2/20/2008 - Testing of the Battlefield Airborne Communications
Node (BACN) is continuing forward. During the month of February,
Bombardier Global Express test aircraft N901GX has flown test
sorties out of NAS North Island, CA in support of the program.
The aircraft has been changed considerably since it was last
seen in SoCal, near the end of 2007. It now appears to be outfitted
in the Sentinel R1 configuration, including the lower radome,
which would normally contain the Raytheon built Airborne Stand-Off
Radar (ASTOR). 901GX was originally brought in to be used as
a test bed for the BACN system in 2007, making its first flight
with the equipment onboard in August of that year.
In January 2007, NASA's WB-57 #926 flew numerous test missions
into the Edwards AFB range in support of BACN, while being based
out of March ARB. NASA 926 was the first aircraft to have BACN
technology installed, and it has been utilized in the program
on and off since the beginning. The BACN system is designed
to be used at high altitudes, which makes the high flying WB-57
a good choice for a flight test bed. 926 had flown earlier BACN
test missions from MCAS Miramar in 2007, and it now wears numerous
stickers from the various Miramar squadrons on it's nose.

The Battlefield Airborne Communications Node (BACN) is a system
that offers the ability to link communications of various types
and modes in both data and voice form, between numerous assets
on the battlefield. The system basically acts as a communications
hub that allows various entities across multiple services to
pass voice, text, video and other data, using equipment that
might otherwise be incompatible when used directly. This system
is intended to ultimately be utilized on Unmanned Aerial Vehicles.
Both the WB-57 and Global Express test aircraft are scheduled
to participate in the Joint Expeditionary Force Experiment (JEFX)
in early 2008, which will be based at Nellis AFB, NV.
