USS TREPANG (SSN-674)
The second Trepang (SSN-674)
was laid down on 28 October 1967 at
Groton, Conn., by the General Dynamics Electric
Boat Division; launched on 27 September 1969; sponsored by Mrs. Melvin R. Laird, wife of the Secretary of Defense; and commissioned on 14 August
1970, Comdr. Dean Sackett, Jr., in
operations out of New London, Conn., Trepang proceeded to the
Arctic early in 1971. From 22
February to 22 March, the nuclear attack submarine operated beneath the
northern ice cap, conducting extensive
tests to provide data for her weapons systems, as well as carrying out scientific experiments concerning the movement, composition, and geological history
of the cap itself.
After returning to New
London via Faslane, Scotland, Trepang
was soon deployed to the warmer climes of the Caribbean, departing from her
home port on 22 April and subsequently
making port at Frederiksted, St.
Croix, Virgin Islands, for weapons systems acceptance and evaluation trials. Back in New England waters for local
operations, Trepang again headed south for further tests. Later in the
year, in November, the submarine conducted
independent operations in the North Atlantic.
Following her return to
her homeport on 5 February 1972, she subsequently underwent standdown and upkeep,
as well as type training and equipment grooming in local operating areas. During this period, Trepang again conducted a second extended deployment into
the northern Atlantic from 24 July
to 25 September 1972, returning to New
London via Halifax, Nova Scotia. For
the remainder of the year, Trepang operated off the east coast between New London and Ft. Lauderdale, Fla.
An interim four-week
drydocking period at the Portsmouth (N.H.) Naval Shipyard preceded the
ship's 1973 operations, before the attack
submarine headed south for weapons
tests off the Florida coast. Completing a four-week upkeep period on 22 April, the ship completed a Nuclear Technical Proficiency Inspection
before returning to New London, where she completed an Operational
Reactor Safeguards examination on 4 May.
On 8 June, Trepang departed
New London for a six-month deployment
with the 6th Fleet in the Mediterranean.
She participated in several special operations with this Fleet during the increased tension brought on by the Yom Kippur War in the Middle East in
October 1973. The attack submarine
returned to her home port at the end
of November 1973 for upkeep and standdown leave period.
Trepang got underway on 15 February 1974 for a special operation which lasted through 9 April.
The ship then spent three days at Holy Loch, Scotland, before sailing
for New London. She continued local operations
and training off the east coast through her change of home port on 1 October 1974, when the submarine was assigned to Portsmouth, N.H. She spent the
remainder of the year 1974 in drydock in annual overhaul.
Trepang was assigned to Submarine Squadron 10 during March 1975. She spent the period from April to August completing the overhaul and carrying out
crew training and recertification. Following sea trials in late October, Trepang returned to New
London on 7 November for an intensive
post-overhaul upkeep alongside Fulton
Departing New London on 1 December, Trepang conducted post-overhaul weapons systems
acceptance testing at Roosevelt Roads,
Puerto Rico, and five days of acoustic trials off Frederiksted, St. Croix,
Virgin Islands, before departing St.
Croix on 17 December and returning to New London on 22 December.
Trepang spent the early part of the year 1976 preparing
for an extended cruise. She deployed to the Mediterranean from June to
November, operating with the 6th Fleet. She returned to New London upon conclusion of the deployment and observed
post-deployment standdown into 1977.
In mid-January 1977, Trepang
participated in Exercise "CARIBEX 77." The spring was
devoted to individual ship exercises which
included a Nuclear Technical
Proficiency Inspection (NTPI), a Mk-48 Torpedo Proficiency Inspection, and an
Operational Readiness Inspection, all
of which were completed successfully. An
extensive refit period, which included drydocking, took place in May and
early June. Midshipman orientation cruises followed; and, in September, Trepang
conducted pre-deployment work-up and
certification. The nuclear attack
submarine then engaged in an Atlantic training mission from mid-October
to mid-December with the ship returning to
Groton in time for Christmas.
January 1978 found Trepang
finishing a post-deployment
standdown. The remainder of January, February, and March were devoted to type
training and participation in NATO
Exercise "Safepass." Trepang spent the summer working
up for a scheduled Mediterranean deployment.
The deployment was subsequently cancelled
to permit the ship's participation in a special CNO project. The remaining months of 1978 were spent in the evaluation of project-associated
equipment, with alternate periods at
sea followed by periods in port
devoted to equipment maintenance. Trepang departed Groton on 27 November to conclude the year at sea while continuing to participate in the
