Reminder that money is not important to the US war machine. The US in practice at the levels we're talking about can create as much as it needs to sustain its military machine. It's about production capacity, raw materials, lead times, production time, etc.
US would have to be making and losing hundreds of these a year before the finances of the fact would hit home (US "defense" budget is near a trillion dollars so 10% more or so wouldn't really register). On the other hand if they can only make a few every few years then every loss really hurts especially if they can't scale capacity due to constraints in some part of the production or supply lines.
