F-35 Program Costs Surge to $1.7 Trillion Amid Delays and Inflation

A recent analysis by Warcosts.org places the total life-cycle cost of the F-35 Lightning II program at roughly $1.7 trillion, a dramatic increase from the $233 billion estimate made in 2001. The Department of Defense’s procurement budget has risen by about $51 billion, moving from $485 billion to $536 billion, as post-pandemic supply-chain disruptions and sustained inflation take their toll. The United States plans to field 2,470 jets across the three variants by 2044, with the Air Force receiving the bulk of the F-35A models, the Navy and Marine Corps sharing 413 F-35Cs, and the Marines operating around 280 F-35Bs.

Operational costs remain steep, with each flight hour costing roughly $42,000, and the fleet’s mission-capable rate remains below the 65-80 percent goal, prompting parts cannibalization. Delays in the Block 4 TR-3 upgrade, which adds significant computing power and cockpit improvements, halted deliveries for over a year, leaving about 100 aircraft idle at Lockheed Martin’s Fort Worth plant until the backlog was cleared in early 2026. Despite these challenges, the aircraft is expected to stay in service until 2088, potentially extending into the 22nd century.
