to control the buoyancy of a submarine
In war a submarine can hide under the water and attack without being seen.
to keep the sub level or help it to dive and surface
to keep the sub level or help it to dive and surface
This depends on both the role (e.g. missile, attack, research) and class of the submarine. The only thing that defines a submarine as nuclear is that it derives its power from nuclear reactors, it does not need to carry nuclear weapons (although almost all do).Role defines the purpose the submarine was designed to fulfillClass is the specific "model" of the submarine
YELLOW SUBMARINE In the town where I was born, Lived a man who sailed to sea, And he told us of his life, In the land of submarines, So we sailed on to the sun, Till we found the sea of green, And we lived beneath the waves, In our yellow submarine, We all live in a yellow submarine, yellow submarine, yellow submarine, We all live in a yellow submarine, yellow submarine, yellow submarine. And our friends are all aboard, Many more of them live next door, And the band begins to play. (Trumpets play) We all live in a yellow submarine, yellow submarine, yellow submarine, We all live a yellow submarine, yellow submarine, yellow submarine. (Full speed ahead, Mr. Parker, full speed ahead! Full speed over here, sir! Action station! Action station! Aye, aye, sir, fire! Captin! Captin!) As we live a life of ease Every one of us is all we need,(is all we need) Sky of blue, and sea of green,(sky of blue and sea of green) in our yellow(in our yellow) submarine.(submarine) ( Hahaha! ) We all live in a yellow submarine, yellow submarine, yellow submarine, We all live in a yellow submarine, yellow submarine, yellow submarine. (fading) We all live in a yellow submarine, yellow submarine, yellow submarine, We all live in a yellow submarine, yellow submarine, yellow submarine.
There are now 'Attack' submarines who's main purpose is to sink enemy submarines and ships and also Missile submarines whose main purpose is to launch ballistic missiles at the enemy.
The submarine had been envisioned by ancients as a weapon to be used against surface ships. Hundreds of years went by before technology allow construction of one. The "real" boats were around in a limited way in WWI, but by WWII, they kicked butt. Today, we have superb military submarines. The submarine was also seen as a research vessel and a recreational vehicle before they advent of the "real" submarine.
You drag the word "submarine" itself onto the submarine. Then you wait for it to sink.
An example of a robotic submarine is the ISE -AUV. - Two of these 3 ton Automatic Underwater Vehicles have been built in Vancouver's International Submarine ENgineering. The purpose of these torpedo shaped vehicles is to map Canada's northern oceans. The AUV's will cruise as deep as 1,500 feet and map mountains and valleys beneath the oceans surface.
"Yellow Submarine"because my friend had to play it for a exam.
