The Satellite Launch Vehicle ( SLV , also SLV-3 ) was the first launcher that India developed itself. After ISRO was founded in 1969, it began to develop its own carrier system, which it completed in 1979. The rocket could bring a payload of 40 kg into orbit , with a takeoff weight of 17.8 t that was little compared to rockets of similar size. This was mainly due to the high empty mass of the steps of over 20%. The beam was 24 m high and only 1 m wide.

All launches took place from the Indian launch base Satish Dhawan Space Center on Sriharikota on the Indian east coast. The SLV 3 was a pure solid rocket . As is usual with solid-propelled launchers, the SLV also requires 3 free-flight phases, the first after the burnout of the second stage up to a height of 88 km and a second after burnout of the third stage, up to reaching the perigee . In 1989 an attempt was made to build a military medium-range missile from the first stage of the SLV 3. This is the only case in the history of space travel where a civil missile has been used for military purposes. Usually this happens the other way around.
