With invention of gun powder back in 9th century,
military technology has mainly evolved to use it for longer range, higher
accuracy and faster speed. Initially there were guns & canons. Later
rockets were developed for longer range and better accuracy.
Though the date of first use of rocket is highly debated
some historians consider the first use of rocket as way back as in 1232 by the Chinese against
the Mongols. Early text describes use of first multistage rockets in the 14th
century.
First use of Metal cylinder rocket artillery was used by
Tipu Sultan in the 1780s during the Anglo-mysore wars against the British army.
This rockets had a range of 2 Kms. V-2 rockets developed by Nazi Germany was
the first of the modern day rockets. First produced in 1943 V-2 rockets had a
range of 300Km and with later developments increased it’s accuracy to few
meters.
Post Second World War with the introduction of Nuclear weapons
and space programs rocket were needed to be of much longer range and absolute
accuracy. During the Cold war both USA and the Soviet Union invested heavily on
developing Rockets(missiles) to counter each other, hence led to the
development of the Intercontinental Ballistic
Missiles (or ICBMs).

During this phase Soviet Union developed arguably the
most deadly missile of all time - the R-36M series (NATO Name SS-18 Satan).Just
to understand the deadliness of this ICBM – The nuclear Bomb used in Hiroshima (which
took 70,000 human life)was of 15 KT yield while a single SS-18 carries nuclear
warhead of 20000KT i.e 1333.33 times more powerful.
SS-18 is the heaviest of any missile ever built with a max
weight of 211000kg and a range of 16000Km which is also the longest range for any
missile ever built by human. This missile have the highest throw-rate of 8,800
kg(In comparison to LGM-118 Peacekeeper
which had a throw-weight of 4000kgs).
First introduced in 1967 this silo launched MIRV (multiple
independently targetable reentry vehicle) is capable of carrying 10 warheads(In
comparison Minuteman carries 3 warheads) and up to 40 penetration aids (like
decoys, radar jammers, chaff etc).
Comparison of US & USSR ICBMs |
SS-18 have a lower accuracy (220-700m) than their US
counterparts but when you are deploying a 20MT nuclear device the accuracy does
not matter much.
At its peak 308 SS-18(61,60,000 KT) launch silos were
operational in 1991.In July 2009 only 59 (all 10 MIRVs) of these are operational
i.e a total yield of 11,80,000 KT of TNT.
A SS-18 Silo |
The SS-18 was deployed in modified SS-9 silos, and
employed a cold-launch technique with the missile being ejected from the silo
prior to main engine ignition. These specially hardened silos are 39 meters
deep and had a diameter of 5.9 m. According to Western estimates, the SS-18 was
deployed in a silo with a hardness of at least 4,000 psi, and possibly as high
as 6,000 psi (In comparison American missile silos are hardened to 300 psi)
