World War II service

Seaplane tender operations

Following her shakedown cruise, Biscayne joined the Atlantic Fleet and operated out of Boston, Massachusetts, on patrol and plane guard missions from 7 December 1941 until 27 May 1942. For the next four months she served as a seaplane tender and communications ship in Newfoundland and Greenland waters. Biscayne departed Norfolk, Virginia, on 17 October 1942 and, after a short stop at Guantanamo Bay, Cuba, moved to Freetown, Sierra Leone, with Patrol Squadron 92 (VP-92), arriving on 2 November 1942.

Biscayne moved to Casablanca, French Morocco, on 18 November 1942 and remained there until 25 April 1943 supporting patrol squadrons.

Amphibious force flagship operations in the Mediterranean

Biscayne arrived at Mers-el-Kebir, Algeria, on 26 April 1943 and became the flagship of Rear Admiral Richard Lansing Conolly, Commander, Landing Craft and Bases, Northwest African Waters. While at Mers-el-Kebir she was fitted out as an amphibious force flagship by repair ship USS Delta (AR-9) between 2 and 31 May 1943, although she retained her seaplane tender classification and AVP-11 designation for the time being. In May 1943, Biscayne shifted her moorings to Bizerte, Tunisia.

Departing Bizerte on 10 July 1943, Biscayne served as flagship of the Joss (Licata) Force in Operation Husky, the Allied invasion of Sicily. She remained off Sicily until 22 July 1943 and then returned to Bizerte.

Beginning on 9 September 1943, Biscayne took part in Operation Avalanche, the Allied landings at Salerno, Italy, as flagship for Vice Admiral H. Kent Hewitt and Rear Admiral Conolly. While off Salerno, she escaped unscathed from frequent air and gunfire attacks. On 12 September 1943, she sent a fire and rescue team on board the British ammunition ship Lyminge and saved that vessel and her cargo of ammunition from destruction. Biscayne also served as a temporary hospital ship while off Salerno. Biscayne retired to Bizerte on 11 October 1943.

On 7 November 1943, Biscayne became the flagship of Rear Admiral F. J. Lowry, Commander, 8th Amphibious Force. Sailing for Italy once again, she served as flagship during Operation Shingle, the Allied landings at Anzio, from 22 January 1944 to 2 February 1944.

Biscayne took part in the invasion of Iwo Jima from 19 February 1945 to 4 March 1945 as flagship of the transport screen. she carried out similar duties during Operation Iceberg, the landings on Kerama Retto on 26 March 1945 and on Okinawa on 1 April 1945. She remained off Okinawa, supporting U.S. operations during and after the Okinawa campaign, until 1 July 1945, during which time she served as flagship for the occupation of Iheya and Aguni Islands between 3 June 1945 and 9 June 1945.

After her tour at Okinawa, Biscayne retired to Leyte in the Philippine Islands, and remained in the Philippines through the end of World War II, which concluded with the cessation of hostilities with Japan on 15 August 1945.


Biscayne received six battle stars for her World War II service.

Biscayne departed the Philippines on 8 September 1945 to support the occupation of Korea. She remained on occupation duty in Korean and Chinese waters until 30 October 1945, when she left for the United States. Biscayne arrived at San Diego, California, on 21 December 1945 and at Portland, Maine, on 7 January 1946. She then moved to the United States Naval Academy at Annapolis, Maryland, for use as quarters for the academy's aviation instruction staff.
