Question to the Ministry of Defence:

To ask the Secretary of State for Defence, with reference to his Department's press release entitled UK unveils new undersea warfare technology to counter threat from Russia, published on 8 December 2025, if he will list the firms from (a) the UK and (b) Europe that have submitted proposals to develop anti-submarine sensor technology.

The Royal Navy will be deploying new undersea warfare technology as part of Atlantic Net, a new initiative that will see the Royal Navy rapidly field and iterate undersea warfare technology in collaboration with a commercial mission partner or partners. The competition for the first Atlantic Net commercial competition closed on 26 Nov 2025. I know the Hon. Gentleman will recall from his time as a Defence Minister that public disclosure on the companies that have submitted proposals, or a breakdown of firms and capabilities involved would prejudice fair competition.
