TBH LJ, I was more "zoomed out" than that (not implying there is anything wrong with what you posted at all).
Cliffs:
The defence procurement in question was agreed by a leadership team (Cameron/Osborne) no longer at the helm.
It was part of a Government Spending Plan that has now been very publicly binned.
It was (in the eyes of many authoritative commentators) un-deliverable anyway.
It has been replaced by...who the **** knows?
The UK economy (and its ability to create wealth/spending power) is clouded in uncertainty.
All the US procurement related costs (eg P8) might* have just increased by 10-15%
[*might, because I'm not privvy to contractual small print on currency fluctuations]
Trump is throwing a cloud of uncertainty over a cloud of uncertainty (so a sort of uncertainty squared, if you will).
This is defense procurement people...where the words "on time and on budget" rarely co-exist.
Happy **** ing New Year.
