"Think Tank Flashback" is a new series where Think Tank Watch looks back at now-defunct think tanks. Starting off is a little-known US government think tank. Here is a description of this think tank from the National Archives:
The Weapon Systems Evaluation Group (WSEG) was a government think tank organization born in the early days of the newly-created National Military Establishment (NME) that later became the Department of Defense. The WSEG performed operational research on defense matters from 1948 to 1976. Very little is publicly known about the WSEG as its records were highly classified and difficult to declassify.
The National Declassification Center (NDC) has much more information about the think tank.
