The Arleigh Burke-class guided missile destroyer USS Mahan (DDG 72) fired warning shots at a group of Iranian vessels in the Persian Gulf on Jan. 8. The incident comes less than two weeks before President-elect Donald Trump takes office.
According to Reuters, the shots were fired after the Iranian vessels ignored requests by radio to slow down as they approached the American warship and came within 900 yards.
Similar harassment took place this past summer, with Iranian speedboats making close passes to USS Nitze (DDG 94) and USS Squall (PC 7), which also fired warning shots.
Iranian-backed Houthi rebels in Yemen fired on U.S. Navy vessels using Iranian-built Noor anti-ship missiles this past October. The destroyer USS Mason (DDG 87) defeated three attacks in the space of a week, and USS Nitze carried out a retaliatory strike on radar sites. This past September, while campaigning for the White House, Trump vowed that Iranian vessels harassing U.S. Navy forces would be "shot out of the water."
The Iranian vessels were described in the Reuters report as "fast attack vessels." These vessels, sometimes called "Boghammers," are speedboats with a variety of weapons, including rocket launchers and heavy machine guns.
According to "Combat Fleets of the World," Iran has over 180 of these vessels. During the Iran-Iraq War, they were used to attack oil tankers.
A July, 1988 skirmish between those speedboats and the cruiser USS Vincennes and the frigates USS Sides and USS Elmer Montgomery lead to the downing of an Airbus passenger jet.
The USS Mahan is the first of seven Flight II Arleigh Burke-class destroyers. These ships have a five-inch gun, a 29-cell Mk 41 VLS forward, a 61-cell Mk 41 VLS aft, Mk 15 Phalanx Close-In Weapon Systems, and two quad Mk 141 launchers for the RGM-84 Harpoon anti-ship missile.
