[3][failed verification] The designer of the radars, RTI Mints, says that each Daryal receiver is 100 × 100 m and has 4,000 cross dipoles.

[5] The first Daryal type radar was an active electronically scanned array built at Olenegorsk in 1977.

New Daryal-U radars were planned for Balkhash-9 near Sary Shagan in Kazakhstan, Mishelevka near Irkutsk and Yeniseysk-15 near Krasnoyarsk in Siberia.

The Mukachevo one in Ukraine was never completed after the fall of the Soviet Union and the Skrunda facility was demolished by a newly independent Latvia, arranged by the US Department of Defence.

[6][10] The Yeniseysk (Krasnoyarsk) Daryal-U site caused concern in the West over compliance with the ABM Treaty during its construction in the 1980s.

Following negotiations, in September 1989 the Soviets admitted it was a violation of the treaty, construction ceased and the facility was eventually dismantled.
