Northrop Grumman Systems Corp., Rolling Meadows,
Illinois, is being awarded $25,036,119 for cost-plus-fixed-fee task order 0512
against a previously issued basic ordering agreement (N00019-15-G-0026) for
Phase II of the Defensive Electronic Countermeasures Suite Upgrade for the
CH-53K. This task order includes
non-recurring engineering support to design, test and integrate the AN/AAQ-24
Large Aircraft Infrared Countermeasures Systems Processor Replacement with the
Advanced Threat Warning Missile Warning Sensors, the AN/APR-39D(V)2 Radar
Warning Receiver System, the AN/ALE-47(V) Countermeasures Dispensing System
with the Power PC Processor Upgrade and the Avionics Management System for use
on the CH-53K. Work will be performed in
Rolling Meadows, Illinois (97.5 percent); Stratford, Connecticut (1 percent);
West Palm Beach, Florida (1 percent); and Cedar Rapids, Iowa (0.5 percent), and
is expected to be completed in September 2021.
Fiscal 2017 research, development, test and evaluation (Navy) funds in
the amount of $25,036,119, will be obligated at time of award, none of which
will expire at the end of the fiscal year.
The Naval Air Systems Command, Patuxent River, Maryland, is the
contracting activity.

The LAIRCM (Large Aircraft IR CounterMeasures) has been
developed to protect US large aircraft from IR guided man-portable
surface-to-air missiles. It is a derivative of the proven AN/AAQ-24 Nemesis
Directional IR CounterMeasure (DIRCM) system. LAIRCM uses missile warning
system to detect and incoming missile, then the protection system directs a
pointer-tracker to the missile's seeker jamming it with a IR laser energy beam.
The system is a fully autonomous system not requiring
inputs coming from the aircraft crew. LAIRCM is being offered to the commercial
aviation segment as a protection mechanism against any potential terrorist
attack using man-portable, shoulder-launced surface-to-air missiles. Source: deagel.com
AN/APR-39D(V)2 Radar Warning Receiver/Electronic Warfare
Management System
Northrop Grumman
The Northrop Grumman APR-39D(V)2 Radar Warning Receiver
(RWR)/Electronic Warfare Management System (EWMS) is being designed to maximize
survivability by improving aircrew situational awareness via interactive
management of all onboard sensors and countermeasures. The APR-39D(V)2 will
merge the C(V)2 baseline with the Northrop Grumman Digital Receiver product
line, providing advanced RWR capability for today’s and tomorrow’s RF threat
environment. The system will feature the latest technology in a small,
lightweight configuration that protects a wide variety of fixed-, rotary- and
tilt-wing aircraft from today's most modern threats. Source: northropgrumman.com
AN/ALE-47(V) Countermeasures Dispensing System
In response to automated warnings of radar, infrared,
laser and other threats against aircraft, the AN/ALE-47 Countermeasures
Dispenser System (CMDS) both assists the crew in staying aware of the
threats, and managing the deployment of electronic warfare devices that operate
externally to the vehicle.[1] "Electronic",
in this context, covers enemy sensors across the electromagnetic spectrum. Electronic
defense includes, as well as receivers and computers that detect and analyze
threats, both countermeasures that are part of the aircraft, but also
expendables that are released from it.[2]
In other words, it both acts as an electronics
countermeasures suite controller and as an electronic warfare expendables
dispenser. It replaces the AN/ALE-39.
Alternatively, it can be controlled by other control systems, such as the AN/ALQ-213.
These expendables include radar-reflecting chaff, infrared countermeasures to confuse
heat-seeking missile guidance, and disposable radar transmitters. In addition
to active and passive countermeasures, expendables now include sensors for
both electronic support, electronic warfare, and other intelligence
functions such as chemical weapon detection using materials
MASINT. In addition to the truly expendable items usually released as
cartridges, a modern dispenser system will control towed decoys that lure
radar- and infrared-guided missiles that avoid the other countermeasures. Source:
