a stand-alone system like ISR's AVR-2B
within the much smaller space available
within the combined solution. Today, the
AN/AAR-47 and the AN/AAR-59 are still
the only systems out there that integrate
laser warning, missile warning, as well as
HFI in this size and weight."
For the Navy's larger aircraft platforms,
the Advanced Threat Warner (ATW) being
developed by Northrop Grumman Land and
Self Protection Systems Division (Rolling
Meadows, IL) for the DoN Large Aircraft
IR Countermeasures (DoN-LAIRCM) system

also includes a laser warning capability
together with two-color IR missile warning and HFI.
Although the US Army has historically provided laser warning to its fleet
of rotorcraft and small fixed-wing aircraft
through the dedicated AN/AVR2B system,
it is now also looking at integrating the
capability into the AN/AAR-57 Common
Missile Warning System (CMWS). Built by
BAE Systems, the CMWS is currently incorporating a new HFI capability as a QRC
upgrade to the system, which together

service with other international users.
In October, the company was awarded
a five-year, $208.5 million contract by
the Army for continued procurement of
the AN/AVR-2B(V), an improved-performance version of the system which is
also smaller, lighter and uses less power
than previous versions.
Meanwhile, the US Navy and Marine
Corps have integrated a laser warning
capability into the AN/AAR-47(V)2 IR missile warning system currently in widespread use on both their rotorcraft and
fixed-wing aircraft. The AN/AAR-47 is
built by ATK (Woodland Hills, CA), but its
laser warning sensor is provided by BAE
Systems (Nashua, NH). The latest variant
of the system, the AAR-47B(V)2, includes
improved detection performance, clutter
detection, hostile fire indication (HFI)
capability, as well as laser warning. For
the AAR-47B(V)2, laser threat warning
includes threat-class identification and
mid-to-high-resolution angle of arrival
(AOA) information within milliseconds of
illumination. Up to seven simultaneous
threats can be processed and reported by
each sensor. According to BAE, the total
weight added to each AAR-47 sensor to
provide the laser warning function is less
than 5 ounces and requires less than 3W
of additional power. Navy and Marine
aircraft with the capability include the
AH-1W/Z, UH-1N/Y, CH-53D/E, HH/SH/
MH-60, P-3, C- 130, CH-46 and V-22.
Through the Navy's acquisition program, a number of Air Force platforms,
including the C-5, C-141, C-17, MH-53J,
HH-60G, C-130E/H/J, and HC-130N/P, as
well as a number of foreign military aircraft, have been equipped with the AN/
AAR-47A(V)2 variant of the system, which
also includes a laser warning capability.
Looking ahead, the Navy's next-generation airborne IR-missile-threat warning
systems also incorporate laser warning,
including the new AN/AAR-59 Joint and
Allied Threat Awareness System (JATAS)
being developed by ATK and teammate
BAE Systems. Although the approach to
integrating laser warning into the AAR-59
is similar to that taken with the AAR47 upgrade, the laser warning sensor in
this case is provided by ISR Systems. As
noted by ATK's Bill Kasting, "One of the
biggest challenges JATAS had to deal with
was providing all of the capabilities of
