electronic countermeasures (ECM) jamming pods for transmitting and a single fixed pod on its tail for receiving The ALQ-99 is an airborne integrated
jamming system designed and manufactured by
EDO Corporation. Receiver equipment and antennas are mounted in a fin-tip pod while jamming transmitters and exciter equipment are located in under-wing pods. The system is capable of intercepting, automatically processing and jamming received
radio frequency signals. The system receivers can also detect, identify and
direction find those signals, providing
signals intelligence (SIGINT) either automatically or manually. in the foreground carrying a fixed tail pod for receiving and a fixed transmitting pod on underside. Note that while the EA-6B carries removable transmitter pods, the EF-111 has the transmitter built into the underside of the aircraft. The AN/ALQ-99 was mounted on the
US Navy and
US Marine Corps EA-6B Prowler aircraft and the Navy's
EA-18G Growler aircraft. It was mounted on
US Air Force EF-111A Raven aircraft before these aircraft were retired from service by May 1998.
EA-6B Prowlers were retired from active service following deployment in 2015. The AN/ALQ-99 has a maximum power output of 10.8
kW in its older versions and of 6.8 kW in its newer versions. It uses a
ram air turbine to supply its own power. The AN/ALQ-99 is capable of jamming frequencies from to . Jamming frequency ranges are set forth in 10 bands: •
