They were the largest of their kind in the United States, with swimming pools, saunas, golf courses, and three football fields on each side. The Soviet Union built nuclear giants like these during the Cold War to face off against the US and its allies. The Typhoon Class Russia/Project 941 Class.

Ohio-class nuclear-powered submarines are the 14 ballistic missile submarine (SSBNs) and four cruise missile submarine (SSGNs) of the United States Navy…. In recent years, nuclear submarines have also been used for research purposes, such as studying the ocean floor and conducting undersea mapping missions.Īccording to the Government Accountability Office’s most recent annual report on major US weapons systems, the cost of the 12- vessel Columbia class nuclear missile submarine has risen by $3.4 billion to a projected $112 billion before its first planned deployment in 2031. Nuclear submarines are designed for a variety of missions, including surveillance, reconnaissance, and the delivery of nuclear weapons. Nuclear submarines are equipped with a variety of advanced technology, including sonar, which allows them to detect other submarines and underwater obstacles. This means that they can stay submerged for months or even years at a time. Nuclear submarines are powered by a nuclear reactor, which provides them with an unlimited supply of energy.

That’s equivalent to around two hundred and fifty adult blue whales! The largest nuclear submarine ever built was the Soviet Union’s Typhoon-class submarine, which weighed in at a whopping 33,800 tonnes. Nuclear submarines are the largest and heaviest type of submarine, with some weighing in at over 18,000 tonnes.
