Rolls-Royce has been awarded a $215m (£133m) contract to produce and support its LiftSystems technology for the F-35 Lightning II program.
The technology gives F-35B aircraft the ability to perform short take-offs and vertical landings and is currently being used by the US Marine Corps in Yuma Arizona.
Rolls-Royce LiftSystem Program director said:
The innovative Rolls-Royce LiftSystem continues to demonstrate its effectiveness in field operation and in the recent F-35B shipboard trials on the USS Wasp. As we expand our field support, we remain focused on efficiency and further increasing the affordability of LiftSystems for the F-35B Lightning II.
Up to this point, Rolls-Royce has delivered 42 LiftSystems and has expanded field support to five locations where F-35B aircraft are being flown.
