USS Hammerhead SS-364

The USS Hammerhead was a United States Navy Gato-class submarine which earned seven Battle Stars and a Navy Unit Commendation for her actions during World War II service. At 312 feet long, she carried a complement of 60 sailors and armament comprised of 10 x 21-inch torpedo tubes, 24 torpedoes, 1 x 3-inch / 50 caliber deck gun and four machine guns. Her endurance was 75 patrol days, or 48 hours underwater at a depth of 300 feet, at 2 knots per hour. Hammerhead's top speeds were 21 knots surfaced and 9 knots when submerged, and her range was 11,000 nautical miles if surfaced at 10 knots. This was possible due to a propulsion system of 4 x V16 diesel engines driving electrical generators, 2 x 126-cell batteries, 4 x high-speed electric motors with reduction gears and two propellers.

Many Successful Strikes

After her keel was laid down by the Manitowoc Shipbuilding Company of Wisconsin, Hammerhead was launched in October of 1943, and commissioned five months later. She received shakedown training and her initial trials in Lake Michigan before being towed down the Mississippi River to New Orleans on a floating dry dock. Her maiden cruise took her to the Canal Zone, for final war preparations, and then to Pearl Harbor, Hawaii, from which she departed on her first war patrol in June of 1944. While sailing near Formosa, USS Hammerhead's first battle experience resulted in her sinking an enemy sampan with gunfire. Before the month ended, she had also damaged several other ships before making port at Fremantle, Australia. On her next mission, she was ordered to Java and the South China Seas, and while there, was responsible for sinking five cargo ships. Although her next job was uneventful, in February of 1945, Hammerhead set sail for Cape Varella, where she sank Japanese frigate Yaku. Her following mission took her to the shores of Indochina, where she broke an escort vessel in two and damaged other vessels in the enemy convoy before mooring at Subic Bay in the Philippines. USS Hammerhead next stood out in the Gulf of Siam, where, in May, she sank the tanker Kinrei Maru as well as a cargo carrier. June found her in the same area, sinking cargo ships Sakura Maru and Nanmei Maru No. 5, before the war hostilities ended on August 15.

Retirement in Turkey

Hammerhead returned to Mare Island, California and was shortly decommissioned and placed in the Reserve Fleet until taken out for Korean War service duty. After being re-commissioned in February of 1952, she participated in training activities off the shores of San Diego and San Francisco for a year and a half. At that time, USS Hammerhead received a conversion to a GUPPY submarine and was subsequently transferred to the Turkish Navy in October, 1954. Her new name was TCG Cerbe, and she served under a loaned status until being purchased by Turkey in 1972. The former Hammerhead was scrapped not too long after that by the Turkish government.

Hammerhead seemed to have a very productive career; luck seemed to be with her from the onset of her journey into the war, and stayed with her for her total 29 years of service. In fact, the vessel aptly deserved its namesake of a shark, since it received a commendation for the patrol in which it sank 5 enemy ships in one battle. There is no documentation of collisions, accidents, or even minor mishaps, which speaks of both good fortune as well as a skillful and responsive crew. Not every ship was so blessed; there are numerous incidents of successful submarines finding themselves in the wrong place at the wrong time, or facing inclement weather, not to mention faulty equipment. The worst incidents Hammerhead faced involved returning to port after the illnesses of crew members. Hopefully, the sailors who served aboard her did not incur danger from another common peril that was unknown at the time: asbestos exposure. This insulation was heavily relied upon during the mid-twentieth century, and seemed ideal for the small, awkward spaces on submarines. It had a well-deserved reputation as a fire, heat and electrical retardant, and weighing practically nothing, could have been used everywhere on board. The Navy wished to protect its men from the horrible chance of fire, given any ship's limited escape routes and resources. However, if the asbestos sealant was damaged during repeated dives, depth charge explosions or overhauls, tiny fibers may have escaped and drifted through a ship's contained air system. It is now known that they have remained in bodies for decades and the long term irritation had been connected to serious medical conditions and even malignancies. That is why it is important that any former sailor from the USS Hammerhead see their doctor at the first sign of unusual physical symptoms, and then contact us for additional information.
