AN/ALQ-136

The AN/ALQ-136 CMS is an airborne, automatic, electronic radar jammer designed to defeat/degrade the tracking capability of hostile threat pulse radar. When threat signals are identified and verified, jamming automatically begins and continues until the threat radar signal is no longer detected. The CMS then ceases jamming but continues to receive and analyze radar signals. The AN/ALQ-136 CMS is programmed to respond to the pulse radar signals of the most critical threat weapon systems anticipated to be encountered in the hostile environment.

The AN/ALQ-136(V)1 CMS, used on on the AH-1F attack helicopter, consists of one receiver/transmitter (RT) assembly and two identical antennas. The operator control unit, designed to operate both the AN/ALQ-136(V)1 CMS and the AN/ALQ-144(V)3 or AN/ALQ-144A(V)3 Infrared (IR) Jammer, is provided as part of the AN/ALQ-144(V)3 or AN/ALQ-144A(V)3 IR Jammer. A plenum assembly (NSN 5865-01-195-0857), used to assist in the air cooling system on the AH-1F helicopter, is connected to the rear of the RT. The total system weight is 47.4 pounds.

The AN/ALQ-136(V)2 CMS is designed for the Special Electronics Mission Aircraft (SEMA) and the Special Operations Aircraft (SOA) -- RC-12, MH-47E, MH-60K, EH-60A. This CMS is programmed to respond to the pulse radar signals of the most critical threat weapon system anticipated to be encountered by SEMA and SOA in a hostile environment. It can operate against multiple threat weapons systems simultaneously. It has programmable modules, covers a broader frequency range than the (V)1 CMS and has built-in preplanned product improvement capabilities. The AN/ALQ-136(V)2 CMS consists of three types of line replaceable units (LRUs). These LRUs include one receiver/transmitter (RT) assembly, one control indicator assembly and four antennas. The RT assembly utilizes state-of-the-art gate array and gallium arsenide lightweight circuit boards. The total system weight is 72 pounds.

The AN/ALQ-136(V)5 CMS, used on the AH-64A/D, consists of one receiver/transmitter assembly and two different antennas. The operator control unit, designed to operate both the AN/ALQ-136(V)5 CMS and the AN/ALQ-144(V)3 or AN/ALQ-144A(V)3 Infrared (IR) jammer, is provided as part of the AN/ALQ-144(V)3 or AN/ALQ-144A(V)1 IR jammer. The total system weight is 47.4 pounds.
