British companies developed a new thermal metal coating for use on the flight deck of the UK Royal Navy's Queen Elizabeth Class (QEC) aircraft carriers.
The coating will protect the carriers' flight deck from the heat generated by the thrusters of the new F-35B Lightning II fighter jets.
Developed in partnership with Tyne and Wear-based Monitor Coatings, the protective coating is a combination of aluminium and titanium that can endure heat levels of up to 1,500°C (2,700°F).
