A submarine is a watercraft capable ___MASK43___ independent operation underwater . It differs from a submersible , which has more limited underwater capability . The term most commonly refers to a large , crewed vessel . It is also sometimes used historically or colloquially to refer to remotely operated vehicles and robots , as well as medium - sized or smaller vessels , such as the midget submarine and the wet sub . Used as an adjective in phrases such as " submarine cable ", " submarine " means " under the sea ". The noun " submarine " evolved as a shortened form ___MASK43___ " submarine boat " ( and is often further shortened to " sub "). For reasons ___MASK43___ naval tradition , submarines are usually referred to as " boats " rather than as " ships ", regardless ___MASK43___ their size .

A boat is a watercraft ___MASK43___ a large range ___MASK43___ sizes designed to float , plane , work or travel on water . Small boats are typically found on inland waterways ( e . g ., rivers and ___MASK70___ ) or in protected coastal areas . However , boats such as the whaleboat were designed for operation from a ship in an offshore environment . In naval terms , a boat is a vessel small enough to be carried aboard another vessel ( a ship ). Another less restrictive definition is a vessel that can be lifted out ___MASK43___ the water . Some definitions do not make a distinction in size , as bulk freighters long on the Great ___MASK70___ are called oreboats . For reasons ___MASK43___ naval tradition , submarines are usually referred to as ' boats ' rather than ' ships ', regardless ___MASK43___ their size and shape .

An aircraft carrier is a warship that serves as a seagoing airbase , equipped with a full - length flight deck and facilities for carrying , arming , deploying , and recovering aircraft . Typically , it is the capital ship ___MASK43___ a fleet , as it allows a naval force to project air power worldwide without depending on local bases for staging aircraft operations .

There are eight species divided among two orders , the Amiiformes represented by a single living species , the Bowfin (" Amia calva "), and the Lepisosteiformes , represented by seven living species in two genera , the gars . Further species are to be found in the fossil record and the group is often regarded as paraphyletic .

A wet sub is a type ___MASK43___ underwater vehicle ( submarine ) that does not provide a dry environment for its occupants . Usually , wetsuited scuba divers will ride upon the device ( as one would ride a motorcycle or with an opening as in an Olympic bobsled ), although it can be designed to fully enclose its occupant ( s ) to provide lower drag .
