Thales secured the contract from BAE Submarines which is building the vessels for the Royal Navy in a deal by the UK Ministry of Defence.

Alex Cresswell, CEO of Thales UK,  said: “We are proud to say that our combat system mast and sonar will be providing the eyes and ears capabilities of the new Dreadnought Class.

“The boat build, led by BAE Systems and partners, will be another milestone showcase of UK engineering skills and innovation.

“It is an incredibly exciting time for the Submarine Service and its contribution to global security with the build of the Dreadnought class and as we look to the development of the AUKUS submarine programme that will deliver a future capability for Australia and the UK.”

James Cartlidge, UK Minister for Defence Procurement, said: “This is a clear investment in maintaining the United Kingdom’s nuclear deterrent.

“By providing the ‘eyes’ of the new Dreadnought Class Submarine, this technology will play a key role in keeping the country safe. The Dreadnought programme will support tens of thousands of UK jobs, boosting the economy and defending our nation.”
