Any of several fishes so-called for their deep, compressed body and long, tubular snout.
Trumpetfish (SS-425) was laid down on 23 August 1943 at Philadelphia, Pa., by William Cramp Shipbuilding Co.; launched on 13 May 1945; sponsored by Mrs. Oswald S. Colclough; and commissioned on 29 January 1946, Lt. Comdr. Raphael C. Benitez in command.
A combined shakedown and goodwill cruise to Caribbean ports in the early spring of 1946 preceded the submarine's westward cruise to Pearl Harbor. Highlighting the ship's training operations in Hawaiian waters was her intentional torpedoing of the large Japanese submarine I-400 which had been captured at the end of World War II.
Trumpetfish returned to the east coast for local operations out of New London, Conn., and, late in 1946, was briefly based at Annapolis to conduct training cruises for Naval Academy midshipmen. In the summer of 1947, as the ship underwent a Guppy II conversion, her hull was streamlined, a snorkel system was added, and higher capacity batteries were installed. The net result of the conversion enhanced the ship's offensive capabilities and increased her maximum submerged speed.
Attached to Submarine Squadron 4, based at Key West, Fla., Trumpetfish conducted local operations and training exercises off the east coast. In September 1953, she participated in NATO Exercise "Mariner" and then was deployed to the Mediterranean with the 6th Fleet.
After returning home, the ship operated along the east coast and in the Caribbean through 1955. Following duties out of Key West in January and February 1956, Trumpetfish proceeded to Guantanamo Bay for service with the Fleet Training Group. In July, the ship took part in midshipmen training cruises from Annapolis to Guantanamo Bay and back.
In the fall of 1956, the ship joined a hunter-killer group for a deployment to Europe and the Middle East. Departing Norfolk on 1 October 1956, Trumpetfish sailed for European waters and participated in training exercises as she crossed the Atlantic. After calling at Brest, France, Trumpetfish suddenly received word of a crisis in the Levant.
President Nasser of Egypt had nationalized the previously British-owned Suez Canal, and prevailing Arab-Israeli tensions had erupted into warfare while British and French troops attacked Egyptian positions. Trumpetfish made her best speed for Suda Bay and joined the 6th Fleet in peace-keeping missions in the eastern Mediterranean. With the cessation of hostilities, Trumpetfish resumed her Mediterranean cruise, operating briefly with the Italian fleet before returning to Key West on 28 January 1957.
The submarine conducted local operations out of her home port until 29 August, when she got underway for European waters and fall NATO exercises. Air, surface, and submarine forces of NATO nations engaged in tests and exercises to hone their capabilities to defend the NATO nations against possible aggression. After returning to Key West on 25 October, Trumpet-fish operated out of that base conducting training and exercises into 1959.
During her next Mediterranean deployment, she snorkeled through the Strait of Bonifacio between Corsica and Sardinia. In August 1959, as part of Atlantic Fleet dispersal plans, Trumpetfish's home port was changed to Charleston, S.C. During January and February of 1960, the submarine took part in operations in the North Atlantic before briefly visiting Scotland. She subsequently participated in exercises in the western Atlantic Ocean, before a major refit at Charleston during 1961 modernized the ship to a Guppy III configuration. The alterations increased her capabilities by adding 15 feet to her length, by giving her better weapons and electronics, and by extending her range.
Trumpetfish resumed a schedule of local antisubmarine warfare operations out of Charleston, alternating deployments to the Mediterranean and duty with the 6th Fleet. She participated in emergency operations during the tension precipitated by the Cuban Missile Crisis in October 1962. The submarine later participated in several inter-type fleet exercises in home waters and in the Caribbean. Trumpetfish underwent a routine yard period at Charleston before taking part in Exercises "Plumb Bob I" and "Minibex" in 1965. After a Mediterranean deployment in early 1966, the ship took part in "Plumb Bob II" and provided services for the David Taylor Model Basin.
Subsequently assigned the primary mission of providing services for antisubmarine warfare forces, Trumpetfish stood ready to conduct mining and reconnaissance missions as well. On 12 January 1970, the submarine departed Charleston for Cape Kennedy, provided services en route to Remora (SS-487), and conducted type training exercises. A port visit to Cape Kennedy occupied 16 to 18 January, before the submarine got underway for Fort Lauderdale, Fla., to provide services for the Naval Ordnance Laboratory Test Facility (NOLTF) there. Ten days of local operations at the NOLTF preceded the ship's providing services for Henry Clay (SSBN-625) during the nuclear submarine's sea trials off the Florida coast from to 8 February. Subsequently taking part in Operations "Springboard" and "Exotic Dancer III," Trumpetfish headed for Philadelphia and a yard overhaul which would last through the summer and fall and into December 1970.
After the long overhaul, the submarine participated in type and refresher training off the east coast before she headed for the Caribbean in the spring. Among her activities were those which provided services for the German Republic's destroyer Lutjens between 7 and 14 May. The exchange of several crew members with the German ship during this time provided a valuable and enlightening experience.
On 5 June, after participating in a fleet mine test, Trumpetfish commenced six weeks of pre-deployment upkeep, with sea trials from 12 to 16 July. On the 23d, the submarine departed for South American waters and Operation "Unitas XII." Joining Task Force (TF) 86, Trumpetfish arrived at Cartagena, Colombia, on 6 August, prior to transiting the Panama Canal to proceed down the Pacific coast of South America. She crossed the equator on 20 August and made port at Callao, Peru, on the 30th. The ship operated with TF 86 for two weeks after the four-day port visit at Callao, before arriving at Valparaiso, Chile, on 17 September.
The submarine traversed the inland waterway and the Strait of Magellan and arrived at Punta Arenas, Chile, on 4 October. She conducted operations during "Unitas XII" off the Atlantic coast of South America, with visits to Mar Del Plata, Argentina, and Rio de Janeiro, Brazil, before rejoining TF 86 at La Guaira, Venezuela, on 2 December. Bidding farewell to the task force four days later, the ship sailed for Charleston and arrived at her home port eight days before Christmas 1971.
Trumpetfish remained with SubRon 4, operating out of Charleston through 1972. She deployed to the Caribbean again on 25 January 1973. Later conducting torpedo tests off Newport, R.I., the submarine operated with British aircraft carrier HMS Ark Royal off San Juan, Puerto Rico, in May, before returning to Charleston on the 30th of that month. Upkeep, type training, and services for Patrol Wing 11 in the Jacksonville, Fla., area preceded the ship's arrival at Charleston on 15 August to prepare for decommissioning.
On 15 October 1973, at Charleston, Trumpetfish was decommissioned and struck from the Navy list. She was next turned over to the Brazilian government and renamed Goiaz (S-15), with Commander Edouardo Russo her first commanding officer. As Goiaz, the submarine operated with the Brazilian Navy into 1980.
