The UK's Ministry of Defence has applied to build a large space radar station at Cawdor Barracks in Brawdy, Pembrokeshire, and the decision on whether to approve it will now be made by Welsh government ministers rather than the local council. The Welsh government's power to "call in" planning applications is used rarely, reserved for cases raising issues of more than local importance, and campaigners opposed to the project have welcomed the move as a chance for wider scrutiny.

The scheme would see 27 radar dishes, each 66ft (20m) high and 49ft (15m) wide, built as part of the trilateral AUKUS security partnership between the UK, US and Australia, forming the Deep Space Advanced Radar Capability (DARC), which the UK government says is needed to track objects in deep space and protect satellite, communication and navigation networks. Only a handful of the roughly 25,000 planning applications made in Wales each year are called in this way. The campaign group People Against Radar Campaign (PARC) argues the facility is intended for the US Space Force and represents a "significant escalation in the militarisation of space", while the Plaid Cymru-led Welsh government has declined to comment on its decision to call in the application.
