Type 965 Radar
The Type 965 radar was VHF ( P band) long-range aircraft warning radar used by warships of the Royal Navy from the 1960s onwards. The Type 965M, Type 965P, Type 965Q and Type 965R were improved versions; the Type 960, 965M and 965Q used the single bedstead AKE(1) aerial, whilst the Type 965P and 965R used the double bedstead AKE(2) aerial. The 965 is ultimately designed to a May 1950 requirement for a further updated version of the 1945 Type 960. The 960 provided long-range early warning on small ships, but had a very wide beam at 35° horizontal. In 1954 the idea of a general-purpose frigate with the ability to provide some fighter direction arose, which required a radar with a much narrower beam. Marconi responded with the 965, reducing the beam to 12°. Based on WWII technology, the 965 was subject to considerable radar clutter from waves. The Type 965Q and 965R were improvements on the 965M and 965P respectively, adding a COHO-based moving target indication (MTI) mode to s ...

HMS Coventry (D118)
HMS ''Coventry'' was a Type 42 (''Sheffield''-class) destroyer of the Royal Navy. Laid down by Cammell Laird and Company, Limited, at Birkenhead on 29 January 1973, she was launched on 21 June 1974 and accepted into service on 20 October 1978 at a cost of £37,900,000. She was sunk by Argentine Air Force A-4 Skyhawks on 25 May 1982 during the Falklands War. Background The principal role of these ships was to provide the fleet with mid-range anti-air warfare capability with secondary roles of anti-surface and anti-submarine. A total of fourteen Type 42s were built for the Royal Navy between 1972 and 1985, in three tranches, with ''Coventry'' the last of the first tranche to be commissioned. To cut costs, the first two tranches had 47 feet removed from the bow and the beam-to-length ratio reduced. These early Type 42s performed poorly during trials and were notoriously poor sea-keepers. Type 42 destroyers were fitted with the Sea Dart surface-to-air missiles designed i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Picket Ship
A radar picket is a radar-equipped station, ship, submarine, aircraft, or vehicle used to increase the radar detection range around a nation or military (including naval) force to protect it from surprise attack, typically air attack, or from criminal activities such as smuggling. By definition a radar picket must be some distance removed from the anticipated targets to be capable of providing ''early warning''. Often several detached radar units would be placed to encircle a target to provide increased cover in all directions; another approach is to position units to form a ''barrier line''. Radar picket units may also be equipped to direct friendly aircraft to intercept any possible enemy. In British terminology the radar picket function is called aircraft direction. Airborne radar pickets are generally referred to as airborne early warning (AEW). In a sense radars intended to track ballistic missiles can be thought of as radar pickets, but because such systems are also used f ...

Ikara (missile)
The Ikara missile was an Australian ship-launched anti-submarine missile, named after an Australian Aboriginal word for "throwing stick". It launched an acoustic torpedo to a range of , allowing fast-reaction attacks against submarines at ranges that would otherwise require the launching ship to close for attack, placing itself at risk. By flying to a distant target, the engagement time was dramatically shorter than provided by short-range weapons, giving the target less time to respond. Design and development With the development of nuclear power, submarine performance, especially speed, improved dramatically, as did the threat they posed. Simultaneously, sonar detection capability at long range was also improving significantly, but only short-range weapons were available to surface escort warships. The final British development of the A/S mortar was the Limbo mortar, able to fire in all directions but limited to a maximum range of . 40kn. Text: Even the latest modern Mark 46 ...

Leander-class Frigate
The ''Leander''-class, or Type 12I (Improved) frigates,Purvis, M.K., 'Post War RN Frigate and Guided Missile Destroyer Design 1944-1969', Transactions, Royal Institution of Naval Architects (RINA), 1974 comprising twenty-six vessels, was among the most numerous and long-lived classes of frigate in the Royal Navy's modern history. The class was built in three batches between 1959 and 1973. It had an unusually high public profile, due to the popular BBC television drama series ''Warship''. The ''Leander'' silhouette became synonymous with the Royal Navy through the 1960s until the 1980s. The ''Leander'' design or derivatives of it were built for other navies: *Royal New Zealand Navy as the ''Leander'' class *Chilean Navy: *Royal Australian Navy: *Indian Navy: *Royal Netherlands Navy: Design The policy adopted by the Royal Navy during the 1950s of acquiring separate types of frigates designed for specialised roles (i.e. anti-submarine, anti-aircraft and aircraft direction ...

Tribal-class Frigate
The Type 81, or Tribal class, frigates were ordered and built as sloops to carry out similar duties to the immediate post war improved s and s in the Persian Gulf. In the mid 1960s the seven Tribals were reclassified as second class general-purpose frigates to maintain frigate numbers. After the British withdrawal from East of Suez in 1971 the Tribals operated in the NATO North Atlantic sphere with the only update the fitting of Seacat missiles to all by 1977, limited by their single propeller and low speed of 24 knots. In 1979-80 age and crew and fuel shortages saw them transferred to the stand-by squadrons; three were reactivated in 1982 during the Falklands War for training and guardship duties in the West Indies. History The Tribals were designed during the 1950s as a response to the increasing cost of single-role vessels such as the Type 14s. They were first such 'multi role' vessels for the Royal Navy. They were designed specifically with colonial 'gunboat' duties in mind ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leopard-class Frigate
The Type 41 or ''Leopard'' class were a class of anti-aircraft defence frigates built for the Royal Navy (4 ships) and Indian Navy (3 ships) in the 1950s.Purvis, M.K., 'Post War RN Frigate and Guided Missile Destroyer Design 1944-1969', Transactions, Royal Institution of Naval Architects (RINA), 1974Marriott, Leo, 'Royal Navy Frigates Since 1945', Second Edition, , Published by Ian Allan Ltd (Surrey, UK), 1990 The Type 41, together with the Type 61 variant introduced diesel propulsion into the Royal Navy, the perceived benefits being long range, low fuel use, reduced crew (especially skilled artificers), and reduced complexity. Although successful, improvements in traditional steam turbine technology erased the fuel economy advantage of the diesel powerplants and led to production being curtailed in favour of the Type 12 frigate, which was similar in overall design.

HMS Ark Royal (R09)
HMS ''Ark Royal'' (R09) was an aircraft carrier of the Royal Navy and, when she was decommissioned in 1979, was the Royal Navy's last remaining CATOBAR, conventional catapult and arrested-landing aircraft carrier. She was the first aircraft carrier to be equipped with angled flight deck at its commissioning; her sister ship, , was the Royal Navy's first angle-decked aircraft carrier after modification in 1954. ''Ark Royal'' was the only non-United States vessel to operate the McDonnell Douglas Phantom in UK service, McDonnell Douglas Phantom at sea. Construction and modifications ''Ark Royal'' was the sister ship to , which was initially named HMS Audacious, HMS ''Audacious'', hence the name of the class. Four ''Audacious''-class ships were laid down, but two (HMS ''Africa'' and the original HMS ''Eagle'') were cancelled when the Second World War ended, and construction of the other two was suspended for several years. Both surviving ships were extensively upgraded throughou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bacchante From Targatness June73 Proc
In Greek mythology, maenads (; grc, μαινάδες ) were the female followers of Dionysus and the most significant members of the Thiasus, the god's retinue. Their name literally translates as "raving ones". Maenads were known as Bassarids, Bacchae , or Bacchantes in Roman mythology after the penchant of the equivalent Roman god, Bacchus, to wear a bassaris or fox skin. Often the maenads were portrayed as inspired by Dionysus into a state of ecstatic frenzy through a combination of dancing and intoxication. During these rites, the maenads would dress in fawn skins and carry a thyrsus, a long stick wrapped in ivy or vine leaves and tipped with a pine cone. They would weave ivy-wreaths around their heads or wear a bull helmet in honor of their god, and often handle or wear snakes. These women were mythologized as the "mad women" who were nurses of Dionysus in Nysa. Lycurgus "chased the Nurses of the frenzied Dionysus through the holy hills of Nysa, and the sacred implement ...

Mutual Defense Assistance Act
The Mutual Defense Assistance Act was a United States Act of Congress signed by President Harry S. Truman on 6 October 1949. For US Foreign policy, it was the first U.S. military foreign aid legislation of the Cold War era, and initially to Europe. The Act followed Truman's signing of the Economic Cooperation Act (the Marshall Plan), on April 3, 1948, which provided non-military, economic reconstruction and development aid to Europe. The 1949 Act was amended and reauthorized on July 26, 1950. In 1951, the Economic Cooperation Act and Mutual Defense Assistance Act were succeeded by the Mutual Security Act, and its newly created independent agency, the Mutual Security Administration, to supervise all foreign aid programs, including both military assistance programs and non-military, economic assistance programs that bolstered the defense capability of U.S. allies. About the same time, the Mutual Defense Assistance Control Act of 1951, also known or referred to as the Battle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
