The Jericho II is 14.0 m long and 1.56 m wide, with a reported launch weight of 26,000 kg (although an alternative launch weight of 21,935 kg has been suggested). It has a 1,000 kg payload, capable of carrying a considerable amount of high explosives or a 1 Megaton yield nuclear warhead. It uses a two-stage solid propellant engine with a separating warhead. The missile can be launched from a silo, a railroad flat car, or a mobile vehicle. This gives it the ability to be hidden, moved quickly, or kept in a hardened silo, largely ensuring survival against any attack. It has an active radar homing terminal guidance system similar to that of the Pershing II, for very accurate strikes.
