The use of rocket artillery dates back to medieval China where devices such as fire arrows were used (albeit mostly as a psychological weapon).
The first true rocket artillery was developed in South Asia by Tipu Sultan, the ruler of the Kingdom of Mysore.
In the late nineteenth century, due to improvements in the power and range of conventional artillery, the use of early military rockets declined; they were finally used on a small scale by both sides during the American Civil War.
The use of rockets as some form of artillery dates back to medieval China where devices such as fire arrows were used (albeit mostly as a psychological weapon).
The use of medieval rocket artillery was picked up by the invading Mongols and spread to the Ottoman Turks who in turn used them on the European battlefield.
[2]: 48 Mughal ban iron rockets were described by European visitors, including François Bernier who witnessed the 1658 Battle of Samugarh fought between brothers Aurangzeb and Dara Shikoh.
According to Stephen Oliver Fought and John F. Guilmartin, Jr. in Encyclopædia Britannica (2008): Hyder Ali, prince of Mysore, developed war rockets with an important change: the use of metal cylinders to contain the combustion powder.
Although the hammered soft iron he used was crude, the bursting strength of the container of black powder was much higher than the earlier paper construction.
Although individually these rockets were not accurate, dispersion error became less important when large numbers were fired rapidly in mass attacks.
His rockets were more elongated, had a much larger payload, and were mounted on sticks; this allowed them to be launched from the sea at a greater range.
The original rocket design had the guide pole side-mounted on the warhead, this was improved in 1815 with a base plate with a threaded hole.
The British engineer William Hale designed a rocket with a combination of tail fins and directed nozzles for the exhaust.
This imparted a spin to the rocket during flight, which stabilized its trajectory and greatly improved its accuracy, although it did sacrifice somewhat of the maximum range.
By the late nineteenth century, due to improvements in the power and range of conventional artillery, the use of military rockets declined; they were finally used on a small scale by both sides during the American Civil War.
The Soviet Katyushas, nicknamed by German troops Stalin's Organ because of their visual resemblance to a church musical organ and alluding to the sound of the weapon's rockets, were mounted on trucks or light tanks, while the early German Nebelwerfer ordnance pieces were mounted on a small wheeled carriage which was light enough to be moved by several men and could easily be deployed nearly anywhere, while also being towed by most vehicles.
The Germans also had self-propelled rocket artillery in the form of the Panzerwerfer and Wurfrahmen 40 which equipped half-track armoured fighting vehicles.
On Iwo Jima, the Marines made use of rocket artillery trucks in a similar fashion as the Soviet Katyusha, but on a smaller scale.
Their deployment was limited relative to other mortar types and the projectiles on the 40 cm launcher were so large and heavy that they had to be loaded using small hand-operated cranes, but they were extremely accurate and had a pronounced psychological effect on opposing troops, who called them "Screaming Mimis", a nickname originally applied to the German Nebelwerfer tube-launched rocket mortar series in the European Theater of Operations.
