GE T58 historical turboshaft family, the lightweight helicopter engine that powered Sikorsky SH-3 Sea King, Boeing CH-46 Sea Knight, S-61, HH-3, UH-3, and presidential VH-3D applications. GE's official data covers a 1,250–1,870 shaft-horsepower class and the T58-GE-16A improvement configuration; the family was produced from 1959 through 1984, while licensed support and overhaul continued for surviving operators. The civil CT58 derivative and exact dash variants remain separate records.
