HMS Audacious is the fourth Astute-class nuclear-powered fleet submarine of the Royal Navy. Several previous vessels of the Royal Navy have borne the name. Long lead items for her construction were ordered on 28 August 2006 [3] although the actual order was not placed until 21 May 2007.[4] She was nearly halfway through her build programme as of December 2012.[5]
Design
Nuclear power
Audacious's nuclear reactor will not need to be refuelled during the boat's 25-year service. Since the submarine can purify water and air, she will be able to circumnavigate the planet without resurfacing. The main limit is that the submarine will only be able to carry three months' supply of food for 98 officers and ratings.
Weapons
Audacious will have provision for up-to 38 weapons in six 21-inch (533 mm) torpedo tubes:[6]
- Tomahawk Block IV land-attack missiles - range of 1,240 miles (2,000 kilometres)
- Spearfish heavyweight torpedoes
