The Islamic Revolution Guards Corps (IRGC) Navy has announced a major strategic expansion of Iran’s defensive perimeter in the Strait of Hormuz, warning that it will not allow any violation of the country’s territorial waters or national interests.

Rear Admiral Mohammad Akbarzadeh, the political deputy of the IRGC Navy, said on Tuesday that Iran has fundamentally redefined the operational boundaries of the strategic waterway.

What Iran considers the scope of the strait has been expanded, stretching from the coasts of Jask and Sirik to beyond the Greater Tunb Island, redefined as a strategic zone, he explained.

“It has expanded from a width of 20 to 30 miles in the past to over 200 to 300 miles, that is, 500 kilometers, from Jask and Sirik to beyond Qeshm Island and Greater Tunb. This is a complete crescent.”
