QF 6-pounder Hotchkiss The Ordnance QF Hotchkiss 6 pounder gun Mk I and Mk II or QF 6 pounder 8 cwt were a family of long-lived light 57 mm naval guns introduced in 1885 to defend against new, small and fast vessels such as torpedo boats and later submarines. There were many variants produced, often under license which ranged in length from 40 to 58 calibers, but 40 caliber was the most common version.

Submarine A submarine (or simply sub) 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 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. The noun "submarine" evolved as a shortened form of "submarine boat"; by naval tradition, submarines are usually referred to as "boats" rather than as "ships", regardless of their size ("boat" is usually reserved for seagoing vessels of relatively small size).

Post ship Post ship was a designation used in the Royal Navy during the second half of the 18th century and the Napoleonic Wars to describe a ship of the sixth rate (see rating system of the Royal Navy) that was smaller than a frigate (in practice, carrying fewer than 28 guns), but by virtue of being a rated ship (with at least 20 guns), had to have as its captain a post captain rather than a lieutenant or commander. Thus ships with 20 to 26 guns were post ships, though this situation changed after 1817.

Hulk (ship type) A hulk is a ship that is afloat, but incapable of going to sea. Although sometimes used to describe a ship that has been launched but not completed, the term most often refers to an old ship that has had its rigging or internal equipment removed, retaining only its flotational qualities. The word "hulk" is also used as a verb: a ship is "hulked" to convert it to a hulk. The verb was also applied to crews of Royal Navy ships in dock, who were sent to the receiving ship for accommodation, or "hulked".

Naval gunfire support Naval gunfire support (NGFS) (also known as shore bombardment) is the use of naval artillery to provide fire support for amphibious assault and other troops operating within their range. NGFS is one of a number of disciplines encompassed by the term "Naval Fires". Modern naval gunfire support is one of the three main components of amphibious warfare assault operations support, along with aircraft and ship-launched land-attack missiles. Shipborne guns have been used against shore defences since the early days of naval warfare.

QF 13-pounder 6 cwt AA gun The Ordnance QF 13 pounder Mk III anti-aircraft gun, also known as 13 pounder 6 cwt, was an early British improvisation in World War I to adapt the 13 pounder field gun to anti-aircraft use. 6 cwt referred to the weight of barrel and breech (6 × 112 lb = 672 lb) to differentiate it from other "13 pounder" guns.

Cambridge Battery Cambridge Battery (Maltese: "Batterija ta' Cambridge" ) is a Victorian-era battery in Sliema, Malta. It is commonly referred to as Fort Cambridge (Maltese: "Forti Cambridge" ), although it was never classified as a fort while in use. It originally contained an Armstrong 100-ton gun.

Target ship A target ship is a vessel — typically an obsolete or captured warship — used as a seaborne target for naval gunnery practice or for weapons testing. Targets may be used with the intention of testing effectiveness of specific types of ammunition; or the target ship may be used for an extended period of routine target practice with specialized non-explosive ammunition. The potential consequences of a drifting wreck require careful preparation of the target ship to prevent pollution, or a floating or submerged collision risk for maritime navigation.

BL 4 inch naval gun Mk VII The BL 4-inch gun Mk VII was a British high-velocity naval gun introduced in 1908 as an anti-torpedo boat gun in large ships, and in the main armament of smaller ships. Of the 600 produced, 482 were still available in 1939 for use as coastal artillery and as a defensive weapon on Defensively Equipped Merchant Ships (DEMS) during the Second World War.

Attack transport Attack transport is a United States Navy ship classification for a variant of ocean-going troopship adapted to transporting invasion forces ashore. Unlike standard troopships – often drafted from commercial shipping fleets – that rely on either a quay or tenders, attack transports carry their own fleet of landing craft.

Sixth-rate Sixth-rate was the designation used by the Royal Navy for small warships mounting between 20 and 24 carriage-mounted guns on a single deck, sometimes with smaller guns on the upper works and sometimes without. It thus encompassed ships with up to 30 guns in all. In the first half of the 18th century the main battery guns were 6-pounders, but by mid-century these were supplanted by 9-pounders.

German ocean-going torpedo boats of World War I The first German Naval Law of 1898 legislated the construction of an ocean-going battle fleet by Imperial Germany. To accompany the squadrons of battleships and cruisers, the law called for the construction of flotillas of large torpedo-boats ("große Torpedoboote"), considerably larger, better armed and more seaworthy than the previous torpedo boats built by Germany.

Naval ship A naval ship is a military ship (or sometimes boat, depending on classification) used by a navy. Naval ships are differentiated from civilian ships by construction and purpose. Generally, naval ships are damage resilient and armed with weapon systems, though armament on troop transports is light or non-existent.

Mine planter (U.S. Army) Mine planter and the earlier "torpedo planter" was a term used for mine warfare ships into the early days of World War I. In later terminology, particularly in the United States, a mine planter was a ship specifically designed to install controlled mines or contact mines in coastal fortifications. This type of ship diverged in both function and design from a ship operating as a naval minelayer. Though the vessel may be seagoing it is not designed to lay large numbers of mines in open sea. A mine planter was designed to place controlled minefields in exact locations so that they might be fired individually or as a group from shore when observers noted a target to be at or near a designated mine's position. The terms and types of specialized ship existed from the 1860s where "torpedoes" were made famous in the American Civil War until the demise of large, fixed coastal fortifications brought on by the changes of World War II.

HNoMS Lyn (1882) HNoMS "Lyn" - or just "Lyn" in Norwegian - was the lead ship of a class of 27 torpedo boats built between 1892 and 1912. The name means "Lightning". By modern standards, she was extremely lightly armed with just one 'quick fire' 37 mm cannon and a single, fixed torpedo tube, but in her time she did pack a punch. Later boats of her class carried heavier armament. "Lyn" was later renamed "Od", before she and most of her class were scrapped in 1920, long after they were obsolete.

Planned Australian offshore combatant vessel The Offshore Combatant Vessel (OCV) is a proposed multipurpose small warship class for the Royal Australian Navy (RAN). Initially proposed in the and marked as procurement project SEA 1180, the 20 OCVs would replace 26 vessels across four separate ship classes: the "Armidale"-class patrol boat s, the "Huon"-class minehunter s, the "Leeuwin"-class survey vessel s, and the "Paluma"-class survey motor launch es. Although having a common design (which could be up to 2,000 tonnes in displacement), the ships would use a modular mission payload system to fulfil specific roles; primarily border patrol, mine warfare, and hydrographic survey. The 2013 Defence White Paper committed to the OCV project as a long-term goal, but opted in the short term for an accelerated procurement of an existing design to replace the "Armidale"s, and life-extension refits for the other types.

HMS Hood (1891) HMS "Hood" was a modified "Royal Sovereign"-class pre-dreadnought battleship built for the Royal Navy in the early 1890s. She differed from the other ships of the class in that she had cylindrical gun turrets instead of barbettes and a lower freeboard. She served most of her active career in the Mediterranean Sea, where her low freeboard was less of a disadvantage. The ship was placed in reserve in 1907 and later became the receiving ship at Queenstown, Ireland. "Hood" was used in the development of anti-torpedo bulges in 1913 and was scuttled in late 1914 to act as a blockship across the southern entrance of Portland Harbour after the start of World War I.

MAS (motorboat) Motoscafo armato silurante (Italian: "torpedo armed motorboat"), commonly abbreviated as MAS was a class of fast torpedo armed vessel used by the "Regia Marina" (the Royal Navy of Italy) during World War I and World War II. Originally, "MAS" referred to "motobarca armata SVAN" ("armed motorboat SVAN"), where "SVAN" stood for "Società Veneziana Automobili Navali" ("Naval Automobile Society of Venice).

HMS Black Prince (1861) HMS "Black Prince" was the third ship of that name to serve with the Royal Navy. She was the world's second ocean-going, iron-hulled, armoured warship, following her sister ship, HMS "Warrior" . For a brief period the two "Warrior"-class ironclad s were the most powerful warships in the world, being virtually impregnable to the naval guns of the time. Rapid advances in naval technology left "Black Prince" and her sister obsolete within a short time, however, and she spent more time in reserve and training roles than in first-line service.

United States naval gunfire support debate The United States naval gunfire support debate is an ongoing debate among the United States Navy, Marine Corps, Congress, and independent groups like the "United States Naval Gunfire Support Association" over what role naval gunfire support and naval surface fire support (NSFS) should play within the navy and how such a role can best be provided. At the heart of the issue is the role that naval gunfire support—the use of naval artillery to provide fire support for amphibious assault and other troops operating within their range—should play in the U.S. Navy of the 21st century.

Torpedo gunboat In late 19th-century naval terminology, torpedo gunboats were a form of gunboat armed with torpedoes and designed for hunting and destroying smaller torpedo boats. By the end of the 1890s torpedo gunboats were superseded by their more successful contemporaries, the torpedo boat destroyers.

Vickers machine gun The Vickers machine gun or Vickers gun is a name primarily used to refer to the water-cooled .303 British (7.7 mm) machine gun produced by Vickers Limited, originally for the British Army. The machine gun typically required a six to eight-man team to operate: one fired, one fed the ammunition, the rest helped to carry the weapon, its ammunition, and spare parts. It was in service from before the First World War until the 1960s, with air-cooled versions of it on many Allied World War I fighter aircraft.
