About Submarine Group 7

Submarine Group 7 was established during the Korean Crisis in the 1950’s as Submarine Group Western Pacific, serving as squadron commander and administrative coordinators for submarines in the Western Pacific. In August 1961, the command’s name was changed to Submarine Flotilla 7. In June 1973, when the command was elevated to Task Force level subordinate to Commander, 7th Fleet, it assumed its present status as Commander, Submarine Force 7th Fleet/ Commander Task Force 74 reporting to U.S. 7th Fleet and Commander, Submarine Group 7 reporting to Commander Submarine Force, U.S. Pacific Fleet.

Submarine Group 7 was activated as Commander Task Force 157 (CTF 157) on October 15, 1992 to direct all submarine operations and mission tasking in the Central Command AOR, including the Red Sea and Arabian Gulf. On July 1, 1995, upon establishment of the U.S. 5th Fleet, CTF 157 was redesignated as CTF 54. On December 15, 2014, Commander, Submarine Squadron (CSS) 21 replaced the Commander, Task Force (CTF) 54 detachment as the organization charged with supporting submarines forward-deployed to the U.S. Naval Forces Central Command/U.S. 5th Fleet area of responsibility (AOR), which encompasses about 2.5 million square miles of water area including the Arabian Gulf, Red Sea, Gulf of Oman, Arabian Sea and parts of the Indian Ocean.
