Iran Fired Across the Bow of a U.S. Patrol Craft and Blocked the Strait Exit – The Mk 38 Answered… nt

At 3:17 AM on March 21, 2026, the Strait of Hormuz became the site of a high-stakes maritime confrontation that would test the resolve and tactical acumen of the U.S. Navy.

The USS Sarraco, a cyclone-class patrol craft, was attempting to exit the eastern end of the strait when an Iranian IRGC patrol boat fired a burst of 23 mm cannon fire directly across its bow.
The muzzle flash was visible to every sailor on the bridge, a clear indication that the Iranian vessel was asserting its presence in a bold and provocative manner.

As if to reinforce their intent, three additional Iranian boats accelerated to cut off the transit lane exit, effectively boxing the Sarraco into the strait.
