China's Norinco displayed a model drone assembly line at the Eurosatory defence exhibition in Paris.
The model depicted the manufacture of drones including the BZK-005E reconnaissance aircraft, covering parts production, final assembly and testing.
A graphic in the booth described how explosives and propellants used in the drones are made.
A banner behind the display read “Norinco defence localisation”.
The BZK-005E is currently operated in Indonesia, Mauritania and reportedly Sudan.
