Zephyr is likely for Afghanistan and Iraq missions

Developed by British firm Qinetiq, the latest versions have an 18.2m (59.6ft) wingspan, 30kg (66lb) mass with a 45kt (83km/h) cruise speed. Zephyr is designed for surveillance or communications missions and has achieved flight endurances of 54h and 82.3h.

According to Flight International magazine the UAV is in demand  for the Middle East theatre.

"We are in the final throes of an agreement of how to move forward to operationally test [Zephyr] outside the USA. We are very close to getting an operational solar-powered system," Cdr Eliot Gunn of the office of the secretary of defence, advanced systems and concepts, unmanned systems joint capability technology demonstrations programme, oversight executive., told the British magazine.
 
Long-range signals intelligence is the US Department of Defense's primary interest in Zephyr, Gunn said. The DoD may also want to provide Zephyr to other "combatant commanders" beyond Afghanistan and Iraq, he adds.

A Zephyr prototype is being flown at the US Army's Yuma proving grounds in Arizona for additional testing. Zephyr 5 prototypes have been flown at the White Sands missile range in New Mexico.

Gunn says the endurance record setting prototype was called Zephyr 6, but that a contract has now been awarded for Zephyr 7.
