The Royal Navy's HMS Lancaster successfully seized a substantial haul of illegal drugs valued at £5.4 million while operating in the northern Arabian Sea.

The operation unfolded after HMS Lancaster's Wildcat helicopter detected suspicious activity involving two boats operating closely together during nighttime hours.

Upon observing what appeared to be packages being transferred from a small fast boat to a traditional fishing vessel known as a dhow, the Portsmouth-based frigate, which is assigned to operations out of Bahrain, promptly deployed a team of Royal Marines and sailors to intercept the suspected smugglers.

A representative from the Royal Navy reported that the observed activity was indicative of a drug-smuggling operation.

As HMS Lancaster approached the scene at full speed, the smugglers attempted to evade capture by discarding their illegal cargo into the sea.

However, the presence of the helicopter and the crew on the frigate's bridge ensured continuous surveillance of the situation.

After the packages were reportedly thrown overboard, the crew of HMS Lancaster's sea boat retrieved the drugs from the water and transported them back to the ship for further analysis and testing.

In total, the operation resulted in the recovery of 340 kilograms of heroin and 83 kilograms of methamphetamine.

Commander Sam Stephens, the commanding officer of HMS Lancaster, expressed pride in the professionalism and dedication of his team during this successful mission aimed at disrupting illegal drug trafficking.

Able Seaman Tom Urie noted the personal fulfillment associated with such operations, emphasizing the importance of their work in impacting drug distribution back home.

HMS Lancaster is currently participating in the international Combined Task Force 150, which is dedicated to targeting illegal activities in the Middle East region.
