China is driving use of armed drones in Mideast, says British think tank
By: Zeina Karam, The Associated Press
BEIRUT — The use of armed drones in the Middle East, driven largely by sales from China, has grown significantly in the past few years with an increasing number of countries and other parties using them in regional conflicts to lethal effects, a new report said Monday.
The report by the Royal United Services Institute, or RUSI, found that more and more Mideast countries have acquired armed drones, either by importing them, such as Jordan, Iraq, Saudi Arabia and the United Arab Emirates, or by building them domestically like Israel, Iran and Turkey.
China has won sales in the Middle East and elsewhere by offering UAVs at lower prices and without the political conditions attached by the United States.
The Associated Press reported earlier this year that countries across the Middle East locked out of purchasing American-made drones are being wooed by Chinese arms dealers, helping expand Chinese influence across a region vital to American security interest.
It noted the use of Chinese armed drones across Mideast battlefields, including in the war on Yemen, employed by the Emirati Air Force. Iran has also violated Israeli airspace with armed UAVs from bases in Syria, provoking armed Israeli response on the suspected bases.
The RUSI report, titled “Armed Drones in the Middle East: Proliferation and Norms in the Region,” said that by capitalizing on the gap in the market over the past few years, Beijing has supplied armed drones to several countries that are not authorized to purchase them from the U.S., and at a dramatically cheaper price.
"China, a no-questions-asked exporter of drones, has played and is likely to continue playing a key role as a supplier of armed UAVs to the Middle East," it said.
The report explored where and how each of the states have used their armed drones and whether they have changed the way these countries approach air power. It found that Iran, the UAE and Turkey all changed the way they employ air power after they acquired armed drones.
For Turkey and the UAE, armed drones enabled them to conduct strikes in situations where they would not have risked using conventional aircraft, it said. Iran developed armed drones from the outset specifically to project power beyond the reach of its air force, which is hamstrung by obsolete aircraft and sanctions, the report added.
The report said it remains to be seen whether and how the loosening of restrictions on the export of armed drones by the Trump administration will alter dynamics in the region. The administration in April permitted U.S. manufacturers to directly market and sell drones, including armed versions, although the government must still approve and license the sales.
Aniseh Bassiri Tabrizi, who authored the report along with Justin Bronk, said proliferation of armed drones in the Middle East is unlikely to stop and could accelerate despite changes introduced by the U.S. administration.
“Over the past two years the sales have increased massively and they are likely to increase even more,” she said. “This kind of collaboration is just going to grow especially in cases where countries don't have the capacity to build them themselves.”

Pratt & Whitney Awarded Contract for F135 Engine Modernization Study
Seapower Staff EAST HARTFORD, Conn. — Pratt & Whitney, a division of Raytheon Technologies Corp., has been awarded a $1.5M contract to conduct an F135 modernization study and operational assessment by the F-35 Joint Program Office to determine specific propulsion system growth requirements for Block 4.2 F-35 aircraft and beyond, the company said in an Oct. 20 release. The study is expected to conclude in March 2021. “This award is a significant milestone for the program and the warfighter, as we look to ensure the F135 propulsion system continues to provide the foundation for all air vehicle capability requirements over the full lifecycle of the F-35,” said Matthew Bromberg, president, Pratt & Whitney Military Engines. “As we look to the future, growth in aircraft capability must be met with matched propulsion modernization. Fortunately, the F135 has ample design margin to support agile and affordable upgrades that will enable all F-35 operators to keep pace with evolving threat environments.” Under this award, Pratt & Whitney will assess F135 engine enhancements required to support future F-35 weapon system capability requirements across all F-35 variants beginning with Block 4.2 aircraft. The scope of the assessment focuses on enhancements addressing improvements to up and away thrust, powered lift thrust, power and thermal management capacity, and fuel burn reduction. Designed with the knowledge that operational environments will evolve and threats will advance, the F135 is postured to meet future F-35 capability requirements. Its modular design and advanced digital architecture allow for the agile development and spiral insertion of both hardware and software upgrades. As part of the study, Pratt & Whitney's GATORWORKS organization will complete the conceptual design and analysis of multiple F135 Engine Enhancement Package (EEP) growth options with phased insertion plans. Leveraging significant U.S. Government and Pratt & Whitney investment in next generation adaptive propulsion technologies, Pratt & Whitney's EEP approach offers low risk, variant-common upgrade options for the F135 that provide increased performance aligned with the program's continuous capability development and delivery strategy and serve as a critical enabler for future capability growth of the F-35 weapon system. The combat-proven F135 is the most advanced operational fighter engine in the world, delivering 26% more thrust, 116% more powered lift, and more than a 300% increase in power and thermal management over 4th generation fighter engines – all with a demonstrated mission capability rate of greater than 94%. “Built upon decades of combat propulsion experience, the F135 provides the warfighter with a critical technological advantage over adversaries at an unparalleled value to the taxpayer,” said Bromberg. “With more than 40,000 pounds of thrust, unmatched low-observable signature, world-class thermal management, and innovative engine control system, the F135 is a critical enabler of the F-35 weapons system and of operations conducted in advanced threat environments – a core element of the National Defense Strategy.” https://seapowermagazine.org/pratt-whitney-awarded-contract-for-f135-engine-modernization-study/
