# At what depth do submarines cruise?

## At what depth do submarines cruise?

It’s generally accepted that the maximum depth (depth of implosion or collapse) is about 1.5 or 2 times deeper. The latest open literature says that a US Los Angeles-class test depth is 450m (1,500 ft), suggesting a maximum depth of 675–900m (2,250–3,000 ft).

## What was the max depth of a ww2 submarine?

World War II German U-boats generally had collapse depths in the range of 200 to 280 metres (660 to 920 feet). Modern nuclear attack submarines like the American Seawolf class are estimated to have a test depth of 490 m (1,600 ft), which would imply (see above) a collapse depth of 730 m (2,400 ft).

At what depth does a submarine crush?

The crush depth of most submarines is classified, but it’s likely to be more than 400 metres. The ARA San Juan search location straddles the edge of the continental shelf, where ocean depths vary, but reach as deep as 3,000 metres.

Do subs ever hit whales?

Most subs have two types of sonar: active and passive. Active sonar sends out acoustic sounds, or “pings,” which can reach thousands of yards. If the ping bounces back, that means it hit an object—like a whale, a ship, or another submarine.

### What is periscope depth of submarine?

For a sub to receive these radio-frequency or satellite messages, it must stop what it is doing within that time period, extend an antenna and rise to “periscope depth”— approximately 60 feet (18 meters) below the surface, which is shallow enough to use a periscope.

### Which military sub can dive the deepest?

Victor Vescovo set a new deep-diving record and is the first human to make multiple dives, solo, to its depths in the DSV Limiting Factor (Triton 36000/2 model submersible) the world’s deepest diving, currently operational submarine.

How deep can a Vanguard submarine dive?

Tigerfish had a range of 13-29 km depending on the homing configuration and could dive down to 442 m, though these torpedoes were withdrawn from the Royal Navy in 2004….Ballistic missile submarine.

How far up can periscopes go?

A traditional periscope is up to 60 feet long, so that the hull can remain hidden underwater while the periscope lifts up hydraulically to poke up out of the waves. It provides a direct optical view of the surface, thanks to prisms and lenses. The new optronic masts no longer penetrate the hull.
