Contrary to the partisan memes, support for military funding is actually bipartisan. Republicans often like to say that Democratic politicians don't support the military, to pander to their base, but this isn't actually true. And Democratic Party sometimes like to play at being peaceniks, again to pander to their base, but this isn't true either.

Look up the composition of the United States Senate Appropriations Subcommittee on Defense. 50/50 split between parties. You don't get DoD projects funded by sucking up to Republicans, you need to convince politicians on both sides of the aisle.
