The government has fast-tracked the purchase of a €500 million air defence system that includes advanced drone-jamming technology so that part of the system can be installed before Ireland assumes the EU presidency.
Officials say the upgrades are intended to safeguard high-level meetings that could be targeted by hostile states during the presidency term.
Ireland will hold the presidency of the Council of the European Union for the eighth time from July 1 to December 31 next year. Security planners have warned that the rotating presidency — during which Ireland will host a large number of ministerial gatherings, summits and diplomatic events — will make the country an attractive target for foreign interference, making rapid enhancement of air defence capabilities a priority.
The new technology will create no-fly zones for unmanned aircraft, reducing the likelihood that Defence Forces personnel would need ministerial approval to shoot down a drone over sensitive locations. Shooting down a large drone would also pose a risk to public safety.
Officials say this protective envelope will be particularly critical around venues hosting EU presidency meetings, including sites close to Dublin airport and large government buildings.
One area of vulnerability identified by Irish authorities in relation to the EU presidency is maritime activity in the Irish Sea. There is growing suspicion that drones have been launched from vessels passing near EU capitals, although no conclusive evidence has emerged.
Dublin airport’s close proximity to the sea may result in increased searches of maritime traffic at key moments during Ireland’s presidency to ensure that hostile drone operations cannot threaten official events or delegations. For this reason, important meetings, which may be attended by high-risk targets such as President Zelensky of Ukraine, might be held outside the capital to ensure they can be adequately protected.
The investment announced on Saturday by Simon Harris, the minister for foreign affairs and defence, marks the largest defence outlay in the history of the state and comes amid concern across Europe about suspicious drone activity. The government envisages its air defence and radar system will help to safeguard not just Ireland but Europe’s western borders from Russia and hostile actors.
At least 15 Nato countries have reported incursions in recent months, with Germany and Belgium worst affected. More than half the sightings have occurred near airports and a quarter over military or strategic infrastructure, prompting fears of a co-ordinated hybrid warfare campaign.
Ursula von der Leyen, president of the European Commission, has described the activity as an “escalating campaign”, while Friedrich Merz, the German chancellor, has directly accused Moscow. The air defence and radar system acquired by Ireland comprises both land-based long-range primary radar and anti-drone capability, according to defence sources. It also includes the development of a secure air operations centre, to be based at Casement Aerodrome in Kildare.
Security sources have indicated that, once operational, the radar capability will provide air surveillance up to 15km into Ireland’s airspace. A French company will provide the contract to build and install the radar system.
