How long could a WWII submarine stay submerged?
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.
Right now, a periscope or snorkel can be easily be detected by a single scan of a modern surface search radar. Even in WW 2, submarines were easily detected using hydrophones (passive listening) and radar operators if a scope or snorkel were raised long enough.
How deep did World War 2 submarines go?
World War II German U-boats generally had collapse depths of 200 to 280 metres (660 to 920 feet).
How long does it take for a submarine to dive?
In a World War II-era boat, the whole operation could take as little as 30 seconds with a well-trained crew. In contrast, an Ohio-class ballistic-missile submarine may take as long as five minutes to reach periscope depth from the surface.

How fast can a submarine go underwater?
Two 126-cell battery groups gave her a submerged top speed of 8.75 knots (16.2 km/hr); holding her speed to 2 knots (4 km/hr), she could remain submerged for 48 hours. The Gato -class USS Robalo (SS-273) was launched in May 1943, 1 of 27 wartime boats built at Manitowoc Shipyard, Wisconsin. Submarines were normally launched stern first.
Can underwater acoustics detect submarines?
One of the issues with using underwater acoustics as a submarine detection device is that it is unfeasible to get an aircraft down into the water to listen and ping for the submarine. This is why the disposable sonobuoy was developed during the Second World War.
How were submarines launched?
Submarines were normally launched stern first. This unusual sideways technique was necessary because the shipyard was on the banks of a narrow, winding river. The boat’s test dives took place in Lake Michigan, before she was barged down the Mississippi to the sea.
