The Voronezh-M early warning radar in Lekhtusi, near St.-Petersburg finally began combat duty on February 11, 2012. This is the latest in the series of announcements about the radar's beginning its operations - initial tests began in December 2005, experimental combat service - in December 2006. The radar was accepted for service in December 2009.

The radar in Lekhtusi is the first Voronezh-M radar, so its long way to the full operational status is not surprising. A radar of this class is being built in Mishelevka (it appears that two radars are built there). Russia is also building Voronezh-DM radars - two in Armavir, one in Kaninigrad - and planning to build one in Barnaul. New radars will also be built in Olenegorsk and Pechora.
