A1 Interceptor

There are two A1 interceptor versions. The A1A executes interceptions at extremely low altitudes (100-200m) to combat ground and underground detonations of conventional and nuclear warheads. The A1B executes interceptions at low altitudes (1,000-2,000m) to combat air burst warheads of conventional and nuclear warheads. The A1A and A1B can work individually or in conjunction, creating a layered defence system. This option is required by the Defended Area (DA) type featuring underground or surface assets, which determine the incoming missile warhead detonation height, at ground or underground level, or air burst. Another criterion for choosing between A1 version over a DA is the incoming threat type, conventional or nuclear.
