This explains why the A400M is only funded for the plumbing for fuel tank protection. The plumbing needs to be paid for this year but the ring fenced funding for the OBIGGS system will have to wait for a FY some time down the line. This is all well and good, but now that Treasury rules on UORs have changed, requiring MoD to stump up 50% of costs, what happens if a higher priority funding item comes up in the same FY as the OBIGGS is due?
Coherence and Defence Policy, words you never hear from a Labour Government.
