In 1951, MIT Lincoln Laboratory was established to develop an air defense system for the nation. The resulting system, the Semi-Automatic Ground Environment (SAGE), connected over 100 radars, 24 direction centers, and 3 combat centers. The system was revolutionary in its complexity and its approach to computing.

To learn more about the history of this project and the Laboratory, please visit the new history section of the Laboratory’s website, and enjoy interviews with key personnel on the SAGE project, an animation of how SAGE worked, and many more resources.
