A nuclear submarine is a submarine powered by nuclear reactor technology, as opposed to a more conventional submarine layout consisting of air-breathing diesel engines which are used to charge batteries for underwater running. The performance advantages of nuclear submarines over conventional submarines are large; nuclear propulsion, being completely independant of air, frees the submarine from the need to frequently surface, as is necessary for conventional submarines; the large amounts of power generated by a nuclear reactor allow nuclear submarines to operate at high speed for long durations; and the long interval between refuellings grant a range limited only by consumables such as food - current generations of nuclear submarines never need to be refueled throughout their 25-year lifespans. Conversely, the limited power stored in electric batteries means that even the most advanced conventional submarine can only remain submerged for a few days at slow speed, and only a few hours at top speed; recent advances in Air-independent propulsion have eroded this advantage somewhat. The high cost of nuclear technology means that relatively few states have fielded nuclear submarines.
