ATLANTIC OCEAN (May 20, 2015) A F-35 Bravo Lighting II prepares to land on the flight deck of the amphibious assault ship USS Wasp (LHD 1). Wasp, with VMFA-121 and VMFAT-501 embarked, is underway conducting the first phase of operational testing (OT-1) which will evaluate the full spectrum of F-35B measures of suitability and effectiveness in an at-sea environment. Data and lessons learned will lay the groundwork for F-35B deployments aboard U.S. Navy amphibious carriers following the Marine Corps' F-3B initial operating capability (IOC) declaration in July 2015.
