The Jordanian air force has put up for sale six Chinese-made CH-4B drones.

It’s unclear why Amman is trying to get rid of its CH-4s just three years after acquiring them. But it’s possible the divestment is related to Jordan’s ongoing efforts to source Predator-style drones from the United States.

“The general command of the Jordanian armed forces ... announces its desire to sell the following aircraft,” the defense ministry in Amman stated on June 3, 2019.

The for-sale list includes four CASA transports, an old C-130B cargo plane, 12 Hawk 63 training jets, six MD530 helicopters and six CH-4s.

Jordan bought the missile-armed CH-4s, which are broadly similar to General Atomics’ early-model Predators around 2016 after the administration of U.S. president Barack Obama rejected Amman’s request for MQ-1 Predators.

General Atomics also makes the larger MQ-9 Reaper drone.

The Jordanian air force’s No. 9 Squadron operated the Chinese-made drones. The same unit operates the air force’s other unmanned aerial vehicle, including Schiebel S-100 Camcopters and Leonardo Falcos.

It wasn’t until May 2018 that the Jordanian air force displayed a CH-4 in public.

“Marketed by Aerospace Long-March International Trade, the CH-4B has found a good market here in the Middle East, in part due to the reluctance of U.S. authorities to sell armed UAVs to their allies in the region,” Al-Monitor reported.

“Egypt, Saudi Arabia, the United Arab Emirates and Iraq have all acquired the CH-4B armed version, and the type has been employed widely on operations in Yemen and against Daesh targets in Iraq.”

But Jordan never gave up trying to get permission to buy American drones, which are widely considered as having better sensors, weapons and communications links than the Chinese drones do.

Amman perhaps believes Pres. Donald Trump is more open to approving drone sales to Middle East customers, not only for the military benefit but also as a way of commercially competing with China.

“The Donald Trump administration is worried that weapons carrying the ’Made in China’ label are becoming ubiquitous on Middle East battlefields,” Al-Monitor explained.

In increasing numbers, traditional U.S. allies are turning to Beijing for technologies that the United States is constrained from exporting as a signatory of international arms control treaties. The Pentagon is increasingly concerned that China’s growing arms sales give the country more clout to secure an economic and military foothold and relationships with U.S. allies in a region where defense officials often control the purse strings.

"It's potentially a tool for them to develop closer defense and military ties, particularly for future access,” Assistant Secretary of Defense for Indo-Pacific Affairs Randall Schriver told Al-Monitor at a recent Pentagon briefing. “China is less disciplined, and so there's a proliferation risk as well to regimes that we would regard as not necessarily responsible.”

Of course, it’s also possible that Jordan aims to replace the CH-4s with better Chinese-made drones.

Based on customers’ experience deploying the CH-4, drone-maker China Aerospace Science and Technology Corporation developed the larger and more powerful CH-5.

“The CH-5 offers a … 441-pound internal payload for sensors and a … 2,205-pound external payload, permitting it to carry up to 16 precision-guided missiles underwing,” Jane’s reported. “This vehicle is roughly equivalent to the MQ-9 Reaper, although it retains a piston engine instead of the Reaper’s turboprop.”
