Ships face radio challenges in Persian Gulf during IRGC drills, UK maritime hub reports

Ships in the northern Persian Gulf have reported receiving repeated radio communications, including instructions to alter their course, which the UK Maritime Trade Operations (UKMTO) says could be linked to an ongoing Iranian military exercise.

The UKMTO, which oversees maritime security in the region, cautioned seafarers that vessels near Iranian waters could encounter similar VHF communications—radio messages sent on very high frequencies—during the Islamic Revolutionary Guard Corps' (IRGC) drills.

A commander of the IRGC Navy, Rear Admiral Alireza Tangsiri, described the "Great Prophet 19" drills on Friday as "a message of peace and friendship for neighbouring countries" adding, "We are capable of ensuring the security of the sensitive Persian Gulf region together with neighbouring nations and standing firmly against any threats."

Tangsiri said the exercise carries a message for "non-regional countries," asserting that "their presence disrupts security in the region" and that "they cannot create lasting stability in this critical area." He explained that the drills aim to strengthen the security of international waterways, focusing on the safety of shipping and economic activities in the region.

Iranian media reported that the drill features new technologies, including vessels with speeds of 75 and 90 knots capable of launching missiles and deploying advanced mines.

Tangsiri said that adversaries of Iran "should know that we will stand against their bullying with strength and courage" and that any hostile plans "will be thwarted decisively."
