Ballistic Trajectory Extended Range Munition

The Ballistic Trajectory Extended Range Munition (BTERM) was a failed program to develop a precision guided rocket-assisted 127 mm (5-inch) artillery shell for the U.S. Navy. The program was originally named the Autonomous Naval Support Round (ANSR) and was developed by Alliant Techsystems.^[1]

The concept was similar to Raytheon's Extended Range Guided Munition with several simplifications and a larger rocket engine. The warhead was based upon that in the AGM-88 HARM anti-radiation missile, and was guided through GPS; however, unlike the ERGM it was intended to fly a strictly ballistic trajectory. Both programs were cancelled in 2008.^{[2] [1]}
