we’re going a step further by adding
threat geolocation capability to the
ALQ-172.”
Colonel Kelly reports that the ALQ172(V)2 is continuing to receive regular
software block cycle updates with new
versions expected in the second quarter
of FY2014 and again in fourth quarter of
FY2015. “In terms of hardware,” he says
“really all we have going on right now
is again a number of form-fit-function
replacements of SRUs within the system
primarily to resolve obsolescence is-

sues.” Colonel Kelly adds that they also
have some study activities investigating
other possible future LRU-level, formfit-function obsolescence replacement,
but at present, none of these are funded
activities. “They’ve been examined, but
have not been brought forward as programs of record.”
Meanwhile, Carlson says the company is nevertheless well down the path
of designing the next version of the 172,
which will involve replacing some of the
system’s existing LRUs with a “technol-

synchronized instrumentation

ogy-refreshed” version. “It’s a direct
replacement for the current ALQ-172,
but with improved maintainability and
reliability, and with hooks for the next
generation of threats.”
Jared Belinsky, Exelis’ B-52 Program
Manager, says although the program,
known as the Maintenance and Reliability Systems (MARS), is partially funded
by the Air Force, it also includes technology from some of the company’s other
jamming systems, like the AN/ALQ-211
and AN/ALQ-214, as well as ongoing research. “A lot of what is going into the
MARS design is based on the technology
we’ve borrowed from other programs or
funded with our own internal R&D.”

OTHER EW CAPABILITIES
Both the importance of the mission and the complexity of the threat
can be seen in the number of other
EW systems carried by the B-52. These
include the AN/ALR-46 digital radar
warning receiver (RWR) covering radar emissions in the 2- to 18-GHz band
and simultaneously identifying up to
16 radar signals. Originally produced
by Litton, the ALR-46 was replaced
on a number of other Air Force platforms with the Litton-manufactured
AN/ALR-69(V) system in the 1970s
and 1980s. However, the B-52 was not
included among these. According to
Colonel Kelly, they are continuing to
conduct routine product support for
the ALR-46 system, with no significant
upgrade plans at present.
The B-52 is also equipped with the
AN/ALQ-122 system. Originally built by
Motorola as the “Smart Noise Operation
Equipment (SNOE),” and since upgraded
by Northrop Grumman, the system has
been described as a false-target generator, which according to the International
Electronic Countermeasures Handbook
(IECH) “automatically searches, acquires
and tracks threat radar signals and generates a low-duty cycle ECM program
to deny range and azimuth.” However,
today, Mike Pefley, Director of Business
Development at Northrop Grumman’s
Land and Self Protection Systems Division, describes the ALQ-122 as simply
“a mission-unique” system. Similar to
the ALQ-155, Colonel Kelly says they’re
continuing to provide routine support at
