The United States Air Force is issuing a sole source contract to Smart Shooter Inc. for the proprietary SMASH Fire Control System. The requirement includes specific SMASH X4 and 2000LE units for the M4 rifle, a SMASH CAST system, a set of spare parts and test equipment, and associated shipping. All items must be delivered to Spangdahlem Air Base, Germany. The justification is based on the unique predictive tracking and targeting capability of the system, which is deemed essential and not available from any other known provider.
