UK’s new space radar can detect football-sized threats 22,000 miles away

Plans to establish a network of advanced radars to monitor deep space activity are moving forward in Pembrokeshire, despite strong opposition from local campaigners.

The Deep Space Advanced Radar Capability (Darc) will see the construction of 27 radar dishes, each standing 20 meters tall, on the St Davids peninsula. These high-tech radars are designed to track objects as small as a football and are part of a broader global network aimed at enhancing space defense.

The radar system, to be developed at Cawdor Barracks in southwest Wales, is a key initiative under the Aukus defense partnership involving the UK, US, and Australia. The network will span three countries and is intended to monitor and track objects up to 22,000 miles (36,000 kilometers) away from Earth.

The UK Ministry of Defence (MoD) sees this project as essential for safeguarding against potential space-based threats.

Strategic importance and local impact

John Healey, the UK Defence Secretary, emphasizes the significance of the Darc project, noting that it will not only secure jobs but also play a crucial role in future defense strategies.

“Space plays a crucial role in our daily lives – used by everything from our mobile phones to banking services,” Healey stated . “It is also used by UK defence to conduct vital tasks such as supporting military operations, navigating forces and gathering intelligence. This new radar programme will not only enhance our awareness of deep space, but also help protect our space assets alongside our closest partners.”

The radar system will match the reach of geostationary orbit, providing detailed intelligence on satellites. With the number of satellites projected to surge from approximately 9,000 this year to 60,000 by 2030 , the Darc network aims to address increasing concerns over space security.

Dr. Mark Hilborne, leader of the space security research group at King’s College London, underscores the importance of this initiative , “There is a concern about increasing military activity and increasing belligerence in space. We need more eyes on the sky.”

Controversy and community resistance

Local opposition to the project has been vocal. Campaigners have launched a movement called Parc Against Darc, denouncing the plans as “one of the most health-hazardous, tourism-ruining, skyline-blighting military installations ever proposed anywhere in the UK.”

This opposition echoes a historical campaign from 1990, when a similar radar installation was halted after public outcry led to its cancellation by then-Prime Minister Margaret Thatcher.

The MoD has committed to engaging with the local community throughout the development process. Two public information events are scheduled for September, where the Darc programme team will present the plans, answer questions, and gather local feedback.

Additionally, an environmental impact assessment is being conducted to address concerns and support the planning application to Pembrokeshire County Council.

As the radar system is expected to become operational by 2030, the redevelopment of Cawdor Barracks, which will also secure at least 100 jobs, will proceed once safety and environmental reviews are completed.
