Then, submarines were both powered by reactors and armed with ballistic nuclear weapons. The development of nuclear submarines followed a similar arch with both nations - first, submarines were developed that were powered by nuclear reactors but still used non-nuclear armaments. A few years after the Nautilus, an alarmed Soviet Union developed its own nuclear submarine capabilities. Over time, the submarines were armed with ballistic missiles capped with nuclear warheads. By this time, more advanced technologies were being developed and Nautilus functioned as a trainer sub after 1966.īeing able to travel the globe undetected meant that enemy military and commercial ships were exposed to submarine attack at any time and virtually any place on the Earth's oceans. Then it was assigned to the Sixth Fleet in 1960. After it reached the North Pole, the Nautilus was overhauled and had its reactor changed. Just a few years after being put to sea, the Nautilus became the first submarine to sail beneath the arctic ice, reaching the North Pole on Aug. While submarines previously were maintained for coastal defense, this new breed of submarine could - and did - travel the globe.

The incredible range and maneuverability of nuclear submarines radically altered naval strategy and tactics.
