Submarines are now the seat of every under cover operations carried out by many great nations.British newest submarine was launched – quietly – end of April, beginning of May, and it is built for stealth. HMS Audacious is in theory able to stay underwater for 25 years without the need to come to the surface.HMS Audacious, which was launched at BAE Systems’ yard in Barrow-in-Furness, Cumbria, is one of seven subs of the Astute class, which are designed to be the quietest subs in the world.
It is set to go into service in 2018 and is equipped with nuclear reactors which are big enough to power a city the size of Swindon. They are designed in such a way that they do not need refueling until 2043. They are also able to travel hundreds of miles and their maximum diving depth is a classified secret.
The seven Astute submarines will take over from the Swift sure class, which have all now been retired, and the Trafalgar class, which were launched between 1983 and 1991 and will be decommissioned within the next ten years.
They are designed to remain hidden in the ocean somewhere around the globe for months on end, even years. Fresh water is made by distilling sea water and oxygen is produced by separating water (H2O). Carbon dioxide is removed using special gadgets.
But of course HMS Audacious and her sister ships — the Astute, Ambush, Artful, Anson, Agamemnon and Ajax — will have to return to port occasionally and submariners will not turn gray underwater.
Their food supplies will usually last around three months and being submerged — and away from natural light and fresh air — places a massive burden on the crew’s mental and physical health.
“They are very good at intelligence gathering, sea denial and sinking other subs. They are even specially fit so that they can land special forces without surfacing,” Lord West added.
But he said, ideally, the Navy needed eight, not seven Astute class subs.This has is a essential for undercover operations.The Royal Navy currently has four submarines which carry the UK’s nuclear deterrent, the US-manufactured Trident missiles. The government has said it plans to replace the Vanguard-class boats with the Successor class, which will carry a new missile, again made in the US.
The Labour Party has been heavily divided over the issue of renewing Trident. The party’s leader, Jeremy Corbyn, and a large section of the membership believe Britain should dispense with a weapon it would never in reality ever use, especially considering the billions involved.
