The Future Vertical Lift (FVL) program will shape the United States military’s helicopter fleet of the future. Led by the U.S. Army, FVL will replace aging helicopters across the DoD services through a family of five different categories, or capability sets. FVL is truly a turning point in the next generation rotorcraft — and Lockheed Martin is ready to help lead the way.

The increased speed, maneuverability, survivability, and lethality delivered by mature X2 Technology™ demonstrated by S-97 RAIDER® and SB>1 DEFIANT™ will provide the Army and warfighting commanders day one/night one strategic options and battlefield advantages.

Key Advantages of X2 Technology™



Game-changing performance, record-breaking speed, and unparalleled maneuverability gives pilots the lethality and survivability they need to complete their missions in the highest of threat environments.


With the mission of the maintainer at the forefront, new technologies will enable advanced, self-monitoring and condition-based maintenance, reducing aircraft downtime and increasing flexibility.


Lockheed Martin brings a world of training expertise, a strong and established supply chain, and proven logistics operation to increase efficiency, reduce life cycle costs, and accelerate the development to battlefield timeline.


State-of-the-art digital design and a foundation built on X2 Technology™ provide unmatched capability growth potential, unbound by the same limits of physics holding back traditional helicopter designs.

X2 Technology™ Demonstrators

The Technology Demonstrators are being developed to maximize the knowledge gain and risk reduction toward an anticipated Future Vertical Lift acquisition program. Sikorsky is developing demonstrators for the light and medium size requirements. A Sikorsky-Boeing team is jointly producing the SB>1 Defiant™ medium size helicopter.

The X2 Advantage

X2 Technology™ is the foundation for Lockheed Martin’s support to Future Vertical Lift with its air vehicle and systems design.

Sikorsky has invested in — and proven — X2 Technology™ to illustrate its commitment to developing future capabilities that are achievable and affordable for both military and commercial organizations.

Meet Sikorsky RAIDER X™

Sikorsky, a Lockheed Martin company, introduces RAIDER X™, its concept for a fast, agile, survivable compound coaxial helicopter that will equip future aviators to address evolving peer and near-peer threats in the most difficult environments.

RAIDER X is specifically designed as a prototype for the U.S. Army’s Future Attack Reconnaissance Aircraft (FARA) prototype competition, part of the service’s effort to revolutionize its enduring aircraft fleet as part of what is known as Future Vertical Lift.


The SB>1 DEFIANT™ Joint Multi-Role Technology Demonstrator (JMR TD) helicopter is Sikorsky’s third X2 aircraft in less than 10 years. It is being designed and built by Sikorsky and Boeing and will prove the scalability of the X2 design to a 30,000-lb. class weight.

The SB>1 DEFIANT™ continues to expand its flight envelope through sorties each week, executing the mission elements required for Future Vertical Lift, most recently exceeding 100 knots and performing maneuvers at 30-degrees angle of bank at the Sikorsky Development Flight Test Center in West Palm Beach, Florida.

Innovations in Risk Reduction: Propulsion System Test Bed (PSTB)

The PSTB is used to test, and validate, the capability of all major systems of the aircraft, including the Dynamic Drive System and Rotor System, prior to flight testing.

As aircraft systems are brought online, data collection through PSTB testing occurs first in order to verify the successful integration of those systems.
