Iranian Missiles Closed In – Third Locked on U.S. Destroyer

The tension in the Gulf escalated dramatically as Iranian missiles closed in on an American convoy, a situation that was anything but accidental.

It was a calculated maneuver, designed to create a formidable barrier.

The splash pattern of the gunfire was meticulously crafted to land directly across the convoy’s intended course, forming a wall of water and foam between the American ships and their route.

In the previous 22 minutes, three Iranian surface combatants had strategically moved into blocking positions.

No one aboard the American convoy anticipated that they would actually fire.

The convoy in question was not a formidable warship formation; it consisted of three essential vessels: a combat store ship, a dry cargo and ammunition ship, and a fleet oiler.

These ships represent the logistical backbone that sustains American naval operations in the Gulf.

Without regular replenishment convoys, the destroyers, cruisers, and carriers projecting American power in the region would run dry within days.

Logistics convoys may not be glamorous, but they are as vital to naval power as any combatant vessel.

The eight-month pattern of these operations had rendered the convoy vulnerable.

Operational planners had ᴀssessed the central Gulf corridor as a low-threat zone, primarily due to the absence of previous incidents.

Such low threat ᴀssessments directly influenced escort decisions, which in turn shaped the convoy’s vulnerability to potential attacks.

The Iranian surface action group had staged from Bandar Abbas over the preceding 48 hours, comprising the Mauge-class frigate Damavand, weighing in at 1,500 tons, armed with a 76 mm main gun and C802 anti-ship missiles, along with two Cenaclass fast attack craft, each equipped with guns and rocket systems.

The three vessels conducted what Iranian naval records would later characterize as a scheduled patrol exercise.

American surveillance had logged their departure from Bandar Abbas and categorized their activity as a routine patrol, with no indication of intent to interdict.

This ᴀssessment was based on what the ships were doing rather than where they were headed.

By 6:40, the Iranian surface group had positioned itself across the convoy’s projected track—not behind or parallel to it, but directly ahead in a blocking formation that would force the convoy to either stop, significantly change course, or push through.

At 6:47, the USS McFall’s surface radar detected the three Iranian contacts, which were stationary and directly in the convoy’s path.

The officer of the deck promptly reported this to the captain, who arrived on the bridge at 6:49 and noted the unusual situation: three military vessels lined up directly across the convoy’s track, approximately 11 nautical miles ahead, waiting and unmoving.

At 6:51, the captain transmitted a message on channel 16, identifying the McFall and the convoy, stating their course and destination, and requesting the Iranian vessels to clear the route.

This transmission was made in both English and Farsi, following the dual-language protocol routinely used by American naval forces in the Gulf, but there was no response from the Iranian formation.

At 6:54, the convoy slowed to a minimum steerage speed, as the lead replenishment vessel, carrying 7,200 tons of aviation fuel, dry cargo, and ammunition, could not maneuver as quickly as a warship.

The captain of the McFall was faced with two conflicting obligations: maintain the escort of the convoy while positioning the McFall to respond to the blocking force ahead.

At 7:02, the two Cenaclass fast attack craft began to move, separating from the central frigate and accelerating to flank positions—one moving to the convoy’s projected starboard side and the other to port.

This maneuver took seven minutes, placing both fast attack craft approximately three nautical miles on either side of the convoy’s projected track.

The convoy was being channeled, with the frigate blocking ahead and the fast attack craft covering the flanks, creating a three-point containment strategy.

At 7:08, the McFall’s commanding officer transmitted a second warning on channel 16, explicitly stating that the blocking maneuver consтιтuted interference with lawful navigation in international waters and that the United States Navy would take appropriate action to ensure the convoy’s safe pᴀssage.

At 7:09:14, the Damavand fired its 76 mm gun, sending two rounds forward of the convoy’s bow, approximately 400 meters away.

The splashes were visible from the bridge of the lead replenishment vessel, where a crew not trained for combat operations was confronted with the reality of naval gunfire just ahead.

The rules of engagement authorized returning fire on the Damavand, given the demonstrated hostile fire, which would mean engaging the Iranian naval combatant with anti-ship missiles or the 5-inch deck gun.

However, destroying or disabling an Iranian frigate in the central Gulf would consтιтute an act of war, and the authorization chain for that decision extended above CENTCOM to the Secretary of Defense and potentially to the president.

The destroyer captain transmitted a flash precedence message to CENTCOM at 7:09, just 34 seconds after the Iranian gun fired.

However, CENTCOM’s response took seven minutes.

In those seven minutes, the convoy had come to a near stop, and the captain of the lead replenishment vessel had ordered all non-essential personnel below decks, with the engineering team monitoring the engines at maximum readiness for emergency maneuvers.

The crew of a ship that had never expected to be in a combat situation was now positioned just 11 nautical miles from a formation that had just fired its main gun in their direction.

The McFall maneuvered to position itself between the convoy and the Damavand, closing to approximately seven nautical miles from the Iranian frigate.

At that range, the McFall’s Harpoon anti-ship missiles, with a range of approximately 67 nautical miles, were well within engagement parameters, and the crew prepared a targeting solution.

However, the captain did not yet have authorization to execute.

At 7:14, two FA-18F Super Hornets from the USS Dwight D. Eisenhower, which had been conducting air operations approximately 160 nautical miles to the southeast in the Gulf of Oman, crossed into the central Gulf airspace at 18,000 feet on an intercept course for the Iranian surface group, with an estimated arrival time of approximately nine minutes.

At 7:18, the FA-18s were just four nautical miles from the Iranian formation, descending through 8,000 feet.

Both aircraft had their A/A PG73 radars in active mode, and the Iranian ships could see themselves being painted by American fire control radar.

The Super Hornets were armed with AGM-84 Harpoon missiles on their wing stations and AIM-120 AMRAAM for self-protection, and this loadout was visible in the radar cross-section and in the electronic emissions that the Iranian ships’ own electronic warfare systems were detecting.

At 7:19, the Damavand’s radar shifted from active search to fire control mode, acquiring one of the FA-18s.

This moment marked a critical decision point.

An Iranian frigate had fired on an American convoy, and now its fire control radar was targeting an American aircraft.

Under the rules of engagement governing the FA-18 crews, an active fire control radar lock consтιтuted a hostile act, authorizing an immediate response.

The flight lead, call sign Viper 1, broadcast on the guard frequency at 7:19:22, warning the Iranian warship that it was illuminating U.S. Navy aircraft with fire control radar and instructed them to cease immediately or face self-defense measures.

The Damavand’s fire control radar was turned off at 7:19:41, just 19 seconds after the warning.

What transpired in those 19 seconds aboard the Damavand remains uncertain.

The decision to deactivate the fire control radar and back down from the lock was likely made by the Iranian frigate’s commanding officer or possibly the surface group commander.

Someone on the Iranian side calculated that the tactical situation had changed, with two Super Hornets overhead, the McFall positioned with a targeting solution, and flash traffic moving through American command channels.

The picture had shifted from an isolated convoy interdiction to a potential multi-domain engagement involving American air and surface forces.

At 7:23, the Damavand began moving eastward back toward the Iranian coastline instead of toward the convoy, followed within four minutes by the two Cenaclass fast attack craft.

The blocking formation dissolved, and the McFall transmitted on channel 16 at 7:24, indicating that the convoy was resuming transit and increasing speed.

The replenishment vessels began moving forward on their original track, while the FA-18s remained on station, circling at 15,000 feet for the next 47 minutes until the convoy cleared the area.

The Damavand and its escort were tracked by both the McFall’s radar and the Super Hornet sensors until they were confirmed to be returning to Bandar Abbas.

The convoy completed its delivery mission and reached the fleet oiler rendezvous point without further incident.

Now, let’s analyze what this incident revealed about Iranian convoy interdiction doctrine and why the attempt was made in the first place.

The central Gulf corridor carries American logistical traffic that sustains the entire naval presence in the region.

Iranian military planners possess considerable insight, honed through years of surveillance and pattern analysis, regarding the rhythm of American replenishment operations.

They understand the approximate frequency of convoy transits and the typical composition, which usually involves one or two combatant escorts for three to four replenishment vessels.

Moreover, they know that the escort doctrine for logistics convoys is less robust than that for combatant formations.

The blocking operation was designed to test whether American convoy doctrine could be disrupted by a surface interdiction that stopped short of outright sinking, applying enough coercive pressure through positioning and warning fire to force the convoy to either change course or request additional forces, thereby diverting ᴀssets from other operational areas.

Neither outcome necessitated the destruction of an American ship, yet both imposed costs on American operations.

The tactic exploited a genuine decision-making gap.

The McFall’s captain had clear authority to defend the convoy from an attack but had less clear authority to engage an Iranian surface combatant based on blocking maneuvers and warning fire that had not yet directly struck an American vessel.

The legal and operational gap between being fired at and fired near is significant.

Iranian planners understood this gap and calibrated their actions to remain within it for as long as possible.

The 76 mm gunfire was the element that closed this gap.

Once the Damavand fired rounds across the convoy’s bow, the authorization for defensive action was triggered.

However, the seven-minute delay between the sH๏τ and CENTCOM’s response, even if operationally appropriate, illustrated that the authorization chain for engaging Iranian naval combatants is not designed for the rapid pace of incidents that can escalate within minutes.

The post-incident review at CENTCOM led to two operational modifications.

First, the convoy escort doctrine for the central Gulf corridor was upgraded.

Single destroyer escorts for replenishment convoys were replaced with a minimum of two combatants, along with a defined standby air support protocol that ensured fighters were on deck alert at the carrier rather than airborne.

This adjustment could reduce response time from nine minutes to approximately four minutes from alert to overhead.

The second modification was doctrinal.

CENTCOM established pre-delegated authority for convoy escort commanders to respond to demonstrated hostile fire from Iranian naval combatants without waiting for higher authorization, provided that the response was proportionate and limited to neutralizing the specific threat.

The seven-minute gap during which the convoy was halted, and crew members sheltered below decks while an Iranian frigate’s fire control radar tracked American aircraft, was deemed an unacceptable decision latency in a fast-moving engagement.

The Damavand returned to Bandar Abbas that afternoon, and Iranian state media made no mention of the incident.

No official statement was issued by the Iranian Navy or the IRGCN.

The crew of the lead replenishment vessel, comprising a mixed team of civilian mariners and navy personnel not trained for combat, submitted a collective after-action account that was reviewed at the fleet level.

The account was clinical in its description of events and measured in its emotional register.

However, one crew member noted that he had watched the water columns from the Iranian gun rise and fall through the bridge windows, not knowing for approximately four minutes whether the next sH๏τ would hit the ship.

This detail was incorporated into the psychological support briefings that Navsense subsequently developed for non-combatant crew members operating in contested Gulf environments.

The FA-18 flight lead, Viper 1, landed back aboard the Eisenhower at 09:14, with a debrief lasting two hours.

The 19-second window between his warning transmission and the Damavand’s fire control radar deactivation was analyzed in detail, particularly the question of at what point, had the radar remained active, he would have fired.

His answer, documented but not made public, remains a critical piece of the puzzle.

In the central Gulf, replenishment convoys continue to operate, following the same route.

The Iranian Navy remains active, patrolling and calculating their next moves.

The escorts are now stronger, air cover protocols are тιԍнтer, and the authorization chain is shorter, but the Damavand class frigate is still commissioned, and its 76 mm gun remains operational.

Somewhere in the Iranian naval operational planning cycle, the convoy interdiction scenario is still on the table, modified and updated based on what worked and what didn’t during that fateful morning when the Super Hornets arrived.

The next patrol might not wait nine minutes before something worse than warning fire crosses the water.
