The radar was later installed near the Kura Test Range in Kamchatka in the Russian Far East as a part of 5K17 (GRAU index) tracking and measuring system and was demolished in 2006.

[2] The radar was built as part of the S-225 anti-ballistic missile system (codename of the R&D work: Azov;[2] US name: ABM-X-3), a marginally mobile system designed to defend high status targets against attack by ballistic missiles.

Because of this it was decided that the second prototype should be installed in Kamchatka, near the Kura Test Range, to pick up missiles landing there after being launched elsewhere in the Soviet Union.

One missile, 5Ya27 (developer's name V-825), was designed by OKB Fakel for exoatmospheric intercepts (above the atmosphere).

The other, high-acceleration 5Ya26 (aka PRS-1) was designed by OKB Novator for endoatmospheric intercepts (within the atmosphere).
