asingly Lethal Variety of Threats

The AAR-47B(V)2 upgrade configuration of the system provided for improved missile and laser warning, as
well as an HFI capability. Terry Thames,
Business Development Manager for Orbital ATK - Defense Electronic Systems
Division, says "the -47 is basically a
sensor of sensors with UV for missile
warning and IR for laser warning, all in
the same sensor envelope. We're always
looking at introducing new technology
into the sensor housing, but it must fall
within the same footprint of the existing system."
Many of the Navy and Marine Corps'
existing missile warning systems, including the AAR-47 (particularly on
newer platforms), had been planned
for replacement with the new AN/AAR59 Joint and Allied Threat Awareness
System (JATAS), but that program was
cancelled in late 2014 altering those
plans. As described by Thames, after
the 47B(V)2 configuration was introduced, there were some sustainment
modifications to the system that in-

cluded a new variant of the computer
processor. The A(V)2 sensor configuration systems (primarily with the Air
Force) and B(V)2 configuration (primarily Navy) have both been upgraded with
the new processor. The new variants,
which comprise all new procurements of
the system, are known as the D(V)2 and
E(V)2 respectively. Says Thames, "The
configurations support both branches
and their platforms. As requirements
come forward, the Air Force is replacing some of its 'A's but it's not a huge
effort. The Navy, however, is replacing
a significant number of its B configuration systems."
Although Thames says that the AAR47 as a product was not affected by the
JATAS cancellation, it did impact the
company's overall production plans. "We
needed to tighten our belt and find a
better way to economically manufacture the system." To accomplish this,
the company transitioned AAR-47 production to a different manufacturing
facility in Northridge, CA - an existing
Orbital ATK production facility for other
high-end Navy weapon system programs
that had space available to take in the
-47 production.
CAPT Laura Schuessler, Program
Manager of the Navy's Advanced Tactical Aircraft Protection Systems Program
Office (PMA-272) at Naval Air Systems
Command, says replacement of the AAR47 with the latest AN/AAR-47 D(V)2 or
E(V)2 versions of the system will be
platform dependent based upon other
installed aircraft survivability equipment, and the aircraft's mission. "The
AAR-47 program recently overcame obsolescence issues in the microprocessor
and finalized testing of a new software
Operational Flight Program, which improves system performance and enables
a countermeasure smart dispense capability. Additionally, the AAR-47 program
redesigned and fielded an improved intermediate level depot test set that reduces component level returns to the
OEM and life cycle costs. The AAR-47

is positioned to remain in use for many
years to come."

DON LAIRCM
In addition to the AN/AAR-47, the
Navy also has the AN/AAQ-24(V)25 Department of the Navy Large Aircraft
Infrared Countermeasure (DoN LAIRCM)
system and its associated Advanced
Threat Warner (ATW) technology in
service on its larger platforms. Built by
Northrop Grumman (Rolling Meadows,
IL), the ATW provides missile warning
via a two-color IR sensor, as well as laser
warning, HFI and a situational awareness picture to the aircrew.
Marine Corps CH-53E "Super Stallion" helicopters were to integrate the
AN/AAQ-24B(V)25-configuration of the
system, with an initial operational capability (IOC) date originally planned
for 2014. Captain Schuessler says the
integration and the subsequent Integrated Testing (IT) and Follow-On Test
and Evaluation (FOT&E) required to
field the DoN LAIRCM ATW configuration on the CH-53E completed in FY2015,
but the assets intended for the CH-53E
(as well as the KC-130J) were redirected
to support higher-priority Joint Urgent
Operational Need Statement (JUONS)
efforts for USMC, USA, USAF and USSOCOM rotorcraft platforms. "The DoN
LAIRCM ATW configuration began fielding in 2016 in support of the JUONS,
and this will continue through FY2018.
Sufficient assets will be in place for
CH-53E and KC-130J to commence ATW
upgrades beginning in 4Q2017."
Operational testing of the nextgeneration CH-53K platform (with AN/
AAQ-24) is scheduled for FY2018 with
a CH-53K program IOC now planned for
2019. Captain Schuessler says the CH53K baseline configuration of the AAQ24 uses the current two-color IR sensors
and 2103 processor, but is planned to
begin integration of the DoN LAIRCM
System Processor Replacement (LSPR).
"Non-recurring Engineering began in
2016 to integrate ATW software into the

rotorcraft fleet.
The Orbital ATK
(Clearwater, FL),
UV-sensor-based
AN/AAR-47 is one
of the principle missile warning systems
deployed on Navy platforms.
Currently installed on over 3,000 domestic and foreign platforms/aircraft, in addition to providing aircrew warning, the
system's processor cues an onboard flare
dispenser (ALE-39, ALE-40, or ALE-47.) In
some aircraft, control and indication are
integrated into the Northrop Grumman
AN/APR-39 radar warning receiver controls and displays.
