Conflicting Reports Over Iranian Strike on Hormuz Navigational Aids

Conflicting reports of an Iranian attack on Omani navigational aids on Didamar Island signal a potential shift toward targeting the safety infrastructure that governs the Strait of Hormuz. If Iran is now striking the tools used to marshal marine traffic, the risk to every vessel transiting the world’s most critical chokepoint has fundamentally changed.

Reports of an attack on Didamar Island, located 10nm north of the Musandam peninsula, emerged after social media footage showed smoke in the area. It is unclear if the smoke originated from the island or a stricken tanker positioned behind it. The Iranian Fars News Agency claimed navigational aids on the southern reefs were struck to prevent the unauthorized transit of ships. However, a senior Omani official told the Maritime Executive that the island’s facilities were not hit. Satellite imagery from November 10 supports the Omani denial, showing no obvious damage to the lighthouse or the 25m radar tower.

Why it matters

Didamar Island is the site of the Hormuz Control Centre, where the Royal Navy of Oman marshals traffic through the Traffic Separation Scheme. The radio relay towers, Channel 16 communications, and radar maintained by Arabian Maritime and Navigation Aids Services (AMMAS) are the primary tools for safe navigation. Any degradation of these aids forces masters to navigate the Strait with reduced situational awareness, increasing the risk of collisions in Omani territorial waters.

The Iranian claim of targeting infrastructure to block unauthorized ships suggests a move to weaponize navigational safety. By attempting to justify strikes on Omani-owned aids, Tehran is asserting a right to dictate who can use the Strait, directly challenging the right of innocent passage. This puts every charterer and owner at the mercy of Iranian definitions of what constitutes an authorized transit.

For insurers and shipowners, this development signals that Omani territorial waters are no longer a sanctuary. Following previous IRGC transgressions against Omani ports in Duqm and Salalah, a strike on Didamar would represent a grave breach of sovereignty against the neutral party that consistently rescues wounded mariners and crews in the region. The risk is that the safety infrastructure of the Strait is now a legitimate target in the eyes of the IRGC.
