A BatDiv or BATDIV was a standard U.S. Navy abbreviation or acronym for "battleship division." The Commander of a Battleship Division was known, in official Navy communications, as COMBATDIV (followed by a number), such as COMBATDIV ONE.
Pre-Second World War battleship divisions
Before the Second World War, the U.S. Navy battleship force was organized into five Battleship Divisions of three battleships each. Only two of these BATDIVs were composed of three battleships of the same class, but mixing battleships of separate two-ship classes to form three-ship BATDIVs was facilitated by the "Standard type battleship" concept of the US Navy, a design concept developed before 1922 calling for uniform top speed of 21 knots (39 km/h) and a tight tactical radius of 700 yards (640 m) for all battleships of the Nevada, Pennsylvania, New Mexico, Tennessee and Colorado classes.
Stationed at Pearl Harbor as part of the U.S. Pacific Fleet were three battleship divisions: Pennsylvania and Arizona with Nevada (BatDiv 1); Tennessee and California with Oklahoma (BatDiv2); and Colorado, Maryland and West Virginia (BatDiv 4). These nine battleships were intended to counterbalance the ten battleships of the Imperial Japanese Navy. At the time of the Pearl Harbor Attack, Pennsylvania was in dry dock and Colorado was being refitted at Bremerton Navy Yard, Washington State. Arizona was mated with Nevada and Oklahoma at that time.
The US Atlantic Fleet had a BATDIV (BatDiv 3) composed of New Mexico, Mississippi and Idaho and a training division (BatDiv 5) made up of the older battleships New York and Texas with Arkansas. BatDiv3 had been part of the Pacific Fleet until 20 May 1941 when its three ships were transferred to the Atlantc Fleet for Neutrality Patrol duty.
Battleship Division 1 was active in the Pacific at least until 1946, according to U.S. Navy records with the National Archives and Records Administration. On June 7, 1954, under the direction of Battleship Division 2, Norfolk, Virginia, the four battleships of the Iowa class operated together for the only time.
On January 15, 1957, Wisconsin reported to Commander Fleet Training Group, Guantanano Bay, Cuba and Rear Admiral Henry Crommelin, Commander Battleship Division Two broke his flag in Wisconsin. On May 27, 1957 Rear Admiral Lewis S. Parks relieved Rear Admiral Crommelin as Commander Battleship Division Two.
