Recommended for development by the bipartisan Presidential Commission on Strategic Forces, Midgetman is a new, small, highly mobile, single-warhead intercontinental ballistic missile. While the development and eventual deployment of Midgetman is expected to strengthen the land-based segment of the U.S. nuclear defense triad, it is also expected to influence or alter arms control negotiations. The single-warhead Midgetman would be fully effective only if limitations were set on the total number of warheads.
