P-14
The P-14 "Lena" was a long-range radar device for air reconnaissance in the Soviet Union and its allies. The NATO code name for this radar was "Tall King", to which the suffix "A" was later added to distinguish this radar from its successor, the Oborona ("Tall King B"). The P-14 was equipped with an additional secondary radar device of the type NRS-14 with the Kremnij-2 method.
With the dimensions of 33 m × 22 m, the parabolic antenna of the P-14 assumed a special position for the VHF range . The technical data of the radar station corresponded roughly to those of the P-12 . However, the transmitter was more powerful (pulse power = 700 kW). The maximum displayed distance was 600 kilometers, while the distance resolution deteriorated mainly due to the screen resolution and the extension of the broadcast time.
A P-14 had two main antennas. One of them was installed as a stationary working antenna and one was loaded on 36 Ural-375D vehicles ready for installation. The installation time for an antenna was about 50 hours.
