Submarines, or subs, can stay submerged for varying lengths of time depending on their design and capabilities. Generally, military submarines can remain submerged for several months, as they produce their own oxygen and have systems to manage waste and food supplies. However, the practical limit is often around 90 days due to crew endurance and supply constraints. In contrast, smaller, non-military subs, like research submarines, have shorter durations, typically ranging from a few hours to a few days.

How long can a World War 2 sub stay under water?
A German type VII U-boat could stay submerged for about 24 hours before it had to resurface to replenish its air supply. This air supply could be extended somewhat by limiting activities of the crew while submerged. The type IX could stay submerged for 11 days. The snorkel in 1943 allowed German subs to stay submerged and refresh air. All other US/UK/Jap etc subs could stay down 2 days before having to vent for fresh air and recharge batteries.
How long can submarines stay under the ice?
Nuclear Submarines can stay almost indefently for them it is a question of Stores (food). Diesel Submarines are really not designed for under ice operations. AIP Subs can stay submerged for prolonged periods depending on the amount of Liquid Oxygen it has.
How long can nuclear subs stay submerged?
Many months! The biggest limitation is the amount of food they can carry for the crew. The actual limits are classified. Submarines can produce their own air and water and with nuclear power they could stay submerged indefinitely. The limiting factor is the amount of storage space (there is not much) on a sub for food and the the size of the crew onboard that consumes it. The larger SSGN's can stay submerged longer than the SSN's because they have more storage space.
How long could a Type VII Uboat stay submerged?
24 hours
How long could a world war 2 submarine stay submerged?
24 hours
How long can you survive in a submarine without resurfacing?
The length of time a submarine can stay submerged without resurfacing depends on its design and capabilities. Some modern submarines can stay submerged for several months, while others may only be able to stay submerged for a few days. It is important for submarines to resurface periodically to replenish supplies and allow for maintenance and crew rest.
How long would stay under water if you are one of jehovahs wintess getting baptiized?
Just long enough to be fully submerged - one to three seconds
How long can a submarine stay under the water?
For modern nuclear subs, they could theoretically stay under indefinitely. Of course, there's a crew which has to eat and bathe, and food and toiletries do eventually run out.
Can sperm whales stay submerged for up to two days?
No
What kinds of mini-subs did the Japanese use at Pearl Harbor?
At Pearl Harbor, the Japanese used the HA-19 (type A) which had a complement of two crewmen; was 78 feet long, 6 feet wide, and a draft of 6 feet. It was armed with two torpedo tubes, which fired a 45cm type 97 torpedo. It was powered by a one shaft electrical motor which could move it at 23 knots at the surface, and 19 knots submerged. While submerged at 2mph, it had a range of approximately 100 miles. Mini subs (Midget Subs) had to be carried by mother submarines. I Boats, such as I-24, carried some of the attacking Mini-Submarines to their pre-attack areas for the Pearl Harbor assault on 07 December 1941.
Where do hippos have babies?
Hippos are born under water, they can stay submerged for extended periods.
How do nuclear subs derive their power?
Nuclear submarines derive their power from a nuclear reactor that generates steam to drive turbines, which in turn propel the submarine. The nuclear reactor uses enriched uranium fuel to sustain a controlled nuclear reaction, providing continuous power without the need for refueling for extended periods underwater.
