Aircraft program
Counter-rotating coaxial rotor attack helicopter with pusher propeller. Includes variants Sikorsky-Boeing SB>1 Defiant (demonstrator), Defiant X (Future Long Range Air Assault program, FLRAA contender - not chosen) and Raider X (contender for U.S. Army's Future Attack Reconnaissance Aircraft (FARA) program - chosen). Derived from X2 technology demonstrator.
The aircraft as engineered: what it is built from, the systems it flies with, and its configuration — each box a theme.
Technical reference compiled with AI research; a value appears only where two independent research passes and a web fact-check agree. Gaps are deliberate.
