USS Hammerhead (SS-364)

USS ''Hammerhead'' (SS-364), a ''Gato''-class submarine, was the first ship of the United States Navy to be named for the hammerhead shark, a shark found in warm seas with a flattened anterior forward of the gill slits, presenting a hammer-like silhouette when viewed from above.

Construction and commissioning

''Hammerhead'' initially was ordered as a unit of the ''Balao'' class, but her builder, the Manitowoc Shipbuilding Company, did not receive the drawings for the ''Balao'' class from the Electric Boat Company in time to build ''Hammerhead'' or the submarines , , and to the new design, so they were built as ''Gato''-class submarines. Thus, in some references, these four submarines are listed as units of the ''Balao''-class.

''Hammerhead'' was launched on 24 October 1943 by the Manitowoc Shipbuilding Company at Manitowoc, Wisconsin, sponsored by Mrs. R. W Berry, and commissioned on 1 March 1944.

Operational history

After a month's training in Lake Michigan, ''Hammerhead'' was placed in a floating drydock and towed down the Mississippi River to New Orleans, Louisiana, where she arrived on 8 April 1944. She subsequently proceeded to Balboa, Panama Canal Zone, for further training, and thence to Pearl Harbor, Hawaii.

First patrol, June – August 1944

The submarine departed Pearl Harbor on her first war patrol 6 June 1944 in company with and . Cruising the seas south of Formosa, her first engagement came 9 June when she sank a sampan with gunfire. She then encountered a coastal oiler 29 June and closed for the attack, but the torpedoes failed to strike home and a surprise aerial attack forced the sub down. At the Next day, ''Hammerhead'' damaged several ships of a convoy. She made port at Fremantle, Australia 17 August 1944.

Second patrol, September – November 1944

''Hammerheads second war patrol was conducted in the Java and South China Seas. She departed Fremantle 9 September and made her first attack the night of 1 October, when a convoy consisting of four cargo ships, one oiler, and three escorts was detected off Borneo. ''Hammerhead'' fired 10 torpedoes, scored a total of 6 hits, and sent 3 of the cargo ships to the bottom (''Hiyori Maru'', ''Higane Maru'', ''Kokusei Maru'').

The morning of 20 October the submarine found still another six ship convoy, and after evading one of the escorts delivered a six-torpedo attack. Two more cargo ships fell victim to ''Hammerheads marksmanship. The submarine returned from this highly successful patrol 2 November 1944, and was later awarded the Navy Unit Commendation for her outstanding performance.

Third and fourth patrols, November 1944 – March 1945

The submarine commenced her third war patrol 25 November, returning to the South China Sea. On this cruise she operated with and , and although several attacks were made, no sinkings resulted. She returned to Fremantle 17 January 1945.

''Hammerhead'' departed on her fourth war patrol 19 February, in company with . Patrolling off Cape Varella, she detected a convoy and two escorts 23 February and while closing the cargo ships obtained a perfect shot on an escort. A spread of four torpedoes sank Japanese frigate ''Yaku''. Due to the illness of her commanding officer, the submarine was forced to end her patrol, and moored at Subic Bay 3 March 1945.

Fifth and sixth patrols, March – May 1945

Beginning her fifth war patrol 10 March 1945, ''Hammerhead'' proceeded to the coast of Indochina, where on 29 March she detected a large escorted convoy. Working her way inside the screen, the submarine was able to get a clear shot at an escort vessel, and a single hit broke her in two. After sinking the escort, ''Hammerhead'' damaged other members of the group before retiring. She returned from this war patrol 6 April 1945, mooring at Subic Bay, Philippines.

For her sixth war patrol ''Hammerhead'' operated in the Gulf of Siam. She arrived 6 May and that night encountered a small tanker and two escorts. After missing with two torpedoes at extreme range the submarine found the mark in a second attack, sinking the tanker ''Kinrei Maru''. ''Hammerhead'' attacked other ships of the convoy without success and after a depth charge attack decided to break off. Sighting a cargo carrier 14 May with only an aircraft escort, ''Hammerhead'' made a perfect approach and sank the ship with two torpedoes. She returned from this patrol 25 May.

Seventh patrol, June – August 1945

''Hammerhead'' departed Fremantle 21 June on her seventh and last war patrol, also carried out in the Gulf of Siam, in company with three other submarines. Her major attack of this patrol occurred 10 July, when she sank cargo ships '' ''Sakura Maru'''' and ''Nanmei Maru No. 5''. The patrol was brought to a close 21 August 1945 at Pearl Harbor.

Decommissioning, 1945

''Hammerhead'' arrived Mare Island, Calif., for decommissioning 20 August 1945 and decommissioned 9 February 1946. She was then placed in the Reserve Fleet at Mare Island.

1952–1953

''Hammerhead'' was brought out of reserve during the Korean War, recommissioned 6 February 1952, and engaged in training duty on the United States West Coast between San Diego and San Francisco, California, until 21 August 1953, when she decommissioned for return to the Reserve Fleet.

July–October 1954

Earmarked for loan under the Military Assistance Program, ''Hammerhead'' was converted to a GUPPY submarine at Mare Island Naval Shipyard and recommissioned once more 16 July 1954 to prepare for transfer. She was decommissioned on 23 October 1954 and loaned to Turkey the same day.

TCG ''Cerbe'' (S 341)

The submarine was commissioned by the Turkish Navy on 23 October 1954 as TCG ''Cerbe'' (S 03), the Turkish name of the island of Djerba. She was the first submarine of that name, a reference to the 1560 Battle of Djerba. She later was redesignated S 341. The United States formally sold ''Cerbe'' to Turkey on 1 January 1972. She was decommissioned on 4 May 1972 and subsequently scrapped.
