Launch warning times.

Assuming the missile hits on Thanksgiving Day were all from ground-based launchers within Russia's borders (unlikely; you could do the TDM strikes with a pair of Typhoon-class boats, one in the middle of the pacific and another in the middle of the Atlantic), what, roughly would be the length of time between detection and impact?

BMEWS/DEW would be suppressed at least somewhat by the EMPs used (which may have been decoy/dummy satellites with warheads detonated on pass-overs over the CONUS), but that would still put CONUS and OCONUS stations on Launch-On-Warning, would it not?
