Do you think that there is a shortage of ICBM's? Do you think that ICBM's can no longer be made (by the U.S. or our potential enemies)?
Moreover, *why* do you keep asking questions that have no bearing on anything?
Dynasoar is a dumb idea for an air superiority fighter. It takes one ICBM for one dynasoar, minimum. So, for a fleet of 500, we would need 500 ICBMs, and all their attendant launch facilities and maintenance.
It is a STOOOOOOOOOPID idea, you keep bringing up.
Since we need some more tanks, why not get some new Indy cars? They go a lot faster. And we could get some racing yachts to replace our destroyers, since they go faster.
