RUS-2 (abbrevation of Radio Ulavlitel Samoljotov, Cyrillic: «РадиоУлавливатель Самолетов», i.e. radio- aircraft-catcher), second name “Redut” («Редут») was a radar developed by the former Soviet Union. It was developed between 1936 and 1940.

The radar used separate transmitting and receiving antennas, both of which rotated synchronously with the associated cabins on a chassis of the automobile GAZ-3A. The antennas were Yagi antennas of 7 elements. The display of the received pulses was made in the receiving cabin on an A-scope. Later versions (since 1942) used a larger cabin on a ZIZ-6 chassis, with only the antennas rotating. Older versions were then named “Redut-40”. In the air defense of Leningrad and Moscow 30 of these radars were used.
