DEFIANT X®

An advanced utility helicopter and air air-assault weapon system

The DEFIANT X helicopter is Lockheed Martin Sikorsky-Boeing entry in the U.S. Army’s Future Long-Range Assault Aircraft (FLRAA) competition. The next-generation aircraft is planned to be the fastest, most maneuverable assault helicopter ever built.

The FLRAA program enables the Army to develop a new helicopter to replace its aging fleet of UH-60 Black Hawks by 2030 The DEFIANT X is an agile, maneuverable aircraft that flies twice as far and twice as fast as the Black Hawk helicopter it will replace — and sits in the same operational footprint.

As part of the broader Future Vertical Lift (FVL) initiative, FLRAA will provide the Army and other operators an extremely versatile aircraft that can accomplish a wide range of missions including tactical assault, medium-lift and medical evacuation.

With these capabilities – and more – the Army will be able to maintain its technology edge and ensure its readiness to counter any transregional, multi-domain and multifunctional threats U.S. servicemembers will face in the decades to come.
