Even with faster medevac aircraft, uparmored ambulances, and more medical personnel at the front, will casualties get to life-saving care within the “golden hour”?

The Army wants a lot out of its Black Hawk replacement, at $43 million apiece — but the Marines and special operators want even more.

How can Army accelerate its Future Long-Range Assault Aircraft when one leading contender started flight tests just seven days ago?

The thing that delayed Defiant, it turns out, is the same thing that makes it really attractive to the Army.

“Now that they’ve completed the initial ground run, the team can finish its work to clear the aircraft for first flight,” said Mike Hirschberg, executive director of the Vertical Flight Society. “Assuming the Defiant team doesn’t find anything noteworthy from its ground testing, it should be up in the air in the next few weeks.”

While Bell’s rival V-280 uses tiltrotor technology, proven in widespread service on the V-22 Osprey since 2007, the Defiant uses Sikorsky’s revolutionary compound helicopter technology, which promises superior agility — but which has only actually flown in two experimental aircraft, the X2 and S-97 Raider, both of which are much smaller than Defiant.

Colin Clark climbs in and out of the V-280 at the Association of the US Army show, from cockpit to troop compartment, and gets a thorough briefing from Bell on what they’ve building, from engineering refined by a decade’s experience with the V-22 Osprey to sensor technology derived from the F-35 Joint Strike Fighter — except upgraded.

“It’s much more like a fighter aircraft than a helicopter,” Sikorsky’s test pilot tells me in the video as he maneuvers gleefully.
“Whoa, warn me next time!” I say after a particularly nifty/nauseating roll.

Sikorsky and Boeing are saying that their aircraft is taking longer than Bell’s because their design is more inventive — harder, riskier, and more time-consuming, yes, but ultimately better. In particular, while the SB>1 looks like it’ll be a little slower than the V-280, going by the companies’ projections for top speed, Sikorsky and Boeing say their machine will be much more maneuverable.

The Army doesn’t only want much faster aircraft: It wants them to cost the same to build, operate, and maintain as its current helicopters. Otherwise it can’t fit them into an unchanging aviation budget. That’s an awfully high bar.
