Mk72, Mk104, Mk136, 3km/s cutoff. Range ~460nmi, ceiling 550km. Flight endurance is about 370s.
Such booster would be able to intercept IRBM like DF-26, but (see below Blk IB) would be limited by platform/GNC/KV and is only MRBM (3000km) capable. The same booster enabled ASAT (see below Blk IB) but not for I/IA for the same reason.
KV side:
LEAP
Solid divert motor, no throttle.
Similar to Orion spacecraft launch abort system attitude control system.
One color IR seeker, 15nmi range.
Discrimination/speed penalty if possible, range comparative to PAC-3/THAAD seeker.
PoK: 80% suggested plus speed/angle penalty modifications as appropriate, would suggest ~65% for a MRBM (all head to head midcourse/after apogee interception).
SM-3 Blk IB
Booster side:
Same as I/IA.
IRBM (5500km), ASAT capable.
KV side:
Solid divert motor, throttleable.
Two color IR seeker, 30nmi, advanced signal processor.
Higher/more precise divert, discrimination, can handle higher speed.
PoK: 90% suggested plus speed/angle penalty modifications as appropriate, would suggest ~85% for a MRBM, 75% IRBM (all head to head midcourse/after apogee interception).
Booster side:
Mk72, Mk104, Mk136, 3km/s cutoff. Range ~460nmi, ceiling 550km. Flight endurance is about 370s.

Booster side:
Mk72, 21in SRM, 21in SRM. 4.5km/s cutoff, Range 1400nmi, ceiling 1400km, flight endurance 700s.
KV side:
High divert KV, ~twice the diameter.
Discrimination IR seeker, 45nmi.
PoK: 95% base, >90% MRBM (what a waste), 85% IRBM, 75% ICBM (all head to head midcourse/after apogee interception).
