> Given satellite technology and ICBMs I see an SR-72 being a hedge against losing both of the above, or having them rendered ineffective. Putting a nuclear munition on this thing makes sense to kind of get ICBM like capability in a ditch, and ensures you have something against the enemy who can reliably intercept ICBMs. Same for the case spy sats get taken down. The chance of the enemy having something that can intercept high speed aerodynamic targets, as well as satellites at the same time is minimal.
