present for the ALQ-122, with no other
significant activity currently underway.
Other EW systems aboard the B-52 include the Northrop Grumman AN/ALT32 communication jammer; Northrop
Grumman AN/ALQ-153 tail warning system and the AN/ALE-20 flare and AN/
ALE-24 chaff dispensers.

THE COST OF INTEGRATION
As is probably clear at this point,
all of the different EW systems on the
B-52 currently largely operate completely independently of each other.
Northrop Grumman’s Janine Nyre observes, “Though the upgrade solutions
that we’re currently putting into all the
different EW elements on the B-52 are
basically plumbed to be able to communicate with each other, the funding
provided for these upgrades is specific
to individual system improvement requirements. So, if a requirement is seen
for a greater level of fusion between the
systems, that would probably need to be
funded as a separate requirement.”
ITT Exelis’ Carlson agrees. “For example, the -155 and -172 operate totally

independently right now. They cover
different frequency ranges and have
their own threat lists, but at the end
of the day, both systems are basically
designed for both the ground radar and
airborne interceptor role. We’ve talked
to the Air Force about whether it makes
sense to combine the systems, but as is
often the case with older platforms, the
cost to change the A-kit is just prohibitive, and it’s simply more cost effective
to keep the separate systems going.”

B-1B LANCER
The B-1B “Lancer” long-range bomber
can carry the largest payload of both
guided and unguided weapons of any
platform in the Air Force inventory. The
original B-1A version of the aircraft was

developed in the 1970s, but the muchimproved B-1B variant, incorporating an
order of magnitude improvement in radar
cross section (RCS) was launched in 1981.
The first production B-1B was delivered
to the Air Force in 1985 and the final aircraft in 1988. Projected to be operational
into 2048, there are currently 66 B-1B
aircraft in the Air Force inventory.
The B-1B’s onboard self-protection
equipment includes the AN/ALQ-161 integrated RF electronic countermeasures
system, the ALE-49 chaff and flare dispenser, and the Raytheon AN-ALE-50
towed decoy system. The AN/ALQ-161
system was designed specifically for
the B-1B by Eaton-AIL (now Exelis) and
is composed of over 108 LRUs. The system provides 360-degree simultaneous
receive and jamming coverage, sorting
and reacting to threats automatically
while also allowing for “man-in-theloop” intervention. The system also includes a tail-warning function.
The AN/ALQ-161A is the current version of the system, which has incorporated a number of major upgrades over
the last few years. For example, Exelis is

Join IMS2013 for what is sure to be an exciting and fervent Plenary talk led by
Dr. Patrick Ennis, Global Head of Technology, Intellectual Ventures.
Invention Capital: Why the World Needs More of it

Monday, 3 June 2013

“It is an exciting time to be a technologist. Every day, breakthroughs in research laboratories offer the promise of
products and solutions to meet a range of global challenges and opportunities. However, it is very difficult to successfully
commercialize technology; and unfortunately most efforts fail. We need to improve the success rate, otherwise billions of
dollars of R&D funding will be wasted, and innovation-driven economies will stall. Invention Capital is a missing link in the
value-creation chain.”
Dr. Patrick Ennis will talk about how researchers from a variety of
scientific and technical fields can optimize the value- creation chain.
He will be sharing new models such as Open Innovation and Invention
Capital that are necessary to successfully commercialize technology,
in today’s challenging environment where the speed of technology

development and adoption has so accelerated that even leading
technology companies find it hard to just keep up. This is an opportunity
for leading researchers to understand the latest trends in managing
valuable IP and bringing it closer to commercialization.
