The United States Department of Energy National Laboratories and Technology Centers are a system of facilities and laboratories overseen by the United States Department of Energy (DOE) for the purpose of advancing science and technology to fulfill the DOE mission. Sixteen of the seventeen DOE national laboratories are federally funded research and development centers administered, managed, operated and staffed by private-sector organizations under management and operating (M&O) contract with DOE.
The system of centralized national laboratories grew out of the massive scientific endeavors of World War II, in which new technologies such as radar, the computer, the proximity fuze, and the atomic bomb proved decisive for the Allied victory. Though the United States government had begun seriously investing in scientific research for national security since World War I, it was only in late 1930s and 1940s that monumental amounts of resources were committed or coordinated to wartime scientific problems, under the auspices first of the National Defense Research Committee, and later the Office of Scientific Research and Development, organized and administered by the MIT engineer Vannevar Bush.
During the second world war, centralized sites such as the Radiation Laboratory at MIT and Ernest O. Lawrence's laboratory at the University of California, Berkeley allowed for a large number of expert scientists to collaborate towards defined goals as never before, and with virtually unlimited government resources at their disposal.
