How long can a nuclear submarine last without refueling?

about twenty years
Nuclear power allowed submarines to run for about twenty years without needing to refuel. Food supplies became the only limit on a nuclear submarine’s time at sea. Since then, similar technologies have been developed to power aircraft carriers.

How long do sailors spend on a submarine?

Deployments on a submarine can vary in length, depending on the type of submarine. Overall assignments last three years. On a ballistic missile sub, two full crews rotate shifts to allow the vessel to remain at sea as often as possible. Each crew may serve for about 60 to 80 days before resurfacing and rotating out.

How long will the nuclear power plant last on a submarine?

When that vessel is launched, the onboard nuclear power plant is expected to last its entire 40-year service life. That is seven years longer than the current reactors aboard U.S. submarines. “Our goal for the new submarines is to have a life-of-the-ship reactor,” said Frank G.

What are the advantages of nuclear-powered submarines?

The performance advantages of nuclear submarines over “conventional” (typically diesel-electric) submarines are considerable. Nuclear propulsion, being completely independent of air, frees the submarine from the need to surface frequently, as is necessary for conventional submarines.

Why do submarines take so long to refuel?

Refueling subs can take longer than two years because they become stuck back behind carriers, he said. Nuclear power plants aboard submarines are the most expensive and difficult to maintain because of the tight space. To make them last longer, it requires more highly enriched uranium than what would be needed at a land-based plant, he added.
