ISI revealed a new Russian CDAA in Crimea peninsula. The array’s diameter reaches 190 meters, and is surrounded by 16 antennas.
A new KRUG CDAA found in Crimea
During the Cold War, the Soviet Union deployed dozens of large, circularly disposed antenna arrays (CDAAs) for radio direction-finding and signals intelligence (SIGINT/ELINT) collection. Two of them were installed in today Crimea territory. Those who are interested in the nature of the particular radar can read the publication in the CIA archives from the 1960s. According to the same CIA publications, this is an antenna array with a range of thousands nautical miles. Depending on the number of antennas in the array.
There are several types of antenna arrays. The new array ISI detected within Crimea includes 16 antennas. The array’s diameter reaches 190 meters. ISI assesses that the site was built in the last year, possibly starting from November 2017.
While there is not much documentation on the array of 16 antennas made in Russia, previously the USA has developed such array under the name AX-16 Pusher antenna arrays (a miniaturized version of the AN/FRD-10 ). Additional data can be found on apps.dtic.mil .
Here to stay
The new CDAA is located in Sevastopol Area. Construction of such an array by the Russians could indicate two trends – a sign of sovereignty over Crimea and a desire for continuous intelligence monitoring in the Black Sea. A state will not set up such an array of antennas in the territory it is about to return.
In the Black Sea context, such an array provides a radius of monitoring several thousand nautical miles and signals the desire of the Russians to gain full control of the Black Sea. It can be estimated that such an array of antennas provides the Russian Black Sea Fleet with coverage up to the Straits of Gibraltar. In this way, the Fleet can follow the events in the Mediterranean and Black.
There is no doubt that the establishment of the antenna system together with the thickening of the Russian air defense in the Crimea area marks the establishment of the Black Sea Fleet in Crimea.
