PACIFIC OCEAN (April 28, 2015) The littoral combat ship USS Freedom (LCS 1) transits alongside the aircraft carrier USS John C. Stennis (CVN 74) in preparation for a replenishment-at-sea training exercise. U.S. Navy ships are underway conducting an independent deployer certification exercise off the coast of Southern California. The exercise provides a multi-ship environment to train and certify independent deployers in surface warfare, air defense, maritime-interception operations, command and control/information warfare, command, control, computers and combat systems intelligence and mine warfare.
