Russia appears to be building permanent structures to house its SS-26 Iskander missile systems in the Kaliningrad enclave bordering Poland and Lithuania. These reports come from arms control experts who have used satellite imagery to pinpoint the location of the Iskanders and are now beginning to see the construction of permanent structures to shelter these missiles. Iskanders, with the NATO designation SS-26, are short range ballistic missiles with a range of at least 500 km and the potential to carry a nuclear warhead. Although the Russian Defense Ministry cites the missiles’ presence in the region as part of routine drills, the permanence of the base structures and close relative proximity to Western Europe adds to growing NATO-Russian tensions.
