The selection of the EC135 as the Air Corps new LUH almost guarantees that the GASU will have Air Corps Pilots for a long time to come.If the Air Corps will cease to fly the aircraft,then they will continue to play a huge part in the Training of the Pilots,and Maintenance of the aircraft.
The tenders for the new helis mentioned FLIR as an option on the UH,so it is possible that they would wish to keep an aircraft in the Air Corps inventory capable of backing up the GASU in the event of aircraft overhaul or special security events where an eye in the sky in invaluable.However,I doubt they will be permanently based in Baldonnel for much longer. In the last few years the Helis have seen prolongued deployment to the States other major cities. Limerick had the EC135 almost permanently during the summer,and its currently to be seen in the skies of cork.
The GASU has proved itself capable of being a valuable asset in the war on crime, and local authorities and garda management outside the Capitol are keen to see these aircraft used in their locations,having seen the effectthey have made in Dublin since 1997.
The gardai want to fly their own aircraft,and indeed why shouldn't they? Do taxi drivers drive patrol cars?
