Ah, the huge dilemma of Procurement and one that we can expect this government to ignore. All 3 services are using up the fatigue life of a wide ranging number of "capabilities" from Land Rover to helicopters to FJ and ME aircraft. Let's not talk about the rate personnel are being used up. There can be no doubt that a number of the fleets, and we could probably name them all on here, will be "getting older" at a faster rate than ever envisaged, or more importantly planned for. The EP cannot bring forward the replacements, everyone knows how broken the EP is.
OSDs will come forward, attrition will continue at a higher rate and yet there is no way of replacing those fleets that are rapidly getting worn out. Not without a MASSIVE increase in the Defence Budget - and I can't see GB allowing himself to be "outrun by [us] military bastards" and provide more money to Defence.
