• Rolls-Royce has begun ground testing the AE 1107F turboshaft engine for the US Army's Future Long-Range Assault Aircraft (FLRAA).
• The engine will power Bell's MV-75 tiltrotor, selected to replace the UH-60 Black Hawk.
• Testing is underway at Rolls-Royce's Indianapolis facility.
• The AE 1107F engine is a derivative of Rolls-Royce's AE engine family.
• Each MV-75 will be powered by two AE 1107F engines.

This development may indicate the US Army's commitment to rapid progress on the FLRAA program, which aims to deliver significantly greater speed and range than legacy helicopters. The use of Rolls-Royce's AE 1107F engine suggests a focus on reliability and high-power output, which could benefit the MV-75's performance and competitiveness. However, the timeline for FLRAA's entry into service remains uncertain, and the program's overall value could exceed $70 billion.
