“We are aware of the increase in Iranian naval operations within the Arabian Gulf, Strait of Hormuz and Gulf of Oman. We are monitoring it closely, and will continue to work with our partners to ensure freedom of navigation and free flow of commerce in international waterways,” Captain William Urban, chief spokesman for US
Central Command, told CNN.
The Strait of Hormuz is a strategically critical passageway linking the Persian Gulf to the Arabian Sea that is crucial to international shipping and particularly for global energy supplies.
While the US
sees no immediate signs of hostile intent from Iran
, the IRGC show of force has US
military intelligence deeply concerned for three fundamental reasons according to officials:
- The exercise comes as rhetoric from the IRGC towards the US has accelerated in recent days.
- It appears the IRGC is ramping up for a larger exercise this year than similar efforts in the past.
- The timing is unusual. These types of IRGC exercises typically happen much later in the year.
There is “major concern” because of these factors, one official said.
As of now, the US
assesses the IRGC has assembled a fleet of more than 100 boats, many of them small fast moving vessels. It’s expected Iranian air and ground assets including coastal defensive missile batteries could be involved.
Hundreds of Iranian troops are expected to participate and some regular Iranian forces could be involved as well.
The IRGC exercise comes as the US
has only one major warship, the USS The Sullivans inside the Persian Gulf, several officials say. Other US
warships are nearby and there are numerous combat aircraft in the region.
military has been trying to encourage other nations in the region, especially Saudi Arabia
to take a strong line on keeping the Gulf open in the face of rising Iranian rhetoric. They have also expressed concern about keeping open the waterways off Yemen
where Iranian backed rebels have attacked oil tankers.
Defense Secretary James Mattis, responding to rising Iranian rhetoric said on Friday, “Iran
has threatened to close the Strait of Hormuz. They’ve done that previously in years past. They saw the international community put — dozens of nations of the international community put their naval forces in for exercises to clear the straits. Clearly, this would be an attack on international shipping, and — and it would have, obviously, an international response to reopen the shipping lanes with whatever that took, because of the world’s economy depends on that energy, those energy supplies flowing out of there.”
