RF & Microwave Technology
DATA-BUS
MIL-STD-1553
TRANSFORMERS
Raytheon Technologies is developing a prototype for the U.S. Army's TITAN ground station, which will find and
track potential threats by quickly combing through immense amounts of sensor data. (Raytheon Technologies)
haven't yet defined. Collins has invested
in software-defined radios,
which can add capabilities through fast,
frequent system updates; RF (radio frequency)
products that perform multiple
functions; and open-systems architecture,
an approach to design that allows
for quick, efficient modifications.
Ensuring the integrity of highly sensitive
military transmissions is the work
of Raytheon Intelligence & Space. Their
products include Advanced Extremely
High Frequency (AEHF) satellite communications
terminals and antennas,
modems, and cybersecurity tools that
can be installed on many platforms and
work in many domains. The company
supplies much of the DoD's existing
communications infrastructure for
many highly encrypted missions. Part
of JADC2 is trying to determine how to
proliferate this level of encryption to a
variety of different platforms.
Communications equipment must
be robust and undetectable. Unlike
commercial wireless modems that are
built to reveal themselves for anybody
who is looking for them, military communications
equipment must do exactly
the opposite.
Resilient Networks
Securing the network and its data is
only one of the challenges facing JADC2.
Another is to keep the network running
even after it's attacked. Just as modern
communications systems are becoming
more resilient by fielding multiple small
satellites (as opposed to large, singlesatellite
systems), JADC2 calls for deliberate,
built-in redundancy - an approach
where sensors and platforms can not
only create information but relay it,
building bridges between the military
services' historically disparate networks.
In a 2021 demonstration at Wright
Air National Guard base in Salt Lake
City, for example, Collins Aerospace
showed that a KC-135 aircraft - a plane
traditionally used only for refueling
bombers and tactical fighters - can
double as a communications hub to the
joint force. Using Collins technology,
the KC-135 transmitted data from a
ground unit including images and positioning
data with different levels of
classification a key concern in joint and
coalition operations where commanders
need to limit the detail of information
they share.
" Those tankers are in a prime position
to be closer to the target environment,
to support joint efforts and be an
effective tool that's not been realized, "
said Braxton Rehm, a retired U.S. Air
Force F-16 pilot and the director of
JADC2 requirements and demonstrations
at Collins. " They have available
space, available power, and available
time on station while they're doing
their refueling mission. They can be a
part and a player in all of that. "
