JACKSONVILLE, Fla. –
The first Royal Navy (RN) F-35 Lightning II aircraft arrived at Fleet Readiness Center Southeast (FRCSE) Dec. 3, 2025, for Production Asset Inspection Requirement Tier II (PAIR II) corrosion-mitigation inspections.
Using the PAIR II process, artisans on FRCSE’s F-35 corrosion speed line will inspect the aircraft’s underlying structure and remove and repair any corrosion to prevent further damage.
PAIR II is a comprehensive process that includes detailed corrosion mapping, structural assessments, and component repairs or replacements. To minimize aircraft downtime, FRCSE artisans optimized the PAIR II workflow, reducing the standard turnaround time from 180 days to approximately 60 days, significantly improving the availability of F-35 aircraft for operational service.
To further reduce future corrosion and repair costs, FRCSE is also sharing F-35 corrosion-prevention best practices with Royal Navy maintenance teams for use both ashore and at sea.
The 60 artisans and support staff on FRCSE’s F-35 team have undergone extensive training on the aircraft’s advanced systems, including the Autonomic Logistics Information System (ALIS) and specialized surface coatings.
“The FRCSE speed line is recognized within the F-35 community for efficient and cost-effective corrosion
mitigation,” said Capt. Mike Windom, FRCSE commanding officer. “We are proud to extend our expertise to support our Royal Navy allies, ensuring their F-35 aircraft maintain peak mission readiness.”
The F-35 is a fifth-generation fighter used by the Navy, Marine Corps, Air Force and 19 allied nations. Combining stealth, multi-mission capability, electronic warfare and advanced lethality, it plays a key role in global deterrence.
