Pyongyang, May 30 (KCNA) — “Rocket” weapons were made and used by Korea already in the period of Koguryo (B.C. 277-A.D. 668).
The first “rocket” was very simple but its principle is similar with that of modern one.
A jet-propelled weapon called Kwanghwi demonstrated its might in a battle near the castle in Mt. Pukhan in 661.
People of Koryo (918-1392) made a “rocket” called Hwajon.
Hwajon was 726 millimeters long and its arrowhead 90 millimeters long. The arrow was shot by lighting the cartridge.
According to a historical record, Koryo manufactured lots of Hwajon around 1127 and deployed them in vantage points for national defence.
On the basis of arrows with fire wicks made in the period of the three kingdoms, Koreans developed Singijon, the origin of multistage rocket, in the early 15th century.
There were three kinds of Singijon according to their sizes, types and powder-cartridges.
The small one was a two-stage rocket. The medium one with one more small cartridge than the small one was a three-stage rocket, while the large one with four cartridges and wings was a four-stage rocket.
Having a great firing power, they could strike far-off targets on land and big warships. The weapons were widely used during the Imjin Patriotic War (1592) against the Japanese invaders and other battles against invaders. They were also used as signal means.
They are precious historical relics showing the intelligence and patriotism of the Korean nation.
