F-35 Ground Testing Shows Potential for F-35A Lifetime Extension
(Source: Lockheed Martin; issued Sept. 17, 2018)
FORT WORTH, Texas --- The F-35 Joint Program Office and Lockheed Martin have completed F-35 static, drop test, and durability testing and early results indicate a potential for an increased service life certification for the F-35A variant.

The rigorous testing supports validation of the airframe’s strength and resilience to perform in the demanding environments it will experience throughout its operational lifetime and the final results will support fleet management and maintenance forecasting for decades of operations.

“The transformational F-35 pushes the boundaries of engineering and physics with supersonic speed, agility, high attitude and angle of attack, weapons capacity, vertical landings, carrier operations and much more,” said Greg Ulmer, Lockheed Martin’s vice president and general manager of the F-35 program. “Durability testing gives the men and women who fly the F-35 great confidence in the aircraft’s performance today and for decades to come.”

Ground testing includes a full-scale durability airframe of all three variants, which were loaded in unique test rigs and laboratories to simulate ground and flight load conditions during fleet operations. The F-35 aircraft’s service lifetime is 8,000 hours, and each test airframe is required to complete two life-times of testing, or 16,000 hours. The F-35A vastly exceeded the requirement by completing three full life times of testing, or a simulated 24,000 hours, which gives the program confidence in a potential service-life increase.

“We look forward to analyzing the results and bringing forward the data to potentially extend the aircraft’s lifetime certification even further,” said Ulmer. “Already certified for one of the longest lifetimes of any fighter, an increase would greatly reduce future costs for all F-35 customers over several decades to come.”

The F-35A airframe completed its testing at BAE Systems in Brough, England and the F-35B and C variants were tested at Lockheed Martin in Fort Worth, Texas. All variants undergo final teardown inspections at the National Institute for Aviation Research in Wichita, Kansas.

With radar evading stealth technology, advanced sensors, enhanced weapons capacity, supersonic speed and superior range, the F-35 is the most lethal, survivable and connected fighter aircraft ever built. More than a fighter jet, the F-35’s ability to collect, analyze and share data is a powerful force multiplier enhancing all airborne, surface and ground-based assets in the battlespace and enabling men and women in uniform to execute their mission and come home safe.


Headquartered in Bethesda, Maryland, Lockheed Martin is a global security and aerospace company that employs approximately 100,000 people worldwide and is principally engaged in the research, design, development, manufacture, integration and sustainment of advanced technology systems, products and services. This year the company received three Edison Awards for ground-breaking innovations in autonomy, satellite technology and directed energy.
