The AN/ALQ-99 has been used during the Vietnam War (1972–1973), Operation El Dorado Canyon (1986 American raid in Libya), 1991 Gulf War, Operation Northern Watch (1992–2003), Operation Southern Watch (1997–2003), 1999 Balkans War, 2003 Second Gulf War, and 2011 Operation Odyssey Dawn. The poor reliability of the ALQ-99 and frequent failures of the Built-In Test (BIT) have caused crew to fly missions with undetected faults; the ALQ-99 also interferes with the aircraft's AESA radar, reduces the top speed of the aircraft and imposes a high workload on the two man crew when employed in the EA-18G Growler.
