'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.
