I'm not going to defend all defense spending (and I don't know much about healthcare, though I expect it's similar), but much of the cause of huge expense for defense projects is that they're buying standard deviations. A lot of the stuff is manufactured to shockingly small tolerances. Same reason you spend $10000 for a PLC with less functionality than a $35 RBPi.
