No catapults; no ski ramp either. Photo shows forward vertical lift fan doors open at lift off. Same technique used by Harriers.
Basically, an amphibious ship(minus well deck) imitating an escort carrier. Wonder how long it would take to run through its aviation ordnance stores during full scale close air support operations? (Problem during “Harrier Carrier” ops in OIF.)
That’s still a rolling liftoff, right?
I can’t see the F-35B doing a full vertical takeoff with that ordinance load, and I don’t see the engine nozzle is in the vertical position.
