1943-1946

Trumpetfish (SS-425) was laid down on 23 August
1943 at Philadelphia, Pa., by William Cramp
Shipbuilding Co.; launched on 13 May 1946;
sponsored by Mrs. Oswald S. Colclough; and
commissioned on 29 January 1946,
Lt. Comdr. Raphael C. Benitez in command.

1946

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 /-4OO which had been
captured at the end of World War II. 

TRUMPETFISH returned to the east coast
for local operations out of New London, CT,
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.

1953
 
 

Attached to SubRon4, based at Key West, FL,
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.

1955-1956

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

1957-1959

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 Med. With the cessation of hostilities,
TRUMPETFISH resumed her Med 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, TRUMPETFISH
operated out of that base conducting
training and exercises into 1959.

1959-1961

During her next Med 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, SC. 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.

1962-1969

TRUMPETFISH resumed a schedule of local anti-
submarine warfare operations out of Charleston,
alternating deployments to the Med 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 1"
and Minibex" in 1963. After a Med deployment
 in early 1966, the ship took part in "Plumb
Bob II" and provided services for the David
Taylor Model Basin.

1970

Subsequently assigned the primary mission of
providing services for anti-submarine 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 USS 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 Ft. Lauderdale, FL, 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 USS HENRY CLAY (SSBN-625)
during the nuclear submarine's sea trials
off the Florida coast from 5 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.

1971

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 23rd, the submarine
departed for South American waters and
Operation "Unitas XII." Joining Task Force 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 TF86 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 TF86
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.

1972

TRUMPETFISH remained with SubRon4,
operating out of Charleston through 1972.
She deployed to the Caribbean again on
25 January 1973. Later conducting
torpedo tests off Newport, RI, 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, FL area preceded the ship's
arrival at Charleston on 15 August to prepare
for decommissioning.

1973-1990

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 1990.
