I based three on the set up here in Wales, roughly comparable areas to cover though I think Ireland is bigger. At present covered here by two ec 135T.2+ aircraft and one bolkow they are planning to replace with a third 135. I can tell you the aircraft are pretty busy. I did not like to say it, but also feel the military in Ireland is pretty dismal, and remeber when they did SAR they did not have crew to put a dauphine out one year for somebody missing in the sea off howth, then got upset and posessive when the contracts went out to private companies to tender. In my opinion they were better when they had the alouettes, but became complacent when all the new kit arrived. What the heck do they use thier fleet of 139's and 135's for anyway?
