Defense.gov News Article: Panetta Lifts F-35 Fighter Variant Probation

In a move that surprised no one, SecDef Leon Panetta has lifted the probation for the F-35B variant:
Defense Secretary Leon Panetta has ushered the F-35B out of the penalty box, after the short-takeoff-and-vertical-landing (Stovl) version of the stealthy fighter was sidelined for poor performance for more than a year by prior Defense Secretary Robert Gates.

Standing in a hangar in front of BF-4, one of two F-35Bs to conduct testing on the USS Wasp amphibious ship last fall, Panetta spoke to a small audience of government and industry workers on the Joint Strike Fighter test team.

“We now believe that because of your work the Stovl variant is demonstrating the kind of performance and maturity that is in line with the other two variants of JSF,” Panetta said here Jan. 20. “The Stovl variant has made — I believe and all of us believe — sufficient progress so that as of today I am lifting the Stovl probation.”


George Little, Panetta’s spokesman, said the secretary’s decision to lift the probation was underpinned by improvements in five key areas: structural shortcomings in the Stovl bulkhead, flutter in the auxiliary inlet door, problems in the lift-fan clutch, unexpected wear and tear on the drive shaft, and heating on the roll-post actuator.
The writer also notes that, "Thus far, the F-35B has been flown to Mach 1.4," which must have been before one of the "A" model test articles flew to Mach 1.6, and suffered significant damage, and the entire fleet was prohibited from supersonic flight.

The fact is that the real reason for the probation, and the one that Panetta and the Pentagon have neglected to mention, is that the F-35C is still significantly over weight, and for an STOVL aircraft, that doesn't just mean a few percent drop in performance, it means that it cannot perform its allotted missions, because it cannot make a vertical landing.

This was why the British, before switching to the catapult launched and arrested recovery F-35C, were looking at a Shipborne Rolling Vertical Landing at about 100 km/h forward speed.  They were afraid that the lack of performance would require aircraft to jettison (multimillion dollar) munitions before landing.

Those problems are still there

Panetta Lifts F-35 Fighter Variant Probation

NAVAL AIR STATION PATUXENT RIVER, Md., Jan. 20, 2012 – Defense Secretary Leon E. Panetta announced today he’s lifted probation from the Short Takeoff, Vertical Landing variant of the fifth generation F-35 Lightning II joint strike fighter which is absolutely vital to maintaining air superiority.

Defense Secretary Leon E. Panetta and U.S. Rep. Steny H. Hoyer of Maryland look at the cockpit of the F-35 Joint Strike Fighter with Navy Capt. Erik "Rock" Etz on Naval Air Station Patuxent River, Md., Jan. 20, 2012. Panetta and Hoyer toured several facilities related to the F-35 Joint Strike Fighter, which is in its test phases at the base.

Speaking during a town hall-style meeting here, the defense secretary discussed the latest development in the progress of the joint strike fighter program as service members, politicians and the civilian workforce listened.

“Early in 2011 DOD was compelled to put [the Short Takeoff and Vertical Landing] … on probation,” he said.

“Over the course of last year, you here at Pax River helped make an incredible difference by completing tremendous amounts of STOVL testing,” Panetta noted. “You demonstrated that we've made real progress towards fixing some of the known problems that we had with STOVL.”

Panetta lauded the joint strike fighter’s workforce at NAS Patuxent River for their efforts to bring the STOVL variant up to the standards of the two other existing versions of the F-35, the Conventional Takeoff and Landing and Carrier Variant.

“We now believe that because of your work, that the STOVL variant is demonstrating the kind of performance and maturity that is in line with the other two variants of the JSF,” Panetta said.

“As a result of your hard work and the hard work of JSF's government and industry team … the STOVL variant has made, I believe and all of us believe, sufficient progress so that as of today, I am lifting the STOVL probation,” he announced.

Panetta commended the crowd for their hard work, but cautioned that the JSF program still has more work to do. “We've got a long way to go with the JSF testing, and it's obviously not out of the woods yet,” he said.

“But I am confident that if we continue to do the hard work necessary … that both the Carrier and the STOVL Variant are going to be ready for operations and are going to be ready for doing the work that they have to do, which is to help protect this country,” Panetta said.

“I want you all to know that as secretary of defense, my department is committed to the development of the F-35,” he said. “It's absolutely critical … that we get it right. And that's why you're here. The developmental testing that's going on here will ensure that we get this right.”

Marine Corps Commandant Gen. James F. Amos called Panetta’s decision to lift the probation of the F-35B “hard-earned.”

“Secretary Panetta’s decision to take the F-35B Lightning II Short Takeoff, Vertical Landing variant off probation was a hard-earned and rewarding announcement for the entire DOD/industry team that worked very hard last year,” he said.

“Successful F-35B performance ashore and at sea has very positively advanced the state of demonstrated capability in 2011,” Amos said. “The positive momentum generated during 2011 will continue as testing proceeds, production aircraft are delivered, and fleet training begins in 2012.”

Panetta said it is important that the U.S. military maintains its technological edge into the future.
“That's where we have to be,” he said. “We're going to have a strong defense; we have got to be there.”

Panetta praised the capabilities of Patuxent’s workforce.

“Because of you, because of the very unique testing and capabilities that are offered here, we are able to maintain that technological edge,” Panetta said. “And I want to thank you again for your dedication, for your commitment, for your great skills.”

Panetta lauded the Patuxent River installation calling it “a very unique facility” and “a national treasure” that is important to maintain.

“These are world-class facilities … that [are] important to our military, important to our men and women in uniform who have to put their lives on the line, and it's important to our national security,” Panetta said.

“Please accept my deepest thanks for your work and dedication,” he said. “I couldn't do it without you.”
