In the event of World War III, even neutral Sweden was prepared for a fight. Here's What You Need to Remember: Taken all together, a single Bas 90 base complex would be spread of a large area, and have several kilometers of usable flight strips and taxiways in total, creating a larger target area that was also more discreetly camouflaged into the road system. Although Sweden does not share a border with Russia, the Scandinavian country is a mere 500 kilometers—or about 330 miles—from Kaliningrad, the Russian exclave on the Baltic Sea sandwiched between Poland and Lithuania. Kaliningrad, also Russia’s westernmost point, remains ice-free in winter and thanks to these two geographical features, the formerly German territory hosts the Russian Navy’s Baltic Fleet headquarters, as well as two air bases.
