Modern submarines are designed to use every oceanographic element to tactical advantage, and the ocean environment is constantly monitored since it changes as the boat travels through different areas. The biggest concern is sound propagation in water, as water travels much faster in water than it does in air. Temperature, salinity, pressure, thermal layers, etc., all have an effect on how sound travels in the water. In the submarine world, the boat who hears the other one first wins.
It's not only the sound given off by a submarine, it's the sound received by it from other targets. Knowing how the environment affects the current sound profile helps determine if target information is being affected or not. For example, the Gulf Stream is much warmer than the surrounding ocean it flows through, and sound is greatly affected by temperature. A target bearing 090 can literally shift on Sonar several degrees as you pass through the Stream into cooler water due to temperature effect on sound.
Depth wise, the deeper you go, the more temperature and pressure becomes a variable in the sound equation for another submarine, and thermal layers can diffuse active sonar from surface ships, sonobouys (fixed-wing aircraft dropped) or helo dipping sonars making it much more difficult to detect.
On the engineering side, seawater is passed through an evaporator and the resultant fresh potable water is further refined for everything from oxygen generation to showers and laundry.
What else can I help you with?
How do submarines take advantage of forces in the water?
you cant see them under the water and so they can attack without being seen.
Why does a submarines density decrease when it pumps air out?
It doesn't pump air out; it forces water out of its ballast tanks to increase its buoyancy.
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.
Where do submarines go?
in the water
What is the advantage of a Power-Pole shallow water anchor?
The advantage of a Power-Pole Shallow Water Anchor is that it is for the serious fisherman. It has been designed for the smaller boat and helps with boat positioning.
How is a pink dolphin like submarines?
Pink dolphins are like submarines because they never go in the water, dolphins and submarines alike are have waterphobia and never go in the water. Pink dolphines also are lesbians like submarines
Can a plane run under water?
Harder to answer than you would think.If you had asked "AIRPLANE" the answer would be NOBut there have been submarines called Planes built.The little flap things on submarines are called Planes.So a Plane will work, But an Airplane designed for Air Use will not.
What is the function of a submarine?
A submarine is designed primarily for underwater operations, allowing it to navigate and conduct various missions beneath the surface of the water. Its functions include military applications such as surveillance, reconnaissance, and attacking enemy ships or submarines, as well as scientific research, exploration, and underwater construction. Submarines can remain submerged for extended periods, making them valuable for stealth and strategic advantage. Additionally, they can support deep-sea exploration and environmental monitoring.
Why cannot submarines go in deepest parts in oceans?
As submarines go deeper they are surrounded by more and more pressure from the water arround them. There are not currently any submarines that can withstand that amount of water pressure.
What are underwater bombs called?
Underwater bombs are commonly referred to as depth charges. These are explosive devices designed to be dropped or launched into water to destroy or disable underwater targets such as submarines.
How do submarines go forward?
Most submarines have propellers that spin, pushing them forward. A few smaller research submarines use a water jet for propulsion.
Why does submarines have to go under water?
Submarines are built with a special design that allows them to be faster underwater. Submarines can be used during a war as a way to sneak up to enemy lines in the water, but still stay hidden.
