AN/ALQ-149 Communications Jammer

The EA-6B has been operational since 1972. It has undergone a number of upgrade programs: Expanded Capability, Improved Capability (ICAP), and ICAP II. A subset of ICAP II was installed on operational aircraft in Desert Storm and included HARM capability and updated communications. A major set of upgrades, designated Advanced Capability (ADVCAP) was in FSD in FY93. These included onboard system upgrades and substantial changes to the aircraft itself. ADVCAP warfighting improvements included a new receiver processor system, the AN/ALQ-149 Communications Jammer, a new band 2/3 transmitter, and an upgrade to the universal exciter.
