US Marines eye UK JSF shipborne technique
“A shipborne rolling vertical landing (SRVL) technique being developed by the UK for the Lockheed Martin F-35B is being eyed by the US Marine Corps as a way to facilitate operation of short take-off and vertical landing (STOVL) Joint Strike Fighters from US Navy aircraft carriers....
...For the USMC, the technique would allow a conventional approach to a short landing on the carrier and could ease integration of the F-35B with US Navy F/A-18E/Fs.
“We strongly support what the UK is doing on rolling landings,” says Lt Gen John Castellaw, USMC deputy commandant for aviation. Studies on how the F-35B will be operated continue, but SRVL “appears to be a viable option”, he says....
...“We continue to work with the navy on this,” Castellaw says, pointing out the STOVL Harrier has been operated successfully alongside US Navy fighters as part of an air wing the carrier USS Roosevelt.” [1976-7]
