The General Electric T58 was a US turboshaft engine developed for helicopter use. First run in 1955, it remained in production until 1984, by which time some 6,300 units had been built. It was the first turbine engine to power a helicopter in the United Sates, and the first turbine engine to gain FAA certification for civil helicopter use. The engine was licence-built and further developed by de Havilland in the UK as the Gnome, and also manufactured by Alfa Romeo and IHI. GE redirects here. ...

Development commenced with a 1953 US Navy requirement for a helicopter turboshaft to weigh under 400 lb (180 kg) while delivering 800 hp (600 kW). The engine that General Electric eventually built weighed only 250 lb (110 kg) and delivered 1,050 hp (780 kW) and was soon ordered into production. First flight was on a modified Sikorsky HSS-1 in 1957 and civil certification for the CT58 variant was obtained two years later.
