EGLIN AIR FORCE BASE, Florida (REUTERS) - US Defence Secretary Chuck Hagel told military fliers on Thursday that the stealthy F-35 attack plane had "issues" but was still "the future for our fighter aircraft" despite a fire that grounded the fleet and jeopardised its international debut in Britain.
In a visit to the Florida base where the blaze occurred in late June, Hagel spoke with F-35 pilots and maintenance workers about the Lockheed Martin aircraft but was not able to say whether the planes would be cleared to resume flight in time to participate in air shows in Britain. Key F-35 contractors are Lockheed Martin Corp, Northrop Grumman Corp and BAE Systems Plc.
Hagel, speaking in front of a pair of the F-35s, said the pilots and maintainers voiced "tremendous confidence" in the so-called fifth-generation aircraft, which has stealthy radar-evading technology and a suite of integrated sensors that digest and feed information to the pilot through a special helmet.
"Some of the pilots told me it was the best aircraft that they had ever flown and some said it was the easiest and simplest aircraft they'd ever flown," Hagel said. "I was particularly happy to hear that because I believe this aircraft is the future for our fighter aircraft for our services," he said. "This is as big a project, the F-35, as we have at the Department of Defence and we've got a lot riding on this aircraft."
Hagel said he knew "there are issues" with the plane but he had "strong, strong confidence in the people who make this aircraft fly (and) maintain it."
The F-35 is the world's largest arms program and is currently projected to cost about US$398.6 billion (S$495 billion). The plane, which will ultimately replace most of the US military's fighters, has been sharply criticised over its huge cost growth. The plane had been scheduled to make its international debut at two air shows in Britain beginning this week - the Royal International Air Tattoo and Farnborough International Airshow.
But the military last week grounded the entire fleet of 97 aircraft in the aftermath of a fire at Eglin in late June in which a Pratt & Whitney engine on an Air Force variant of the plane broke apart and caught fire during takeoff. Pratt & Whitney is a unit of United Technologies Corp.
Eglin is one of the main bases where F-35 pilots and maintainers are being trained. Officials said there were 49 F-35s at the base, including all three variants of the plane.
Lockheed Martin Corp, Northrop Grumman and BAE on Thursday said they would invest up to US$170 million over the next two years to cut the cost of each of the new warplanes to under US$80 million each by 2019.
