Mr. RFH, Roamy’s husband (and an honest-to-goodness rocket scientist himself) remarked on the abort motor for the Orion crew capsule in the last post.
Wonder what he thinks of the Hercules X-265 motor on the old Nike Sprint ABM platform. 650,000lbf, 0 to Mach 10 in 5 seconds, 100g of acceleration. THAT’S a motor…
Spartan/Sprint was a two-layered anti-ballistic missile system to shield the US from a Soviet ICBM strike. It worked, and was actually deployed, but there were problems. One, the system was really expensive. Two, the US and the Soviets signed the ABM treaty which really curtailed the usefulness of ABM systems. And three, the use of nuclear warheads to destroy incoming nuclear warheads wasn’t all that popular an idea, and it had some real practical drawbacks, especially in terms of EMP.
