Dunay-3

The Dunay-3 (NATO designation: "Dog House") was an early warning radar operating in the UHF band (388–429 MHz) with a peak power of 3 MW and an instrumented range of 2,500 km. Located at Kubinka, 60 km west of Moscow, it featured separate transmitter and receiver buildings 2.5 kilometers apart. The transmitter used a 200-meter-long, 30-meter-high phased-array antenna covering two sectors, while the 100 × 100 m receiver building housed two passive electronically steered radar systems and the command and control center for the A-35 anti-ballistic missile (ABM) system. Commissioned experimentally in 1968 as an advancement of the Dunay-2, it was modernized in 1978 and adopted as the Dunay-3M for the A-35M ABM system until its receiver antenna was destroyed by fire on May 8, 1988.
