Turkey-based BMC Power, a subsidiary of BMC Automotive and Trade Industry, will equip Sefine Shipyard’s Marlin unmanned surface vessel (USV) with its Azra Marine diesel engine under an agreement signed between the two companies and Seft Engineering at the 16th International Defence Industry Fair (IDEF) held from 25 to 28 July in Istanbul.

Seft Engineering is responsible for integrating the diesel engine on the USV. The USV will be equipped with two Azra Marine diesel engines.
