On 29 July 2021, the oil tanker MT Mercer Street was attacked near the coast of Oman while sailing to the United Arab Emirates (UAE) from Tanzania.

The investigation found the third UAV was loaded with military-grade explosives, which created a 6-foot hole in the topside of the pilot house and badly damaged the interior.
