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 capabilities that are due to be deployed in the water in 2026.

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.
