DEFIANT X will be the fastest, most maneuverable and survivable assault helicopter in history.

«Team DEFIANT’s strength is built on the experience of Sikorsky and Boeing, and a commitment to Army Aviation», said Mark Cherry, vice president and general manager of Boeing Vertical Lift. «Honeywell’s history with Boeing and the U.S. Army makes us even more confident that DEFIANT X is the best fit for the Army’s total mission».

«DEFIANT X is a transformational aircraft, and Honeywell is giving us a transformational engine to power it», said Paul Lemmo, president of Sikorsky. «DEFIANT X is optimized for operational effectiveness, sustainment and interoperability with the enduring fleet, and will transform the Army».

DEFIANT X is a complete weapon system that builds on the handling qualities and capabilities proven by the team’s technology demonstrator, SB>1 DEFIANT. It flies twice as far and fast as the venerable Black Hawk helicopter it is designed to replace. Currently undergoing testing in a digital combat environment, the aircraft continues to prove itself as the most survivable platform for mission requirements.

«Honeywell is excited to be a part of Team DEFIANT and proud to play a part in the future of vertical lift for the U.S. Army», said Ricky Freeman, president, Defense & Space at Honeywell Aerospace. «We’re confident our HTS7500 engine on the DEFIANT X platform will provide the Army with an agile, fast and maneuverable platform that will help ensure overmatch capability in the future battlespace».

Sikorsky-Boeing submitted the proposal for DEFIANT X for the U.S. Army’s Future Long-Range Assault Aircraft in September 2021. Contract award is expected this year.

Uninhabited flight

The DARPA Aircrew Labor In-Cockpit Automation System (ALIAS) program completed a first ever flight of a UH-60A Black Hawk helicopter without anyone onboard. Sikorsky, a Lockheed Martin company, completed 30-minutes of uninhabited flight with the Optionally Piloted Vehicle (OPV) over the U.S. Army installation at Fort Campbell, Kentucky on February 5th. An additional uninhabited flight was also conducted on February 7th.

The Black Hawk was retrofitted with Sikorsky MATRIX autonomy technologies that form the core of ALIAS and can change the way aviators and air crews execute their missions by providing assistance when flying with limited visibility or without communications.

ALIAS is a flexible, extensible automation architecture for existing manned aircraft that enables safe reduced crew operations, which facilitates the addition of high levels of automation into existing aircraft. It also provides a platform for integrating additional automation or autonomy capabilities tailored for specific missions.

«With reduced workloads pilots can focus on mission management instead of the mechanics», said Stuart Young, program manager in DARPA’s Tactical Technology Office. «This unique combination of autonomy software and hardware will make flying both smarter and safer».

The ALIAS program has leveraged the considerable advances in aircraft automation systems over the past 50 years, as well as similar advances in remotely piloted aircraft. Even in today’s most automated aircraft, pilots must still manage complex interfaces and respond to unexpected situations.

ALIAS aims to support execution of an entire mission from takeoff to landing, including autonomously handling contingency events such as aircraft system failures. Easy-to-use interfaces facilitate supervisor-ALIAS interaction.

«With ALIAS, the Army will have much more operational flexibility», said Young. «This includes the ability to operate aircraft at all times of the day or night, with and without pilots, and in a variety of difficult conditions, such as contested, congested, and degraded visual environments».

The Army is currently exploring potential use cases for technologies such as ALIAS, including those outlined in the U.S. Army’s Future Vertical Lift (FVL) program.

Within the next month, the ALIAS program plans to conduct the first flight of a fly-by-wire M-model Black Hawk at Fort Eustis, Virginia.

First Uninhabited Black Hawk Flight

Nine Additional CH-53K

Prioritizing affordability and utilizing advanced manufacturing techniques, Sikorsky, a Lockheed Martin company, will build nine additional CH-53K King Stallion aircraft at a lower unit price than previous lot buys, resulting in significant savings for the U.S. government and taxpayers. The company’s experienced supply chain coupled with its active digital approach drives speed and affordability throughout design, development, production, and sustainment.

CH-53K King Stallion
Stratford, Conn: The CH-53K King Stallion helicopters will be built at Sikorsky headquarters in Stratford, Connecticut, leveraging the company’s digital build and advanced technology production processes

The CH-53K King Stallion will further support the U.S. Marine Corps in its mission to conduct expeditionary heavy-lift assault transport of armored vehicles, equipment and personnel to support distributed operations deep inland from a sea-based center of operations, critical in the Indo-Pacific region.

These nine helicopters are part of 200 aircraft Program of Record for the U.S. Marine Corps with deliveries beginning in 2025.

«By embracing resilient, predictive logistics and sustainment, we are enabling CH-53K King Stallion crews to make smarter, faster decisions, to increase reliability, and improve readiness and material availability at reduced burden to the fleet», said Bill Falk, Sikorsky Director, CH-53K King Stallion programs. «After 50 years of supporting the CH-53E Super Stallion, Sikorsky has a deep understanding of the heavy-lift mission and an enduring partnership with the U.S. Marines Corps enabling our team and our proven supply chain to offer tailored solutions resulting in more efficient missions».

 

Building to Deliver

The aircraft will be built at Sikorsky headquarters in Stratford, Connecticut, leveraging the company’s digital build and advanced technology production processes.

The factory is active with seven CH-53K King Stallion aircraft in build, and there are 47 more aircraft in various stages of production.

Sikorsky has made significant investments in workforce training, tooling, and machinery to increase the number of aircraft built and delivered year over year.

In total, Sikorsky has delivered five operational CH-53K King Stallion heavy-lift helicopters to the U.S. Marine Corps in Jacksonville, North Carolina, with four more planned for delivery this year.

 

Marines Flying CH-53K King Stallion in Fleet Environment

The CH-53K King Stallion program operated by the U.S. Marine Corps entered Initial Operational Test and Evaluation in 2021 and is set to conclude in 2022.

Sikorsky has a strong foundation to support the CH-53K King Stallion because the company already provides the U.S. Marines with predictive maintenance on the legacy CH-53E Super Stallion by utilizing the Fleet Common Operating Environment (FCOE) enabling the shift from reactive to predictive maintenance.

The CH-53K King Stallion aircraft is equipped with Integrated Vehicle Health Management System (IVHMS), which will transition the U.S. Marines from fixed interval to on-condition maintenance resulting in lower maintenance crew hours, reduced life cycle costs and increased aircraft readiness.

Lockheed Martin is working with the U.S. Navy on a performance-based logistics contract that expands from the CH-53E Super Stallion to add the CH-53K King Stallion with a contract award expected this year.

FLRAA Mission Profile

The Lockheed Martin Sikorsky-Boeing SB>1 DEFIANT successfully completed FLRAA mission profile test flights, including confined area landings and low-level flight operations. These flights validate DEFIANT’s relevancy to the Army’s mission, providing agility at the objective (also known as the «X»), and increased survivability, all while reducing pilot workload. View the video of the latest flight testing.

«We fully demonstrated DEFIANT’s ability to execute the FLRAA mission profile by flying 236 knots in level flight, then reducing thrust on the propulsor to rapidly decelerate as we approached the confined, and unimproved, landing zone», said Bill Fell, DEFIANT chief flight test pilot at Sikorsky and a retired U.S. Army Master aviator. «This type of level body deceleration allowed us to maintain situational awareness and view the landing zone throughout the approach and landing without the typical nose-up helicopter deceleration. This confined area was extremely tight, requiring us to delay descent until nearly over the landing spot, followed by a near-vertical drop. We landed DEFIANT precisely on the objective with little effort as we descended into this narrow hole while maintaining clearance on all sides».

SB>1 DEFIANT is the technology demonstrator proving out transformational capabilities for the DEFIANT X weapon system, the Sikorsky-Boeing team offering for the U.S. Army’s Future Long-Range Assault Aircraft (FLRAA) competition as part of the Army’s Future Vertical Lift program. DEFIANT X will enable crews to fly low and fast through complex terrain, where Army aviators spend most of their time. It will extend capabilities of Army Aviation on the modern battlefield – and is designed to fit in the same footprint as a BLACK HAWK. With DEFIANT X, the U.S. Army will deliver troops and cargo in future combat at twice the range of the current fleet.

«It’s what we call building combat power rapidly, and aircraft like the DEFIANT X can do that», said Tony Crutchfield, retired U.S. Army Lieutenant General and now vice president of Army Systems at Boeing. «In the Pacific, it’s even more important because your lines of operation are going to be dispersed over a wide area; you’re going to have these small bases and supply lines that’ll be positioned either on ships or on islands. You’re going to want to move more assets, maneuver in confined terrain and survive to build that combat power faster than your adversary can – so you can win».

DEFIANT X incorporates Sikorsky X2 Technology to operate at high speeds while maintaining low-speed handling qualities. This critical capability provides pilots with increased maneuverability and survivability in high-threat environments, allowing them to penetrate enemy defenses while reducing exposure to enemy fire. DEFIANT X’s X2 coaxial rotor system and pusher prop allows for a high degree of maneuverability in and around the objective which is also directly linked to survivability.

DEFIANT achievements include:

  • Greater than 60-degree banked turns.
  • Demonstrating mission-relevant cargo capacity by lifting a 5,300-pound/2,404-kg Guided Multiple Launch Rocket System external load.
  • Exceeding 245 knots/282 mph/454 km/h in level flight.
  • Demonstrated Level 1 low-speed agility with fly-by-wire controls.
  • Integration of U.S. Army test pilots into the Defiant program.
  • Based on the Collier Award-winning X2 Technology.
