The F110-GE-129 is GE’s answer to the F100 competition, and it has become the engine of choice for the newest F-15 variants. With a three-stage blisk fan and advanced augmentor, it reduces complexity while improving maintainability and component life—qualities that matter when fighter fleets are expected to serve for decades .
F110-GE-129 Architecture
The primary subject of this technical guide focuses on the General Electric F110-GE-129 engine, engineered specifically for Afterburning Turbofan applications. Below is an essential digest of this powertrain configuration.
• 29,000 lbf thrust class
• Three-stage blisk fan
• Powers F-15EX
• Bypass ratio 0.76
F110-GE-129 Specification Table
29,000 lbf thrust class; bypass ratio 0.76; airflow 270 lb/sec; length 182.3 in; maximum diameter 46.5 in .
The three-stage blisk fan is a manufacturing and performance innovation: blisks (bladed disks) eliminate the need for separate blade attachment hardware, reducing weight and improving aerodynamic efficiency. The advanced augmentor manages afterburner light-off and stability across the flight envelope. GE designed the -129 with growth capacity in reserve, allowing future thrust increases without major architectural changes .
