Weeeelllll,
No, I don't think aircraft would have been on the agenda. Unless the Irish govt were prepared to make a serious contribution to an airlift or heavy helicopter capability. Otherwise, I reckon improvements in radar coverage and tactical support packages were more likely, cos they are cheaper and more flexible. With a FARP or FOB capability, the loggies would be in great demand! With a tactical radar and TACP/CAS facility coupled with this, the Irish may become serious movers in low level conflicts. In addition, more expenditure on ground capabilities, such as proper armour and AD assets would again be cheaper and provide a bigger fist in any EU BG.
