Thales UK To Build Dreadnought-Class Submarine Periscopes

The company has been building periscopes for the Royal Navy for more than 100 years.

Defence firm Thales UK has been awarded a £330 million contract to work on the Royal Navy's Dreadnought-class submarines.

Part of the deal, awarded by lead manufacturer BAE Systems Submarines, will see the company build periscopes for all four of the next generation of nuclear submarines.

The announcement was made by defence minister Baroness Goldie in Glasgow.

"This sub-contract win by Thales clearly demonstrates the importance of the £31 billion Dreadnought programme to UK and Scottish industry," Baroness Goldie said.

The periscopes, also known as 'Combat System Masts', are worth £41.3 million.

The remaining £291.5 million of the contract is going towards work on "underwater systems", according to the Ministry of Defence (MOD).

Technology on the masts include a visual and situational awareness sensor, as well as a sonar system.

While electronic warfare technology and cameras will provide a "visual link" to submariners, the MOD said.

The periscopes will be built at Govan in Glasgow and 520 jobs are being created across the UK as part of the project. 

Dreadnought-class submarines are due to enter service in the early 2030s.

The £31 billion programme will see the vessels take over from the Vanguard-class submarines as the UK's nuclear deterrent. 

Thales UK has been building periscopes for the Royal Navy for more than 100 years, and working with the MOD since the start of the UK's Continuous At Sea Deterrent in 1969.
