A new mission control room opened its doors earlier this month, equipped so the Integrated Test Force will be able to monitor real-time performance of the aircraft during its test missions here beginning this fall.

The long-awaited aircraft, the first to be developed within the Defense Department to meet the needs of three services, promises state-of-the-art technology at a cost officials say simply couldn’t be matched by three separate aircraft programs.

“What’s unique about this aircraft is that we’re building three variants, all at once,” said Marc Trinklein, deputy director for the Integrated Test Force.

These variants are designed for the specific needs of the Air Force, Marine Corps and Navy, as well as international partners that are helping fund and develop the aircraft, he said. This represents the first time in military procurement history that the United States has partnered with another nation to build an aircraft from the ground up.

Current partners are the United Kingdom, Italy, the Netherlands, Turkey, Canada, Australia, Denmark and Norway, but Trinklein said more are expected to sign on.

This arrangement brings unprecedented economies of scale. The aircraft’s three models share many common designs, technologies and maintenance requirements, Trinklein said. For example, all three aircraft can use a common engine, one produced by two different contractors.

At the same time, he said, they’ll deliver revolutionary new capabilities adapted for close-air support, tactical bombing and air-to-air combat missions.

The bulk of the F-35s will be the “A” model, configured for the Air Force to replace F-16 Fighting Falcons and A-10 Thunderbolt IIs and complement the F-22A Raptor. They will feature conventional takeoff and landing capabilities.

This aircraft, which made its maiden flight at the Lockheed-Martin plant in Fort Worth, Texas, in mid-December, is expected to undergo developmental testing here and at Fort Worth beginning in mid-2009 or early 2010.

Meanwhile, developmental testing for the other two F-35 variants, the “B” and “C” models, will take place at Naval Air Station Patuxent River, Md.

The “B” model, being developed for the Marine Corps, will have short takeoff and vertical landing capabilities. It is designed to replace the Marines’ F/A-18C and D Hornet fighters and AV-8B Harrier IIs.

Initial plans called for the models to be developed sequentially, “A” followed by “B,” then by “C,” but Trinklein said the “B” model has moved to the front of the line. “The Marines have the greatest need due to the age of the Harrier fleet,” he said. “They are flying Harriers, and they are very old and not so capable, so they are recognized as the biggest need.” The F-35B is expected to make its first flight in May 2008.

The “C” model F-35 will be adapted for the Navy for carrier landings. It will feature larger, folding wings and stronger landing gear than the other variants and complement the F/A18 “E” and “F” models.
