If their budget gets cut, then they will be concerned.

They don't care about the satellites either. They care about the relationships. What they're buying and how much it actually costs is irrelevant compared to who they award the contract to. The big contracts really do have to get awarded to the right people or reelection becomes impossible.

I would wager that they may not care so much about reducing their annual costs, but they probably do care about per-mission costs. If they can cut their per-unit costs in half, then they can have twice as many toys without having to convince Congress to give them more money.
