The AN/ALQ-161A system is an integrated RF electronic countermeasures system designed specifically for the B-1B bomber aircraft. The system is designed to detect and counter all modes of radar based weapon systems and also provides a tail warning function to detect and counter incoming missiles from the aft sector.
The system provides 360-degree simultaneous receive and jamming coverage against a large number of concurrent threats. The ECM system sorts threats by priority and reacts against them automatically while allowing for “man-in-the-loop” intervention.
The AN/ALQ-161A is a totally integrated radio frequency countermeasures system that is made up of over 108 Line-Replaceable Units, weighing over 5,000 lbs, consuming about 120 kW of power. The AN/ALQ-161A, which was initially delivered in the 1980’s, has been sustained through a series of OFP block cycle upgrades and hardware upgrades to incorporate modifications necessary to detect and counter the ever changing threat.
Exelis is developing new capability for the AN/ALQ-161A to meet the future needs of the B-1B and its crew through its retirement in 2048.
