Iranian Speedboats Rushed a US Destroyer at Close Range – The Navy’s Instant Response Left the Sea.. –

The USS Porter, an Arleigh Burke-class destroyer, is designed with a singular, formidable purpose: to engage threats at long range.

Equipped with advanced weaponry capable of targeting ballistic missiles from 200 miles away, aircraft from 100 miles, cruise missiles from 50 miles, and enemy ships from 80 miles, the destroyer’s operational philosophy hinges on one principle: detect early, engage far, and never allow threats to get close.

However, the Persian Gulf is not the open ocean; it resembles more of a crowded bathtub filled with islands, oil platforms, and busy shipping lanes.

This unique geography compresses engagement ranges, rendering the destroyer’s long-range capabilities nearly irrelevant.

On this fateful morning, nine Iranian speedboats emerged unexpectedly, closing in on the USS Porter from a mere 700 meters away—less than half a mile—with no warning, radar track, or time for anything other than instinctive reflexes.

As the USS Porter, DDG 78, patrolled the narrow waters between Iran’s Lavan Island and the contested Tonb Islands, the crew was on high alert.

The navigable channel was only about 12 nautical miles wide, and with the Iranian territorial claims and commercial shipping lanes, the effective operating space for the U.S. warship was reduced to a mere four nautical miles.

In this confined environment, the destroyer’s radar advantage was severely compromised.

At 0642 hours local time, the Porter was transiting eastbound at a standard patrol speed of 15 knots.

The bridge crew was fully manned, and all weapon systems were on standby.

The radar screen was cluttered with 14 commercial contacts, including fishing boats and tankers, creating a false sense of security.

However, at 0644, the ship’s electronic warfare system detected a brief encrypted communication burst emanating from the vicinity of Greater Tonb Island.

The technician assessed it as routine IRGCN communication, not suspecting the imminent threat.

Just three minutes later, at 0647, the lookout reported visual contacts: multiple small craft approaching dangerously close from the port beam.

The officer of the deck quickly estimated them to be about 700 meters away, running at high speed—at least 40 knots—and lacking any running lights.

The Iranian boats had cleverly concealed themselves among the commercial fishing vessels, blending in until they decided to accelerate and separate from the cluster.

Recognizing the imminent danger, the officer of the deck triggered general quarters, an alarm that reverberated throughout the vessel, alerting the crew to battle stations.

The captain arrived on the bridge within 28 seconds, quickly assessing the situation.

Nine fast boats were closing in, and they were now within the minimum engagement range for most of the ship’s primary systems.

At this close distance, the destroyer’s advanced missile systems became irrelevant; the weapons that mattered were the same that a World War II destroyer would have used—machine guns and the crew’s ability to aim and fire.

At 0648, the captain ordered weapons free, and without hesitation, the port’s .50 caliber machine gun opened fire first.

The gunner engaged the nearest boat, scoring direct hits to its engine, causing it to lose speed and come to a halt.

The Mark 38 chain gun followed suit, targeting the second boat and quickly destroying it.

The nine boats split into two groups, with five approaching tight along the port beam while four attempted to circle around the stern.

The port side boats found themselves in a deadly killing zone, as the crew unleashed a relentless barrage of fire.

As the starboard group completed their maneuver and opened fire with 12.7 mm machine guns, rounds impacted the destroyer’s aft superstructure, striking the helicopter hangar door and triggering a fault alarm that temporarily took the CIWS (Close-In Weapon System) offline.

This brief window of vulnerability coincided with the approach of four enemy boats, prompting the captain to call for the 5-inch gun to engage.

The fire control technician worked quickly to compute a manual targeting solution, bypassing the long-range calculations.

The gun fired at 0650, and the shell detonated on impact with the nearest starboard boat, resulting in a massive explosion that obliterated it and rocked the neighboring vessels.

At 0651, the CIWS came back online just in time to engage the last remaining starboard boat, which was at 250 meters and closing fast.

The 20 mm Vulcan cannon unleashed a devastating barrage, disintegrating the boat into fragments.

Within three and a half minutes of first contact, all nine Iranian boats were either destroyed, disabled, or sinking.

The crew conducted an immediate sweep of the area, launching the Seahawk helicopter to confirm no additional threats within a 10-nautical-mile radius.

The engagement, from visual contact to the last weapon fired, lasted a mere 3 minutes and 30 seconds.

However, the aftermath raised significant questions about how nine military fast boats managed to conceal themselves among civilian fishing vessels so close to a destroyer equipped with advanced radar systems.

An investigation revealed that the IRGCN had developed a tactic specifically tailored for the congested channel environment.

The boats had departed individually over four hours, blending into the fishing cluster’s radar returns and behaving like civilian vessels until they received the command to accelerate and attack.

This tactic exploited the limitations of surface search radar, which could identify a presence but could not distinguish between military and civilian vessels.

In response to the incident, the U.S. Navy implemented new protocols, assigning overhead drone coverage to provide visual identification of contacts classified as civilian.

The captain of the Porter was initially questioned about his decision to order weapons free without warning, but the review board ultimately deemed his actions justified given the imminent threat.

Iran’s response to the incident was notably silent—no media coverage, diplomatic protests, or complaints were made.

Internal communications indicated that the IRGCN command viewed the operation as a tactical failure, acknowledging that while the concealment tactic had worked, the cost was total loss.

All nine boats and their crews were lost, and the tactic was now compromised.

As the Porter resumed its routine operations, the incident served as a stark reminder of the dangers present in the Persian Gulf.

The number 700 meters became etched in the minds of every surface warfare officer in the region, representing the distance at which a $2.2 billion destroyer was forced to engage in close-quarters combat.

The chaos that unfolded in under four minutes highlighted the need for vigilance and adaptability in modern naval warfare.

The crew’s swift and aggressive response saved the Porter from potentially catastrophic consequences, but the next encounter may not afford them the same luck.

The evolving nature of tactics and the unpredictability of adversaries necessitate constant readiness and innovation.
