SnowGoose: UAVs Enter the Airlift Business

ST INIGOES, Md., July 16, 2003 – The popular idea of
unmanned aerial vehicles is that they are like aggrandized
radio-controlled planes, good only for reconnaissance and
scouting.
But the UAV flight demonstration at Naval Air Station
Patuxent River's Webster Field July 14 showed there's more
to the story.
These days UAVs carry weapons. Some Predator UAVs, now
flying missions over Iraq and Afghanistan, are armed with
Hellfire missiles. The Air Force and Navy are working
together to develop unmanned combat aerial vehicles capable
of delivering ordnance with pinpoint accuracy in combat
zones deemed too "hot" for manned aircraft.
And UAVs also may start doing airlift missions. A Canadian
firm has developed a UAV capable of delivering supplies to
special operations forces. One, called the SnowGoose, can
be dropped from another aircraft or launched off the back
of a Humvee.
The SnowGoose promises pinpoint delivery of small cargoes.
U.S. Special Operations Command has bought five of the
aircraft, according to MIST Mobility Integrated Systems
Technology, Inc. U.S. officials said the command could
ultimately buy 74 of the UAVs.
The aircraft operates with a parasail and a "pusher"
propeller engine. It can operate at altitudes ranging from
200 feet to 18,000 feet. It is virtually undetectable at
altitudes of 2,000 feet or more. "That's a good thing,
because it cruises at about 35 knots," said Sean McCann, a
company representative who showed off the SnowGoose at the
flight demonstration.
The SnowGoose could be used to drop leaflets, small amounts
of ammunition, medical supplies and other equipment.
"Mogadishu would have been a perfect place for this type of
capability," said Clark Butner, a UAV specialist with Naval
Air Systems Command's special communications requirements
division. He was referring to 1993 U.S. military operations
in the Somali capital when 18 Rangers helping to conduct a
mission to capture warlords were killed.
"The Rangers didn't bring their (night optical devices)
when they went on the mission," Butner noted. "This
aircraft could have dropped NODs to them, delivered plasma
to them and dropped ammo."
A small laptop computer allows technicians to program in a
mission, which can proceed without another command from the
ground. Right now, once the mission is launched, planners
cannot change it. However, MMIST is working with the UAV
Systems Office in Huntsville, Ala., on an advanced concept
technology demonstration that will allow planners to change
the mission at any time.
"The (Airborne Guidance Unit) provides all the flight
control," McCann said. "Payload bins are automatically
released, taking wind speed and direction into
consideration. The AGU calculates the release points in
flight and are based on real-time wind measurements."
McCann stated the aircraft can change position up to six
kilometers due to varying conditions.
The aircraft doesn't need a runway, and a four-man team can
operate it. Butner said a team could learn to operate the
system in 10 days. "It's not complicated," he said. The
most complicated thing may be repacking the parasail after
a mission, he said.
Each SnowGoose costs around $250,000.
