Hardening or mobilizing land-based nuclear assets In addition, land-based ICBM silos can be hardened. No missile launch facility can really defend against a direct nuclear hit, but a sufficiently hardened silo could defend against a near miss, especially if the detonation is not from a multimegaton thermonuclear weapon. In addition, ICBMs can be placed on road or rail-mobile launchers (RT-23 Molodets, RT-2PM2 Topol-M, DF-31, Agni 5, Agni 6, MGM-134 Midgetman), which can then be moved around. As an enemy has nothing fixed at which to aim, that increases its survivability.
