70-mm Multiple Rocket Launcher
Originally designed for standard of firepower support for infantry regiment, the 70mm MLRS is mid-size with light weight to perform higher mobility. In 2000, the Hanwha Corporation started development, as a private venture, of a lightweight self-propelled 70 mm (40-round) multiple rocket launcher. The company had considerable experience in the design, development and production of a wide range of munitions including the 130 mm Kooryong series of unguided surface-to-surface rockets. These are launched by the 130 mm (36-round) multiple rocket system.
The 70 mm (40-round) system had already undergone trials with the Republic of Korea Army but, as of early 2008, quantity production of the system had yet to commence. The Republic of Korea Army already used the locally developed Kooryong series of 130 mm (36-round) multiple rocket launcher, as well as the US Lockheed Martin Missiles and Fire Control 227 mm (12-round) Multiple Launch Rocket System (MLRS).
The Hanwha-manufactured 70 mm (40-round) multiple rocket launcher system consists of a tracked or wheeled chassis fitted with a launcher that contains a total of 40 launch tubes (five rows each of eight rockets) in the ready-to-launch position.For some years, the company has been manufacturing a variety of 2.75 inch (70 mm) solid propellant unguided rockets for use in the air-to-ground role and these can be fired from a variety of fixed-wing aircraft and helicopters.
In addition to the unguided 70 mm rockets, a guided munition under development featuree GPS/laser/imaging IR guidance and a claimed CEP accuracy of 1 to 2 m.Details of these 2.75 inch (70 mm) rocket motors and associated warhead are given in the table. The K223 solid propellant rocket motors are typically used by high-performance aircraft, as well as helicopters and other low-speed aircraft, and have a substantially higher thrust and longer range than the MK40 rocket. They have wrap-around fins at the rear.The MK rocket motor is used for higher speed aircraft, while the MK40 is used by low-speed aircraft and helicopters.
