F-22 receives publicly acknowledged RAM sustainment improvement

Last observed 2026-10-20 · Confidence 94%

Canonical event record

What happened

The first significant RAM-upgraded F-22 was delivered in 2014 through Lockheed Martin’s Inlet Coating Repair Speedline program.

Why it matters: The F-22’s stealth advantage depends on an industrial and maintenance system—not just a material formula—while its aging design limits future upgrades.
