How long can a Virginia class submarine stay submerged?
three months
Virginia Class submarines employ advanced technologies to increase fire power, maneuverability, and stealth. The 377 feet (115 m) long submarine is capable of submerged speeds of more than 25 knots/29 mph (46 km/h) and can stay submerged for up to three months at a time.
How long can a nuclear submarine go 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.
How long can a submarine stay underwater ww2?
After 48 hours, it would be unbearable and you would have to surface. The World War II submarine that had the longest possible underwater endurance was the German Type 21. It could stay down for up to 75 hours, which gives you a tad over 3 days.
How deep can a 688 class submarine go?
1,475 ft
Although Tyler cites the 688-class design committee for this figure, the government has not commented on it. The maximum diving depth is 1,475 ft (450 m) according to Jane’s Fighting Ships, 2004–2005 Edition, edited by Commodore Stephen Saunders of the Royal Navy.
How long can a nuclear submarine stay underwater?
A nuclear submarine can stay and operate underwater for a couple decades, so long as it’s adequately stocked with enough supplies and ration for its onboard crew to survive that long.
Why do submarines come to the surface once every few days?
It lets the sub’s crew have a view of the surrounding horizon while the sub remains submerged. A submarine comes to the surface once every few days (or even more frequently than that), not only to get a fresh supply of atmospheric oxygen from above the water’s surface, but also to dispose of the waste gases that it produces onboard.
How do AIP submarines compare to conventional submariners?
While some conventional submarines can handle the distance, none have comparable underwater endurance. AIP submarines have narrowed the gap, however. While old diesel submarines needed to surface in a matter of hours or a few days at best to recharge batteries, new AIP powered vessels only need to surface every two to four weeks depending on type.
What are the advantages of nuclear-powered submarines?
Nuclear reactors are quieter, don’t consume air, and produce greater power output, allowing nuclear submarines to remain submerged for months instead of days while traveling at higher speeds under water. These advantages led the U.S. Navy to phase out its diesel boats in favor of an all-nuclear powered submarine fleet.
