USS Blueback (SS-326), a Balao-class submarine, was the first submarine of the United States Navy to be named for a type of salmon, specifically, the Blueback salmon, also known as the sockeye salmon.
Her keel was laid down on 29 July 1943 by the Electric Boat Company of Groton, Connecticut. She was launched on 7 May 1944 sponsored by Mrs. William Brent Young, wife of Rear Admiral Young, and commissioned on 28 August 1944 with Lieutenant Commander M. K. Clementson in command.
Blueback arrived at Pearl Harbor on 21 November 1944. During the period from 16 December 1944 to 20 July 1945 she completed three war patrols in the South China Sea and Java Sea. She sank a 300-ton submarine chaser, as well as eight smaller vessels and inserted a Z Special Unit operative on the north coast of Java in Operation Binatang. She arrived at Subic Bay, Luzon, Philippines, from her third and last war patrol on 20 July 1945.
On 4 September 1945 Blueback arrived at Apra Harbor, Guam, where she remained until 28 November, conducting daily underway training exercises. After a voyage to the Caroline Islands and the Admiralty Islands, she returned to Guam on 15 December. She stood out for San Diego, California, on 12 January 1946. Remaining on the west coast until 26 August 1946, she then departed for a tour of the Far East. She visited Pearl Harbor, Truk, Subic Bay, Tsingtao and Shanghai, China, before returning to San Diego on 29 November. Blueback conducted one more cruise to Pearl Harbor from 17 February to 4 April 1947 and then carried out local operations and type training along the coast of California until March 1948.
The following is an excerpt from the decommissioning booklet of the 2nd USS Blueback, SS-581. The booklet was printed and distributed by the US Navy.
On 4 March 1948 Blueback departed the West Coast and proceeded to the Mediterranean Sea, via New London, Connecticut. She arrived at İzmir, Turkey, on 11 May 1948 and on 23 May 1948 was decommissioned and transferred to Turkey. She was renamed TCG İkinci Inönü (S331) ("Second Inonu"), the second of three submarines named by the Turkish Navy after the Second Battle of İnönü during the Turkish Independence War.
Other ships named İnönü:
- TCG 1. Inönü (S 330) was a submarine in the Turkish Navy.
- TCG 2. Inönü (S 333) was a submarine in the Turkish Navy.
