  Astute class submarine - Wikipedia, the free encyclopedia
The Astute class submarines are the next generation nuclear attack submarines of the Royal Navy.
Original plans were for seven boats of the Astute class to replace five Swiftsure-class submarines (Sovereign, Superb, Sceptre, Spartan, and Splendid) and the two oldest Trafalgar-class boats (Trafalgar and Turbulent).
It will be the first Royal Navy submarine class to have a bunk for each member of the ship's company, ending the practice of 'hot bunking', whereby two sailors on opposite watches shared the same bunk.

 Trafalgar class submarine - Wikipedia, the free encyclopedia
The Trafalgar class submarines are, until the introduction of the Astute class, the Royal Navy's most advanced nuclear fleet submarines (SSNs).
It is an attack submarine and is essentially a refinement of the Swiftsure class, designed six years later than its predecessor.
The Trafalgar class was to be replaced by the Future Attack Submarine (FASM), however this project was effectively cancelled in 2001 and replaced by the Maritime Underwater Future Capability.

 Submarine -   (Site not responding. Last check: 2007-11-06)
Large military submarines are generally classified either as attack submarines (designed to operate in the hunter-killer role against enemy shipping, including other submarines) or strategic ballistic-missile submarines, designed to launch attacks on land-based targets from a position of stealth.
Submarines designed for the purpose of attacking merchant ships or other warships are known as "fast attacks", "hunter-killers", "fast boats", or "fleet submarines" (which terms are not synonyms; each is a different design for a different mission).
The names of Royal Navy submarine classes, including ballistic missile submarines, are letter-based; thus, all boats of the Swiftsure class begin with the letter S and the Trafalgars, the letter T. Royal Navy submarines were originally designated alphanumerically, such as HMS A1 of the A-class of 1903 (built by the pioneer designer, John P. Holland).

 Astute attack submarine
During World War II the submarine service came into its own and since that time boats have become increasingly larger and faster and now the latest name in the long line of famous classes is Astute.
Meanwhile, the study into the Batch 2 Trafalgar class submarines continued and it became apparent that further development of the Trafalgar class was the way forward.
Astute is the biggest and most powerful attack submarine to be built for the Royal Navy and, under the Smart Acquisition Programme, is being built roughly one-fifth more quickly than earlier boats.

 Barrow Built Boats
The D Class, approved by the Admiralty Board in 1906, was designed to overcome, as far as possible, the limitations of the earlier submarine classes.
With this class it appears that the Admiralty finally decided that the submarine deserved the dignity of a name; thus, the pioneer of the class was called Oberon.
The Royal Navy's Astute class submarine is a nuclear powered attack submarine which is to replace the five Swiftsure class submarines launched between 1973 and 1977 and are approaching the end of their operational life.

Astute will already have a larger torpedo room than Virginia (36 weapons vs. 26) and more horizontal torpedo tubes (6 vs. 4), so the net warloads are about the same (36 vs 38).

 Astute Class Submarines (SSNs)
These resurrected names last used for the A Class conventional submarines that first entered service towards the end of the Second World War and it was the first time that a batch of submarines had been ordered together, as in the past nuclear submarines had been ordered singly, on an incremental basis.
The Astute Class submarines will also carry Tomahawk, but at the moment will be unable to fire the new Tactom (tactical tomahawk), currently under development by the Americans, as the current model can only be launched vertically while Astute will launch tomahawk from torpedo tubes.
The first steel for Astute was cut in November 1999 and her keel laying ceremony took place on January 31st 2001, one hundred years after the keel laying of Holland 1, the Royal Navy's first submarine.

The Astute-class submarine is a development of the current Trafalgar-class boats, but at 7,500 tons displacement when submerged they are around 33 per cent bigger than their predecessors.
– designers found that the old principle of building a submarine as small as possible no longer brought benefits, and there were drawbacks in terms of accessing parts of the boat’s systems.
Because the new philosophy of ‘bigger is better’ has been followed, they will be built 20 per cent faster than the T-boats and their through-life costs will be ten per cent cheaper – partly because their nuclear reactors will not have to be refuelled throughout the boats’ 25-year lifespan.

 UK Shipbuilding: a new direction
In 1995 at the launch of HMS Vanguard, the first Trident submarine, at Barrow, the chairman of VSEL made the passing observation that because of declining demand for Royal Navy warships there was not, nor would there be, enough work to go around the existing number of warship yards.
In fact, he stunned his audience with the estimate that there was sufficient work to keep only one yard fully occupied, the VSEL Barrow yard being the only one with the facilities and skills to cover the whole range of navy vessels.
This can be for periods as long as eight years as in the case of the new Astute-class submarine or for the whole life (25 years) in the case of the navy's new hydrographic and oceanographic vessels.
