History
Established under the Department of Defense after 1947, the First Fleet remained operational until 1 February 1973, primarily in the western Pacific Ocean as part of the Pacific Fleet. In 1973, it was disestablished and its duties assumed by the United States Third Fleet.
Vice Admiral Alfred Montgomery was named as Commander, First Task Fleet, in an air station report of July 1947, with an inspection visit by a group of senior officers. The old cruiser Salt Lake City was sunk as an atomic bomb test target during First Task Fleet maneuvers in May 1948. USS Salisbury Sound became the flagship of Vice Admiral Gerald Bogan (Commander First Task Fleet) on 25 March 1949. USS Curtiss served as flagship for Commander First Fleet early in 1949 for three weeks of amphibious operations in Alaskan waters to evaluate cold weather equipment. USS Helena served as flagship for Commander, First Fleet, from January 1960 to March 1963. USS Providence served as flagship in San Diego from 1969 until April 1972, except for yard overhaul in 1970 when USS Chicago assumed the role.

Why this record matters
The phrase “fleet of United States Navy” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jun 19, 2026. The linked authority identifier is Q6140125. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1947, 1973, 1948 and 1949.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
