Design

The Vanguards were designed from the outset as an unlimited-range[citation needed] nuclear powered ballistic missile submarine, unlike the previous Resolution-class which was adapted from the then existing Valiant class and the American Lafayette class of nuclear powered fleet submarines (SSN in US terms). At more than 150 metres long and 16,000 tons submerged displacement the Vanguards are roughly twice the size of the Resolutions, and are the third largest submarines ever built, by displacement when surfaced, after the Russian Typhoon and American Ohio classes. The great increase in size is largely related to much larger size of the Trident D-5 missile as compared to Polaris. The Resolution class submarines were the first British strategic ballistic missile submarines, carrying the Polaris missile. ... The Valiant-class were the first fully British nuclear fleet submarine, as the first nuclear submarine, HMS Dreadnought, actually used an American nuclear reactor. ... The Lafayette class of submarine was an evolutionary development from the Ethan Allen class of fleet ballistic missile submarine, slightly larger and generally improved. ... SSN is the United States Navy Hull classification symbol for a general-purpose fast attack submarine. ... The Typhoon class submarine is a type of nuclear-powered ballistic missile submarine deployed by the Soviet Navy in the 1980s. ... The United States has 18 Ohio class submarines: 14 nuclear-powered SSBNs, each armed with 24 Trident II SLBMs; they are also known as Trident submarines, and provide the sea-based leg of the nuclear triad of the United States strategic deterrent forces 4 nuclear-powered SSGNs, each armed with... The Trident missile, named after the trident, is an intercontinental ballistic missile (ICBM) which is armed with nuclear warheads and is launched from submarines (SSBNs), making it a SLBM. The Trident was built in two variants: the I (C4) UGM-96A and II (D5) UGM-133A. The C4 and D5... The Polaris Missile was a submarine-launched ballistic missile (SLBM) carrying a nuclear warhead developed during the Cold War for the United States Navy. ...


The Vanguards were designed and built at Barrow-in-Furness by Vickers Shipbuilding and Engineering Limited (VSEL), now BAE Systems Submarines. The Devonshire dock hall was built specifically to build these submarines. The missile compartment is based on the system used on the Ohio class, though only 16 missiles are carried rather than the 24 of the Ohio. Barrow-in-Furness is a town in Cumbria, England. ... Vickers Shipbuilding and Engineering, Ltd (VSEL) was a shipbuilding company based at Barrow-in-Furness, Cumbria in northwest England that builds warships and armaments. ... BAE Systems Submarines, until 2003 a unit within BAE Systems Marine, is responsible for the development and production of the Astute class submarine. ...


In addition to the missile tubes the Vanguard class is fitted with four 21 inch (53.3 cm) torpedo tubes and carries the Spearfish heavyweight torpedo[1], allowing it to engage submerged or surface targets at ranges up to 65 kilometres (40 miles). Two SSE Mark 10 launchers are also fitted to allow the boats to deploy Type 2066 and Type 2071 decoys, and a UAP Mark 3 electronic support measures (ESM) intercept system is fitted. A modern torpedo, historically called a locomotive torpedo, is a self-propelled projectile that (after being launched above or below the water surface) operates underwater and is designed to detonate on contact or in proximity to a target. ... The Spearfish torpedo is the heavy Acoustic homing torpedo used by the submarines of the Royal Navy. ...


HMS Vanguard, Victorious, Vigilant and Vengeance were commissioned in 1993, 1995, 1996 and 1999 respectively.


Sensors

Vanguard carries the Thales Underwater Systems Type 2054 composite sonar. The Type 2054 is a multi-mode, multi-frequency system, which incorporates the 2046, 2043 and 2082 sonars. The fleet is in the process of having their sonars refitted to include open architecture processing using commercial off the shelf technology. Thales Underwater Systems (TUS), formerly known as Thomson Marconi Sonar, is a defence manufacturer specialising in Sonar for Submarines and Surface Ships, as well as Airborne sonar systems, and communications masts and systems for Submarines. ... The F70 type frigates (here, La Motte-Picquet) are fitted with VDS (Variable Depth Sonar) type DUBV43 or DUBV43C towed sonars SONAR (SOund Navigation And Ranging) â€” or sonar â€” is a technique that uses sound propagation under water (primarily) to navigate, communicate or to detect other vessels. ...


A Type 2043 hull-mounted active/passive search sonar is also carried, as is a Type 2082 passive intercept and ranging sonar. Finally a Type 2046 towed array is carried. This operates at very low frequency, giving a passive search capability.


Two periscopes are carried, a CK51 search model and a CH91 attack model. Both have a TV camera and thermal imager as well as conventional optics. Principle of the periscope. ...


A Type 1007 I-band navigation radar is also carried. This long range radar antenna, known as ALTAIR, is used to detect and track space objects in conjunction with ABM testing at the Ronald Reagan Test Site on the Kwajalein atoll. ...


Command System

A specialised Submarine Command System (SMCS) was originally developed for the Vanguard boats and was later used on other Royal Navy submarines.[2] SMCS, the Submarine Command System, was first created for the Royal Navys Vanguard class submarines. ...


Propulsion

A new pressurised water reactor, the PWR 2, was designed for the Vanguard class. This has double the service life of previous models, and it is estimated that a Vanguard class submarine could circumnavigate the world 40 times without refuelling. This should allow the class to carry out their entire service life without the need for expensive refuelling. The reactor drives two GEC turbines linked to a single shaft pump jet propulsor. This propulsion system gives the Vanguards a maximum submerged speed of 25 knots. There are two Paxman diesel alternators and two turbo generators from WH Allen for backup. A pressurized water reactor (PWR) is a type of nuclear power reactor that uses ordinary (light) water for both coolant and for neutron moderator. ... Typical jet ski pump jet A pump-jet or water jet is a marine system that creates a jet of water for propulsion. ...

Vanguard class submarine - Wikipedia, the free encyclopedia (681 words)
The principle of operation is based on maintaining deterrent effect by always having at least one submarine at sea, and was designed for the Cold War period.
One submarine is normally undergoing maintenance and the remaining two in port or on training exercises.
However, the British government announced in 1998 that each submarine would carry only 48 warheads (halving the limit specified by the previous government), which is an average of three per missile.
