Task Force Alfa antisubmarine experiment and had as flagship for a time. Cornelius S. Snodgrass served as chief of staff for CRUDESFLOT 4 before his retirement in 1974. Cruiser-Destroyer Flotilla Six in the Atlantic (flagship at one point and included Yellowstone). Cruiser-Destroyer Flotilla Six included Destroyer Squadron Four with in 1971, seemingly home-ported at the Charleston Naval Base. Cruiser-Destroyer Flotilla Seven was homeported at San Diego, commanded by Admiral Waldemar F. A. Wendt from April 1962, with concurrent duty as Commander, Cruiser-Destroyer Force, Pacific, October–November 1961. CRUDESFLOT SEVEN was also commanded at one point by then Rear Admiral Elmo Zumwalt. In December 1969, Admiral Robert S. Salzer assumed command of Cruiser Destroyer Flotilla 3. Salzar assumed command of Cruiser Destroyer Flotilla 7 in September 1970, and after the disestablishment of that formation on 16 March 1971 returned to command of Cruiser Destroyer Flotilla 3. Other flotillas included Cruiser-Destroyer Flotilla Eight in the Atlantic, which at one point included Destroyer Squadron Twenty-Two, Cruiser-Destroyer Flotilla Nine in the Pacific, Cruiser-Destroyer Flotilla Eleven in the Pacific (with DesDiv 152, DesRon 15?), and Cruiser-Destroyer Flotillas Ten and Twelve in the Atlantic. On 30 June 1973 Cruiser-Destroyer Flotillas were redesignated Cruiser-Destroyer Groups (CRUDESGRUs). The overall responsibility for surface warships on the west coast of the US is taken by the Commander, Naval Surface Forces Pacific (COMNAVSURFPAC); on the east coast, the same responsibility rests with the Commander, Naval Surface Forces Atlantic (COMSURFLANT). Previously under this system, when deployed, a Cruiser-Destroyer Group Commander would normally have been assigned to command a Carrier Battle Group (CVBG). Cruiser-Destroyer Groups were superseded by Carrier strike groups from 1 October 2004. When a destroyer squadron deploys, for instance as part of a carrier strike group, overall command is transferred to the Naval Component Commander of the local Regional Command (e.g. COMNAVCENT or Commander US Naval Forces, Central Command).
