I am wondering why the SPRINT missle was scrapped. It is a counterpart to the Spartan Antiballistic missile of the 60's. The SPRINT missle is a high speed terminal defense missle. In my opinion this is an exceptional missle. Is there a superior missle that has replaced it? Or is the technology obsoloete. Current Antiballistic efforts rely on intercepting a missile in the Boost, and Midcourse phase, but I have yet to see a terminal phase project. I believe that terminal interceptors are needed for the simple reason of what if one of the buggers gets through. Not only that, the terminal interceptor will not have to distinguish from decoys because only the true war heads would be entering the atmosphere and acquiring the target. Any thoughts or comments.

Don't forget that the 1972 ABM treaty essentially ended these type missiles for the U.S. The whole system was quite impressive for the day and accuracy was less important that speed esp if equiped with a small nuclear warhead.
