Sikorsky's earliest attempt at a fast compound helicopter with stiff coaxial rotors was the Sikorsky S-69 (XH-59A) flown in the 1970s. Its top speed was over 260 knots but its excessive fuel consumption, vibration and complexity requiring the full-time attention of two pilots led to the program's cancellation. [5]

The SB-1 Defiant. The SB-1 Defiant (or "SB>1") is the Sikorsky Aircraft and Boeing entry for the program. It is a compound helicopter with rigid coaxial rotors and two Honeywell T55 engines. Its first flight took place in March 2019.
Sikorsky developed the X2 helicopter on a $50 million budget. The design includes expertise gathered from several earlier design projects. The S-69/XH-59A Advancing Blade Concept Demonstrator had shown that high speed was possible with a coaxial helicopter with auxiliary propulsion supplied using two jet engines, but that vibration and fuel consumption was excessive; [2] [3] [4] the Cypher UAV ...
