September 25, 2025 seems like forever ago. The U.S. Navy held a ceremony at Naval Support Activity Bahrain to decommission USS Devastator, the last of four Avenger-class minesweepers that had operated in the Persian Gulf for 35 years. Vice Admiral George Wikoff, then commander of U.S. Naval Forces Central Command spoke fondly of the technological defense achievement:

They are “true trailblazers” who had defended freedom of navigation and deterred efforts “by adversaries to harm the innocent.”

On January 9, 2026, the four decommissioned hulls — Devastator, Dextrous, Gladiator, and Sentry — were physically loaded onto a contracted heavy-lift vessel, the M/V Seaway Hawk, and removed from Bahrain. They are slated for dismantlement.

A little over a month later, defenses gone, on February 28 the United States and Israel launched Operation Epic Fury against Iran. And it goes without saying that Iran’s primary asymmetric response is mining the Strait of Hormuz.

Mind the Gap

That sequence of self-inflicted weakness is documented. For some reason the connection is not being made into headlines.

Stars and Stripes covered the September ceremony. USNI News covered it the same day. The War Zone covered the January physical departure and noted, only in passing:

the continued critical importance of naval mine-clearing capacity in the Middle East is underscored now by a new surge in geopolitical friction between the United States and Iran.

Naval News ran the best report so far: the replacement Independence-class littoral combat ships:

have struggled to meet the requirements of operational mine countermeasures missions.

Struggled.

CNBC mentioned the decommissioning in two sentences buried inside a March 11 piece on the mine strikes.

No major outlet has run the timeline as a single story about the administration removing the directly applicable dedicated mine-clearing force, while it started the war where mines are the threat.

Avengers in Brief

The Avengers were purpose-built for this exact mission. Wooden hulls were sheathed in fiberglass, using oak, Douglas fir, and Alaskan cedar chosen specifically to minimize magnetic signature and reduce vulnerability to the magnetic-influence mines Iran stockpiles.

At 68 meters and 1,312 tons, they were small enough to operate close to mined areas. They carried sonar, video systems, cable cutters, and remotely detonated mine-disposal devices.

The Navy built 14 of them between 1987 and 1994. The four at Bahrain had been forward-deployed since 2012. At the decommissioning ceremony, Lt. Commander Alex Turner told his sailors to take home their piece of Douglas fir plank and remember what they carried with it.

The ships are well on their way to Philadelphia for disposal, if not already gone.

What Has Come Since

The Independence-class LCS is an aluminum trimaran built by Austal USA. It is significantly larger than the Avengers. The War Zone noted at the time of departure a significant size difference:

…could impose limits on how close they can get to mined or potentially mined areas.

The ships are metal-hulled, which is the exact opposite design choice from the superior design of wooden Avengers. And the mine countermeasures mission package for these ships was not even installed until 2025. USS Canberra received it in April 2024 and arrived in Bahrain in May 2025. USS Santa Barbara and USS Tulsa followed. The program had been delayed by more than a decade of failed systems, equipment failures, and integration problems. Naval News documented the specifics at the time of the Avenger retirement: during one test of the MCM package on USS Tulsa, a tow bracket broke, leaving an unmanned surface vehicle unrecoverable and requiring another ship to retrieve it. The sensors in the current suite are ineffective in turbid or deep water. Pre-mission preparation takes approximately six hours. Any single equipment failure in the design renders the entire thing inoperable: the platform lift, the tow hook, the crane frame for deploying unmanned vehicles.

The Navy and Pentagon labeled this transition unenthusiastically, as if it was boredom with what works driving the mistakes:

…a much needed step towards modernizing the fleet.

Needed. Much needed.

The current situation

CNN reported March 10 that Iran has begun laying mines in the strait, already a few dozen. According to U.S. intelligence, Iran still retains 80 to 90 percent of its small boats and mine-layers, and could feasibly deploy hundreds more. CBS News reported that while Iran’s total mine stockpile is not publicly known, estimates over the years have ranged from 2,000 to 6,000 naval mines of Iranian, Chinese, and Russian manufacture.

Reuters reported the same day that the U.S. Navy has refused near-daily requests from the shipping industry for military escorts through the strait since the start of the war, telling industry briefings the risk of attacks is too high.

Three shipping industry sources confirmed the Navy’s position has not changed regardless of Trump propaganda: escorts will only be possible once the risk of attack is reduced. A maritime security source told Reuters that securing the strait could require taking control of Iran’s vast coastline.

There are not enough naval vessels to do that and the risks remain high even with an escort. One or two vessels can be overwhelmed by a swarm.

Trump has said repeatedly that the United States is prepared to escort tankers through the strait whenever needed. On March 10, Energy Secretary Chris Wright posted on X that the Navy had successfully escorted an oil tanker through Hormuz. He deleted the post within 30 minutes. White House Press Secretary Karoline Leavitt told reporters shortly after:

I can confirm that the US Navy has not escorted a tanker or a vessel at this time.

On the same day, Trump posted on Truth Social that if Iran had put mines in the strait — “and we have no reports of them doing so” — he wanted them removed immediately or Iran would face military consequences “at a level never before seen.” U.S. Central Command then announced it had destroyed only 16 Iranian mine-laying vessels.

Avengers Deactivated

The Avengers were the tool for this specific problem. They existed for exactly this threat environment in the Persian Gulf for Iranian mines, and close-in clearance work. They had 35 years of operational history in the region. The decision to remove them was made just before the mindless run-up to go to war, as if the two Middle-East war fighting capability calendars are unrelated.

The LCS replacement had not demonstrated operational mine countermeasures capability before it was pressed into service as the justification for retiring the Avengers. How could they, given MCM package’s first two operational installs happened in 2025? The Avengers were ripped out by January 2026, while Trump unilaterally rushed into a mine war February 28.

Mindless.

Trump is now threatening Iran with real estate developer language of “never before seen” consequences, as he always does to everyone for everything. But the real calculus is that Iran very, very predictably is mining the strait that Trump just removed his own capacity to clear.
