What an absolute BEAST of a piece of machinery this is!
The Scud is a mobile, Russian made, short range, tactical ballistic SAM system. The SCUD series guided missiles are single-stage, short range ballistic missiles using storable liquid propellants.
At launch, a basic Scud contains about 3,500 kilograms of IRFNA and about 1,000 kilograms of fuel. Most of the IRFNA and fuel is used within the first 80 seconds of flight when the missile is gaining enough speed to reach its target, then the Scud shuts off its engine by shutting off the propellant tanks. The unused propellants - roughly 150 kilograms (330 pounds) of RFNA and 50 kilograms of fuel remain on board for the remainder of the flight.
If you are interested in this collossus - the rarest of pieces of kit; make sure you check with the boss (the wife!) first and make sure that it will fit on your driveway!
The Scud is derived from the World War II-era German V-2 rocket. SCUDs have movable fins. Warheads can be HE, chemical, or nuclear, and the missile, launched vertically from a small platform, with a range of 300 km. Unsophisticated gyroscopes guided the missile only during powered flight - which lasts about 80 seconds. Once the rocket motor shuts down, the entire missile with the warhead attached coasts unguided to the target area. Consequently, Scuds had notoriously poor accuracy, and the farther they flew, the more inaccurate they became. The SCUD series of missiles gave the Soviet front and army commanders an integral nuclear weapons capability. Non-nuclear variants of the SCUD missiles have been exported to both Warsaw Pact and non Warsaw Pact nations.
The SCUDB replaced the JS3-mounted SCUDA, which had been in service since the mid-1950s.
The longer range SCUD B, also known as SS-1c, can be distinguished by the one meter greater length of the missile and the presence of two air bottles on the side of the superstructure in place of the single bottle used for the SCUD A missile.
The SCUD B used unsymmetrical dimethylhydrazine (UDMH), a more powerful (and toxic) fuel than the kerosene used on the SCUD A, which required an engine redesign. They were transported originally on a heavy-tracked vehicle based on the JS heavy-tank chassis. This vehicle serves also as an erector and launcher for the missiles. The SCUD-B was introduced on the JS-3 tracked chassis in 1961 and appeared on the MAZ-543 wheeled chassis in 1965. The SCUD B missile appeared on a new transporter-erector-launcher based on the MAZ543 (8 by 8), giving much great choice in selecting off road firing positions.
