Early phases of MX development - 1976

I've already mentioned the attached diagram in anumber of posts. Now I've finally unearthened it. It is a freeze-frame of the status of advanced ICBM concepts (not to be confused with AICBM WS-120A) considered by USAF between 1975 and 1976. You'll find relevant information on the individual concepts in the diagram caption. UMX was in direct competition with what became D-5. BTW, Titan-2 had a throw weight of 8,200 lbs.
