The Voronezh-M type early-warning radar in Mishelevka was reported to begin combat duty service (UPDATE: It's "experimental combat duty") at 10:15 local time (05:15 MSK, 01:15 UTC) on May 23, 2012. The radar has been undergoing trial since March 2012.
The radar is also known as Voronezh-VP (77Ya6-VP), where VP stands for "high-potential." The antenna area of the Mishelevka radar is larger than that of its Voronezh-M predecessor deployed in Lekhtusi (which began combat duty in February 2011). One more antenna face will be added to the radar in the future extending its coverage to 240 degrees.
