F-35 Lightning II remains key to US Air Force modernization despite challenges

The F-35 is used for various missions, including air dominance, ground strikes, and acting as a node in joint operations. Its ability to share data across different military domains makes it a force multiplier, supporting both new and older platforms in complex missions.

However, the program faces challenges. In fiscal year 2024, only 51.5% of the Air Force’s F-35A fleet was mission-capable, reflecting issues with spare parts, maintenance systems, and logistics. Critics have pointed to the aircraft’s complexity and cost, though Lockheed Martin reports a 40% reduction in its share of operating costs in recent years.

The F-35 is also significant for U.S. alliances. It is operated by multiple allied nations, which enhances joint operations and standardizes equipment and doctrine. Senior Air Force leaders have called the F-35 the “cornerstone” of the service’s tactical aircraft fleet. The program supports over 250,000 jobs in the U.S. and contributes billions of dollars to the economy through its supply chain.

Looking ahead, the F-35 will continue to evolve with upgrades such as the Block 4/Technology Refresh, which will improve sensors, radar, networking, and weapon integration. These updates are intended to keep the aircraft effective as global threats change.

“The challenges, such as high cost, readiness issues, and complex sustainment, are undeniable. But they also drive modernization and accountability, pushing the Air Force to innovate beyond the aircraft itself. If American airpower is to remain number one in the 21st century, the F-35 isn’t just part of that future - it is the foundation on which it is built.”
