The summer of 1991 marked the first time in recent history that Russia offered to escort ships of other countries across the Northern Sea Route (NSR). For moving cargo between the North Pacific region and Northern European ports, the NSR, along Russia's northern coastline, is between 35 and 60% shorter than the traditionally used routes through the Suez and Panama Canals. In addition to its shorter distance, there already exists an extensive ports and shipping infrastructure, a current cargo base, and the potential for developing new markets in Russia and other northern areas. These incentives are attracting considerable attention from the international shipping community, including that portion servicing Alaskan and northwestern U.S. ports. This report is a general compilation of the historical usage, recent trade developments, the current regulatory climate, the physical environment, the ports and navigational infrastructure, cost factors, and practical considerations that may shape future U.S. interests in the route.
