Summary

The Defense News reports that satellite imagery analysed by Finnish synthetic aperture radar company ICEYE shows a large over-the-horizon radar facility under construction near Gvardeysk, Kaliningrad. Images from late August 2026 reportedly show three antenna arrays, each more than 500 metres long, arranged in a star-like pattern and protected by a double fence. Construction appears to have begun around March 2023. Analysts assess the site may belong to Russia's 29B6 Container radar family, with possible detection ranges of 900-3,000 km and Russian claims of up to 10,000 simultaneous aerial targets for a fully operational system. The article also notes ICEYE findings of more than 20 new or expanding signals-intelligence and electronic-warfare sites in Kaliningrad, growth in GPS-spoofing antennas, and S-400 readiness observations near Baltiysk. The facility's operational status and final technical specifications remain unconfirmed.

Classification

Confidence: High

The primary subject is Russian construction of a long-range surveillance radar and associated SIGINT/EW expansion in Kaliningrad, an adversary military-intelligence capability affecting NATO and European air and maritime monitoring. It is not a defensive-preparation article about allied hardening or procurement.
