The Ripsaw is a series of developmental unmanned ground combat vehicles designed by Howe & Howe Technologies (now part of Textron Systems) for evaluation by the United States Army. The Howe brothers started the Ripsaw as a small family project in 2000. They introduced it at a Dallas vehicle show in 2001, where it caught the interest of the U.S. Army. Later that year the U.S. military ordered a prototype MS-1 to be made and shipped to Iraq.
