The battlecruiser was a type of capital ship of the first half of the 20th century. These were similar in displacement, armament and cost to battleships, but differed in form and balance of attributes. Battlecruisers typically had thinner armour and a somewhat lighter main gun battery than contemporary battleships, installed on a longer hull with much higher engine power in order to attain greater speeds. The first battlecruisers were designed in the United Kingdom, as a development of the armoured cruiser, at the same time as the dreadnought succeeded the pre-dreadnought battleship. The goal of the design was to outrun any ship with similar armament, and chase down any ship with lesser armament; they were intended to hunt down slower, older armoured cruisers and destroy them with heavy gunfire while avoiding combat with the more powerful but slower battleships. However, as more and more battlecruisers were built, they were increasingly used alongside the better-protected battleships.
The United States Navy, United States Coast Guard, and United States National Oceanic and Atmospheric Administration (NOAA) use a hull classification symbol to identify their ships by type and by individual ship within a type. The system is analogous to the pennant number system that the Royal Navy and other European and Commonwealth navies use.
The Kriegsmarine was the navy of Nazi Germany from 1935 to 1945. It superseded the Imperial German Navy of the German Empire (1871–1918) and the inter-war Reichsmarine (1919–1935) of the Weimar Republic. The Kriegsmarine was one of three official branches, along with the Heer and the Luftwaffe of the Wehrmacht, the German armed forces from 1935 to 1945.
A torpedo boat is a relatively small and fast naval ship designed to carry torpedoes into battle. The first designs were steam-powered craft dedicated to ramming enemy ships with explosive spar torpedoes. Later evolutions launched variants of self-propelled Whitehead torpedoes.
A naval ship is a military ship 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.
A light cruiser is a type of small or medium sized warship. The term is a shortening of the phrase "light armored cruiser", describing a small ship that carried armor in the same way as an armored cruiser: a protective belt and deck. Prior to this smaller cruisers had been of the protected cruiser model, possessing armored decks only. While lighter and smaller than other contemporary ships they were still true cruisers, retaining the extended radius of action and self-sufficiency to act independently across the world. Through their history they served in a variety of roles, primarily as convoy escorts and destroyer command ships, but also as scouts and fleet support vessels for battle fleets.
A fast attack craft (FAC) is a small, fast, agile and offensive warship armed with anti-ship missiles, gun or torpedoes. FACs are usually operated in close proximity to land as they lack both the seakeeping and all-round defensive capabilities to survive in blue water. The size of the vessel also limits the fuel, stores and water supplies. In size they are usually between 50–800 tonnes and can reach speeds of 25–50 knots (46–93 km/h).
The Type 143A Gepard class was a class of missile bearing fast attack craft and the last one in service with the German Navy before the remaining four operational ships were decommissioned on 16 November 2016. The Ghana Navy operates two such ships.
SMS Seeadler was an unprotected cruiser of the Bussard class, the third member of a class of six ships built by the German Kaiserliche Marine. Her sister ships included Bussard, the lead ship, along with Falke, Condor, Cormoran, and Geier. Seeadler was built at the Kaiserliche Werft in Danzig in late 1890, launched in February 1892, and commissioned in August of that year. Intended for colonial service, Seeadler was armed with a main battery of eight 10.5-centimeter (4.1 in) guns and had a top speed of 15.5 knots.
The La Combattante IIa fast attack craft is a class of fast attack craft originally built for the German Navy as Type 148 Tiger-class fast attack craft. They were later transferred to the Hellenic Navy and the class was renamed Combattante IIa, as with similar French made ships. All the ships were under mid-life updates in 1980s. Two vessels in the class, P-74 and P-75, were fitted with RGM-84 Harpoon anti-ship missiles and a new ESM was fitted after transfer.
The La Combattante III type missile boats of the Hellenic Navy are a class of four fast attack craft ordered by Greece in September 1974 from France. The vessels had no class name but are referred to by type. They are similar to the La Combattante IIa-class fast attack craft already in service, but are larger and armed with torpedoes. A second group of six were ordered in 1978, to be built under license in Greece and use Penguin Mk 2 Mod 3 missiles. Since 2019, all the ships of the class use Harpoon anti-ship missiles.
An unprotected cruiser was a type of naval warship in use during the late Victorian or pre-dreadnought era. The name was meant to distinguish these ships from “protected cruisers” which had become accepted in the 1880s. A protected cruiser did not have side armor on its hull like a battleship or “armored cruiser” but had only a curved armored deck built inside the ship – like an internal turtle shell – which prevented enemy fire penetrating through the ship down into the most critical areas such as machinery, boilers, and ammunition storage. An unprotected cruiser lacked even this level of internal protection. The definitions had some gray areas because individual ships could be built with a protective deck that did not cover more than a small area of the ship, or was so thin as to be of little value. An unprotected cruiser was generally cheaper and less effective than a protected cruiser, while a protected cruiser was generally cheaper and less effective than an armored cruiser.
SMS Bussard was an unprotected cruiser of the Imperial German Navy, built in the 1880s. She was the lead ship of her class, which included five other vessels. The cruiser's keel was laid in 1888, and she was launched in January 1890 and commissioned in October of that year. Intended for overseas duty, Bussard was armed with a main battery of eight 10.5-centimeter (4.1 in) guns, and could steam at a speed of 15.5 knots.
The Bussard class of unprotected cruisers were built for the German Kaiserliche Marine in the late 1880s and early 1890s. The class comprised six ships: Bussard, the lead ship, Falke, Seeadler, Cormoran, Condor, and Geier. Designed for service in Germany's colonial empire, the class emphasized a long-range cruising radius and relatively heavy armament; they were also the last cruisers in the Kaiserliche Marine to be equipped with an auxiliary sailing rig. The ships were equipped with eight 10.5-centimeter (4.1 in) guns.
