Northrup AGM-137 Tri-Service Standoff Attack Missile

The Northrop AGM-137 TSSAM (Tri-Service Standoff Attack Missile) was a standoff cruise missile developed for the three branches of the United States Armed Forces, hence "tri-service". The TSSAM program was eventually cancelled in December 1994 pursuant to a GAO recommendation and the loss of support of the United States Army after going as far as several test launches.
