UK Defence Secretary Michael Fallon has announced an investment of £1.3bn with defence fim BAE Systems for the Royal Navy’s Successor nuclear submarine programme.
This investment is a part of the country's £178bn equipment plan.
BAE Systems will build four new Successor ballistic missile submarines.
The Successor submarines will replace the navy's existing fleet of four Trident missile Vanguard-class nuclear submarines from the 2030s.
The new submarines will have a lifespan of three decades.
Fallon said: “Britain’s ballistic missile submarines are the ultimate guarantee of our nation’s safety we use them every day to deter the most extreme threats.
“We cannot know what new dangers we might face in the 2030s, 2040s and 2050s so we are acting now to replace them.
“Along with increasing the defence budget to buy new ships, planes and armoured vehicles, this shows that this Government will never gamble with our national security.”
With Fallon's announcement, the Successor project has moved into Delivery Phase 1.
This phase will see the commencement of structural steel manufacture for the ‘auxiliary machine space’ of the first submarine.
The £1.3bn will be invested on advancing the design of the submarine, purchasing materials and long lead items, as well as on facilities at the BAE Systems yard in Barrow-in-Furness where the submarines will be built.
