The Ministry of Defence has issued a detailed update on its ongoing security overhaul, setting out new surveillance systems, restricted airspace trials and efforts to rebuild guard and policing capacity across UK military sites.
In a written statement to Parliament, Armed Forces Minister Al Carns said the department had continued to increase security measures after identifying serious weaknesses across the estate.
Carns opened by saying “we have identified the physical security of our sites as an area in need of greater focus” and that the MoD was using in-year funding to upgrade priority locations. He added that the department had “maintained our posture of enhanced vigilance and continue to strengthen our security culture”, including updated guidance and easier reporting routes for personnel and contractors.
A major part of the update focused on new surveillance technology. Carns said the RAF had made “significant progress in strengthening security through advanced technical enhancements, now operational at multiple main operating bases”. The Immediate Threat Mitigation Solution, a deployable CCTV system able to detect and track intrusions, is already in service.
At RAF Brize Norton, Carns said the upgraded systems “enable faster decision making and improve the Military Provost Guard Service’s ability to respond swiftly and effectively to incidents”. He also highlighted closer cooperation with Thames Valley Police and local landowners to boost perimeter reporting.
Airspace restrictions form the next phase, the MoD will “pilot restricted airspace above 40 strategic sites”, describing it as a precursor to national rollout in 2026. The aim is to reinforce restricted-place powers under the National Security Act and improve detection of malicious drone activity. He added that the MoD is “significantly investing in remote piloted aerial systems… to help deter threats and identify them when they arise”.
Manpower remains a critical issue, Carns said the MoD had “taken decisive steps to improve recruitment across MOD Police, MOD Guard Service, Military Provost Guard Service, and Security Services Group”. Incentive schemes for the MPGS have been successful and similar measures are under consideration elsewhere, alongside more targeted advertising and better candidate engagement.
Carns said the £20 million investment in modernisation is being directed to “three flagship systems to modernise defence security”: a critical national infrastructure knowledge base, a new incident case-management system and a real-time physical security assurance platform.
Looking ahead, Carns said “ensuring the safety and security of the defence estate continues to be a key priority”. He warned that “all those who seek to threaten the security of our bases should be in no doubt that we will use all the levers at our disposal to take swift action”, adding that the department “will not hesitate to pursue prosecution where criminality is suspected”.
The update confirms that the security overhaul is now moving beyond immediate fixes toward a longer-term systemwide rebuild, with further announcements expected as new technology and airspace measures are brought online.
