Mechanical fixes kept the SB>1 compound helicopter grounded for weeks this summer, but Sikorsky insists they can catch up.

Whatever their aircraft is like, Boeing’s PR strategy is definitely stealthy. There’s a strategic reason for that.

Sikorsky says their Future Attack Reconnaissance Aircraft design will fly faster, with bigger weapons, than archrival Bell’s. Bell says theirs will be cheaper and more reliable.

An IDF team has been taking test flights aboard Lockheed Martin’s new CH-53K in Maryland, but Boeing’s CH-47 Chinook is in the running too — and both programs could use a boost against their American critics.

“We’re back on the contract schedule,” Sikorsky program director Greg Hames told reporters visiting the company’s test site.

Flying sideways, backwards, in pirouettes, and in a markedly quiet stealth mode, the hybrid helicopter-turboprop demonstrated the maneuverability the Army considers essential to survive high-tech future battles with Russia or China.

The company is confident that there is no inherent flaw in the design. Instead, they say, there was a software error that would have hamstrung any aircraft — and that error won’t happen again.

Dan Schultz, Sikorsky president, calls the CH-53K heavy-lift helicopter an “optimally piloted” aircraft that allows ease of flying even in hellish weather conditions.

Critics have argued the tiltrotor aircraft could never be as nimble at low speed and low altitude as a helicopter. Bell says it’s proven them wrong.

Awards for Future Attack Reconnaissance Aircraft designs went to Bell, Boeing, Karem, Sikorsky, and a partnership of AVX and L-3.
