Fleet Forces Command formation charged with training and certifying Pacific Fleet Carrier Strike Group s , Amphibious Ready Groups , and independently deploying surface ships . Overview . Commander , Strike Force Training Pacific ( CSFTP ) is a 1 - star command under Commander Third Fleet ( COMTHIRDFLT ) and is based at Naval Air Station North Island in San Diego , California . Tactical Training Group Pacific and Expeditionary Warfare Training Group Pacific are subordinate commands . CSFTP ' s mission : Through integrated training , mentorship and assessment at sea , Strike Force Training Pacific provides Fleet Commanders agile combat ready maritime forces armed with worldwide deployable skill sets in order to support global operations . Mission . ” The command was previously known as Commander , Carrier Group ONE ( CCG - 1 ) . History . CSFTP began as Commander , Carrier Division One ( ComCarDiv 1 ) . Commander , Carrier Division One ( ComCarDiv 1 ) was the first aircraft carrier formation in the United States when it was organized in October 1930 as part of the Aircraft Scouting Force , U . S . Fleet , operating in the Atlantic Ocean . In 1939 , Carrier Division One was transferred to the Pacific Scouting Force . Aircraft carriers assigned to ComCarDiv 1 saw service in World War II , the Korean War , and the Vietnam War . In late February 1946 " Midway " became flagship for Carrier Division 1 , operating in the Atlantic where she commenced flight training exercises in earnest . Arriving Yokosuka on 1 June 1957 , USS " Lexington " embarked Rear Admiral H . D . Riley , Commander Carrier Division 1 , and sailed as his flagship until returning San Diego on 17 October . In June 1973 , Commander , Carrier Division One was redesignated Commander , Carrier Group One ( ComCarGru 1 ) , and ComCarGru 1 took command of the carrier battle group during its change of homeport to Yokosuka , Japan , on 5 October 1973 , marking the first forward basing of a complete carrier task group overseas . In 1985 , Commander Carrier Group One aboard " Constellation " led Battle Group Delta to the Western Pacific and Indian Ocean , including USS " Crommelin " . In December 1990 , following commanding Battle Group Delta , ComCarGru 1 was designated Commander , Training Battle Group , with responsibility for the Carrier Battle Group Inter - Deployment Training Cycle ( IDTC ) within the U . S . Pacific Fleet . In 2004 , it became Carrier Strike Group 1 , and in 2005 it was redesignated Commander , Strike Force Training Pacific . One reported date for the change of designation was October 7 , 2005 , but this does not agree with a February 2005 change of command ceremony in which the formation was already being referred to as Commander , Strike Force Training Pacific . Major training exercises . CSFTP trains carrier strike group s primarily during Composite Training Exercises ( COMPTUEX ) and Joint Training Force Exercises ( JTFEX ) off the California coast . CSFTP also trains Amphibious Ready Group s ( ARG ) with their embarked Marine Expeditionary Unit s ( MEU ) , as well as other surface combatants not associated with a CSG or ARG . Composite Training Exercises ( COMPTUEXs ) are designed to integrate all warfare areas of the CSG or ARG / MEU . JTFEXs provides the Strike Group with realistic training in joint operations prior to deployment . The exercise requires integration of the CSG ’ s existing warfighting ability with other Joint and Combined assets to support warfare under a challenging threat scenario . Upon successful completion , CSFTP recommends deployment certification to Commander , Third Fleet . In addition , Fleet Synthetic Training ( FST ) is used throughout the training cycle to prepare units to go to sea . Synthetic training utilizes simulators and role players , and prepares units to go to sea at considerable savings in fuel , material , etc .
