Question to the Ministry of Defence:

To ask the Secretary of State for Defence, with reference to his Department’s press release entitled New radar systems to unlock offshore wind, published on 20th March 2026, what assessment he has made of the impact of offshore wind turbines on the performance of existing radar systems prior to this upgrade.

The new radar systems have met the Ministry of Defence's (MOD) requirements and represent the optimal solution currently available. This option is supported by a robust and well-documented methodology that provides the MOD the confidence that the solution can effectively mitigate the adverse impact of offshore wind turbines on long-range Air Defence radars. The MOD will continue to rigorously assess and implement appropriate mitigation measures to ensure that any offshore wind farm, with the potential to affect Air Defence radar operations, is only approved once these safeguards are firmly in place.

The MOD continues to support the Government’s Clean Power Mission.
