A warship or combatant ship is a ship that is used for naval warfare. Usually they belong to the navy branch of the armed forces of a nation, though they have also been operated by individuals, cooperatives and corporations. As well as being armed, warships are designed to withstand damage and are typically faster and more maneuverable than merchant ships. Unlike a merchant ship, which carries cargo, a warship typically carries only weapons, ammunition and supplies for its crew.
During the 18th and 19th centuries, a sloop-of-war was a warship of the British Royal Navy with a single gun deck that carried up to 18 guns. The rating system of the Royal Navy covered all vessels with 20 or more guns; thus, the term encompassed all unrated warships, including gun-brigs and cutters. In technical terms, even the more specialised bomb vessels and fire ships were classed by the Royal Navy as sloops-of-war, and in practice these were employed in the role of a sloop-of-war when not carrying out their specialised functions.
The Hellenic Navy is the naval force of Greece, part of the Hellenic Armed Forces. The modern Greek navy historically hails from the naval forces of various Aegean Islands, which fought in the Greek War of Independence. During the periods of monarchy it was known as the Royal Hellenic Navy.
Steam frigates and the smaller steam corvettes, steam sloops, steam gunboats and steam schooners, were steam-powered warships that were not meant to stand in the line of battle. The first such ships were paddle steamers. Later on the invention of screw propulsion enabled construction of screw-powered versions of the traditional frigates, corvettes, sloops and gunboats.
A screw sloop is a propeller-driven sloop-of-war. They were popularized in the mid-19th century, during the introduction of the steam engine and the transition of fleets to this new technology.
Artemis is the ancient Greek goddess of the hunt, the wilderness, wild animals, the Moon, and chastity.
Odin is the chief god of the Norse pantheon.
In the Royal Navy and other navies of Europe and the Commonwealth of Nations, ships are identified by pennant number. Historically, naval ships flew a flag that identified a flotilla or type of vessel. For example, the Royal Navy used a red burgee for torpedo boats and a pennant with an H for torpedo boat destroyers. Adding a number to the type-identifying flag uniquely identified each ship.
A unicorn is a legendary horse-like beast with a horn on its forehead.
Eight vessels of the Royal Navy have been named HMS Acheron after Acheron, a river of Hades in Greek mythology.
Seven ships of the Royal Navy have borne the name HMS Hydra, after the Lernaean Hydra of Greek mythology:
The Hydra class were a class of three paddlewheel steam sloops of the British Royal Navy. They saw active service variously in the Baltic during the Crimean War, against Ottoman forces in Syria and against slavers in West Africa. Latterly, Hydra and Hecate were used for surveys in the Mediterranean, the Pacific, Australia and the Atlantic, and thus their names were re-used for the Hecla-class survey vessels in the late 20th century. Two of the classes were broken up after more than twenty-five years of service, and Hecla was sold for commercial use in 1863.
