Prior to 1982, Invincible's air group consisted purely of Sea King HAS1 anti-submarine aircraft and Sea Harrier FRS1 aircraft. Typically, nine Sea Kings, and four or five Sea Harriers were embarked. This was due to the fact that the originally envisioned mission for the ships was to provide the heart of ASW hunter-killer groups in the North Atlantic during a war against the Soviet Union. In that context, the main weapon of the carrier would not be its fighter aircraft, but its ASW helicopters. The fighters were on board to shoot down the occasional Soviet m ...

When they entered service the ships were primarily intended for long-range anti-submarine warfare. Their primary weapon for this role was their complement of two CH-124 Sea King helicopters, which could be launched in even high sea states due to their "bear trap" winch system. The ship included a hangar that provided an enclosed working space for both helicopters at the same time. The helicopters were backed up by two triple-mount torpedo launchers firing Mk.44 and M ...

Originally conceived under the multi-national 'Horizon' project, from which the UK withdrew, the Daring Class destroyers represent the largest escorts ever built for the RN, second only to the Tiger class guided missile cruisers of the post-Second World War era. Six ships have been ordered and a total of eight are expected to enter service by 2014. The original planned purchase of twelve was reduced in the Ministry of Defence's Delivering Security in a Changing World: Future Capabilities review, published in July ...

The Prometheus, otherwise known as the BC-303 (formerly X-303), is Earth's first capital starship. Although small compared to a Goa'uld Ha'tak mothership, it is a large battlecruiser nonetheless, ten times the size of an Al'kesh. It dwarfs its two predecessors, the X-301 Interceptor and the X-302, which accommodated only two people each. Despite some difference of opinion (Colonel O'Neill wanted to name the ship Enterprise, on the grounds that Prometheus was "a Greek tragedy"), it was finally named PrometheusSee also:

The Type 42 Destroyer was built to fill the gap left by the cancellation of the large Type 82 destroyer. It was intended to fulfil the same role, with similar systems yet on a smaller and more cost effective hull. The ships are primarily carriers for the GWS-30 Sea Dart surface-to-air missile system. Although claimed to be obsolete, it is still effective against most modern missile threats, as proven in the 1991 Gulf War. The Type 42 is also equipped with a 4.5 inch (114 mm) gun, six torpedo launchers, and two Vulcan Phalanx Mk.15 Clo ...

Most western militaries integrate air defence purely with the traditional arms of the military (i.e. army, navy and air force). This is in contrast to some (largely communist or ex-communist) countries where not only are there provisions for air defence in the army, navy and air force but there are specific branches which deal only with the air defence of territory. For example, the Soviet PVO Strany. It should be noted that the USSR also had a separate strategic rocket force in charge of, among other things, nuclear ICBMs.< ...

In more recent years, three other changes have occurred. One of those was the removal of the Sea Dart system, creating an increased deck park for aircraft, making the ships a great deal more like pure aircraft carriers, than the cross between cruisers and aircraft carriers that they were originally built as. It is quite surprising how much the removal of the SAM system and its associated fire control radars alters the lines of the ships when viewed from the front. In company with that, the ships magazines were fitted to routinely handle RAF ...

The active long-hull Perrys are being modified to reduce operating costs. The Detroit Diesel generators are being replaced with modern Caterpillar units and the Mk13 single arm missile launcher is being removed because the missile it is meant to fire, the Standard SM-1MR has outlived its service life. It would be costly to refit the SM-1MRs, which have marginal ability to bring down sea-skimming missiles. (One of the other reasons for the withdrawal is to conserve what little support remains for the SM-1MR, which is still used by countries s ...

Anti-aircraft warfare - Mobility. Most modern air defence systems are fairly mobile. Even the larger systems tend to be mounted on trailers and are designed to be fairly quickly broken down or set up. In the past, this was not always the case. Early missile systems were cumbersome and required much infrastructure - many could not be moved at all. With the diversification of air defence there has been much more emphasis on mobility. Most modern systems are usually either self-propelled (i.e. guns or missiles are m ...

The Type 45 destroyers will be 152.4 m in length, with a beam of 21.2 m and a draught of 5.0 m. This makes them significantly larger than the Type 42 destroyers they replace, displacing 7,350 tonnes compared to 5,200 tonnes of the Type 42. The Type 23 frigates were the first British warships to incorporate signature reduction technology, with the large 7° angle of the bow, the elimination of right angles and reduced equipment on deck. The propulsion system was also chosen to minimise noise, with electric generators providing minimal acoustic signature for anti-submarine warfare (ASW) missions. Infrared signature i ...

Sea Dart missile - Falklands War. Sea Dart was used during the Falklands War and is credited with 8 confirmed kills, including a high-flying Canberra reconnaissance aircraft outside the official engagement envelope and low-flying attack aircraft. However, it was found to be unsuitable when operating close inshore as it was unable to get a lock on a targets at distance obscured by land and fast-moving low-level targets obscured in ground clutter or sea-returns. These shortcomings were more damning of the Ty ...

In the next few years, the Sea Harrier is to be retired, with the three squadrons that use the type being disbanded between early 2004 and 2006. After that, the RAF Harrier GR.9 will make up all of the fixed wing aircraft that operate on board the class, although some will continue to be flown by navy pilots. HMS Invincible was decommissioned in July 2005, and has been mothballed (available for reactivation on notice) until 2010. HMS Illustrious has taken over as the Flagship and is planned to decommission in 2012, and HMS A ...

Natural uranium metal contains about 0.71% U-235, 99.28% U-238, and about 0.0054% U-234. Depleted uranium contains only 0.2% to 0.4% U-235, the remainder having been removed and concentrated into enriched uranium through the process of isotope separation. The enrichment process does not create U-235 but merely separates the different isotopes of uranium. Therefore the process leaves large amounts of U-238 uranium as a byproduct. This byproduct is refered to as depleted uranium. For example producing 1 kg of 5% enriched uranium requires 11.8 kg of natural ura ...

Civilian applications for depleted uranium are fairly limited and are typically unrelated to its radioactive properties. It primarily finds application as ballast because of its high density. Such applications include sailboat keels, as counterweights and sinker bars in oil drills, gyroscope rotors, and in other places where there is a need to place a weight that occupies as little space as possible. Other relatively minor consumer product uses have included: the manufacture of pigments and glazes; incorporation into dental porcelain used for false teeth to simulate the fluorescence of natural teeth; and i ...

Prometheus was hijacked before completion by rogue NID agents demanding the release of Colonel Frank Simmons and the Goa'uld infested Adrian Conrad. SG-1 managed to reclaim control of the ship, and were enlisted by the Asgard to help them trap the Replicators within a time dilation bubble. The Asgard thanked Earth by fitting advanced systems onboard the X-303. The ship was subsequently finished and began a shakedown cruise. A problem with the hyperdrive engines forced the crew to eject the reactor in ...

The ships are all scheduled to be out of service by 2014. Initially, the UK sought to procure replacements first in collaboration with seven other NATO nations under the NFR-90 project and then with France and Italy through the Horizon CNGF programme. However, both these collaborative ventures failed and the UK decided to go it alone with a national project. The Type 42s are now to be replaced by eight Type 45 destroyers. The first six Type 45s; HMS Daring, Dauntless, Defender, Dragon, Duncan and ...
