. 50 inch machine guns. 1 A contract was awarded by the USAAC in November 1939, and for an even lighter XP-47A, but as intelligence was coming back from the war in Europe, it was becoming apparent that the performance goals of the XP-47 program were already inadequate.

n 1944, Republic Aviation's chief designer, Alexander Kartveli, began working on a turbojet-powered replacement for the P-47 Thunderbolt piston-engined fighter.

Led by Alexander Kartveli, the design team produced an aircraft centered on a large engine and able to achieve high speeds.

Notable fact: Georgian call themselves " kartvelebi " and the surname of Alexander comes from " Kartveli ".
