A Sailor performs a fresh water rinse after a countermeasure washdown test on the flight deck aboard the Nimitz-class aircraft carrier USS Dwight D. Eisenhower (CVN 69). Eisenhower and embarked Carrier Air Wing (CVW) 7 are on a regularly scheduled deployment in support of Maritime Security Operations (MSO). MSO help set the conditions for security and stability in the maritime environment, as well as complement the counter-terrorism and security efforts of regional nations. These operations deny international terrorists use of the maritime environment as a venue for attack or as a transport for personnel, weapons or other material.
