Daniel Braun, left, Eric Sanchez and David Barney, Systems Center Pacific engineers at Space and Naval Warfare Systems Command, perform pre-deployment inspections on littoral battlespace sensing gliders aboard the Military Sealift Command oceanographic survey ship USNS Pathfinder. Each glider hosts a payload suite of sensors that will measure the physical characteristics of the water column as the glider routinely descends and ascends in the ocean. The gliders will be deployed during an at-sea test aboard Pathfinder Oct. 22 - Nov. 5.
