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.
This was not merely a harassment maneuver or a boarding attempt; it was a deliberate physical interdiction designed to trap the American naval vessel and force a confrontation on Iranian terms.
