We probably should have interceptors but it will never happen. The budget simply isn't there. As it was explained to me once, it's not so much the aircraft themselves as the lack of a dedicated military radar. The figure of €200 million was mentioned just for the radar. Then you need aircraft, missiles, training, support equipment etc. It's just not a viable option.
That all raises the question of what kind of Air Corps we should have? On another forum the role of the Air Corps was seriously questioned. It was pointed that most of it's roles could be done more cheaply by civilian contractors just like SAR is done now, particularly the governments jets. The PC9s seem to be a very expensive way of training pilots to fly Cessnas and helicopters. Maybe the best job for the Air Corps should simply be to get more helicopters to support the army and do away with most of the rest of it's jobs. It's an interesting thought, if not very comfortable for those of us who are interested in the Air Corps.
