UK reveals Type 23 frigate seized smuggled Iranian missiles

In early 2022, whilst on routine maritime security operations, the Royal Navy Type 23 frigate HMS Montrose seized Iranian weapons from speedboats being operated by smugglers in international waters south of Iran.

The seizures, which occurred on January 28 and February 25, took place in the early hours of the morning. HMS Montrose’s Wildcat helicopter, equipped with radar systems, was scanning for vessels smuggling illicit goods. 

The helicopter crew spotted small vessels moving at speed away from the Iranian coast, according to navy officials.

US Navy’s destroyer USS Gridley supported efforts by deploying a Seahawk helicopter to provide critical overwatch during the operation. On both occasions, the Wildcat helicopter pursued the vessels and reported back to HMS Montrose that they could see suspicious cargo on deck.     

A team of Royal Marines approached the vessels on two Rigid Hulled Inflatable Boats before securing and searching the vessel. Dozens of packages containing advanced weaponry were discovered, confiscated and brought back to HMS Montrose, the navy stated.

The weapons seized included surface-to-air-missiles and engines for land-attack cruise missiles, in contravention of UN Security Council resolution 2216 (2015).  

The seized packages were returned to the UK for technical analysis which revealed that the shipment contained multiple rocket engines for the Iranian produced 351 land attack cruise missile and a batch of 358 surface to air missiles.    

The 351 is a cruise missile with a range of 1000kms, it is regularly used by the Houthis to strike targets in the Kingdom of Saudi Arabia and was also the type of weapon used to attack Abu Dhabi in January 2022, which killed three civilians.    

This is the first time a British Naval warship has interdicted a vessel carrying such sophisticated weapons from Iran.    

“The UK is committed to upholding international law, from standing up to aggression in Europe to interdicting illegal shipments of weaponry that perpetuates instability in the Middle East,” said Minister for the Armed Forces James Heappey.

“The UK will continue to work in support of an enduring peace in Yemen and is committed to international maritime security so that commercial shipping can transit safely without threat of disruption.”  

The UK retains a permanent presence in the Middle East, with HMS Montrose having been deployed to the region since early 2019. In the wider Gulf, HMS Montrose regularly works alongside international partners as part of the 38-nation coalition Combined Maritime Forces (CMF).

The ship has taken part in numerous successful operations to seize illicit drugs in the Gulf of Oman. This year alone, the frigate has intercepted nearly £100 million of illegal narcotics.
