The General Electric GE38 is a gas turbine developed by GE Aviation for turboprop and turboshaft applications.

[2] Sporting a 22:1 pressure ratio, which was a record for single-spool compressors at the time, the GE27[3] was GE's unsuccessful submission to power the Bell Boeing V-22 Osprey tiltrotor aircraft.

GE formed a 50/50 venture with Garrett (then a division of AlliedSignal) to develop the turbofan variant[5] called the CFE (Commercial Fan Engines) CFE738, which used the GE27's gas generator core.

[2] One of a range of advertised GE38 unducted fan (UDF) sizes,[5] the 9,620 lbf (4,360 kgf; 42.8 kN) takeoff thrust GE38-B5 was for a time the baseline engine for the West German-Chinese MPC-75 regional airliner.

[6] The GE38 became the T407 military turboprop in partnership with Lycoming Engines for the Lockheed P-7A, with a maximum takeoff power of 6,000 shp (4,475 kW).
