Do you have any thoughts on where this might be going or what programs, if any, are in the pipeline?
In the *US* pipeline? If recent years (say, the last 40 of 'em) are any guide, damn near nothing that will actually come to pass as an intended program. There is always work going on to design the Next Great Reusable Rapid Reaction Launch System... just as there has been for about as long as I've been alive, with little to show for it. However, there may be a lot of systems sort of sneaking up that'll do the job... SpaceX for space launch and various smallsat/nanosat technologies to replace military satellites that "near-peers" are or will be soon able to take out at will.
Space is currently used for recon, communications and navigation. So far as anyone knows, it is not used for weapons, and there's no evidence that that's going to change anytime soon for the US. SpaceX and Blue Origin *may* be able to provide the ability to reasonably rapidly replace satellites used for recon, comms and nav. The X-37 seems to be related to that, though what advantage it would actually provide in wartime is unclear.
