Thales will supply the sonar system to BAE Systems Maritime - Submarines, the prime contractor for the Astute Class build, to be fitted to the submarines at its shipyard in Barrow-in-Furness. The complete sonar system supplied by Thales will comprise both inboard and outboard of the bow, fin, intercept and flank arrays, and the associated inboard processing. Thales has now been contracted to supply Sonar 2076 for all seven Astute Class boats.
