The U.S. Army’s Future Long-Range Assault Aircraft (FLRAA) program passed through the Army Requirements Oversight Council and received preliminary approval to set the capabilities development.

In replacing the UH-60 Blackhawk, the Army looks to modernize its aircrafts vertical lift capability. The idea is to complement the Army’s air assault mission and ability to move tactical level troops into and out of combat. 

Brigadier General Wally Rugen told Defense News that, “we really are focused on our air assault mission configuration and what that means for the number of troops that would need to be aboard and what requirements are needed to conduct that mission in darkness. Otherwise, the FLRAA program won’t have a ton of mandatory attributes in order to leave a lot of space for innovation as long as we achieve that air assault mission configuration.”

“[When] it comes to joint when it comes to fires when it comes to the tactical objective, the air movement — which is a bit more administrative in nature and not as intense on the combat scale — when we talk about air assault, we want transformational reach,” Rugen added. “That ability to exploit any penetration and disintegration that the Future Attack Reconnaissance Aircraft ecosystem, along with our joint partners has created.”

The two main competitors for the FLRAA are the Bell V-280 Valor tilt-rotor aircraft and the combination of Sikorsky and Boeing with their SB-1 Defiant coaxial helicopter. Each entry will submit proposals within the first half of next year with eyes toward a contract award in fiscal 2022 for the winning prototype. Prototypes would be delivered in early-to-mid 2026, with production beginning in 2028 and the new aircraft being fielded in 2030.

The Sikorsky-Boeing SB-1 Defiant is a compound helicopter with rigid coaxial rotors. It is powered by two Honeywell T55s, and a pusher propeller in the rear of the aircraft. These give it a 115 mph speed advantage (100 knots) over the conventional helicopters it aims to replace. 

Sikorsky is planning on replacing the T55 engines, which power the Chinook helicopters, with the Future Affordable Turbine Engine (FATE) to meet the radius requirement of  264 miles, (424 km). The crew compartment is 50 percent larger than the current Blackhawk helicopters. Recently in a test flight, the aircraft hit a speed of 205 knots, with a planned top speed of 230 knots which is the requirement and even up to 250 knots according to the company. 

“Exceeding 200 knots is significant also because it’s beyond any conventional helicopter speed, and we understand that speed and low-level maneuverability is critical to the holistic survivability in a future FVL environment,” Jay Macklin, Sikorsky’s Director of Future Vertical Lift Business Development said back in June.
