F-35 stealth fighter deliveries have been falling farther and farther behind, watchdog finds

A new Government Accountability Office (GAO) report highlights significant and worsening delivery delays for Lockheed Martin's F-35 fighter jets, with every F-35 delivered in 2024 averaging 238 days late, a substantial increase from 61 days in 2023. These delays are primarily due to the Technology Refresh 3 (TR-3) upgrade, which is now $6 billion over budget and five years behind schedule, contributing to the F-35 program's projected lifetime cost surging to over $2 trillion. Despite these persistent cost overruns and readiness challenges, the Pentagon plans extensive purchases and allies continue placing orders, signaling ongoing investment in the program.

Analysis

Lockheed Martin's (LMT) flagship F-35 program is experiencing severe and escalating operational difficulties, according to a new Government Accountability Office (GAO) report. Delivery delays have worsened significantly, with the average late delivery increasing from 61 days in 2023 to a substantial 238 days in 2024, a period where every aircraft was delivered behind schedule. The root cause is attributed to the Technology Refresh 3 (TR-3) upgrade, which is now reportedly $6 billion over budget and at least five years delayed. This operational failure is compounded by a program lifetime cost estimate that has swelled to over $2 trillion and a fleet mission-capable rate of just over 50%, highlighting persistent readiness and reliability challenges. Despite these negative fundamentals and a contract structure that allowed incentive payments for late deliveries, Lockheed Martin maintains an ambitious delivery guidance of 170 to 190 aircraft for the current year. This creates a significant disconnect between the company's outlook and third-party government assessments. However, the program's strategic importance is underscored by the Pentagon's unwavering commitment to purchase approximately 2,500 jets and continued orders from international allies, providing a resilient long-term demand floor that counterbalances the immediate execution risks.

Key Decisions for Investors

• Investors should view Lockheed Martin's forward guidance for F-35 deliveries with significant caution, as the 238-day average delay reported by the GAO suggests a high probability of the company missing its 2024 targets, which could trigger negative earnings revisions and stock price volatility.
• Despite the strongly negative sentiment and clear execution issues, the program's long-term revenue stream appears secure due to sustained Pentagon and allied demand, suggesting long-horizon investors might consider the current challenges a point of weakness for strategic positioning rather than a reason to exit.
• Monitor for any potential contract restructuring or changes in payment terms from the Department of Defense, as the GAO's critical report on cost overruns and ineffective incentives could lead to increased regulatory pressure and margin compression for the F-35 program.
