Henry,
The very summarised description says:
"When TT is initiated by the guidance system, a firing signal is sent
through the A/D device to the LSC. A plasma jet from the LSC cuts through
the motor case, allowing the motor combustion gases to escape through the TT
stacks."
Any more information on how that "plasma jet" works?
Thanks,
Troy

No, all three operational Minuteman versions had thrust termination on the
third stage, to improve insertion accuracy (although on Minuteman III the
requirements were relaxed a bit because the liquid-fuel MIRV maneuvering
stage could do final velocity trim). See attached excerpts from a slide
about Minuteman hardware (which refers only to Minuteman II and III
because it was written after Minuteman I was retired).
