€7 million de Havilland Twin Otter arrives from Switzerland, flies first mission near Dundalk and Cavan
Ireland’s new garda surveillance aircraft has arrived and conducted its first flight—a patrol near the border region this morning—The Journal has learned.
The de Havilland Canada-6 Twin Otter Guardian 400 arrived from Switzerland on Saturday to its base at the Irish Air Corps’ Baldonnel facility in southwest Dublin.
The aircraft was flying this morning on a route over Dundalk and north of Cavan along the Irish border, though it remains unclear whether this was an operational mission or training flight.
The Twin Otter will be piloted by Air Corps personnel with gardaí from the secretive Garda Air Support Unit (GASU) acting as spotters onboard. It joins the garda helicopter, also flown by the Air Corps, in providing aerial surveillance capability.
The new plane replaces the Britten-Norman Defender, which reached the end of its service life. The project cost approximately €7 million, including the aircraft and surveillance technology.
Sources said the Twin Otter was chosen because its high-wing design provides superior observation capabilities compared to the Irish Air Corps’ PC-12 aircraft, which garda assessors deemed unsuitable despite being equipped with surveillance equipment.
The aircraft was outfitted in Austria with cameras and other surveillance technology. Sources indicated the onboard technology includes high-end policing equipment such as phone tracking capability, advanced cameras, and systems for monitoring shipping traffic.
A tendering competition is underway for civilian contractors to maintain the aircraft at Casement Aerodrome and other unspecified locations.
Garda tender documents state GASU’s primary mission is providing patrol and response capability through “visual contact flights.” The aircraft will operate day and night to “identify a target, establish and maintain visual contact with the target.”
The border patrol route on the aircraft’s first operational day suggests priorities include monitoring cross-border criminal activity, organized crime operations, and potentially security-related intelligence gathering in the sensitive border region.
The Twin Otter’s arrival enhances garda aerial surveillance capabilities at a time of heightened concerns about organized crime, drug trafficking, and cross-border smuggling operations. The advanced technology package enables real-time tracking and intelligence gathering to support ground operations.
An Garda Síochána has been contacted for comment but had not responded at time of publication.
The deployment represents significant investment in garda aerial capabilities, providing modern surveillance technology to support law enforcement operations across the country, with particular utility along the extensive and often rural border with Northern Ireland.
