Four speedboats from the Iranian Revolutionary Guard Corps harassed the Arleigh Burke-class guided-missile destroyer USS Nitze (DDG 94) during a transit of the Strait of Hormuz earlier this week. The incident comes a month after Iranian officials talked tough about closing the maritime chokepoint if Iran was attacked.
According to a report from FoxNews.com, at least two of the speedboats came within 300 yards of the destroyer. The Nitze reportedly tried to communicate with the Iranian vessels a dozen times but received no response before the close pass. The destroyer fired warning flares and sounded its whistle five times in an effort to warn off the Iranian vessels, which approached with uncovered weapons. The speedboats in question appeared to have heavy machine guns mounted forward, and had them turned towards the destroyer.
"The Iranian high rate of closure on a United States ship operating in accordance with international law while transiting in international waters along with the disregard of multiple warning attempts created a dangerous, harassing situation that could have led to further escalation including additional defensive measures by Nitze," an unidentified defense official told USNI's blog.
The guided missile destroyer USS Mason (DDG 87), a sister ship of the Nitze, was also making a transit of the Strait of Hormuz during the incident. The two 9,200-ton vessels are Flight IIA Arleigh Burke-class destroyers, with a single five-inch gun, a 32-cell Mk 41 VLS, a 64-cell VLS, a Mk 15 Close-In Weapon System, and two triple 324mm torpedo tube mounts.
The IRGC has been involved in past incidents, including the 2015 seizure of a Marshall Islands-flagged merchant vessel and the temporary detention of U.S. Navy sailors who strayed into Iranian waters this past January. That force also was involved in incidents in December 2007 and January 2008 where U.S. Navy ships were harassed in a similar manner during a transit of the Strait of Hormuz.
