In 1992, the US military and intelligence community actively recruited former Soviet military research facilities and weapons institutes, bringing hundreds of Soviet scientists onto the Pentagon payroll. The Soviet Scientists Immigration Act of 1992 (SSIA) facilitated this by providing 750 visas to eligible scientists and engineers from the former Soviet Union. The program expired in 1996, but legislation later extended eligibility until September 30, 2006, and increased the visa cap to 950.
Scientists who entered through other channels, such as exchange programs, temporary work visas, or refugee and family routes, also benefited, as the Act signaled an official preference for former Soviet scientists, easing their integration into US research efforts.
One notable example is Roald Sagdeev, a Soviet plasma physicist who married Susan Eisenhower, granddaughter of US President Dwight D. Eisenhower. Soviet aerospace engineers also assisted the US Air Force at Wright-Patterson Base. In the 1960s, a radar specialist at Lockheed’s Skunk Works recognized that Ufimtsev’s equations, translated from Russian, allowed precise calculations of radar wave reflections off flat panels. Lockheed used this Soviet mathematics to develop the F-117 Nighthawk stealth aircraft and the B-2 bomber. Following the Soviet collapse, Ufimtsev moved to the US, where his aerospace engineering concepts were integrated into US military research.
