May 5, 2017 Update: Eleven more
airframes have added to the collection at UAC's Grumman Storage Yard.
All came from a sale in Australia. The new airframes added are:
152800, 152805, 152809, 162811, 162816, 152837, 153566, 153576, 163578,
153598, and 153604.
As of September 2016, the following
airframes were reported already at the Tucson storage yard:
152816, 153566, 153598, 153604.
One of the most important components to come
of the Trackers are the landing gear, as can be seen in the photo above.
Information indicates that 153598 and 153804 have already had their
landing gears removed, or were purchased without them.
This will bring the Tracker count at the UAC
Tucson Yard up to 91 airframes.
Thank you to Steve Williamson for providing
the above information.
On May 24, 2010 I had the
unique one time and one time only opportunity for a non United
Corporation (UAC) employee to get inside its Grumman Tracker Storage
Yard next to Davis-Monthan AFB and AMARC in Tucson, AZ and photograph
all of the airframes located there. United Aeronautical Corp. is
the Northrop-Grumman licensee on all of the models and variations of the
S2, C-1 an E-1B Aircraft. Not only do they provide certified spares from
their aircraft, as an ISO and FAA certified facility, they also produce
all of the spares for these aircrafts. They have Northrop-Grumman's
complete data packages, and they even manufacture and supply the landing
It should be noted that UAC is
the largest provider of spare parts for the Grumman S-2 aircraft that is
still 60 years after being developed still in use with several counties
as a military aircraft along with being used an air tanker in the US,
Canada and France. All of the airframes are parked in neat rows
throughout the yard in order to facilitate the removal of parts for use
on active aircraft. Any parts that have been removed and stored
outside are in organized rows like the airframes and the facility is
neat and clean. You will notice that almost all of the
airframes are missing wheels and struts, as they have been the most
required items. At this point UAC is actually beginning to
manufacture wheels to keep the S-2s flying. Rudders and nose cones
have also been items in demand as one looks at the photos. This
was a great opportunity for me to get into the yard and record these
great aircraft and I want to thank UAC management for allowing this rare
For the Tracker enthusiast
this is the Mother Lode. There were (80) Tracker, (11) Tracer and
Trader airframes on site. As the photos show I got to photograph
them as they last served with the US Navy. Most of the photos have
a nose on shot and a tail shot, unless it was at the end of the row
where I had enough room for the full side view photograph. Many of
the tail numbers are still plainly visible along with the Navy Bureau
Number under the horizontal stabilizer facilitating aircraft
identification. In other cases where the tail was removed or a
Bureau Number had been painted over I had to use Photoshop magnification
or contrast techniques to look through the paint to identify the number.
In some cases the AMARC number was all I had from which I could also the
use a data base to determine the Bureau Number. There a groups of consecutively numbered aircraft, the largest being
