- Rolls-Royce began AE 1107F engine testing to support prototype delivery for the U.S. Army’s MV-75 Future Long Range Assault Aircraft program.
- Each MV-75 FLRAA is planned to use two AE 1107F engines, with testing conducted at Rolls-Royce’s Indianapolis facility.
Rolls-Royce has begun testing its AE 1107F engines to support delivery of prototypes for the U.S. Army’s MV-75 Future Long Range Assault Aircraft (FLRAA), the company said.
According to a company statement, the AE 1107 engine test campaign is intended to support prototype aircraft for the MV-75 FLRAA, a next-generation platform designed to provide greater speed, range, and lethality for future Army aviation units. Each MV-75 FLRAA is planned to be powered by two Rolls-Royce AE 1107F engines.
As noted by the company, the AE 1107F represents the latest evolution of a powerplant family that has been in U.S. military service for decades. Rolls-Royce says the engine is designed to deliver high power density, cyber-compliant controls, and survivability features tailored to modern combat environments.
Candice Bineyard, director of U.S. business development and future programs for Rolls-Royce Defense, said engine testing is a key step toward fielding the new aircraft.
“We continue working closely with the U.S. Army and our industry partners to deliver an ultra-modern propulsion solution with proven, low-risk AE 1107F engines and a fully integrated system design,” Bineyard said. “Engine testing represents the next critical milestone in bringing this revolutionary capability to our service members.”
Rolls-Royce said testing is underway at its advanced manufacturing campus in Indianapolis, the company’s largest U.S. facility. The site supports a range of military programs and includes test infrastructure designed for current and future propulsion systems.
Company says it has invested more than $1 billion over the past decade in technology enhancements, facility upgrades, and test capabilities at the Indianapolis campus. These investments are intended to support major U.S. Department of War programs, including the MV-75 FLRAA effort.
The AE 1107F draws from an established engine family with a long operational history. According to Rolls-Royce, AE-series engines have accumulated more than 90 million flight hours across 16 commercial and military platforms. The AE family is built around a common core architecture, with the company stating that about 80 percent of components are shared across variants.
Rolls-Royce says this common core approach reduces technical risk, shortens development timelines, and supports faster introduction of new engine variants. It also allows the company to sustain an active supply chain that supports production and long-term maintenance for the broader AE engine fleet.
The AE 1107 has already seen extensive use across U.S. military services. The engine powers multiple variants of the V-22 Osprey operated by the U.S. Marine Corps, U.S. Navy, and U.S. Air Force. A marinized version of the engine, known as the MT7, is also used to power the U.S. Navy’s Ship-to-Shore Connector landing craft.
The MV-75 FLRAA program is expected to replace portions of the Army’s current rotary-wing fleet with an aircraft designed for longer range and higher cruise speeds than legacy helicopters. The Army has said FLRAA is central to its future air assault and air movement concepts, particularly in environments where distance and response time are critical factors.
Rolls-Royce’s role in the program places propulsion development alongside airframe, avionics, and mission systems as one of the key components being matured ahead of prototype delivery. Engine testing is intended to validate performance, reliability, and integration before aircraft enter broader flight evaluation.
