“According to DID,

“SM-2 has recently completed an upgrade that gives it improved maneuverability via improved steering, thrust-vectoring, and software. This is especially important against supersonic wave-skimming cruise missiles, which offer very little time from the moment they break the horizon to become visible on radar until impact.”

Where it’s got that long-burn motor that’s an interesting developement. Too bad they only buy what, twenty or thirty a year? :rolleyes:
