The SB-1 Defiant is Boeing and Sikorsky's response to the US Army's requirement for a medium-lift utility helicopter under its Future Vertical Lift programme.
The SB-1 Defiant is a co-development programme between Sikorsky and Boeing, designed to inform the US Army's Future Vertical Lift programme.
21 марта 2019г. в США на заводском аэродроме Уэст-Палм-Бич в штате Флорида состоялся первый полет опытного компаундного вертолета SB-1 Defiant.
The SB>1 Defiant is the largest platform produced by Sikorsky to employ its X2 technology.
The SB>1 continues its flight test campaign. This shot provides a good view of the rear of the platform, showing its eight bladed 'pusher propeller' and twin-engine exhausts.
The FLRAA is the replacement for the UH-60 Black Hawk utility helicopter; likely competitors include those based on the Bell V-280 Valor tiltrotor (flying since 2017) and the Sikorsky Boeing SB-1 Defiant coaxial rotor compound helicopter.

A partnership between Boeing and Sikorsky is offering the SB>1 Defiant for the JMR technology and demonstrator programme.
Sikorsky, and its partner Boeing, are proving the scalability and tailoring of Sikorsky's X2 technology with the SB1 Defiant medium-class technology demonstrator. The SB1 is being developed for the US Army's Joint Multi-Role Technology Demonstration programme to help define the Future Vertical Lift (FVL) programme. Technologies used on GE’s FATE engine will be available if a new centre-line engine is required for FVL.
The Defiant X looks sleek, streamlined, stealthy and futuristic, especially when compared with current battlefield rotorcraft, which often look little different from their predecessors.
The Defiant X’s engine shrouds and reshaped trailing edges are noticeably different to the SB-1

The Sikorsky-Boeing team is developing assault and attack variants of the SB1 Defiant medium-lift helicopter for the US Army's Joint Multi-Role Technology Demonstration programme to help define the Future Vertical Lift programme. Technologies used on GE's FATE engine will be available if a new centre-line engine is required for FVL.
