History (short)

Block Island got underway for Pearl Harbor on 20 March 1945. Upon arrival she underwent a period of provisioning and training in preparation for the invasion of Okinawa. On 17 April, Block Island left Hawaii and steamed toward Okinawa, via Ulithi. Flight operations commenced immediately upon her arrival 3 May and lasted until 16 June when she departed for Leyte. After a brief stay at San Pedro Bay, the carrier steamed through the Straits of Makassar for Borneo. From 26 June-6 July, she took part in the Balikpapan operation. She then proceeded to Guam where she was anchored at the time of the cessation of hostilities.
From 6–9 September, Block Island took part in the evacuation of Allied prisoners of war from Formosa. She continued cruising in the Far East until 14 October, and arrived at San Diego on 11 December 1945. Leaving San Diego on 6 January 1946, she transited the Panama Canal and reached Norfolk on the 20th. She was placed in service in reserve on 28 May 1946.
On 29 May 1946, Block Island was towed from Norfolk to Annapolis, reporting to the Superintendent of the Naval Academy to serve as a training ship for midshipmen. This duty was terminated on 3 October 1950, and Block Island was transferred to the Atlantic Reserve Fleet.
The vessel was recommissioned on 28 April 1951 and reported to the Atlantic Fleet. From June 1951-November 1953, she carried out local operations off the Virginia Capes, made four cruises to the Caribbean and one to the United Kingdom, France, and Italy from 17 April–26 June 1953.
On 15 January 1954, she was placed in commission in reserve at Philadelphia and out of commission in reserve on 27 August 1954. In 1957-1958, she was redesignated LPH-1 in anticipation of conversion to an amphibious assault ship, but the conversion was canceled and her designation reverted to CVE-106 before any work was done. Block Island was stricken from the Naval Vessel Register on 1 July 1959.
