Motor torpedo boatA motor torpedo boat is a fast torpedo boat, especially of the mid 20th century. The motor in the designation originally referred to their use of petrol engines, typically marinised aircraft engines or their derivatives, which distinguished them from other naval craft of the era, including other torpedo boats, that used steam turbines or reciprocating steam engines. Later, diesel-powered torpedo boats appeared, in turn or retroactively referred to as "motor torpedo boats" for their internal combustion engines, as distinct from steam powered reciprocating or turbine propulsion.
Scout cruiserA scout cruiser was a type of warship of the early 20th century, which were smaller, faster, more lightly armed and armoured than protected cruisers or light cruisers, but larger than contemporary destroyers. Intended for fleet scouting duties and acting as a flotilla leader, a scout cruiser was typically armed with six to ten destroyer-type guns of 3-inch (76 mm) to 4.7-inch (120 mm) calibre, plus two to four torpedo tubes.
KronstadtKronstadt (Kronshtadt, krɐnˈʂtat) is a Russian port city in Kronshtadtsky District of the federal city of Saint Petersburg, located on Kotlin Island, west of Saint Petersburg, near the head of the Gulf of Finland. It is linked to the former Russian capital by a combination levee-causeway-seagate, the St Petersburg Dam, part of the city's flood defences, which also acts as road access to Kotlin island from the mainland.
Ship classA ship class is a group of ships of a similar design. This is distinct from a ship type, which might reflect a similarity of tonnage or intended use. For example, is a nuclear aircraft carrier (ship type) of the (ship class). In the course of building a class of ships, design changes might be implemented. In such a case, the ships of different design might not be considered of the same class; each variation would either be its own class, or a subclass of the original class (see for an example).
Water-tube boilerA high pressure watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which boils water in the steam-generating tubes. In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled tubes that make up the walls of the furnace to generate steam. The heated water/steam mixture then rises into the steam drum.
Chilean NavyThe Chilean Navy (Armada de Chile) is the naval warfare service branch of the Chilean Armed Forces. It is under the Ministry of National Defense. Its headquarters are at Edificio Armada de Chile, Valparaiso. Maritime history of Chile First Chilean Navy Squadron The origins of the Chilean Navy date back to 1817, when General Bernardo O'Higgins prophetically declared after the Chilean victory at the Battle of Chacabuco that a hundred such victories would count for nothing if Chile did not gain control of the sea.
AvisoAn aviso was originally a kind of dispatch boat or "advice boat", carrying orders before the development of effective remote communication. The term, derived from the Portuguese and Spanish word for "advice", "notice" or "warning", an aviso, was later adopted by the French and Portuguese navies to classify their medium-sized warships designed for colonial service. The term continued to be used in the French Navy to classify the patrol frigates until 2012, when the remaining ships of the class were reclassified as offshore patrol ships.
Royal Netherlands NavyThe Royal Netherlands Navy (Koninklijke Marine) is the naval force of the Kingdom of the Netherlands. It is one of the four Netherlands Armed Forces. It was founded on 8 January 1488, making it the third oldest naval force in the world. During the 17th century, the navy of the Dutch Republic (1581–1795) was one of the most powerful naval forces in the world and played an active role in the Anglo-Dutch Wars, the Franco-Dutch War, and wars against Spain and several other European powers.
Limbo (weapon)Limbo, or Anti Submarine Mortar Mark 10 (A/S Mk.10), was the final development of the forward-throwing anti-submarine weapon Squid, designed during the Second World War and was developed by the Admiralty Underwater Weapons Establishment in the 1950s. Limbo was installed on the quarterdeck of Royal Navy escort ships from 1955 to the mid-1980s, Australian-built destroyer and s. Limbo was widely employed by the Royal Canadian Navy, being incorporated into all destroyer designs from the late 1950s to the early 1970s, including the , , , and classes and the Type 12 President Class frigates built for the South African Navy in the 1960s.
Polish NavyThe Polish Navy (; often abbreviated to Marynarka) is the naval branch of the Polish Armed Forces. The Polish Navy consists of 46 ships and about 12,000 commissioned and enlisted personnel. The traditional ship prefix in the Polish Navy is ORP (Okręt Rzeczypospolitej Polskiej, "Warship of the Republic of Poland"). Polish–Lithuanian Commonwealth Navy The Polish Navy has its roots in naval vessels that were largely employed on Poland's main rivers in defense of trade and commerce.
