AIRBORNE ELECTRONIC WARFARE SYSTEMS
ALR-66B(V) 3 AND ALR-66C(V) 3 ESM
BRIEFING: The ALR-66B(V) 3 ESM is installed in the P-3C as its
primary electronic intelligence and targeting system to detect and
classify radar emitters for tactical or intelligence purposes. It features improved sensitivity over the ALR-66A(V) 3, and replaced
the older ALQ- 78 ESM system in many P-3Cs. The ALR-66C(V) 3
— installed in the P-3C Anti-Surface Improvement Program (AIP)
version — is interfaced with an AS- 105 spinning direction-finding
antenna. Both versions send intercepted signals to the EP-2060
pulse analyzer that analyzes parameters of an intercepted signal.

ALR- 95(V) SPECIAL EMITTER
IDENTIFICATION (SEI) PULSE
BRIEFING: The ALR- 95(V) 1 provides P- 3 AIP aircraft with
integrated conventional pulse processing and SEI capability.
The ALR- 95(V) 1 signal processor combines a video pulse
processor and an SEI capability into a single component. The
SEI capability provides SEI functionality, pulse train analysis
and RF distribution via the ALR-66C(V) 3 system.
The ALR- 95(V) 2 upgrade, completed in 2008, replaced most
ALR- 66 components and improved processing capability. The
latest ALR- 95 upgrade, which began in 2008, will replace the
analog TN613 tuner with a digital TN-500 tuner and add AIS
CONTRACTORS:.........Exelis Corp., Lockheed Martin Mission
Systems & Training
BRIEFING: The ALQ-210 ESM system installed on the MH-60R
helicopter is designed to detect, classify and locate radar emitters on land, surface vessels, submarines and aircraft.
CONTRACTOR: ...........Lockheed Martin Corp.
ASQ-239 EW SYSTEM
BRIEFING: The ASQ-239 is designed to provide the F- 35 aircraft with warning and electronic support measures to increase
situational awareness and survivability versus radar-guided
weapons. The ASQ-239 is likely to feature some electronic jamming capability through the AESA radar.
CON TRACTOR: ...........BAE Systems
ALQ-240(V) 1 ESM SYSTEM
BRIEFING: The ALQ-240 (V) 1 is the ESM system installed on
the P-8A Poseidon maritime patrol aircraft. It features adaptive
tuning, precise direction finding and geo-location capabilities.
IOC was achieved in 2013.
CONTRACTOR: ...........Northrop Grumman Electronic Systems
ZLQ- 1 ESM SYSTEM
BRIEFING: The ZLQ- 1 is the ESM system designed for the MQ-
4C Triton UAV. The digital system features specific emitter identification.
CONTRACTOR: ...........Sierra Nevada Corp.
AIRBORNE SONAR SYSTEMS
AQS- 24 MINEHUNTING SONAR
BRIEFING: The AQS-24A is an active sonar winched and towed
through the water by an MH-53E mine-countermeasures helicopter. It is designed to detect mines for further investigation by
mine warfare forces. The AQS-24A uses sonar simultaneously
with a laser line scanner to provide precision optical identification of underwater mines. The sonar also has been ordered by
Japan for use on its minesweeping helicopters. The AQS-24A
also is the sensor for the Mine Hunting Unmanned Surface
Vehicle. The AQS-24B version in development features
improved image resolution and increased speed of real-time
CONTRACTOR: ...........Northrop Grumman (Westinghouse)
AQS- 22 AIRBORNE LOW-FREQUENCY
BRIEFING: The AQS- 22 ALFS is the primary anti-submarine warfare sensor for the MH-60R multimission helicopter. The ASQ- 22
is dipped into the water by a reel on the helicopter and used to
detect, track and localize a submarine. It also can be used for passive acoustic intercept, underwater communications with a submarine and collecting bathythermal information of the ocean.
Low-rate initial production began in 2002 and full-rate production
in 2006. The ALFS was first deployed operationally in 2009.

AQS-20A MINEHUNTING SONAR
BRIEFING: The AQS-20A is a variable-depth, underwater
mine-detection sonar designed to give a strike group an organic
capability to detect, classify and localize bottom, close-tethered
and volume mines. The AQS-20A also is fitted with an electro-optic sensor to identify underwater objects. The sonar is
deployed while the helicopter is in a hover and then towed
undersea to scan the water in front and to the sides of the aircraft, as well as the sea bottom for anti-shipping mines. The
sonar and electro-optical sensor provide high-resolution images
of mines and mine-like objects as well as high-precision location information.
The AQS-20A is a component of the Remote Multimission
Vehicle and the Airborne Mine-Neutralization System in the
mine warfare mission package of the LCS. The AQS-20A entered
low-rate initial production in 2005.
