The Royal Navy has a new hunter-killer submarine in its arsenal of weapons. Its name: HMS Ambush.

The submarine has the ability to send guided missiles at the enemy more than 1,000 miles away, and it will never need refueling and can detect ships approaching at 3,000 nautical miles away.

This titan of the sea is able to make oxygen and fresh water from ¬seawater, to keep the 98 crew members alive in time of crisis, the U.K. DailyMail reports.

Ambush replaces smaller vessels such as the ¬Swiftsure and ¬Trafalgar subs, but despite its size  is much quieter, making it virtually undetectable to enemy vessels.

The U.K. Daily Mail reports that the vessel is more complex than U.S. space shuttles and is able to ¬circumnavigate the globe ¬without surfacing.

Ambush is 291 feet long, as wide as four double-decker buses and 12 stories high. HMS Ambush will carry 38 ¬missiles as ammunition. Its nuclear-powered engine will propel the submarine through the water at more than 20 knots, allowing it to travel 500 miles a day, U.K. DailyMail reports.

This super sub cost $1.2 billion dollars and will be launched at Barrow-in-Furness in Cumbria, U.K. on Thursday.
