New satellite images suggest military buildup in Russia’s strategic Baltic enclave

Kaliningrad — Russian territory that’s sandwiched between Poland and the Baltics but disconnected from the rest of Russia, known as an exclave — has been a focal point in tensions between Russia and the West.

Earlier this year, aerial images came to light that suggested the Russians had significantly modernized a nuclear weapons storage bunker in Kaliningrad. Now, satellite imagery and analysis from ImageSat International, a commercial satellite firm, appear to confirm that a major modernization is underway in at least four locations throughout the region.
