Essay On Submarines

INTRODUCTION: A Submarine is basically an autonomous vessel or a watercraft with large crew which does underwater operations. It is pretty different from a traditional submersible, which has very limited underwater capability. Generally, Small or medium sized underwater vessels and remotely operated bots are often referred to as Submarines. HISTORY:
Submarine means “under the sea”. The word submarine is evolved from shortened form of submarine boat. Regardless to their immense size the submarines are usually referred to as “boats” rather than “ships” due to reasons of naval tradition.
Design of submarine took off during the early 19th century which were adopted by many navies, but experimental submarines were widely built much before

In earlier designs, a separate pressure hull known as the “conning tower” which is featured above the main body of boat that helps in the usage of smaller periscopes.
In earlier designs, the submarine consists of an additional pressure hull known as the “cunning tower” which is featured above the main body which helpein usage of smaller periscopes. Submarine also contains various hydrodynamic control fins, ballast tanks and also a propeller or pump jet at the rear. Design of deep diving, smaller and specialty submarines differ from the traditional layout.
There are widest range of capabilities and types of submarine than that of any vessel. From small autonomous robots and one or two person vessels that operate for few hours to vessels that can remain submerged for several months like the one with nuclear power. Submarines can work at greater depths which are not survivable for human divers. Modern deep diving submarines are derived from the bathyscaphe which in turn is evolved from the traditional diving
