The launch of the 9K720 Iskander and OTR-21 Tochka during the Ukraine War, probably contributed to stimulating the development of the world missile industry, especially ballistic missiles. As is known, a few years ago, Indonesia pioneered the construction of a ballistic missile prototype, which later became the R-Han 450 short-range ballistic missile. The Rhan-450 is a surface-to-surface missile with a range of over +100km, developed from the Sonda rx450 base rocket made by the Indonesian Space Agency.
On December 16, 2016, R-Han 450 was successfully launched with a distance of 150 km. In 2022, the Rhan-450 program has entered the 2nd of 4 stages of development and is expected to continue until 2027 until it is ready to enter the mass production stage. in 2023-2024, Indonesian research institutes will develop high energy propellant (rocket fuel), composite rocket tubes and heat insulation technology, as well as guidance systems and missile control systems which will be integrated into the RHAN-450 Missile to increase the range Up to 200 km.
From the specifications, the R-Han 450 is expected to reach a maximum altitude and range of 44 km and 129 km respectively if fired at an elevation angle of 70 degrees. Apart from acting as a ballistic rocket for military purposes, the RX-450 base is also planned as part of a multilevel rocket that will be used as a Satellite Orbiting Rocket (RPS).
The R-Han-450 can carry a payload weighing 50 kg – 100 kg. In fact, the R-Han 450 is a type of ballistic rocket with a total length of 6.11 m, a motor length of 4.459 m, a total weight of 1,500 kg, and uses a composite propellant fuel. This rocket was previously known as the RX 450; the name then changed to the R-Han 450 and the increase in capability in the ballistic rocket was expected to be mass produced in the interests of both domestic and commercial defense. If successful in mass production, this will help fuel a regional trend in ASEAN: the large-caliber tactical missiles.
