10/22/2007 - The US Navy's Air Test and Evaluation Squadron
Three One (VX-31) handles the majority of weapons testing that's
conducted on various Naval aircraft platforms. As such, they
typically have at least one example of each Naval/Marine aircraft
that's capable of dropping or launching weapons on hand, including
helicopters.
The VX-31 "Dust Devils" are based at China Lake Naval
Air Weapons Station, along with their companion unit, the VX-9
"Vampires". VX-9 typically focuses on operational
evaluation of attack, fighter, and EW aircraft, their weapons
systems, and the development of tactical procedures for the
fleet. The Dust Devil's job basically deals with testing the
actual equipment in a technical sense, whereas the Vampires
are more involved with evaluating the equipment in 'real world'
scenarios, to see how the average combat pilot can use it in
the fleet. Like VX-31, VX-9 also has numerous Naval aircraft
types available to them.

Until recently, VX-9 had three known AH-1W Cobra models available
in their squadron for evaluation needs. These included: #740
BuNo 163935, #741 BuNo 163936 and #742 BuNo 165358. In May of
2006, four of the first helicopters from the USMC AH-1Z and
UH-1Y 'Light Attack' upgrade program left Patuxent River NAS
and made their way out to the desert at China Lake. Initial
testing on the two 'new' aircraft models had already been conducted
at Pax. It was now time to begin Operational Evaluation under
VX-9, before the two aircraft started to be delivered to combat
units in the fleet. The aircraft the Vampires received were
two AH-1Z models: BuNo 166478 and 166479, and two UH-1Y models:
BuNo 166475 and 166476.

The AH-1Z "Super Cobra" and UH-1Y "Iroquois"
upgrade program is extensive. Each 'new' aircraft will be created
out of existing AH-1W and UH-1N models already in the USMC fleet.
The new AH-1Z upgraded model includes a state of the art "glass"
cockpit, integrated helmet-mounted sighting system, upgraded
engines and drive-train, 10,000-hour airframe life and a new
hinge-less, bearing-less, composite four-bladed rotor system
(two added blades). This more than doubles the payload capacity
and increases the aircraft’s functional flight envelope
by 80 percent. The AH-1Z is 84 percent identical in its requirements
when compared with the new UH-1Y. This will reduce the logistical
demands of the Marine Light Attack Helicopter squadrons when
deployed, since the LAHS units fly both aircraft.
The basic H-1 "Huey" has been produced over 16,000
times in various variants, since 1956. The UH-1Y is the most
significant upgrade ever made to the basic H-1 model. Similar
to the AH-1Z, the UH-1Y upgrade includes a new four-bladed,
all-composite and ballistically tolerant rotor system, upgraded
engines and transmissions integrated into a digital "glass"
cockpit featuring multifunction flat panels, increased payload
capabilities, and crash-worthy seating for all crew and passengers.
The upgrade also provides increased load carrying ability, greater
range and survivability, smaller logistical footprint and easier
maintenance requirements within the squadrons.

As the AH-1Z / UH-1Y Light Attack upgrade program moves along,
it appears that VX-31 has now been given their own versions
of the two new aircraft, which will undoubtedly be utilized
extensively for weapons testing well into the future. On October
20th, Dan Stijovich happen to catch two of the new upgraded
helicopters that have been assigned to VX-31 fly into El Centro
NAF, CA. "Coso 411 Flight" included UH-1Y #411 BuNo
166756 wearing the Dust Devil's 'DD' code, and AH-1Z #005 BuNo
166759, also wearing the Dust Devil's 'DD' code. It's unknown
if these are the only examples of the new helicopters that they
have received. There doesn't appear to be any special test equipment
attached externally to the aircraft as of yet. Future test programs
will most likely see some modifications made to the aircraft.
The USMC H-1 Light Attack Upgrade Program will eventually replace
the current fleet of AH-1W and high time UH-1N aircraft by providing
a total of 180 AH-1Z and 100 UH-1Y new zero-time aircraft to
the fleet.
