   The Rayo (lightning) artillery rocket system was jointly developed by Famae of Chile and British Aerospace of United Kingdom. This project commenced in 1989.  It was considered the largest and most costly project of the Chilean arms industry. The first phase of the project concentrated on development of the rocket motor. The second phase involved development of the warheads. This project was intended to demonstrate the technological capabilities of the emerging arms industry in Chile and the ability to develop a new generation of weapons. The Rayo artillery rocket system was aimed both for the Chilean Army and export customers. The first pre-production system was complete in 1997. Since 2002 the Rayo project appears to be cancelled, although this has not been officially confirmed. The Chilean Army purchased Israeli-made LAR-160 rocket system, which has less range but is combat-proven and comes significantly cheaper.

   The Rayo launching vehicle carries two factory-sealed containers, each holding twelve 160-mm rockets. A standard rocket is 3.21 m long and weights 122.5 kg. A HE-FRAG warhead weights 49 kg. Cluster warhead, fitted with dual-purpose bomblets was also developed for this rocket system. It was designed primarily for anti-personnel mode, but capable of penetrating light armored vehicles. Maximum range of fire is up to 45 km. In flight rockets maintain a stabilizing spin. Training rockets were under development.

   The Rayo rocket system was fitted with a digital ballistic fire control system.

   The Rayo MLRS is based on the MAN SX2000 6x6 heavy utility truck. Another lightweight variant with a single 12-tube launcher, mounted on a trailer, was developed. The Rayo artillery system is modular and could be tailored to suit specific requirements.
