The Garda Air Support Unit (GASU) is a unit of the Garda Síochána which was formed in 1997. The GASU is part of the Operational Support Unit, which provides specialist support to Gardaí nationwide. The Operational Support Unit also includes the Water Support, Dog Support and Mounted Support Units.

Between 2007 and 2008, the unit released figures indicating that it had contributed to 1,300 arrests within the preceding three years, and it had located 14 people during search and rescue operations in 2007.

Aircraft

The GASU's aircraft are maintained and flown by the Irish Air Corps, and based at Casement Aerodrome near Dublin.

As of December 2025 the unit operates two EC 135 T2 helicopters and a Viking Series 400 Twin Otter.

They formerly operated a Eurocopter AS355N Squirrel (Eceuriel) helicopter, which was in use by the unit from 1997 until January 2008, when the second EC 135 T2 replaced it. A Britten-Norman Defender, in operation since 1997, was placed into storage (pending disposal) in November 2023 and was replaced by the Twin Otter. The Squirrel and the Defender were the first two aircraft of the unit.
