Gazelle does at least 5.5km/s.

  But how long does it take to get to that speed?

    By the time its left the silo. Russians are dead keen on their one-shot silos packed to the gills with various devices (pneumatic, hydraulic, explosive) to bring a missile up to ludicrous speed very, very quickly. Spent a very enlightening afternoon down an old bunker near pervomaisk. Found some stats in the tourist brochure from there. 9.4m high,1.1m dia, 4km/s in 4s, which gives an acceleration if about 102g. 80-100km range. Max speed 7km/s. "directional blast" also, which is interesting.

      The US Nike-X Sprint had similar performance (Wikipedia says only 90 gravities, and there's some nonphysical-looking footage of test launches on youtube somewhere). Pretty crazy, and I gather that MIRVs made that whole category of ABM obsolete.

        Yup. Aforementioned satan missile can carry hundreds of warheads, and an equal number of decoys. Two of them, they said, could wipe out all US cities.
