Ireland to Install First Radar System Capable of Detecting Stealth Aircraft by 2026

Ireland is preparing to take a major step in strengthening its national security with the introduction of its first primary military radar system designed to detect aircraft built to avoid traditional detection methods — including those equipped with advanced stealth technology. This modern defense capability is expected to enhance Ireland’s ability to monitor and protect its airspace, particularly at a time when global and regional security challenges are on the rise.

Defense Minister Simon Harris confirmed that the new radar system is scheduled for rollout in 2026. He highlighted the importance of this move, explaining that it would significantly improve the Irish military’s ability to detect not only stealth aircraft but also planes that might be hijacked or deliberately flying without transponders — a common method used by smugglers and other illicit groups.

At present, Ireland does not have the capability to independently monitor such airborne threats in its airspace. The installation of this new system will fill that critical gap, ensuring early detection and real-time tracking of any suspicious or hostile aircraft operating within or near Irish-controlled skies.

Why This Radar Matters

The decision to deploy a primary radar system first surfaced in 2022, following a recommendation from Ireland’s Commission on the Defence Forces. This was part of a broader plan to modernize the country’s defense infrastructure, ensuring it keeps pace with modern threats and integrates smoothly with existing military resources.

Although Ireland is not considered a direct target in current global conflicts, government officials have repeatedly stressed the importance of enhancing national security, given the changing geopolitical landscape. Defense Minister Harris remarked that in today's unpredictable security environment, no nation, including Ireland, is completely shielded from potential threats.

Radar System Specifications and Features

While the exact model of the radar system has not been publicly disclosed, some general details about its expected capabilities are known:

• Primary Surveillance Radar (PSR): Unlike secondary radar systems, which rely on signals from aircraft transponders, this radar will actively scan the skies for any object, including those with transponders turned off or stealth-designed aircraft that attempt to avoid detection.

• Stealth Detection Capability: The system will be equipped with advanced signal processing technology to detect low-observable (stealth) aircraft, which use special shapes and materials to reduce their radar cross-section (RCS).

• Long-Range Coverage: The radar is expected to cover both Irish sovereign airspace and parts of its surrounding air control zone, providing early warning for unidentified or unauthorized aerial activity.

• Integration Ready: It will be designed to connect seamlessly with Ireland’s broader air defense and civil aviation monitoring systems, enabling quicker responses and coordinated action if necessary.

• Operational Timeline: The radar system is projected to be installed by 2026 and fully operational by 2028.

A Timely Move for a Changing World

This radar installation marks a vital step in Ireland's ongoing efforts to bolster its defense readiness. In recent years, the importance of national airspace monitoring has become increasingly clear, especially as new stealth aircraft and unmanned aerial vehicles (UAVs) enter global military arsenals.

The development also comes as many European nations upgrade their early warning and air defense capabilities, given the unpredictable security situation in regions like Eastern Europe and the North Atlantic.

Once operational, this new radar will stand as one of Ireland’s most important national security assets — providing a modern shield over Irish skies and ensuring that the nation is better prepared to face future challenges.
