'Jet Killers': Why a tiny rust flake on the USS Abraham Lincoln flight deck is deadly

The Nimitz-class USS Abraham Lincoln features a massive 4.5-acre flight deck. Operating in severe maritime environments, the carrier is constantly exposed to saltwater and moisture. This harsh setting makes rust control a critical daily mission for the crew.

A tiny rust flake peeling from the carrier's structure transforms into a deadly weapon. This is known in naval aviation as Foreign Object Damage. Even a piece of debris weighing just two grammes can destroy an advanced aircraft engine.

Modern fighter jets like the F-35C Lightning II feature engines that act like giant vacuums. They can pull in massive volumes of air during takeoff. Any loose rust flake near the intake is instantly sucked into the delicate machinery.

Jet engine turbine blades rotate at incredible speeds during intense catapult launches. When a hard rust flake strikes these titanium blades at high velocity, it causes immediate structural fractures. The high-speed collision instantly shuts down the aircraft.

An engine destroyed by a tiny rust flake requires a complete overhaul or total replacement. Replacing a damaged F-35C turbofan engine can cost over $14 million. This also instantly removes a crucial combat asset from an ongoing mission.

The aircraft carrier operates in severe marine environments where saltwater and 100 per cent humidity constantly degrade metal. Managing this corrosion is a continuous operation. Maintenance teams must scrape and repaint steel structures constantly to prevent rust formation.

To prevent these catastrophic accidents, the crew performs mandatory walkdowns every day. Hundreds of sailors line up shoulder-to-shoulder to manually inspect the entire 4.5-acre deck. They physically search for and remove every single rust flake to ensure safety.
