Cargo drone makes debut in Afghanistan

KABUL (AP): The US military is testing a revolutionary new drone for its arsenal, a pilot-less helicopter intended to fly cargo missions to remote outposts where frequent roadside bombs threaten access by road convoys.

Surveillance drones for monitoring enemy activity and armed versions for launching airstrikes have become a trademark of America's wars in Afghanistan, Iraq and elsewhere in the Middle East. But this is the first time a chopper version designed for transport has been used operationally.

Two unmanned models of the Kaman K-MAX helicopters and a team of 16 company technicians and 8 Marines are conducting a 6-month evaluation programme for the new craft at Camp Dwyer, a Marine Corps airfield in the Garmsir district of southern Helmand Province.

The craft have flown 20 transport missions since the inaugural flight on December 17, said Maj. Kyle O'Connor, the officer in charge of the detachment.

"Afghanistan is a highly mined country and the possibility of improvised explosive devices is always a problem moving cargo overland in a convoy," O'Connor said.

"Every load that we can take off of a ground convoy reduces the danger and risk that our Marines, soldiers, and sailors are faced with," he said. "With an unmanned helicopter, even the aircrew is taken out of harm's way."

The Marines from Unmanned Aerial Vehicle Squadron 1 lead the missions and deliver the cargo into combat drop zones, while contractors operate and maintain the two aircraft.

The craft's onboard computer uploads the mission plans, enabling them to fly on autopilot. But an operator at base control monitors progress and can step in and override the autopilot for manual operation if any problems occur, or if the drone must be redirected in mid-flight.

The K-MAX is the latest in a series of Kaman synchronised twin-rotor helicopters dating from the 1950s. The unusual arrangement, with two side-by-side pylons on the helicopter's roof supporting counter-rotating blades, results in exceptional stability while hovering and allows pinpoint cargo delivery.

The manned version of the K-MAX helicopter first appeared in the 1990s, and the pilot-less prototype was unveiled in 2008. It can carry a maximum payload of 6,855 pounds (3,100 kilograms) and costs about USD 1,100 an hour to operate, several times less than any manned helicopter.

After a six-month test period, the military will determine whether to put the craft into regular operational use.
