RIM-161A is designed to intercept ballistic missiles outside atmospher (so its range and speed) but couldn’t work against anything else. As RIM-156 was cancelled, it let only the SM-2 block IV and Evolved Sea Sparrow Missile on the american side. Both decent SAM but with shorter ranges than its european counterparts.

What are you smokin’? The SM-2 Block IV has a 240 km range. No European SAM comes anywhere NEAR that. S-300 doesn’t either. The SM-6 (which is essentially a Block IV with AMRAAM’s active radar for terminal homing) will be further still. ESSM has a range of over 50 km and only the long ranged version of ASTER beats that for European SAMs. As for SM-2 MR even the ANCIENT Block I was good for over 70km. Current Block IIIBs most likely have a MUCH longer range.
