Lance Cpl. Juan Olguin, from Lakewood, Calif., sprays the surface of an F/A-18C Hornet assigned to the Death Rattlers of Marine Fighter Attack Squadron (VMFA) 323 aboard the aircraft carrier USS Ronald Reagan during a countermeasure wash down on the flight deck. Sailors scrubbed the external surfaces on the flight deck and island superstructure to remove potential radiation contamination. Ronald Reagan is operating off the coast of Japan providing humanitarian assistance as directed in support of Operation Tomodachi.
