Astute class is the largest, most advanced and most formidable vessel of its kind ever operated by the Royal Navy. She incorporates the latest stealth technology combined with a world beating sonar system and equipped with Spearfish torpedoes and state of the art Tomahawk land attack missiles to make her a supremely effective naval asset.

The Astute class will progressively replace the Swiftsure and Trafalgar classes.

Displacing 7,400 tonnes and measuring 97 metres, HMS Astute is significantly larger than the Swiftsure and Trafalgar class submarines but requires fewer crew to operate her due to the advanced technology and automated systems on board.

When she becomes operational on completion of Sea Trials she will be capable of circumnavigate the globe without surfacing and with the advance of nuclear technology she will never need refuelling.

HMS Astute is designed to fulfill a range of key strategic and tactical roles including anti-ship and anti-submarine operations, surveillance and intelligence gathering and support for land forces.
