PORT HUENEME, Calif. (Aug. 24, 2022) Royal Navy Cmdr. Derek Powles, left, watches as Ted Brooks with Maglogix Inc. and Petty Officer 2nd Class Josh Miller with the Navy's Surge Maintenance program run through a flooding simulation in which water hypothetically breaches an interior hatch during the Repair Technology Exercise, or REPTX, aboard the Self Defense Test Ship at Naval Surface Warfare Center, Port Hueneme Division (NSWC PHD). Miller uses two high-powered magnets, placed against the wall above and below the hatch, and slips in a metal unistrut to brace the door. (U.S. Navy photo by Dana Rene White)
