HMS Rhyl (F129)
HMS ''Rhyl'' was a ''Rothesay''-class or Type 12M anti-submarine frigate of the Royal Navy, launched by Lady Macmillan on 23 February 1959 and commissioned in October 1960. Following Royal Navy service she was scuttled whilst being prepared as a target in 1985. Design The ''Rothesay'' class was an improved version of the anti-submarine frigate, with nine ''Rothesay''s ordered in the 1954–1955 shipbuilding programme for the Royal Navy to supplement the six ''Whitby''s. ''Rhyl'' was long overall and between perpendiculars, with a beam of and a draught of . The ''Rothesay''s were powered by the same Y-100 machinery used by the ''Whitby'' class. Two Babcock & Wilcox water-tube boilers fed steam at and to two sets of geared steam turbines which drove two propeller shafts, fitted with large ( diameter) slow-turning propellers. The machinery was rated at , giving a speed of . Crew was about 212 officers and ratings. A twin 4.5-inch (113 mm) Mark 6 gun mount was fit ...

Naval Rating

Specifically, ''rate'' is the term used to describe generically all members of all ranks below a warrant officer; whereas ''rating'' is part of the official name of individual specific ranks, such as Able Rating and Leading Rating. The term comes from the general nautical usage of 'rating', to refer to a seaman's class or grade as recorded in the ship's books. The system of conferring authority on sailors i ...

Keel Laying
Laying the keel or laying down is the formal recognition of the start of a shipbuilding, ship's construction. It is often marked with a ceremony attended by dignitaries from the shipbuilding company and the ultimate owners of the ship. Keel laying is one of the four specially celebrated events in a ship's life; the others are Ceremonial ship launching, launching, Ship commissioning, commissioning, and Ship decommissioning, decommissioning. Earlier, the event recognized as the keel laying was the initial placement of the central timber making up the backbone of a vessel, called the keel. As steel ships replaced wooden ones, the central timber gave way to a central steel beam. Modern ships are most commonly built in a series of pre-fabricated, complete hull sections rather than around a single keel. The event recognized as the keel laying is the first joining of modular components, or the lowering of the first module into place in the building dock. It is now often called "keel ...

Type 277 Radar
The Type 277 was a surface search radar, surface search and secondary aircraft early warning radar used by the Royal Navy and allies during World War II and the post-war era. It was a major update of the earlier Type 271 radar, offering much more power, better signal processing, new displays, and new antennas with greatly improved performance and much simpler mounting requirements. It allowed a radar with performance formerly found only on cruisers and battleships to be fitted even to the smallest corvettes. It began to replace the 271 in 1943 and was widespread by the end of the year. The Type 271 was one of the first microwave frequency radars to enter service, when microwave electronics design was in its infancy. While it was still being fitted to escort ships during 1941 and 1942, great strides in technique were being made in cavity magnetron, waveguide, antenna (radio), antenna design and general electronics. Those upgrades that could be easily combined with the existing syste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Foremast
The mast of a sailing vessel is a tall spar, or arrangement of spars, erected more or less vertically on the median line of a ship or boat. Its purposes include carrying sails, spars, and derricks, giving necessary height to a navigation light, look-out position, signal yard, control position, radio aerial, or signal lamp. Large ships have several masts, with the size and configuration depending on the style of ship. Nearly all sailing masts are guyed. Until the mid-19th century, all vessels' masts were made of wood formed from a single or several pieces of timber which typically consisted of the trunk of a conifer tree. From the 16th century, vessels were often built of a size requiring masts taller and thicker than from single tree trunks. On these larger vessels, to achieve the required height, the masts were built from up to four sections (also called masts). From lowest to highest, these were called: lower, top, topgallant, and royal masts. Giving the lower sections ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type 293 Radar
The Type 293 radar was designed as a short-range aerial-search radar This is a list of different types of radar. Detection and search radars Search radars scan great volumes of space with pulses of short radio waves. They typically scan the volume two to four times a minute. The radio waves are usually less than a ... for surface ships in 1945. It used the same transmitter as the Type 277 surface-search radar, but used a new antenna design intended to cover the area above the ship to provide air warning instead of surface search. The stabilised "cheese" antenna, diameter in the AUR antenna, was upgraded to in Type 293P and to in the postwar Type 293Q.Friedman, p. 197 Specifications Notes Bibliography * *{{cite book, last=Watson, first=Raymond C.

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. Operation Limbo was loaded and fired automatically with the crew under cover and was stabilised in pitch and roll. The firing distance of the mortars was controlled by opening gas vents; rounds could be fired from . The weapon was linked to the sonar system of the ship, firing on command when the target was in range. The rounds were projected so tha ...

Bofors 40 Mm Automatic Gun L/60
The Bofors 40 mm Automatic Gun L/60 (often referred to simply as the "Bofors 40 mm gun", the "Bofors gun" and the like, see #Name, name) is an Anti-aircraft warfare, anti-aircraft autocannon, designed in the 1930s by the Swedish arms manufacturer AB Bofors. The gun was designed as an intermediate anti-aircraft gun, filling the gap between fast firing close-range small calibre anti-aircraft guns and slower firing long-range high calibre anti-aircraft guns. For its time, the Bofors 40 mm L/60 was perfectly suited for this role and outperformed competing designs in the years leading up to World War II in both effectiveness and reliability. It entered the export market around 1932 and was in service with 18 countries by 1939. Throughout World War II it became one of the most popular and widespread medium-weight anti-aircraft guns. It was used by the majority of the western Allies of World War II, Allies and some Axis powers such as Nazi Germany and Hungary. In the po ...
