The Seafire was a carrier-based adaptation of the Spitfire that served in the Fleet Air Arm from 1942 through to the mid-1950s.

Rolls-Royce AE 2100 2100P. The engine uses new six-bladed Dowty propellers for use on the 50-seat Saab 2000 and the Lockheed Martin C-130J Super Hercules military transport. Each engine develops 4,591 shaft horsepower. Rolls-Royce AE 2100 The Rolls-Royce AE 2100 is a turboprop developed by Allison Engine Company, now part of Rolls-Royce North America. A derivative of the Allison AE 1107C-Liberty (Rolls-Royce T406) turboshaft engine, the AE 2100 shares the same high-pressure core as that engine, as does the Rolls-Royce AE 3007 turbofan. The engine is a two-shaft design, and was the first to use dual FADECs (full authority digital engine control) to
