The Sikorsky Raider X prototype helicopter for the US Army’s Future Attack Reconnaissance Aircraft (FARA) competition is “more than 85% complete,” the company has announced.

The project is also progressing 50% faster through production and assembly compared to legacy programmes and resulting in a cost-effective, transformational aircraft.

Sikorsky, a Lockheed Martin company, has made significant progress on Raider X, which is now weight on wheels at the Sikorsky Development Flight Center in West Palm Beach, Florida.

Raider X, which Sikorsky has begun powering on, has accomplished nearly 50% of required System Acceptance Test procedures.

X2 technology underpins the Raider X design. The compound coaxial technology of X2 provides growth margin for increased speed, combat radius and payload. This enables a broader range of aircraft configurations for specific mission requirements.

“Our transformational Raider X will deliver broad benefits to the Army including the lowest schedule risk and greatest technical maturity of the FARA competitors,” said Sikorsky president, Paul Lemmo. “With X2 Technology, RAIDER X has the ability to grow, unlike a single-main rotor configuration. We’re looking to the future and we are committed to helping the Army deter threats and defend freedoms well into the 21st century.”

In addition, the build of Sikorsky’s second FARA fuselage is now complete. This fuselage is being integrated into Sikorsky’s structural test programme and will be used to validate the flight and ground loads capability of the airframe. These tests support the Raider X CP flight safety programme and provide data to optimise and accelerate the design for the full weapons system.

“We took an innovative approach with our second CP fuselage,” said Sikorsky FARA chief engineer Pete Germanowski. “The second fuselage has not only increased the efficiency of the build and test of our first CP aircraft, it gives us the option to build it out as a second CP aircraft, providing us with more flexibility and greater risk reduction.”

Raider X features Modular Open System Architecture (MOSA)-based avionics and mission systems offering “plug-and-play” options for computing, sensors, survivability and weapons.

“The FARA mission requires operational flexibility, and Raider X provides that operational flexibility the Army needs including speed where it matters, a large multi-functional weapons bay and unprecedented acceleration and deceleration capability,” said Jay Macklin, Sikorsky business development director. “Raider X is the most agile, lethal and survivable aircraft, designed for vertical lift dominance against evolving threats of the future.”
