Here’s Why the F-35 Lightning II Is Both A Great and Terrible Program: Q & A with Renowned F-35 Expert Abraham Abrams

Key Takeaways

• F-35 is the largest fighter production program in history
• Cost overruns and low availability strain US fighter fleets
• Block 4 upgrades delayed to early‑mid 2030s will boost capability
• Competing 4+ generation jets retain advantages in range, payload, maintenance
• Hypersonic and laser weapons being explored for future F‑35 integration

Pulse Analysis

The F‑35 Joint Strike Fighter remains the most ambitious weapons program ever launched, with more than 20 partner nations committing to its airframe. Its sheer scale has driven economies of scope, making it the default choice for many NATO and Indo‑Pacific allies. Yet the program’s financial discipline has been shaky: lifetime costs have ballooned well beyond original estimates, prompting the U.S. services to trim legacy fleets and curtail pilot flight hours. This paradox of strategic indispensability and fiscal strain forces defense planners to balance capability gains against budgetary realities.

Compared with fourth‑generation platforms such as the F‑16, F‑15EX, and Eurofighter Typhoon, the F‑35 offers unmatched sensor fusion, low observable design, and network‑centric warfare capabilities. However, its operational availability lags behind more maintenance‑friendly aircraft, and its range and payload are modest relative to heavyweight fighters. The long‑awaited Block 4 software and hardware upgrades, now slated for the early‑mid 2030s, promise to close many of these gaps by enhancing radar performance, electronic warfare suites, and weapons carriage. Until then, allies continue to field a mixed fleet, leveraging the F‑35’s niche strengths while relying on legacy jets for high‑tempo missions.

Looking ahead, the F‑35’s vast user base makes it an attractive testbed for emerging armaments. Lockheed Martin’s Mako Multi‑Mission Hypersonic Missile is already being sized for the internal bays of the A and C variants, and several partner nations are investigating compact solid‑state laser pods to counter swarms of low‑cost drones. Successful integration of these systems could extend the platform’s relevance well beyond its original service horizon, reinforcing U.S. and allied air superiority in contested regions such as the Indo‑Pacific and Eastern Europe.
