LSPR to support the objective configuration for CH-53K, and the LSPR integration will continue into 2017-18. Fielding
of the ATW and LSPR configuration is
planned in FY2020."
In response to a Universal Urgent
Need Statement (UUNS) issued in 2014,
DoN LAIRCM ATW systems are also being deployed on the Marine Corps' MV22 aircraft. Captain Schuessler says the
MV-22 Integrated Test will be completed
this year with DoN LAIRCM A-kit retrofitting of 24 UUNS aircraft beginning in
May and production B-kits provided to
support installation throughout 1Q2017.
"DoN LAIRCM will be fielded with a
GLTA, and the Program Office will continue to evaluate CIRCM feasibility for a
GLTA replacement."

CIRCM/DAIRCM
Until the JATAS cancellation in 2014,
the expectation was that the Common IR
Countermeasures (CIRCM) system would
interface with both JATAS for the Navy
and with the Army's CMWS. Northrop
Grumman delivered the first CIRCM systems to the Army earlier this year under an Engineering and Manufacturing
Development (EMD) contract awarded in
2015. According to Carl Smith, Northrop
Grumman Vice President of Mission Solutions, Land & Avionics C4ISR Division,
the system is currently going through a
series of rigorous qualification tests to
prove system performance across the
full range of operational environments.
"In parallel with this, we're making sure

we have the infrastructure in place to
support follow-on production. The Army
is very committed to this program and
plans to field over 1,000 systems for
training and deployment on all helicopters and some fixed-wing aircraft."
The Army plans to reach a low-rate
initial production decision in the middle of fiscal 2018 and a full-rate production decision in fiscal 2020. Initial
operational test and evaluation will
be conducted in fiscal 2019. As for the
Navy, Smith points out that CIRCM was
designed around an open architecture
and, "we planned for CIRCM to have multiple, open interfaces so it could easily
be integrated with existing and future
missile warning systems. It does interface with existing Northrop Grumman
missile warners and we can rapidly integrate with any new missile warner the
Navy may field to replace JATAS."
Captain Schuessler, says "the Navy
requirement for a next-generation
MWS integrated with a Directed Infrared Countermeasure (DIRCM) for rotorcraft platforms still exists. The AN/
AAQ-24 DoN LAIRCM is the integrated
MWS/DIRCM solution for our large aircraft. The system is already fielded on
the CH-53E and P-8, and will soon field
on the KC-103J, MV-22 and the CH-53K.
DoN LAIRCM has performed well, but
there are trade-offs in the areas of size,
weight and power, even for our large
aircraft, and it exceeds the SWAP allocations on our smaller platforms (e.g., the
AH-1Z, UH-1Y and the MH-60R/S)."

Captain Schuessler explained that, in
2015, the PMA-272 office was conducting
market research to find a replacement
MWS to integrate with the Army-lead
Common IRCM (CIRCM) system when a
Joint Urgent Operational Need Statement (JUONS) was issued to account for
a new threat in a particular area of operations. "The schedule requirement associated with the JUONS did not afford
the traditional timelines required to develop, integrate and test a new system.
DoN LAIRCM was selected as the solution for integration into the large aircraft in response to the JUONS, but for
the smaller aircraft, the Program Office
vetted a system that has been developed
and funded as a technology maturation
tool for both JATAS and CIRCM. That
system, the Distributed Aperture IRCM
(DAIRCM) system, has been successfully
demonstrated on multiple platforms and
live-fire events." DAIRCM was approved
by OSD as the solution for small aircraft
in response to the JUONS.
Relative to CIRCM, Captain Schuessler
says the loss of JATAS and the priority
demanded by the JUONS has delayed the
Navy's planned participation in the program. "Post JUONS, the Navy will evaluate paths forward for the smaller/lighter
rotorcraft, as well as looking at CIRCM as
a potential SWaP reduction on the AN/
AAQ-24 system as well. The Navy continues to participate in the CIRCM technical and program reviews, and plans to
procure CIRCM test articles in FY17."
In the meantime, Captain Schuessler
says the AN/AAR-47 MWS will continue
to interface with the ALE-47 Countermeasure Dispensing System (CMDS), as it
is not capable of cueing CIRCM. The DoN
LAIRCM (AN/AAQ-24) currently employs a
Guardian Laser Tracker Assembly (GLTA)
as its DIRCM. "CIRCM will be evaluated as
a potential replacement of the GLTA to
reduce [aircraft] SWaP," she says.

RF THREAT WARNING
The Army and Navy are also introducing an upgraded RF warning system
for their helicopters. Most Army, Navy
and Marine Corps rotorcraft platforms
carry a variant of the Northrop Grumman AN/APR-39 radar warning receiver
(RWR). The Army had decided to piggyback and leverage the ongoing AN/APR-
