Commander Strike Force Training Atlantic

Commander, Carrier Strike Group FOUR (CCSG-4 or COMSTRKGRUFOUR) is the U.S. Fleet Forces Command formation charged with training and certifying Atlantic Fleet Carrier Strike Groups, Amphibious Ready Groups, and independently deploying surface ships. Its mission is to "Conduct safe and effective Strike Force Training of the Atlantic Fleet."

From 2004 to 2014, The command was known as Commander, Strike Force Training Atlantic (CSFTL or COMSTRKFORTRALANT)

Until 2004, The command was known as Carrier Group FOUR/Commander, Carrier Striking Force (CCG-4).

CCSG-4 is a one star command under the three-star Deputy Commander, U.S. Fleet Forces Command, and is based at Naval Station Norfolk, Virginia. Tactical Training Group, Atlantic (TTGL) and Expeditionary Warfare Training Group, Atlantic (EWTGL) are subordinate commands.

Carrier Division Four was initially activated as an element of the United States Fifth Fleet on 13 March 1943. Seeing extensive action throughout the Second World War, Carrier Division Four was embarked in many of the most famous aircraft carriers in the Pacific Theater: USS Bunker Hill (CV-17), USS Intrepid (CV-11), USS Independence (CVL-22), USS Franklin (CV-13), USS Cabot (CVL-28), and USS Lake Champlain (CV-39). As a major participant in the Marshall Islands Campaign, the Battle of Leyte Gulf, and the Battle off Cape Engaño, planes under the direction of Carrier Division Four, aboard the USS Intrepid, sank Japanese aircraft carriers Zuiho, Zuikaku, and Chiyoda. Other notable victories include the sinking of the battleship Yamato and naval support during the Battle of Okinawa.

Following World War II, Carrier Division Four was transferred to the Atlantic Fleet. In October 1955, Carrier Division Four assumed administrative command of the world's first super-carrier, USS Forrestal (CVA 59). USS Saratoga (CVA-60) joined the Division in 1956, making Carrier Division Four the first task group composed solely of super-carriers. Subsequent operations laid the foundation for tactical employment of carriers well into the next decade.

Commander, Carrier Division Four boarded the USS Forrestal in July 1965 and deployed to the Mediterranean, where it transferred to the USS Franklin D Roosevelt and returned to Norfolk in December 1965. It did two or three additional Mediterranean Sea cruises on USS Independence and USS America before January 1969 (exact dates and sequence not known).

Carrier Division Four was re-designated Carrier Group Four in July 1973. It was responsible for facilitating the Navy's transition from traditional battle force tactics to the modern day battle group concept, emphasizing the Commander's responsibility for the whole battle group (destroyers, submarines, and auxiliaries) and not just the carrier and air wing.^{[citation needed]}
