The Dunay-2 was a prototype built in Sary Shagan as part of the experimental missile defence system "A". It consisted of separate transmitter and receiver complexes separated by 1 kilometre (0.62 mi). The power of the radar was 100 kW and its range was 1,200 kilometres (750 mi).[4][5] The NATO codename was "Hen Roost".

Ruins of the Dunay-3M
The Dunay-3 (Russian: Дунай-3М, tr.Dunay-3M; NATO: Dog House) was an upgrade of the Dunay-2 located in Kubinka, Moscow and became operational in 1968. Following an extensive upgrade in 1978 it was renamed Dunay-3M as part of the upgraded A-35M ABM system. It consisted of separate receiver and transmitter buildings separated by 2.5 kilometres (1.6 mi).
The transmitter covered two sectors (roughly north and south) and its array was 200 metres (660 ft) long and 30 metres (98 ft) high. The power of each sector was about 3 MW. The receiver was a building 100 m×100 m containing 2 passive electronically scanned array radars as well as the command and control centre for the A-35 system. The range of the system was 2,500 kilometres (1,600 mi).
The radar was functional until it caught fire on 8 May 1988.
Dunay-3UPedit
This was a prototype of the Dunay-3U and was located in Sary Shagan test site.[3] It was given the NATO codename "Top Roost".
Dunay-3Uedit
The Dunay-3U (Russian: Дунай-3У, tr.Dunay-3U; NATO: Cat House) was built in 1978 as part of the upgraded A-35M anti-ballistic missile system. It is located in Chekhov and was structurally similar to the Dunay-3M – it has a separate receiver and transmitter separated by 2.7 kilometres (1.7 mi). There are two sectors. It was capable of identifying the launch of Pershing II missiles from West Germany.[6]
In 1995 A-35M was replaced by the A-135 anti-ballistic missile system which used the Don-2N radar. One sector was decommissioned in 1998 and is now ruined and the other is used for space surveillance of satellites in low Earth orbit. As a UHF radar it can identify smaller objects (15–40 cm) than the VHF radars such as the Daryal and Dnepr.[3]
The Dunay-3U was commissioned in May 1978 with a life of 12 years. Both sectors were extended until 2000 but one sector (62) was decommissioned in 1998. The other one (61) has been extended in 2001 and 2005 – the last extension was until December 2009,[3] but it may have been extended again. In 2012 the Russian Ministry of Defence issued a tender for the demolition of sector 62.[7]
Before 2003 the transmitter had 30 waveguides each excited by a 100 kW transmitter. Since 2003 the station has been operating at a reduced power of 500 kW rather than 1800 kW, with 12 transmitters (out of 24) rather than the previous maximum of 30. The radar is chirped.[3]
The radar's computer system is made up of 10 K340 computers.[3]
