As far as I know existing silos and control centers are being renovated. I haven't seen hot launch confirmed but it seemed likely. The missile appears to be more MMIII in size and arrangement than the MX, which was cold launched from MM silos because it was too large for a hot launch in the existing infrastructure.Skipping from MQM-178 to AIM-260 did suggest that might already be the case, to be fair. It was at least possible that there were 80-odd classified designations, if unlikely.Looks like even the missile designation system is broken now too.
Notwithstanding silly designations, the USAF illustrations are interesting if accurate. They suggest that the missile may be installed in new, hot-launch siloes, with new launch control centres. That's a significant step away from Minuteman, and indicates substantially different missile capability and survivability.
It doesn't look like the new missile is a dramatic change in capability or throw weight to me.
