nuclear sub
Reactor-powered undersea vessel
A nuclear sub is a submarine powered by a nuclear reactor rather than diesel engines or batteries.
Nuclear propulsion allows subs to remain submerged for months without refueling, limited mainly by food supplies and crew endurance.
The term typically refers to military vessels—either attack submarines or ballistic missile submarines carrying nuclear weapons: The nuclear sub surfaced near the Arctic ice shelf.
