197 named after V.I.Lenin, the predecessor of the current Nizhniy Novgorod Research Institute of Radio Engineering (NNIIRT).

[2] The P-70 had a production run of 11[3] radar units which were deployed to many different regions within the Soviet Union including Estonia, Kotlas, Lithuania and Rybachy Peninsula in the north-west, Kerch, the North-East Bank and Azerbaijan in the south, Mongolia and Russian Island in the east and Anadyr in the north-east.

[1] The radar used a single large antenna accomplishing both transmission and reception with a surface area of 850 m2 and with dimensions of 48 by 25 meters.

[3] The use of these techniques gave the P-70 excellent resolution (by a factor of 10 compared with the P-14[1]) at long range, as well providing protection against active and passive interference.

The P-70 also used a fully coherent transmitter and an MTI system capable of compensating for wind and other forms of passive interference such as chaff.
