PLANS to establish a high-tech space radar facility in Pembrokeshire have sparked widespread debate, with proponents highlighting its strategic importance while opponents raise concerns over environmental, health, geopolitical risks, and the shifting global power dynamics.

The Ministry of Defence (MoD) intends to construct 27 radar dishes at Cawdor Barracks in Brawdy as part of the Deep Space Advanced Radar Capability (DARC) initiative. The facility, which will be one of three such sites globally, aims to track objects in geosynchronous orbit up to 22,000 miles from Earth. The project is being developed in partnership with the United States and Australia under the trilateral AUKUS security alliance.

Why the radar is needed

According to the MoD, the DARC system is essential for national security and global stability. Defence officials argue that space has become a contested domain, with nations such as Russia and China developing anti-satellite weapons that could threaten the UK’s communication and navigation infrastructure.

“The ability to track and identify potential threats in deep space is vital to maintaining the safety of our satellites, which underpin everything from mobile communications to military operations,” an MoD spokesperson said. “The DARC facility in Wales will significantly enhance our capacity to monitor space activity and deter hostile actions.”

Former Defence Secretary Grant Shapps described the radar system as a crucial element in countering emerging threats. “With the rise of space warfare capabilities among adversaries, the UK must invest in its ability to defend itself in this new frontier,” he said.

The MoD has also highlighted economic benefits, stating that the project will generate around 100 jobs and provide long-term investment in Pembrokeshire. Secretary of State for Wales Jo Stevens said the development would “secure jobs in the area and position the UK at the forefront of space surveillance technology.”

Geopolitical concerns and shifting alliances

Beyond local and environmental issues, campaigners have pointed to broader geopolitical uncertainties as a reason to oppose the radar project. The ongoing conflict in Ukraine, the fluctuating stance of the United States under President Donald Trump, and growing tensions with Russia and China contribute to unease about the UK’s role in global military strategies.

Jim Scott, a spokesperson for PARC, said: “Would you trust Donald Trump, who in recent weeks has switched sides in a global proxy war, to militarily dominate all of space using Pembrokeshire as a foothold? If not, we strongly urge people to take action against DARC.”

Campaigners suggest that recent US foreign policy shifts, including unpredictable decisions regarding support for Ukraine, cast doubt on the reliability of the United States as an ally. “The geopolitical landscape is more volatile than ever. If the UK becomes too dependent on American military projects, where does that leave us if alliances change?” asked Sarah Jenkins, a local resident.

Cefin Campbell, Plaid Cymru’s Member of the Senedd (MS) for Mid and West Wales, added: “This radar station represents an unnecessary provocation, locking Wales into a geopolitical contest that has little to do with our own security. It risks dragging Pembrokeshire into international disputes over which we have no control.”

Experts also warn that while the UK remains an important ally to the US, there is no guarantee that future administrations will maintain the same commitments. With NATO facing challenges due to political instability in member countries, some argue that the UK should reconsider placing strategic defence assets under US control. A military analyst speaking anonymously said: “There are valid concerns about whether we are investing in a long-term partnership with a country whose global positioning is uncertain.”

Environmental and tourism concerns

One of the main objections to the radar facility is its location. The proposed site is close to the Pembrokeshire Coast National Park, an area of outstanding natural beauty that attracts hundreds of thousands of visitors each year. Opponents worry that the construction of 20-metre-high radar dishes will have a lasting visual impact and could deter tourists from visiting the region.

“This will be a massive industrial complex in a protected area,” said Mark Williams, a local business owner. “Tourism is one of our biggest economic drivers, and we risk losing visitors if Pembrokeshire is associated with military infrastructure.”

There are also concerns about the potential health effects of high-frequency radar emissions. While the MoD insists that the facility will meet all health and safety regulations, campaigners argue that insufficient research has been conducted into the long-term impact of such radiation exposure.

Environmental groups have also expressed fears that the facility could disrupt local wildlife, particularly bird migration patterns. “We know very little about the long-term impact of this kind of technology on wildlife,” said Helen Davies of the Pembrokeshire Environmental Network. “Given the proximity to a national park, we should be taking a far more precautionary approach.”

History of opposition to military radar in Pembrokeshire

This is not the first time Pembrokeshire has resisted military radar developments. In the early 1990s, plans for a similar installation at St Davids Airfield were abandoned following widespread public outcry. Campaigners see the current DARC proposal as a revival of a decades-old issue and have vowed to fight against its approval.

“The community came together before to stop this, and we can do it again,” said Jenny Rees, a long-time resident and activist. “We do not want Pembrokeshire to be used as a pawn in global military strategies.”

The legacy of past opposition has led many locals to question whether the UK government is listening to public concerns. “We fought this once before, and we won,” said Gareth Morgan, who was involved in the original campaign against radar installations in Pembrokeshire. “What makes them think we will accept it now?”

What happens next?

A planning application for the DARC facility is expected to be submitted later this year. If approved, construction could begin in late 2026, with the radar becoming operational by the end of the decade.

The MoD has stated that it will work closely with Pembrokeshire County Council and relevant environmental bodies to ensure compliance with planning and environmental regulations. However, with strong opposition from local groups, further protests and legal challenges are expected in the coming months.

As the debate continues, the people of Pembrokeshire find themselves at the centre of a complex discussion on national security, environmental conservation, and the future of space warfare. Whether the radar station will be built remains uncertain, but what is clear is that the battle over its approval is far from over.
