Voronezh radars are the current generation of Russian early-warning radar, providing long distance monitoring of airspace against ballistic missile attack and aircraft monitoring. The first radar, in Lekhtusi near St Petersburg, became operational in 2009. There is a plan to replace older radars with the Voronezh by 2020.

The Daryal-type radar is a Soviet bistatic early-warning radar. It consists of two separate large active phased-array antennas separated by around 500 metres (1,640 ft) to 1.5 kilometres (4,921 ft). The transmitter array is 30 m × 40 m and the receiver is 80 m × 80 m in size. The system is a VHF system operating at a wavelength of 1.5 to 2 meters. Its initial transmit capacity was 50 MW with a target capacity of 350 MW.
