Great Lakes aircraft in the FAA registry
The Federal Aviation Administration (FAA) lists aircraft under the manufacturer name "GREAT LAKES". As of October 16, 2026, the registry contains 168 valid registrations for this manufacturer. All 168 entries are fixed-wing, single-engine aircraft powered by reciprocating engines. The fleet consists of seven distinct models, with the majority of aircraft built between 1929 and 1985. Half of the registered aircraft were built in 1976 or earlier.
Great Lakes Aircraft Company was established in October 1928 after the Glenn L. Martin Company relocated from Cleveland, Ohio. The new company purchased Martin’s former factory and inherited production jigs for the T4M torpedo bomber. Great Lakes produced the TG for the Navy and the BG dive bomber. The company is best known for the 2T-1A Sport Trainer, a civilian sport and aerobatic plane. The original company folded in 1935 following the Great Depression and a lack of military contracts.
