Late on 15 February 2020 the frigate HMS Montrose, working in direct support of Combined Task Force 150 under Australian command, tasked her Wildcat helicopter after a suspicious dhow was seen in an area of the Gulf of Oman known for drug smuggling.[1][2] By sunrise on 16 February several packages could be seen floating near the dhow, and they were recovered and determined to be hashish.[1][2]

Royal Marine Commandos then boarded the dhow and secured it for search by a Royal Navy boarding team.[1][2] The dhow’s master admitted the packages in the water had come from his vessel, and a thorough search found a further cache of hashish hidden aboard.[1][2]

Together with the drugs recovered from the sea, the seizure totalled 1,045 kg of hashish, worth an estimated US$538,860 regionally or about 6 million pounds on British streets.[1][2] The task force commander said the crew had stopped the smuggler from ditching the cargo and kept the drugs from reaching their destination.[1][2]
