Design and deployment
The Starshel rounds were developed and deployed in the early 1980s and were operationally deployed in the mid-80s. By the mid-1990s the rounds were issued to every artillery unit in the Bulgarian army as special ammunition. A full jamming kit consists of several rounds, covering a jamming range of 20 to 100 MHz (with 5 rounds) for the R-045 and from 1.5 to 120 MHz (with 8 rounds) for the R-046. The fins of the round are deployed in-flight. After contact with the ground, an automatic fuze fires the 1,5 meter-long antenna up, which is powered by a small lithium battery for at least an hour. The effective jamming range is at least 700 m. Usually 1 or 2 Starshel kits are used to completely jam enemy front-line communications on a tactical scale.
