“Compact, efficient, lightweight, and long-lasting energy technologies are emerging as a force multiplier in military affairs. Innovative power sources that can outperform the energy density of current batteries and fuel cells promise major weight and volume reductions. Advances in nanotechnologies are playing a crucial role in the development of new energy sources, generators, and harvesters. Many countries, including China, Iran, Japan, Russia, South Korea, and Taiwan, are researching these technologies. DIA judges with moderate confidence that while the United States can maintain its technological superiority in nonconventional energy sources for the next 5 to 10 years, technologies with strong commercial…

Background The collision between the USS Baton Rouge and a Russian Sierra Class submarine K-276 Crab (later named the B-276 Kostroma) occurred on February 11, 1992, in the Barents Sea, near the Russian naval base of Murmansk. The USS Baton Rouge was a Los Angeles-class nuclear-powered attack submarine of the United States Navy, while the Russian vessel was a Sierra I-class nuclear-powered submarine. The incident happened during a period of increased tension following the dissolution of the Soviet Union in late 1991. Both vessels suffered minor damages but there were no casualties on either side. The United States claimed that…
