Fortress Crimea: Under the Russian radar dome – DFRLab
Like the S-400 air defense systems covered previously, most of these radar assets fall under the 3rd Radio Technical Regiment of the 4th Air and Air Defense Forces Army’s 31st Division, which covers the Azov and Black Sea region more broadly. Most Russian non-naval air and air-defense assets on the peninsula fall under the 31st Division.
Most of these sites have radars in different frequency ranges, allowing for a mixture of early detection and precision tracking of airborne threats. Lower frequency (greater wavelength) radars have greater range and generally perform better against stealth technologies but at the expense of accuracy. Conversely, higher frequency radars more accurately track targets, albeit in a more confined range. These enhanced detection and tracking capabilities become useful when integrated with existing air and air defense assets.
It is worth noting that this article does not cover the seemingly halted construction of a Voronezh early warning radar, which would replace the now-defunct Soviet-era Dnepr radar station at Sevastopol. If completed, the Voronezh would provide improved ability to detect and track ballistic missile launches southwest of the peninsula.
The radar site near Uyutne, largely unchanged since receiving a fresh batch of new and old radars in 2016, underwent an interesting change during the spring and summer of 2019 as a new radome appeared on the northern part of the compound, in place of a 36D6 search and acquisition radar that had previously occupied the same position. Radomes are protective sphere or semisphere-like structures that protect radars from the elements and visual identification and are constructed specially to avoid interfering with a radar’s waves. The site was located just west of the large town of Yevpatoriya on the northwestern part of the peninsula.
