As summer comes to a close so does the resto-
ration of the YAH-63 (model 409), a most unique
aircraft indeed. In the mid 70’s, a replacement for
the AH-1 Cobra was needed to meet the evolving
threat posed by the Soviet Union. The Cobra and its
TOW missile system was rapidly being eclipsed by
more advanced weapons and battlefield surviva-
bility was also a concern for the single engine air-
craft. Based on these and other concerns, the Ar-
my released request for proposals (RFP) for a new
Attack Helicopter. Hughes Aircraft offered what we
know today as the AH-64 Apache and Bell Helicop-
ter would submit the YAH-63.
The YAH-63 had several innovative design fea-
tures but its overall appearance was strikingly simi-
lar to the AH-1 Cobra. Many of our visitors have
commented on the fact that it looked like a mul-
tiengine Cobra with a bigger gun. Most of the rotor
system was similar to that of the Cobra, the same
underslung instead of the more complex articulat-
ed system. However, it did have a unique system to
lower the rotor head for transport by aircraft.
When the pitch change links were disconnected
the mast had a worm gear designed to spin the
blades in the opposite direction of rotation there
by allowing the mast to “Screw into” the transmis-
sion and lower the overall profile by over a foot.

YAH-63
Since the introduction of COVID-19 and everything it has brought with it, the significance
of our digital presence is greater than ever. The Internet gives us an effective platform for
showcasing what the Foundation has to offer. Our online presence is an extension of us that
never closes or sleeps giving you 24-hour access to a wealth of knowledge regarding the
Museum, its content and other important information. We are so excited about growing our
online community and hope that you will support our campaign to reach 10,000 Likes on
Facebook.
Social media is all about building relationships which is what makes social media plat-
forms like Facebook so important. Facebook gives you and I a way to connect on a more
personal level allowing us the opportunity to truly get to know one another. Facebook is
one of the simplest, yet most effective ways to communicate and to form real relationships
with real people. I am a real person, by the way, so please reach out and say ‘Hi’!
Facebook is an excellent marketing tool. It is absolutely free, which makes it perfect for
us as a non-profit. Using the internet for marketing purposes also allows us to overcome dis-
tance barriers which we experience a lot with our growing military community. Though you
may be thousands of miles away, you can still learn all about what is happening here at the
Museum. Then with a few clicks you can easily spread the word about us to all your friends
and we do love that!

THE SIGNIFICANCE OF A DIGITAL PRESENCE
UPDATE: RESTORATION COMPLETE YUH-61
Leah Dunkle - Foundation Representative
There were also provisions to mount maintenance stands
on various locations with hard point mounts. This would allow
the maintainer to set-up a work platform on the hard points
rather than try to stand on the aircraft to access the work
area.
The weapons systems the YAH-63 had were also ground
breaking, the most interesting of which was the nose mounted
cannon which employed a three barrel 30mm Gatling type
cannon! The single barrel 30mm chain gun design on the AH-
64 is a devastating weapon, one can only wonder the dam-
age that could be done with three barrels. The pilot’s station
was in the front seat and the gunner in the rear, a much more
desirable arrangement giving the pilot safer and better visibil-
ity. The weapons sight was located on the belly between the
front and back seat.
YAH-63 serial Number 73-22246 first flew in October of 1975
but Crashed in June of 1976, the second YAH was serial num-
ber 73-22247 would enter the fly-off against the YAH-64. In De-
cember of 1976 the Army selected the AH-64 and that would
go into production as the next Army Attack Helicopter. Many
speculate on what or why one was selected over the other
but the good news is the Army Aviation Museum has both ex-
amples in the collection! When the Training Support Facility
(TSF) is complete they will both be on exhibit in the historical
line-up as part of the evolution of Army aviation.

LEGACY PAVERS
I am very excited to announce that Paver
Order #17 was submitted on August 31st and
they should arrive sometime in early November.
We always look forward to the installation of new
pavers because we know that each and every
one of them plays a significant role in the story of
the U.S. Army Aviation Museum.
Paver Order #18 is already under way so I
hope that you will consider contributing to the
Legacy Paver Program. Legacy Pavers are a
beautiful way to celebrate your military service or
