What else can I help you with?
What did the Japanese use against US submarines?
Depth charges.
What is an underwater bomb used to attack submarines?
The weapon described is a depth charge.
How did airplanes destroy submarines?
Airplanes dropped depth charges and specialised torpedoes
How is a submarine used for pleasure?
Most pleasure submarines are either personal watercraft with limited diving capability, or tourist submarines with limited depth capability.
Do you feel waves in a submarine?
No, submarine crews do not generally feel waves when operating submerged. During "normal" undersea operations, submarines are almost always below a depth that would cause them to react to wave action.
Can a submarine go to the bottom of the sea?
Define "submarine" and "bottom of the sea".Submarines are designed for a particular pressure/depth. The designers also incorporate a margin of error, so the actual depth at which the submarine would be crushed by external pressure ("crush depth") is generally marginally greater than its "design depth". Submarines normally operate at a fraction of their design depth (this is called "test depth") under normal peacetime conditions. Different navies use different fractions as the test depth; the German navy specifies a test depth of half the design depth, while the US navy uses 2/3 of design depth.If the sea floor depth at a particular point is less than the sub's test depth, then they can approach it (though, for various reasons, actually touching it is nearly always a bad idea).The deepest known point in the ocean is the Challenger Deep in the Marianas Trench, at about 10,916 meters. Two human-manned vessels (one solo craft and one with two occupants) have gotten within a few meters of the bottom there, but both of them were technically "submersibles" rather than "submarines"; they had limited mobility and basically existed to go primarily straight down (and, hopefully, back up) rather than cruise for long distances horizontally. Actual submarines generally have much lower design depths. For example Virginia-class US nuclear attack submarines have a test depth of only about 240 meters (putting their design depth at about 360 meters).
What is the normal depth of a bookshelf?
The normal depth of a bookshelf is typically around 10 to 12 inches.
Can sonar use in periscope depth?
Yes sonar can be used at periscope depth. Surface ships also have sonar arrays on them. They are usually used to detect submarines.
How can a submarine stay submerged at certain depth underwater?
The military submarines maintain depth by use of the planes. As they move through the water, a little up or down "tilt" on the planes will keep the boat at the correct depth.
Why submarines need a thick hull to go deeper?
Because thin metals will crush under extreme depth
How far can submarines dive?
U.S. Submarines can dive 800-plus feet. (Official depth; however, can dive deeper. The US Navy itself acknowledges that most of it's attack submarines can operate down to at least 985 feet, and many to over 1400 feet.
What is the difference between a normal ship and a submarine?
Normal ships are designed to move on the surface of the water. Submarines are designed to be able to submerge and travel under the water's surface, as well as on the surface. When normal ships go down, they stay down. Submarines are able to come back up after they go down. All American submarines are nuclear powered. With the exception of Aircraft carriers, surface ships are powered conventially.
