Thales awarded sensor contracts for Dreadnought submarine programme

28 February 2020

Thales UK has been awarded contracts worth around GBP330 million to develop the sonar suite and above-water sensor systems for the new Royal Navy (RN) Dreadnought-class nuclear-powered ballistic missile submarines (SSBNs).

Previously known as Successor, the GBP 31 billion Dreadnought submarine programme is planned to replace the RN's four existing Vanguard-class SSBNs - one for one, from the early 2030s - to maintain a posture of continuous at-sea deterrence.

Manufacture work on the first two 17,200-tonne displacement boats is under way at the BAE Systems Maritime - Submarines' Barrow-in-Furness shipyard facility in Cumbria.

Under a contract to BAE Systems valued at GBP291.5 billion, Thales will supply an evolved variant of the in-service Sonar 2076 sonar suite to equip the new Dreadnought-class boats.
