General Electric CT7-8A6
Active General Electric CT7-8A6 exact certified turboshaft variant in the CT7-8 family and the two-engine powerplant of the Sikorsky S-92/S-92A+ helicopter family. Lockheed Martin's S-92A+ offshore technical sheet lists the pair at 2,695 shp (2,010 kW) for five-minute takeoff and 2,637 shp (1,966 kW) for 30-minute power under uninstalled sea-level ISA conditions; the typed shaft-power field stores the derived per-engine five-minute takeoff value of 1,005 kW. Lockheed Martin's 2026 S-92A+ production update also describes increased CT7-8A6 shaft horsepower for hot- and high-altitude performance.
