1972
Development was underway on the next-generation
submarine-launched ballistic missile, Trident, C-4,
which had twice the range of the C-3. A C-4-equipped submarine
could launch at the most logical targets in the Cold War world
while sitting in New York harbor. The U.S. would no longer
need to maintain overseas submarine bases in Scotland, Spain,
and Guam, and the Navy closed those bases when the C-4 became
operational. The C-4 missile first flew in January 1977.

this class, the first of which entered service in
1981.

The C-4 did pose some problems for the people who design
submarines. Too large to fit in any extant sub design,
Trident required a new, very large class of submarine:
Ohio, 560 feet long, 42 feet wide, 16,674 tons.
1974
The U.S. Central Intelligence Agency attempted to raise a
Soviet Golf-class diesel-powered boat, K-129, which
sank in 1968. The agency did so under cover of a deep-ocean
mineral recovery effort using a ship built for the purpose,
the Glomar Explorer. The submarine apparently broke
apart and the stern half fell back to the bottom.
1982
During the Falklands War, two British ASW carriers, more than
a dozen other surface warships, five submarines (four of them
nuclear), and even patrolling aircraft became occupied at
certain times in protecting the force against two badly
maintained, poorly manned Argentine submarines. One was a
post-World War II Guppy and the other an eight-year-old
German boat that, in the end, had nil effect upon the war.
Be not deceived by this comic-opera vignette, however. For the
British, the submarine war was deadly serious. With two World
War II-vintage torpedoes, the British submarine
Conqueror sank the World War II-era Argentine cruiser
Belgrano (ex-USS Phoenix), killing 368 sailors.
1982
Planning began for the next-generation American attack
submarine: another Seawolf, SSN-21. The Navy adjusted
the hull number (the next in the series would have been 774)
to celebrate Seawolf as the "submarine of the 21st
Century." It features the most sophisticated systems
imaginable. Size: 353 feet long, 40-foot diameter, 8,000 tons.
Top speed: probably in excess of 35 knots. According to one
program manager, when underway at quiet speed,
Seawolf would be as quiet as a Los Angeles boat
sitting at the pier. Quiet speed may be in excess of 20 knots.
1986
On October 6, a Soviet Yankee-Class nuclear-powered
missile boat, K-291, sank in the Atlantic 680 miles
northeast of Bermuda, from an explosion in a missile tube.
1989
Soviet submarine Komsomolets sank in the Norwegian Sea.
Most of the crew abandoned ship, but while waiting for rescue
in the frigid waters, 34 of them died from hypothermia, heart
failure, or drowning. This accident prompted the Russians to
develop individual escape survival suits rated to a depth of
328 feet, and led the U.S. Navy to adopt the Mark 10
British-designed Submarine Escape Immersion Module. This
provides individual full-body thermal protection and has been
tested to 600 feet.

1997
In preparation for development of the next submarine class (Virginia),
the U.S. Navy elected to create a one-fourth-scale, unmanned
submarine to test new and emerging technologies before they
are committed to full-scale ships. Designated the Large Scale
Vehicle (LSV) 2 and named after a species of trout,
Cutthroat, the 111-foot boat is scheduled for delivery
to the Navy in the spring of 2001.
2000
The U.S. Navy is testing Avenger, a 65-foot
mini-submarine with a closed-cycle engine powered by diesel
fuel and liquid oxygen. Intended for use by SEALs, the Navy's
clandestine amphibious assault teams, Avenger can carry
18 troops and a crew of six.
2000
The Russian missile attack submarine Kursk, K-141 sank
while on maneuvers in the Barents Sea. Placed in service in
1995, the 510-foot Oscar II-class Kursk had a surface
displacement of 14,700 tons and speed in excess of 30 knots.
On August 12, the sound of at least two explosions reached the
Norwegian Seismic Service and five other ships operating in
the area, including two American and one British submarine
shadowing the exercises. The cause of the accident remains
unknown, although Kursk had radioed for permission to
launch an exercise torpedo about an hour and a half earlier.

Kursk went down in about 350 feet of water with 118
men. Although the boat bore several escape systems, including
individual escape-survival suits, none was used. Efforts to
reach Kursk were hampered by bad weather. Eventually,
during recovery of bodies, search teams determined that at
least 23 sailors survived the initial explosion, only to
perish later. Russia has contracted with several firms to help
remove crew remains, and plans for raising Kursk are
under discussion.
2000
In this year of the 'official' 100th anniversary of the
submarine (dating from the U.S. Navy purchase of the
Holland in 1900), some 47 nations operate more than 700
submarines, almost 300 of them nuclear-powered. A host of
countries, including the United States, Germany, Italy,
Denmark, Norway, Sweden, and Japan, are pursuing new designs.
In short, the submarine appears to be in the best of
international health.
