The 9K720 Iskander (Russian: «Искандер»; NATO reporting name SS-26 Stone) is a mobile short-range ballistic missile system produced and deployed by the Russian military. The missile systems (Искандер-М) are to replace the obsolete OTR-21 Tochka systems, still in use by the Russian armed forces, by 2020.^[10][11] The Iskander has several different conventional warheads, including a cluster munitions warhead, a fuel-air explosiveenhanced-blast warhead, a high explosive-fragmentation warhead, an earth penetrator for bunker busting and an electromagnetic pulse device for anti-radar missions. The missile can also carry nuclear warheads.^[1][12][13] In September 2017, the KB Mashinostroyeniya(KBM) general designer Valery M. Kashin said that there were at least seven types of missiles (and "perhaps more") for Iskander, including one cruise missile.^[14]
