Frigate
–
A frigate /ˈfrɪɡᵻt/ is any of several types of warship, the term having been used for ships of various sizes and roles over the last few centuries. In the 17th century, this term was used for any warship built for speed and maneuverability and these could be warships carrying their principal batteries of carriage-mounted guns on a single deck or on two decks. The term was used for ships too small to stand in the line of battle. In the late 19th century, the frigate was a type of ironclad warship that for a time was the most powerful type of vessel afloat. The term frigate was used because such ships still mounted their principal armaments on a continuous upper deck. Ship classes dubbed frigates have more closely resembled corvettes, destroyers, cruisers. The rank frigate captain derives from the name of type of ship. The term frigate originated in the Mediterranean in the late 15th century, referring to a lighter galleass type ship with oars, sails and a light armament, built for speed and maneuverability. The etymology of the word is unknown, although it may have originated as a corruption of aphractus, aphractus was, in turn, derived from the Ancient Greek phrase ἄφρακτος ναῦς, or undefended ship. In 1583, during the Eighty Years War, Habsburg Spain recovered the Southern Netherlands from the rebellious Dutch and this soon led to the occupied ports being used as bases for privateers, the Dunkirkers, to attack the shipping of the Dutch and their allies. To achieve this they developed small, maneuverable, sailing vessels that came to be referred to as frigates, in French, the term frigate became a verb, meaning to build long and low, and an adjective, adding further confusion. Even the huge English Sovereign of the Seas could be described as a frigate by a contemporary after her upper decks were reduced in 1651. The navy of the Dutch Republic was the first navy to build the larger ocean-going frigates, the first two tasks required speed, shallowness of draft for the shallow waters around the Netherlands, and the ability to carry sufficient supplies to maintain a blockade. The third task required heavy armament, sufficient to fight against the Spanish fleet, the first of these larger battle-capable frigates were built around 1600 at Hoorn in Holland. The effectiveness of the Dutch frigates became most visible in the Battle of the Downs in 1639, encouraging most other navies, especially the English, to adopt similar designs. The fleets built by the Commonwealth of England in the 1650s generally consisted of ships described as frigates, the largest of which were two-decker great frigates of the third rate. Carrying 60 guns, these vessels were as big and capable as great ships of the time, however, most other frigates at the time were used as cruisers, independent fast ships. The term frigate implied a long hull design, which relates directly to speed and also, in turn, in Danish, the word fregat is often applied to warships carrying as few as 16 guns, such as HMS Falcon which the British classified as a sloop

Warship
–
A warship is a naval ship that is built and primarily intended for naval warfare. Usually they belong to the forces of a state. As well as being armed, warships are designed to damage and are usually faster. Unlike a merchant ship, which carries cargo, a warship typically carries weapons, ammunition. Warships usually belong to a navy, though they have also operated by individuals, cooperatives. In wartime, the distinction between warships and merchant ships is often blurred, in war, merchant ships are often armed and used as auxiliary warships, such as the Q-ships of the First World War and the armed merchant cruisers of the Second World War. Until the 17th century it was common for merchant ships to be pressed into naval service, until the threat of piracy subsided in the 19th century, it was normal practice to arm larger merchant ships such as galleons. Warships have also often used as troop carriers or supply ships. The development of catapults in the 4th century BC and the subsequent refinement of technology enabled the first fleets of artillery-equipped warships by the Hellenistic age. During late antiquity, ramming fell out of use and the galley tactics against other ships used during the Middle Ages until the late 16th century focused on boarding. Naval artillery was redeveloped in the 14th century, but cannon did not become common at sea until the guns were capable of being reloaded quickly enough to be reused in the same battle. The size of a required to carry a large number of cannons made oar-based propulsion impossible. The sailing man-of-war emerged during the 16th century, by the middle of the 17th century, warships were carrying increasing numbers of cannon on their broadsides and tactics evolved to bring each ships firepower to bear in a line of battle. The man-of-war now evolved into the ship of the line, in the 18th century, the frigate and sloop-of-war – too small to stand in the line of battle – evolved to convoy trade, scout for enemy ships and blockade enemy coasts. During the 19th century a revolution took place in the means of propulsion, naval armament. Marine steam engines were introduced, at first as an auxiliary force, the Crimean War gave a great stimulus to the development of guns. The introduction of explosive shells soon led to the introduction of iron, the first ironclad warships, the French Gloire and British Warrior, made wooden vessels obsolete. Metal soon entirely replaced wood as the material for warship construction

Destroyer
–
Before World War II, destroyers were light vessels with little endurance for unattended ocean operations, typically a number of destroyers and a single destroyer tender operated together. After the war, the advent of the missile allowed destroyers to take on the surface combatant roles previously filled by battleships. This resulted in larger and more powerful guided missile destroyers more capable of independent operation, the emergence and development of the destroyer was related to the invention of the self-propelled torpedo in the 1860s. A navy now had the potential to destroy an enemy battle fleet using steam launches to launch torpedoes. Fast boats armed with torpedoes were built and called torpedo boats, the first seagoing vessel designed to fire the self-propelled Whitehead torpedo was the 33-ton HMS Lightning in 1876. She was armed with two drop collars to launch these weapons, these were replaced in 1879 by a torpedo tube in the bow. By the 1880s, the type had evolved into small ships of 50–100 tons, in response to this new threat, more heavily gunned picket boats called catchers were built which were used to escort the battle fleet at sea. The anti-torpedo boat origin of this type of ship is retained in its name in other languages, including French, Italian, Portuguese, Czech, Greek, Dutch and, up until the Second World War, Polish. At that time, and even into World War I, the function of destroyers was to protect their own battle fleet from enemy torpedo attacks. The task of escorting merchant convoys was still in the future, an important development came with the construction of HMS Swift in 1884, later redesignated TB81. This was a torpedo boat with four 47 mm quick-firing guns. At 23.75 knots, while still not fast enough to engage torpedo boats reliably. Another forerunner of the torpedo boat destroyer was the Japanese torpedo boat Kotaka, designed to Japanese specifications and ordered from the London Yarrow shipyards in 1885, she was transported in parts to Japan, where she was assembled and launched in 1887. The 165-foot long vessel was armed with four 1-pounder quick-firing guns and six torpedo tubes, reached 19 knots, in her trials in 1889, Kotaka demonstrated that she could exceed the role of coastal defense, and was capable of accompanying larger warships on the high seas. The Yarrow shipyards, builder of the parts for the Kotaka, the first vessel designed for the explicit purpose of hunting and destroying torpedo boats was the torpedo gunboat. Essentially very small cruisers, torpedo gunboats were equipped with torpedo tubes, by the end of the 1890s torpedo gunboats were made obsolete by their more successful contemporaries, the torpedo boat destroyers, which were much faster. The first example of this was HMS Rattlesnake, designed by Nathaniel Barnaby in 1885, the gunboat was armed with torpedoes and designed for hunting and destroying smaller torpedo boats. Exactly 200 feet long and 23 feet in beam, she displaced 550 tons, built of steel, Rattlesnake was un-armoured with the exception of a 3⁄4-inch protective deck

Submarine
–
A submarine is a watercraft capable of 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 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. The noun submarine evolved as a form of submarine boat, by naval tradition, submarines are usually referred to as boats rather than as ships. Although experimental submarines had been built before, submarine design took off during the 19th century, Submarines were first widely used during World War I, and now figure in many navies large and small. Civilian uses for submarines include marine science, salvage, exploration and facility inspection, Submarines can also be modified to perform more specialized functions such as search-and-rescue missions or undersea cable repair. Submarines are also used in tourism, and for undersea archaeology, most large submarines consist of a cylindrical body with hemispherical ends and a vertical structure, usually located amidships, which houses communications and sensing devices as well as periscopes. In modern submarines, this structure is the sail in American usage, a conning tower was a feature of earlier designs, a separate pressure hull above the main body of the boat that allowed the use of shorter periscopes. There is a propeller at the rear, and various hydrodynamic control fins, smaller, deep-diving and specialty submarines may deviate significantly from this traditional layout. Submarines use diving planes and also change the amount of water, Submarines have one of the widest ranges of types and capabilities of any vessel. Submarines can work at greater depths than are survivable or practical for human divers, modern deep-diving submarines derive from the bathyscaphe, which in turn evolved from the diving bell. In 1578, the English mathematician William Bourne recorded in his book Inventions or Devises one of the first plans for an underwater navigation vehicle and its unclear whether he ever carried out his idea. The first submersible of whose construction there exists reliable information was designed and built in 1620 by Cornelis Drebbel and it was propelled by means of oars. By the mid-18th century, over a dozen patents for submarines/submersible boats had been granted in England, in 1747, Nathaniel Symons patented and built the first known working example of the use of a ballast tank for submersion. His design used leather bags that could fill with water to submerge the craft, a mechanism was used to twist the water out of the bags and cause the boat to resurface. In 1749, the Gentlemens Magazine reported that a design had initially been proposed by Giovanni Borelli in 1680. By this point of development, further improvement in design stagnated for over a century, until new industrial technologies for propulsion. The first military submarine was the Turtle, a hand-powered acorn-shaped device designed by the American David Bushnell to accommodate a single person and it was the first verified submarine capable of independent underwater operation and movement, and the first to use screws for propulsion

Battleship
–
A battleship is a large armored warship with a main battery consisting of large caliber guns. During the late 19th and early 20th centuries the battleship was the most powerful type of warship, the word battleship was coined around 1794 and is a contraction of the phrase line-of-battle ship, the dominant wooden warship during the Age of Sail. The term came into use in the late 1880s to describe a type of ironclad warship. In 1906, the commissioning of HMS Dreadnought heralded a revolution in battleship design, subsequent battleship designs, influenced by HMS Dreadnought, were referred to as dreadnoughts. Battleships were a symbol of naval dominance and national might, the launch of Dreadnought in 1906 commenced a new naval arms race. Jutland was the largest naval battle and the only full-scale clash of battleships in the war, the Naval Treaties of the 1920s and 1930s limited the number of battleships, though technical innovation in battleship design continued. The value of the battleship has been questioned, even during their heyday, there were few of the decisive fleet battles that battleship proponents expected, and used to justify the vast resources spent on building battlefleets. Battleships were retained by the United States Navy into the Cold War for fire support purposes before being stricken from the U. S. Naval Vessel Register in the 2000s. A ship of the line was a large, unarmored wooden sailing ship which mounted a battery of up to 120 smoothbore guns, from 1794, the alternative term line of battle ship was contracted to battle ship or battleship. The sheer number of guns fired broadside meant a sail battleship could wreck any wooden enemy, holing her hull, knocking down masts, wrecking her rigging, and killing her crew. However, the range of the guns was as little as a few hundred yards. The first major change to the ship of the concept was the introduction of steam power as an auxiliary propulsion system. Steam power was introduced to the navy in the first half of the 19th century, initially for small craft. The French Navy introduced steam to the line of battle with the 90-gun Napoléon in 1850—the first true steam battleship, Napoléon was armed as a conventional ship-of-the-line, but her steam engines could give her a speed of 12 knots, regardless of the wind condition. This was a decisive advantage in a naval engagement. The introduction of steam accelerated the growth in size of battleships, the adoption of steam power was only one of a number of technological advances which revolutionized warship design in the 19th century. The ship of the line was overtaken by the ironclad, powered by steam, protected by metal armor, and armed with guns firing high-explosive shells. In the Crimean War, six ships and two frigates of the Russian Black Sea Fleet destroyed seven Turkish frigates and three corvettes with explosive shells at the Battle of Sinop in 1853

Aircraft carrier
–
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 ship of a fleet, as it allows a naval force to project air power worldwide without depending on local bases for staging aircraft operations. Aircraft carriers are expensive to build and are critical assets, there is no single definition of an aircraft carrier, and modern navies use several variants of the type. These variants are sometimes categorized as sub-types of aircraft carriers, Aircraft carriers may be classified according to the type of aircraft they carry and their operational assignments. Admiral Sir Mark Stanhope, former head of the Royal Navy, has said, To put it simply, as of April 2017, there are 37 active aircraft carriers in the world within twelve navies. The United States Navy has 10 large nuclear-powered fleet carriers, the largest carriers in the world, the Royal Navy of Great Britain is building two 280-m / 920-ft carriers, the Queen Elizabeth, and the Prince of Wales scheduled to go into service in 2020-2023. These are the largest carriers capable of fast speeds, by comparison, escort carriers were developed to provide defense for convoys of ships. They were smaller and slower with lower numbers of aircraft carried, most were built from mercantile hulls or, in the case of merchant aircraft carriers, were bulk cargo ships with a flight deck added on top. Light aircraft carriers were fast enough to operate with the main fleet, three nations currently operate carriers of this type, ten by the United States, and one each by France and Brazil for a total of twelve in service. Short take-off but arrested-recovery, these carriers are generally limited to carrying lighter fixed-wing aircraft with more limited payloads, currently, Russia, China, and India possess commissioned carriers of this type. Short take-off vertical-landing, limited to carrying STOVL aircraft and this type of aircraft carrier is currently in service with Italy. Some also count the nine US amphibious assault ships in their secondary light carrier role boosting the total to thirteen. Helicopter carrier, Helicopter carriers have an appearance to other aircraft carriers. Some are designed for addition of, or may include, a ski jump ramp allowing for STOVL operations or may have a ski jump installed before retirement of STOVL aircraft. In the past, some conventional carriers were converted and called commando carriers by the Royal Navy, some helicopter carriers with a resistant flight surface can operate STOVL jets. Currently the majority of carriers, but not all, are classified as amphibious assault ships. The US has nine of this type, France and Japan three, Australia two, the UK one, the Republic of Korea one and Spain one, the US and Spains amphibious assault ships operate STOVL jets in normal deployment. Supercarrier Fleet carrier Light aircraft carrier Escort carrier Several systems of identification symbol for aircraft carriers, two months later, on 18 January 1911, Ely landed his Curtiss pusher airplane on a platform on the armored cruiser USS Pennsylvania anchored in San Francisco Bay
