Azopardo-class Frigate
The ''Azopardo''-class frigates were a class of two post-World War II warships, designed and built in Argentina in 1940-1959, originally as part of a class of four large minelayers (see ''Murature''-class ships). They were in service with the Argentine Navy from the mid-1950s to 1972. The class was named after Juan Bautista Azopardo, an Argentine naval officer in the Independence and Cisplatine wars. Design The class was as part of a program to build four mine warfare ships during the Second World War, of which two (''Murature'' and ''King'') were completed as patrol ships in the 1940s and the others (''Piedrabuena'' and ''Azopardo'') as antisubmarine frigates in the 1950s. The ''Azopardo'' class frigates had a metal hull with a single mast and funnel. They were powered by two Parsons steam turbines fed by two water-tube boilers, driving two propellers. The main battery was composed of four Bofors DP guns, with a secondary battery of four Bofors Anti-Aircraft guns in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Second World War
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the World War II by country, vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies of World War II, Allies and the Axis powers. World War II was a total war that directly involved more than 100 million Military personnel, personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Air warfare of World War II, Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the Atomic bombings of Hiroshima and Nagasaki, only two nuclear weapons ever used in war. World War II was by far the List of wars by death toll, deadliest conflict in hu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frigates Of Argentina
A frigate () is a type of warship. In different eras, the roles and capabilities of ships classified as frigates have varied somewhat. The name frigate in the 17th to early 18th centuries was given to any full-rigged ship built for speed and maneuverability, intended to be used in scouting, escort and patrol roles. The term was applied loosely to ships varying greatly in design. In the second quarter of the 18th century, the 'true frigate' was developed in France. This type of vessel was characterised by possessing only one armed deck, with an unarmed deck below it used for berthing the crew. Late in the 19th century (British and French prototypes were constructed in 1858), armoured frigates were developed as powerful ironclad warships, the term frigate was used because of their single gun deck. Later developments in ironclad ships rendered the frigate designation obsolete and the term fell out of favour. During the Second World War the name 'frigate' was reintroduced to de ...

List Of Ships Of The Argentine Navy
This list includes all major warships that entered service with the Argentine Navy since being formally established in the 1860s.In 1861 the modern Argentine Republic was born, after the Battle of Pavón. It also includes ships that were purchased by Argentina but did not enter service under Argentine flag. The list does not include vessels prior to the 1860s; and it also excludes auxiliary ships (tugs, transports, colliers, tankers, scientific vessels, etc.) which are listed separately. In addition, there is a separate list of ships currently in service with the Argentine Navy, regardless the type. The list is organized by type of ship, by class within each type, and by entry date within each class. Service entry dates indicate the ship's commissioning into the Argentine Navy, and not the ship's entry in service with another navy unless specifically said. Naming tradition The current norms establish naming conventions for Argentine Navy ships according to their type, s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ARA Piedra Buena (P-36)
ARA Piedra Buena is a World War II era Argentine Navy warship, originally classified as patrol boat and later as antisubmarine frigate. The vessel is named after Luis Piedrabuena, an Argentine mariner (later naval officer) that explored and guarded Argentine sovereignty in Patagonia. It is the third Argentine naval ship with this name. Design ''Piedra Buena'' was as part of a program to build four mine warfare and patrol ships during the Second World War, of which two (''Murature'' and ''King'') were completed as patrol boats and the others (''Piedrabuena'' and ''Azopardo'') as antisubmarine frigates. History ''Piedra Buena'' was ordered in 1943, however significant delays caused it to be launched in 1954 and completed four years later. Initially she was named ''Piedrabuena'' by decree 23.388/49 and classified as a patrol ship, however her name was amended to ''Piedra Buena'' and reclassified as a frigate by decree 11.373/58. Between 1959 and 1968 she belonged to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Main Battery
A main battery is the primary weapon or group of weapons around which a warship is designed. As such, a main battery was historically a gun or group of guns, as in the broadsides of cannon on a ship of the line. Later, this came to be turreted groups of similar large-caliber naval rifles. With the evolution of technology the term has come to encompass guided missiles as a vessel's principal offensive weapon, deployed both on surface ships and submarines. A main battery features common parts, ammunition, and fire control across the weapons which it comprises. Description In the age of cannon at sea, the main battery was the principal group of weapons around which a ship was designed, usually its heavies. With the coming of naval rifles and subsequent revolving gun turrets, the main battery became the principal group of heaviest guns, regardless of how many turrets they were placed in. As missiles displaced guns both above and below the water their principal group became ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Water-tube Boiler
A 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. Here, saturated steam is drawn off the top of the drum. In some services, the steam passes through tubes in the hot gas path, (a superheater) to become superheated. Superheated steam is defined as steam that is heated above the boiling point at a given pressure. Superheated steam is a dry gas and therefore is typically used to drive turbines, since water droplets can severely damage turbine blades. Saturated water at the bottom of the steam drum returns to the lower drum ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steam Turbine
A steam turbine is a machine that extracts thermal energy from pressurized steam and uses it to do mechanical work on a rotating output shaft. Its modern manifestation was invented by Charles Parsons in 1884. Fabrication of a modern steam turbine involves advanced metalwork to form high-grade steel alloys into precision parts using technologies that first became available in the 20th century; continued advances in durability and efficiency of steam turbines remains central to the energy economics of the 21st century. The steam turbine is a form of heat engine that derives much of its improvement in thermodynamic efficiency from the use of multiple stages in the expansion of the steam, which results in a closer approach to the ideal reversible expansion process. Because the turbine generates rotary motion, it can be coupled to a generator to harness its motion into electricity. Such turbogenerators are the core of thermal power stations which can be fueled by fossil- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
