I know personally one of the original engineers on the Lynx project back in the early 70s and one of the main problems was the Gem engines. Now with LHT engines, should be ok.
Recalling a visit to McAlpines / Eurocopter UK back in 03, was given a mini poster depicted Future British Military Helicopters,where they had artists impression of EC-635/EC-145/AS-355N/EC-155/AS365-N3 in FAA/AAC/RAF colours as well as the existing COMR FOST AS-365N, DHFS AS-350, the old 32 Sqn AS-355.
Its a wild shot but maybe the EC-135/635 could do as a reccie/possibly light attack role and something like in the class of the AW-149 or S-70 could do the LBH role?
