Andrea Doria-class Cruiser
The ''Andrea Doria'' class were helicopter cruisers of the Italian Navy. Italy's first major new designs of the post–World War II era, these ships were primarily designed for anti-submarine warfare tasks. Initially planned for three ships, the two ships that were constructed, and served until 1991 in both active and training capacities. The ''Andrea Doria'' class formed the basis for the larger that followed them. Design Ordered in the 1957-58 Naval Programme, the ''Andrea Doria'' class were designed to operate the RIM-2 Terrier surface-to-air missile (SAM) system and Sikorsky SH-3 Sea King helicopters as both a platform for anti-air and anti-submarine warfare. The hull was based on the , with a length of and an enlarged beam to allow for the installation of a flight deck and hangar, measuring . The vessels had a draught of and displaced 5,000 tons standard and 6,500 tons loaded.Gardiner and Chumbly, p.204-205 The flight deck measured and was placed aft of the ...

Helicopter Cruiser
The aircraft cruiser (also known as aviation cruiser or cruiser-carrier) is a warship that combines the features of the aircraft carrier and a surface warship such as a cruiser or battleship. Early types The first aircraft cruiser was originally a 1930s experimental concept of creating an all-around warship. The early aircraft cruisers were usually armed with relatively heavy artillery, mines and a number of aircraft fitted with floats (making the ship a kind of seaplane tender/ fighter catapult ship). The early aircraft cruiser turned out to be an unsuccessful design. The rapid development of naval aircraft in the 1930s quickly rendered the vessels obsolete, and they were rebuilt e.g. as anti-aircraft cruisers. A United States design for a flight deck cruiser from 1930,Friedman 1983, p.179. was described as "a light cruiser forwards ndone half of a aft". Although not built, similar ships were created during and after World War II as reconstructions and later from the kee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surface-to-air Missile
A surface-to-air missile (SAM), also known as a ground-to-air missile (GTAM) or surface-to-air guided weapon (SAGW), is a missile designed to be launched from the ground to destroy aircraft or other missiles. It is one type of anti-aircraft system; in modern armed forces, missiles have replaced most other forms of dedicated anti-aircraft weapons, with anti-aircraft guns pushed into specialized roles. The first attempt at SAM development took place during World War II, but no operational systems were introduced. Further development in the 1940s and 1950s led to operational systems being introduced by most major forces during the second half of the 1950s. Smaller systems, suitable for close-range work, evolved through the 1960s and 1970s, to modern systems that are man-portable. Shipborne systems followed the evolution of land-based models, starting with long-range weapons and steadily evolving toward smaller designs to provide a layered defence. This evolution of design increasin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Castellammare Di Stabia
Castellammare di Stabia (; nap, Castiellammare 'e Stabbia) is a ''comune'' in the Metropolitan City of Naples, Campania region, in southern Italy. It is situated on the Bay of Naples about southeast of Naples, on the route to Sorrento. History Castellammare di Stabia lies next to the ancient Roman city of Stabiae, which was destroyed by the eruption of Mount Vesuvius in AD 79. The castle, of the city it takes its name from, was erected around the 9th century on a hill commanding the southern side of the Gulf of Naples. It was restored during the reign of Frederick II of Hohenstaufen and enlarged by King Charles I of Anjou. The comune, previously called ''Castellamare'', assumed the name ''Castellammare'' on 22 January 1863, and the current name on 31 May 1912.

Pennant Number
In the Royal Navy and other navies of Europe and the Commonwealth of Nations, ships are identified by pennant number (an internationalisation of ''pendant number'', which it was called before 1948). 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. In the current system, a letter prefix, called a ''flag superior'', identifies the type of ship, and numerical suffix, called a flag inferior, uniquely identifies an individual ship. Not all pennant numbers have a flag superior. Royal Navy systems The Royal Navy first used pennants to distinguish its ships in 1661 with a proclamation that all of his majesty's ships must fly a union pennant. This distinction was further strengthened by a proclamation in 1674 which forbade merchant vessels from flying any penna ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bell UH-1N Twin Huey
The Bell UH-1N Twin Huey is a medium military helicopter designed and produced by the American aerospace manufacturer Bell Helicopter. It is a member of the extensive Huey family, the initial version was the CUH-1N Twin Huey (later CH-135 Twin Huey), which was first ordered by the Canadian Forces in 1968. Barely a year following initial discussions, the UH-1N performed its maiden flight in April 1969. Its procurement by the US military was initially controversial due to the high level of Canadian content, such as its Pratt & Whitney Canada PT6T turboshaft engines. However, the acquisition was approved and the Twin Huey was quickly delivered to the United States Air Force and being sent to front line combat units in Vietnam in October 1970. During the following year, the Canadian Forces, United States Marine Corps, and the United States Navy all received their first examples; Bell was also quick to adapt the Twin Huey into a civilian helicopter, the Bell 212, as well as the e ...

Mark 32 Surface Vessel Torpedo Tubes
Mark 32 Surface Vessel Torpedo Tubes (Mk 32 SVTT) is a torpedo launching system designed for the United States Navy. History The Mark 32 has been the standard anti-submarine torpedo launching system aboard United States Navy surface vessels since its introduction in 1960, and is in use aboard the warships of several other navies. During the FRAM Program, , and destroyers were modernized and fitted with two Mark 32 torpedo tubes on each side of their midship. The torpedo tubes' service extended to multiple other countries such as Mexico, South Korea, Taiwan, Turkey, Egypt and many more due to the fact that decommissioned American ships were bought or transferred over to them throughout the years, notably s. Japan uses the HOS-301 torpedo tubes which are redesignated version of the Mark 32. Design Most versions (referred to as modifications or mods) are triple-tube sets that can be rotated or trained to face a target. The exception is the Mod 9 sets, which only have tw ...

Draft (hull)
The draft or draught of a ship's hull is the vertical distance between the waterline and the bottom of the hull ( keel). The draught of the vessel is the maximum depth of any part of the vessel, including appendages such as rudders, propellers and drop keels if deployed. Draft determines the minimum depth of water a ship or boat can safely navigate. The related term air draft is the maximum height of any part of the vessel above the water. The more heavily a vessel is loaded, the deeper it sinks into the water, and the greater its draft. After construction, the shipyard creates a table showing how much water the vessel displaces based on its draft and the density of the water (salt or fresh). The draft can also be used to determine the weight of cargo on board by calculating the total displacement of water, accounting for the content of the ship's bunkers, and using Archimedes' principle. The closely related term "trim" is defined as the difference between the forward and a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beam (nautical)
The beam of a ship is its width at its widest point. The maximum beam (BMAX) is the distance between planes passing through the outer extremities of the ship, beam of the hull (BH) only includes permanently fixed parts of the hull, and beam at waterline (BWL) is the maximum width where the hull intersects the surface of the water. Generally speaking, the wider the beam of a ship (or boat), the more initial stability it has, at the expense of secondary stability in the event of a capsize, where more energy is required to right the vessel from its inverted position. A ship that heels on her ''beam ends'' has her deck beams nearly vertical. Typical values Typical length-to-beam ratios ( aspect ratios) for small sailboats are from 2:1 (dinghies to trailerable sailboats around ) to 5:1 (racing sailboats over ). Large ships have widely varying beam ratios, some as large as 20:1. Rowing shells In watercraft, a racing shell (also referred to as just a ''fine boat'' (UK) or just ' ...

Sikorsky SH-3 Sea King
The Sikorsky SH-3 Sea King (company designation S-61) is an American twin-engined anti-submarine warfare (ASW) helicopter designed and built by Sikorsky Aircraft. A landmark design, it was one of the first ASW rotorcraft to use turboshaft engines. The Sea King has its origins in efforts by the United States Navy to counter the growing threat of Soviet submarines during the 1950s. Accordingly, the helicopter was specifically developed to deliver a capable ASW platform; in particular, it combined the roles of ''hunter'' and ''killer'', which had previously been carried out by two separate helicopters. The Sea King was initially designated ''HSS-2'', which was intended to imply a level of commonality to the earlier ''HSS-1''; it was subsequently redesignated as the ''SH-3A'' during the early 1960s. Introduced to service in 1961, it was operated by the United States Navy as a key ASW and utility asset for several decades prior to being replaced by the non-amphibious Sikorsky ...
