Electronic Warfare: Costly Radar Warning Receiver Duplication Continues (Chapter Report, 11/29/93, GAO/NSIAD-94-4)

Despite recommendations from Congress that the military services build
common electronic warfare systems that can be shared, the Air Force and
the Navy have continued to acquire radar warning receivers for
fixed-wing aircraft that lack commonality.  This lack of progress stems
in part from the Defense Department's (DOD) reliance on a flawed
analysis justifying the perpetuation of separate radar warning receiving
programs.  The prospects for achieving commonality for future fixed-wing
fighter and attack aircraft are also unclear because DOD has no plans to
ensure use of a common system.  GAO believes that commonality is
feasible and that substantial savings can be realized.  The Army has
acquired a common radar warning receiver for its helicopters, and a
follow-on system for Army and Marine Corps special purpose aircraft and
helicopters is being jointly acquired, with savings estimated to be
equal to the system acquisition cost.
