1955 (69 years ago)(1955)[ 1 ] A nuclear submarine is a submarine powered by a nuclear reactor, but not necessarily nuclear-armed. Nuclear submarines have considerable performance advantages over "conventional" (typically diesel-electric) submarines. Nuclear propulsion, being completely independent of air, frees the submarine from the need to ...
USS Nautilus (SSN-571) was the world's first operational nuclear-powered submarine and on 3 August 1958 became the first submarine to complete a submerged transit of the North Pole. Her initial commanding officer was Eugene "Dennis" Wilkinson, a widely respected naval officer who set the stage for many of the protocols of today's Nuclear Navy ...
Armament. 6 × 21-inch (533 mm) torpedo tubes. USS Seawolf (SSN-575) was the third ship of the United States Navy to be named for the seawolf, the second nuclear submarine, and the only US submarine built with a liquid metal cooled (sodium), beryllium - moderated [2][3] nuclear reactor, the S2G. [4] Her overall design (known as SCB 64A) was a ...
Ballistic missile submarines. The UGM-27 Polaris missile was a two-stage solid-fueled nuclear-armed submarine-launched ballistic missile (SLBM). As the United States Navy 's first SLBM, it served from 1961 to 1980. In the mid-1950s the Navy was involved in the Jupiter missile project with the U.S. Army, and had influenced the design by making ...
The introduction of nuclear armed rockets, like the MGR-1 Honest John, reflected a change in both nuclear technology and strategy. Early nuclear armed rockets—such as the MGR-1 Honest John, first deployed by the U.S. in 1953—were surface-to-surface missiles with relatively short ranges (around 15 mi/25 km maximum) and yields around twice ...

An early stage in the "Trinity" fireball, the first man-made nuclear explosion, 1945. The United States developed the first nuclear weapons during World War II in cooperation with the United Kingdom and Canada as part of the Manhattan Project, out of the apprehension that Nazi Germany would develop them first.
There are three major types of submarines in the United States Navy: ballistic missile submarines, attack submarines, and cruise missile submarines. All submarines currently in the U.S. Navy are nuclear-powered. Ballistic missile submarines have a single strategic mission of carrying nuclear submarine-launched ballistic missiles.
