Relate significant events in society to innovations in technology

Rocket Luncher
The RPG has its roots in the 19th century, with the early development of the explosive shaped charge. The development of practical rocketry provided a means of delivering such an explosive. Research, occasioned by World War II, produced such weapons as the famous American bazooka, and German Panzer Faust, which combined portability with effectiveness against armoured vehicles such as tanks.
The Soviet Union-developed RPG-7 is the most widely distributed and used RPG in the world The Soviets developed the basic design of this RPG, in the form of the RPG-2, during World War II, combining important design features of the US Bazooka and the German Panzer Faust.

German spaced armour
An early method of defeating shaped charges developed during World War II was to fit wire mesh 10 cm or more away from the armour of an armoured fighting vehicle (AFV). Shaped charges rely on the formation of a jet of superheated copper melt to cut through armour. The mesh would trigger the RPG on contact and much of the jet that a shaped charge produces would be dissipated before coming into contact with the main armour of the AFV. Caged armour is still in use. Similar effects can be obtained using spaced armour either as a part of the original design or as appliqué armour fitted at a later date.
Today, technologically advanced armies have implemented composite armours such as Chobham armor on their tanks that protect against RPGs. Older models of tanks may be retrofitted with reactive armour that functions by causing a small explosion to blow away the molten copper used in most shaped charges.
As in all arms races, these developments in armour counter measures have led to the development of RPG rounds designed specifically to defeat these counter measures, such as those fired from the RPG-29 Vampir, a Russian man portable, shoulder fired anti-tank grenade launcher.

Because of many wars and battle the inventor makes new rocket launcher that is more dangerous and more powerful and advance. Some rocket launcher now are design to destroy specific things. Like hitting a building, destroy a country, kill all living thing in an area. This missiles also design in wars, in early ages only canons are used as messile like weapon that is use to attack long range enemies
