The Royal Navy frigate HMS Lancaster boarded a suspicious vessel in the Arabian Sea at last light and seized 3.2 tonnes of hashish, which the navy calls cannabis resin.[1] The boarding took place at last light on Monday 8 May 2023, days after the ship helped evacuate civilians through Port Sudan.[2]

Led by the ship’s Royal Marines detachment from 42 Commando, the boarding party found packages on the deck and, with a team of sailors, recovered nearly 200 packages weighing around 11 kg each.[2] The search found almost 200 packages, each containing around 11 kg of cannabis resin, for a total of 3.22 tonnes.[3] The haul was transferred to the warship during the night and the drugs were later destroyed.[3]

The Royal Navy put the drugs’ value at £2.5 million on the UK wholesale market.[1] The task force’s own public statement recorded the seizure on 8 May, put the weight at 3,000 kg and the value at US$6 million, and did not say whether anyone on the vessel was detained.[4]

The Lancaster was serving with Combined Task Force 150, a multinational naval force based in Bahrain that the Royal Navy commanded from January to July 2023.[1] It was the ship’s first drugs seizure since it arrived in the Middle East the previous autumn to replace HMS Montrose.[2]
