The Jerusalem Post on 26 September reported that German officials “imposed a ban on the same of model aircraft engines to Iran after a shipment ended up on drones used by Houthis in Yemen”, and Iran then moved to acquire similar parts from China. It is said that a small maker of engines for miniature versions of well-known aircraft was involved, with the motors sent by roundabout routes to Iran. The types of engines used in small drones are not usually seen as “military” or dual-use goods, the article giving the DLE-111 2-cylinder engine manufactured by the Chinese company Mile Haoxiang Technology as an example, and one found to have powered a “suicide drone”. Another example given is the 3W-110i B2 engine manufactured by 3W Moddellmoroten Weinhold GmbH in Hanau in Germany (and which can be used in aircraft up to 20 kg in weight). Also mentioned are gyroscopes, used in guidance systems.
