The trials of the USNS John Glenn were conducted by the Navy's Board of Inspection and Survey and involved the testing of various hull, mechanical, and electrical systems to show the vessel met Navy standards.
The ship, built by General Dynamics National Steel and Shipbuilding Company, will be used to transfer vehicles, supplies, equipment and personnel from large Maritime Pre-Positioning Force ships to onshore locations using air cushion landing craft.
The vessel has 25,000 square feet of space for storage of vehicles, a vehicle transfer ramp and carries as many as three landing craft. It uses float-on/float-off technology, meaning it can partially submerge for transfer operations.
"Highly versatile non-combatant vessels like John Glenn make our large scale at-sea missions possible," said Capt. Henry Stevens, Strategic and Theater Sealift Program manager, Program Executive Office, Ships. "The ship's extensive vehicle and stowage space and remarkable transport capabilities will greatly facilitate operations across Geographic Combatant Commands, especially in areas where port access by larger ships is difficult or impossible."
The USNS John Glenn carries a crew of 34 civilian sailors and will be assigned to a maritime prepositioning ship squadron.
