Overview

• Satellite analysis by investigative outlets including Tochnyi identifies six concentric circular structures near Tschernjachowsk in Kaliningrad consistent with a Circularly Disposed Antenna Array.
• The installation’s outer ring is reported at roughly 1.6 kilometers in diameter, making it unusually large for this class of system.
• Construction began in 2023 and the latest imagery indicates the site is now close to finished, according to open-source researchers.
• CDAA systems are used for radio geolocation and signals intelligence, and analysts say this station could monitor military communications over long distances, with cited ranges up to about 7,400 kilometers.
• The location near Poland and the Suwałki Gap underscores the strategic implications for NATO, with reports noting Russia previously built dozens of similar arrays and separate claims that German services may operate comparable sites remain unconfirmed.
