The U.S. Air Force authorized extending the service life of the Lockheed Martin F-16’s designed service life to 12,000 Equivalent Flight Hours, far beyond the aircraft’s original design service life of 8,000 hours.
Following F-16 Service Life Extension Program (SLEP) structural modifications, the U.S. Air Force could safely operate Block 40-52 aircraft to 2048 and beyond. The Air Force and Lockheed Martin also reduced projected service life costs for the Block 40-52 fleet, paving the way for safe, cost-effective F-16 flight operations decades into the future.
“This accomplishment is the result of more than seven years of test, development, design, analysis and partnership between the U.S. Air Force and Lockheed Martin,” said Susan Ouzts, vice president of Lockheed Martin’s F-16 program. “Combined with F-16 avionics modernization programs like the F-16V, SLEP modifications demonstrate that the Fighting Falcon remains a highly capable and affordable 4th Generation option for the U.S. Air Force and international F-16 customers.”
Validation of the extended flight hour limit directly supports the SLEP goal of extending the service life of up to 300 F-16C/D Block 40-52 aircraft. SLEP and related avionics upgrades to the Air Force’s F-16C/D fleet can safely and effectively augment the current fighter force structure as U.S. and allied combat air fleets recapitalize with F-35 Lightning IIs.
A second phase, or Part II, of the F-16 SLEP airworthiness process continues with the request for Military Type Certificate (MTC), which will be submitted to the Air Force’s Technical Airworthiness Authority in the coming months. Part II seeks to validate further extending the F-16’s operational life based on final service life analysis from extended durability testing.
While the service had previously stated that up to 300 of the service's 1,017 Block 40/42 and 50/52 C- and D-model aircraft would see their airframe hours increased from the current 8,000 hours to 12,000 hours (an increase equivalent to about eight years of operational flying), a notice posted by the service on the Federal Business Opportunities (FedBizOpps) website on 12 June says that these numbers are now to grow to 841 aircraft and 13,856 hours.
