I don't know if we'll hit 2%, but there is a ludicrous amount of things that were greenlit this year 6-9 months ago that is still rolling in this FY, so it's less 'March madness' and more time lag, with a lot more coming, when the O&M pursestrings were somewhat restored and large backlog of required parts started getting ordered. Also a lot of ongoing repairs to things that have been falling apart for decades with RPOps going nuts with minor cap projects. The big thing slowing it down is just capacity (both our internal and actual construction capacity)
A lot of it is also just big projects starting to deliver, with things like all the infra for F35 starting construction (and payments going out) over the next few years, CSC long lead items and a lot of other expensive bits for programs.
2% is a bit of a random goal, but hard to argue that they aren't spending a lot on defence, and it's increased significantly in the last year.
