In 1952, SRI-244 began development of what would become the P-15 early warning radar. By 1955, the radar had passed state tests and was accepted into service with the anti-aircraft troops of the Soviet armed forces. [ 1 ] The P-15 was designed to detect low-flying aircraft and was associated with the S-125 “Neva” (NATO name SA-3 “Goa”) anti-aircraft system, although it was later replaced by the P-15M2 “Squat Eye” radar, which mounted a single radar antenna on a 20-30 meter mast to improve coverage.

In 1959, the modernized P-15M wake radar underwent the state testing program, replacing the outdated mercury-based electronics. In 1962, another modernization of the P-15 underwent testing as the P-15N, being developed and produced by the Ulyanovsk Mechanical Plant. [1] The P-15N introduced a more sensitive receiver, which improved detection range, and a new amplifier for the transmitter. Further improvements were made in 1970, when the P-15MN passed testing. The P-15MN included a coherent pulse Doppler filter (moving target indicator) to eliminate passive clutter (up to 50 dB), [1] the first radar of its type in the Soviet Union. [ 3 ] Finally, in 1974, modernization of the P-15 was so extensive that it resulted in a new designation, the P-19 “Danube”, also known as 1RL134. The P-19 is known in Oc
