The flat-rated TF34-GE-101 doubles the hot day thrust output over current engines, eliminating take-off gross weight limitations that preclude today's A-10 from delivering its most powerful mission punch. Other -101 performance advantages include:
- A significant reduction in takeoff distances during hot day conditions.
- Improved high altitude performance.
- 30% more acceleration capability and a 2X turn rate for improved maneuverability.
- An approximate 3X time-to-climb improvement at full combat weight.
- CONUS to European deployment in one-third the time - without tying up tanker assets and valuable manpower.
- A positive "single engine rate of climb" safety margin at maximum gross takeoff weight.
By leveraging a $400-million GE investment for commercial engine development and a solid production base, the TF34-GE-101 can be procured on an affordable Commercial Off-The-Shelf (COTS) basis.
Maintenance costs (including spares, labor and overhaul) are projected to be less than one-fourth the cost of maintaining current engines. Coupled with a lower maximum thrust rating for robust, reliable operation, significant savings can be realized over the remaining life of the A-10 fleet.
A true force multiplier, the A-10 with TF34-GE-101 engines can offload the F-16 Block 40/50 aircraft from close-air support missions and free these valuable assets to perform other critical tasks.
