F110GE129

F110GE129 is a variant of GE Aviation’s F110 family of two-spool, afterburning turbofan engines designed for combat aircraft. It represents an advanced version of the F110-GE series, optimized to deliver higher thrust, improved reliability, and extended maintenance intervals for its designated platforms.

The engine features a modern propulsion architecture with full authority digital engine control (FADEC), enabling precise fuel management and performance monitoring. It uses an axial-flow compressor, a robust combustor, and a high-efficiency turbine, combined with a variable-geometry convergent-divergent nozzle to optimize thrust across flight regimes. The F110GE129 is typically rated to produce around 29,000 pounds of thrust in afterburner (approximately 129 kN), with a non-afterburning thrust suitable for subsonic flight, while emphasizing durability and ease of maintenance.

Applications and operators for the F110GE129 include select variants of the F-15 Eagle family. In particular, it powers the F-15K Slam Eagle operated by the Republic of Korea Air Force and the F-15SG operated by the Republic of Singapore Air Force. The configuration supports multi-role air superiority missions and long-range strike capabilities, benefiting from the engine’s reliability and performance under operational conditions.

Development and service history date to the early 2000s, with GE Aviation supplying the engines under international procurement programs. The F110GE129 is commonly deployed with dedicated maintenance and upgrade plans to sustain high mission readiness for its operator fleets.
