Shahab-3 (missile)

Shahab 3 missiles are Iranian ballistic missiles, which are the most plausible delivery vehicle for any Iranian nuclear weapon. The basic medium range ballistic missile version has a medium range of 1,300 km in its initial form. 3A and 3B versions with up to a maximum range of 2,500 km have been reported, which go into the intermediate range ballistic missile category. A 3D version may be a space launch vehicle.

While Iran has done very substantial development, the original design derives from North Korean No Dong technology. The missile is road-mobile and uses a storable liquid propellant. Its payload is at least 1000 kilograms, which is adequate for nuclear warheads based on a low-yield design from A.Q. Khan of Pakistan.

Its basic guidance is guidance, probably initially with a circular error probability of 1-3 km, which is expected to improve.
