Introduced in 1980 in response to American advances in cruise missile technology, the SA-10 missile system was able to hit targets as low as 25 m while still retaining the ability to intercept aircraft at much higher altitudes. The upgraded SA-10c missile now allows the system to engage targets as low as 10 m in altitude. An all-weather system, the SA-10 can engage up to six targets simultaneously, at all altitudes, including ballistic missiles. Grumble systems, with their long range and large warheads, are often deployed to defend high value targets and areas.%n
