This officially transitioned the program away from IEWCS
Prophet Air requirements call for COMINT coverage from 20 MHz to 2 GHz -- as well as the ability to detect and locate the sources of low-probability-of-intercept signals -- over a 120x50-km area (as compared to 40x40-km coverage area required under the now-defunct IEWCS
However, since the Army had already changed its force structure to reflect the entrance of the now-canceled IEWCS
system, the program needed to show results quickly, according to Prophet Program Manager LTC Darrell Davis, US Army.
Following the tests, the Army decided that its IEWCS
operational requirements, dating back to 1990 for the GBCS equipment and 1992 for the AQF, should reflect new battlefield technologies and operational concepts.
Conceived in the late 1980s, IEWCS
was intended to be a common set of vehicle-mounted SIGINT and EW equipment, networked for intelligence gathering, precision targeting and coordinated jamming.
Originally, the MEWSS was to receive the jammer portion of TACJAM-A, similar to the IEWCS
In all, seven IEWCS
platforms - three Ground Based Common Sensor (GBCS)-Heavy vehicles, two GBCS-Lights and two Advanced Quickfix (AQF) helicopters - supported the Army's 1st Brigade, 4th Infantry Div.
In a triad of incarnations - the HMMWV-based Ground Based Common Sensor (GBCS)-Light, the Bradley Fighting Vehicle-derived GBCS-Heavy and the Advanced Quickfix (AQF) EH-60 helicopter - the IEWCS
is intended to replace the existing fleet of Army battlefield EW assets and will more or less embody Army division-level EW for well into the next century.
For a complete overview of the IEWCS
program, see "Don't Slam It, Jam It
program is designed to provide a common suite of direction-finding and jamming equipment for US Army light and heavy ground combatants, as well as an airborne package carried aboard an EH-60 helicopter.
The production competition will call for the performance of three tasks: integration of government-furnished and contractor-provided IEWCS
subsystems into both airborne and ground-based platforms; production of the TACJAM-A Electronic Support sensor subsystem; and production of the CHALS-X Communications Precision Location subsystem.
