Alenia Aeronautica Plans to Go It Alone With MALE UAV Project
(Flightglobal)
Alenia Aeronautica is looking for a partner to develop a medium-altitude, long-endurance
unmanned air system to rival the Franco-British venture announced earlier this year by
BAE Systems and Dassault Aviation.

Boeing announced Tuesday that its stealthy killer drone the “Phantom Ray” had flown for
the first time. The flight, from Edwards Air Force Base, California, lasted just 17 minutes.
Improved AirMule Resumes Flight Testing
(Flightglobal)
The prototype of Urban Aeronautics' AirMule ducted-fan unmanned air vehicle has
resumed flight testing after the company completed a four-month systems and structural
upgrade. According to the Israeli company, the AirMule is now flying with an expanded
suite of sensors and a new, energy-absorbing wheeled landing gear.
China Targets UAS as Growth Sector
(Aviation Week)
The display of dozens of unmanned-aircraft models at last November’s Zhuhai air show
made it clear that China, industrially and militarily, is moving rapidly to catch up—and
perhaps ultimately overtake—the West in this burgeoning sector of aerospace.
A Drone for the Air Force is What They Are Aiming For
(Gulf News)
Abu Dhabi: Designing an unmanned aircraft for the UAE Air Force is topmost on the
minds of five Emirati students who will travel to the US later this year for an international
convention on unmanned aircraft. The five-member team won an all-expense-paid trip to
the US to participate in the Association for Unmanned Vehicle Systems International
(AUVSI) convention by winning a competition to design, build, and pilot a remote-
controlled unmanned aircraft.
Arlington Police to Keep Aerial Drone for Surveillance
(KRISTV - NBC)
An unmanned drone may soon help Arlington, Texas police provide a watchful eye over
the city. Grant money from the U.S. Department of Homeland Security brought the city's
first unmanned drone for the Super Bowl, but Arlington hopes to put it to use full time.
Predator Drone Program Seen as Valuable Weapon Against Terror
(The Press-Enterprise)
Inland Rep. Jerry Lewis could never have given the foundering Predator program the
$400 million boost it needed 15 years ago under the nation's current policy against
earmarks, the oft-criticized spending directives that congressional members, until
recently, slipped into federal spending bills. "While earmarks are off board at this
moment, they are not the center of original sin," said Lewis, R-Redlands. "Predator has
played a major role in the challenges we've faced in the (Middle East) region."
IDEF 2011: New Turkish Rotary UAV Unveiled
(Shephard)
Turkish Aerospace Industries (TAI) used the IDEF 2011 exhibition in Istanbul to unveil a
new rotary UAV aimed at army and navy requirements. The project, which was launched
in 2010, initially saw the company take a manned Mosquito XE ultralight helicopter and
convert it for autonomous use.

Experts Warn the Free Ride for UAVs is Ending as Spending Constraints Loom
(Foreign Policy)
The most important aspect of the comfortable environment for UAVs has been financial,
experts said at the Institute of International Strategic Studies conference, "The Future of
Unmanned Air Power." Air Force Col. Dean Bushey warned that because of the weak
economy and looming defense budget cuts, the "fiscally permissive" environment will no
longer exist and said that "we can no longer just say 'buy more and send it to theater'; we
now have to be efficient and effective in our use."
Exclusive: Northrop Unveils Firebird MALE Aircraft
(Aviation Week)
Northrop Grumman will unveil its Firebird aircraft during Empire Challenge. Despite
mature work in the unmanned rotorcraft, airship and high-altitude UAS markets,
company officials have remained unsatisfied at the dominance of General Atomics in the
medium-altitude, long-endurance UAS market with their Predator, Reaper and Gray
Eagle designs.
Follow-Up: Will Firebird Hit the Market Suite Spot?
(Aviation Week)
The biggest advantage of the new design could be easier integration of payloads.
Firebird has a payload architecture designed for "plug and play", with a payload bay
located on the center of gravity, making it less sensitive to payload mass. Combined with
the piloted option (avoiding airspace restrictions and cumbersome regulations) this could
make a huge difference to the money and time required to get new sensors off the test
bench and into combat.
Video: Famed Spaceship-Maker Gives Spy Drones a Try
(Wired Magazine – Danger Room)
The legendary aerospace designers at Scaled Composites are unveiling a new spy plane
that can snoop on the unsuspecting four different ways, and it doesn’t need a human in
the cockpit to fly. Scaled Composites is best-known for its private spacecraft, but Scaled
is also a division of the giant defense contractor Northrop Grumman.
DRC’s Twin Wins Prop Up Air Force Unmanned Aircraft Program
(Washington Technology)
Dynamics Research Corp. will continue to provide engineering and technology services
to the Air Force, having won a pair of two-year delivery orders worth a combined $24.5
million. These contracts allow DRC to continue its efforts supporting mission-critical
services in conjunction with the Air Force’s Unmanned Aircraft System (UAS)
Predator/Reaper program, according to a May 9 company announcement.
China Succeeds Its Largest Unmanned Helicopter’s Debut
(International Business Times)
An unmanned helicopter, model number "V750" , the largest in China so far, on Saturday
successfully completed its debut in Weifang, a city in east China's Shandong Province,
according to Xinhua. The V750 unmanned helicopter is the first medium-sized unmanned
helicopter in China.
