2 kilometers per second

6500 ft/second for a missile? That seems like BS.

S-300PMU1 SA-20 GARGOYLE The S-300PMU1 is an extended range version of S-300PMU with a limited anti-ballistic missile capability, including capabilities against aerodynamic targets with speeds up to 3 kilometers/second. The S-300 PMU1 mobile multichannel air defence missile system can defeat modem and future aircrafts, strategic cruise missiles, tactical battlefield ballistic missiles and other targets with a reflection surface up to 0.02 sq. m. flying at speeds up to 2.800 m/s in massive enemy air raids and heavy clutter and severe ECM environments. This system was developed from S-300 PMU and differs from it by improved technical and operational characteristics. These improvements were achieved owing to incorporation of new engineering innovations in the S-300 PMU, based on many years of experience gained during its operation and perfection of mathematical support, using state-of-the-art computer aids. http://www.globalsecurity.org/military/world/russia/s-300pmu1.htm

That’s only Mach 2.5 or so.
