Fairchild Republic Co.

Fairchild Republic Co. was the Republic Aviation division that became part of Fairchild Hiller in 1965 and later Fairchild Industries, best known for producing the A-10 Thunderbolt II attack aircraft and the prototype T-46A Eaglet jet trainer.

Fairchild Republic Co. was the Fairchild Hiller and Fairchild Industries aircraft division formed from Republic Aviation after the 1965 acquisition. Smithsonian archival material uses Republic Aviation Division and Fairchild Republic for the same organization, placing it inside the wider Fairchild corporate aircraft lineage.

The division's best-known production program was the A-10 Thunderbolt II, a close-air-support aircraft credited by the U.S. Air Force to Fairchild Republic. In the 1980s it also pursued the T-46A Eaglet, a light jet trainer selected for the Air Force's T-37 replacement competition before cancellation left the program at the prototype stage.

Fairchild Republic's later history was shaped by the contraction of Fairchild's aircraft business. The Washington Post reported in 1983 that the Hagerstown aircraft plant would close as A-10 production phased down, and Smithsonian corporate history records the Republic division's 1987 shutdown when Fairchild Industries ceased commercial and military aircraft manufacturing.

Public sources use Fairchild Republic, Fairchild Republic Co., and Republic Aviation Division for the same 1965-to-1987 aircraft division within Fairchild Hiller/Fairchild Industries. No rights-clear company-facility image was verified, so the page uses a public-domain A-10 product image.
