The story
The Voronezh Scientific Research Institute of Communication (VNIIS) was founded in Voronezh in 1958, and Sozvezdie is headquartered in this city.
In 1963 Sozvezdie was the first in the world to create a fully-fledged mobile communications system.
The organization was founded on July 29, 2004 by decree of the Russian president. It has developed Russia's new multi-functional electronic warfare weapon system.
On July 16, 2014, the Obama administration imposed sanctions through the US Department of Treasury's Office of Foreign Assets Control (OFAC) by adding Concern Sozvezdie and other entities to the Specially Designated Nationals List (SDN) in retaliation for the ongoing Russo-Ukrainian War.
