AGM-137 TSSAM

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". Missile development began in 1986 but revelation of cost-overruns in 1991 prompted the Army to pull out of the project and an investigation of the procurement process by the General Accounting Office (GAO, now referred to as the Government Accountability Office). 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.
