MARINE CORPS AIR STATION YUMA, Ariz.— An F-35B lightning II with Marine Fighter Attack Squadron (VMFA) 121 prepares to take off aboard Marine Corps Air Station Yuma, Ariz., Jan. 9, 2017, as it transits the Pacific en route to Marine Corps Air Station Iwakuni, Japan. VMFA-121 is the first operational F-35B squadron assigned to the Fleet Marine Force, with its relocation to 1st Marine Aircraft Wing at Iwakuni. The F-35B was developed to replace the Marine Corps’ F/A-18 Hornet, AV-8B Harrier and EA- 6B Prowler. The Short Take-off Vertical Landing (STOVL) aircraft is a true force multiplier. The unique combination of stealth, cutting-edge radar and sensor technology, and electronic warfare systems bring all of the access and lethality capabilities of a fifth-generation fighter, a modern bomber, and an adverse-weather, all-threat environment air support platform.
