How good is the Astute class submarine?
Did you know… Astute class submarines are the UK’s largest and most powerful attack submarines and can strike at targets up to 1,000km from the coast with pin-point accuracy. Astute submarines are the first nuclear submarines to be designed entirely in a three-dimensional, computer-aided environment.
What is the most deadliest submarine in the world?
Four of these eleven boats (U-35, U-39, U-38, and U-34) were the four top killers of World War I; indeed, they were four of the five top submarines of all time in terms of tonnage sunk (the Type VII boat U-48 sneaks in at number 3). U-35, the top killer, sank 224 ships amounting to over half a million tons.
Does the Astute class submarine carry nuclear weapons?
The PWR3 has a longer life over the 25-year life PWR2 reactor fitted to the other Astute boats. Since it is nuclear powered, the boat has theoretically unlimited endurance, though in practice it is limited to 90 days at sea based on food carried (including 18,000 sausages and 4,200 Weetabix) and crew endurance.
How does the Royal Navy Astute class submarine work?
It is guided either by a copper wire or closes on to its target using its inbuilt sonar, delivering a 660lb explosive charge. That detonates either when it strikes the hull of an enemy submarine, or via an acoustic proximity fuse underneath the target.

In December 2012, BAE Systems received a £1.2bn ($1.9bn) contract from the UK MoD for the design, construction, test and commissioning programme of Audacious.
