Honeywell engine selected to power Sikorsky-Boeing Defiant X helicopter



Lockheed Martin Sikorsky and Boeing have selected Honeywell to supply its new HTS7500 turboshaft engine for the Defiant X helicopter. The Defiant X Advanced Helicopter System is Sikorsky-Boeing’s entry for the Future Long-Range Assault Aircraft (FLRAA) competition ) of the US Army.

The US military launched the FLRAA program in 2019 to develop a new utility helicopter that will replace the Sikorsky UH-60 Black Hawk from 2030.

According to Sikorsky and Boeing, the Defiant X will be the fastest and most maneuverable assault helicopter in history. It can fly twice as far and as fast as the Black Hawk helicopter and is currently being tested in a digital combat environment, where it continues to prove its unrivaled range and survivability.

The HTS7500 turboshaft engine is the newest and most technologically advanced model in the Honeywell military engine family. The HTS7500 is an extremely reliable engine designed to thrive in austere environments and to keep military personnel safe. It improves mission readiness and exceeds mission power and fuel burn requirements.

The new engine is equipped with a modernized control system, which enables a highly secure flow of engine data. The control system improves operating capabilities, reduces life cycle costs and ensures engine health with its digital roadmap. The HTS7500 engine promises 42% more power output than the T55 while consuming up to 18% less fuel and promising low maintenance cost.

“We are committed to the U.S. military’s emphasis on modernization and multi-domain operations, and the selection of Honeywell’s latest engine technology for the Defiant X is proof of that commitment,” said Ricky Freeman, President, Defense and Space, Honeywell Aerospace. “The HTS7500 checks all the right boxes for the Lockheed Martin Sikorsky-Boeing team and the military, and we are excited to play a part in the future of vertical lifting for our military customer and the Defiant team. “

Sikorsky-Boeing submitted its proposal for the Defiant X in September 2021. Last month, the Defiant X technology demonstrator SB-1 Defiant completed successful mission profile test flights.
