CH-53K Integrated Test Team Stretches King Stallion’s Sea Legs

CH-53K Integrated Test Team Stretches King Stallion’s Sea Legs By Paul Lagasse A team of pilots and engineers from Air Test and Evaluation Squadron (HX) 21, based at Naval Air Station Patuxent River, Maryland, recently completed a crucial series of sea trials of the CH-53K King Stallion that not only provided them with valuable developmental test information about the aircraft, but could change the way the squadron conducts similar tests in the future.

A CH-53K King Stallion, assigned to Air The test team of 96 personnel embarked on USS Wasp (LHD 1) in early June to conduct an intensive series of tests that were to all spots, and was able to launch 13 sorties in the first eight days of ship-based maintenance.

Their true professionalism enabled all of our successes.”

“One of the things that stands out about this detachment was the quality of the ship’s crew from the leadership on down, their commitment to figuring out a way to make it work no matter what we needed,” Neubert said. “I think that reflects the command culture. The ship’s Commanding Officer, Capt. Greg Baker, likes to get to ‘Yes.’ Every department embodied that mentality.”

The envelope expansion testing that the team accomplished has resulted in the largest fleet envelope for any Navy and Marine Corps helicopter currently in existence, according to the squadron.

“I think this detachment is going to rewrite how we plan a test phase,” Foxton said. “It’s an opportunity for us to find very specific efficiencies in our testing, which will in turn increase our speed to the fleet.”

Neubert agreed.

“In flight test, we specialize in risk mitigation and preparing for how we will respond to something that goes wrong,” Neubert said. “What we discovered in this test is that in the future, we’ll want to spend more time planning how we will we respond if something goes unexpectedly great.

“Our objective is to provide the fleet Marines with a safer and more effective platform with greater operational capability, and this detachment was a successful example of that,” he said. “This is why we do flight test—because we come from the fleet, and we want to give good products back to the fleet.”
