U.S. Navy independent USS-class Littoral Combat Ship (LCS) Tulsa and the U.S. Navy santa barbaraOnes configured for mine clearance duties have appeared in Malaysian ports. It is understood that the two ships were last deployed in the Middle East, arriving in Bahrain in the past year or so, replacing a group of now-decommissioned ships. the Avengers Mine hunter-like. Now, the ships have emerged thousands of miles away as Iranian attacks on merchant ships have brought maritime traffic to a virtual halt in the highly strategic Strait of Hormuz. The extent to which Iran has mined the strait is unclear, but it still poses a significant threat to the future security of the waterway, which must be taken into account in any future efforts to reopen this vital waterway.

Interesting. The littoral combat ships USS Tulsa and USS Santa Barbara, which were rotated to the Middle East and were supposed to serve as the U.S. Navy’s mine countermeasures platforms in the region, are now anchored in Penang, Malaysia. @limzeruihttps://t.co/Fe0r7VizQm
March 15 – Two U.S. Navy littoral combat ships (LCS) sent to the Persian Gulf to perform mine countermeasures (MSM) missions are currently docked in Butterworth, Malaysia.

U.S. Navy Tulsa and the U.S. Navy santa barbara are in selected some independent Littoral combat ships equipped with mine countermeasures mission packages or “modules.” Current options include towed mine detection sonar for ships, common unmanned surface vehicles (CUSV) with minesweeping gear, and mine detection and suppression systems carried by ship-based MH-60 Seahawk helicopters. We will return to this configuration later.
When it comes to why these ships are now anchored in Malaysia, TWZ We also contacted U.S. Central Command (CENTCOM), who directed us to contact the U.S. Navy’s 5th Fleet. We then returned to Central Command under the command of Fifth Fleet. Central Command is the highest military command agency of the United States responsible for operations in the Middle East. The Fifth Fleet is the Navy’s numbered fleet in the Middle East, and its commander is also the commander of Naval Forces Central Command (NAVCENT). Fifth Fleet and Naval Central Command are headquartered in Manama, Bahrain, on the Persian Gulf.
We also contacted the U.S. Navy and U.S. Indo-Pacific Command (INDOPACOM).

Separate images also show the USS santa barbara Operating in the Persian Gulf on January 30. Currently the third ship independent LCS class, USS CanberraIt was unclear whether the force was forward-deployed in the Middle East as of at least January. It is also unknown whether there are other mine countermeasures ships that may not be heading to the Middle East.

A review of satellite images in Planet Labs’ business archives shows there is no evidence of any U.S. warships docked at the Mamana port since February 23. The United States and Israel launched a joint operation against Iran on February 28.
Moving U.S. warships out of Bahrain ports ahead of the current conflict is a prudent security measure. The Gulf state was well within range of Iranian missiles and long-range kamikaze drones, and U.S. military installations in Manama were subsequently attacked. The U.S. attack on an Iranian naval vessel in the port highlighted the vulnerability of ships moored at the docks.
Why the decision was made to subsequently send the U.S. Navy Tulsa and the U.S. Navy santa barbara Thousands of miles to the east, no one knows. A number of factors may come into play, including the availability of suitable friendly ports and diplomatic considerations.
In any case, at least two-thirds of the warships intended to conduct mine countermeasures missions in the Middle East are currently located in completely different parts of the world. As mentioned earlier, the U.S. Navy TulsaU.S. Navy santa barbaraand the U.S. Navy Canberrafirst explicitly forward-deployed to the region to fill the void left by the four retired aircraft the Avengers Last year’s mine hunter class.

How many people are there in the navy? independent class To date, the total number of LCS configured for the minesweeping mission is unknown. Except for the U.S. Navy TulsaU.S. Navy santa barbaraand the U.S. Navy CanberraU.S. Navy kansas city As of last year, at least this mission module was equipped.
this independent The LCS class is a much more advanced ship than the Littoral Combat Ship the Avengers level mine hunter, and does provide new standoff mine countermeasures capabilities, including the aforementioned CUSV unmanned boat and helicopter airborne systems. Still, questions remain about whether a metal-hulled LCS with a mine countermeasures suite is an adequate replacement for ships built specifically for the mission. as TWZ Previously replied in January:
this [Avenger class] The ship itself has a fiberglass-coated wooden hull to reduce its own vulnerability, particularly to mines that detect targets via magnetic signatures.
The U.S. Navy has long intended to replace the Avenger-class ships with littoral combat ships configured for mine countermeasures missions. However, delays with LCS mine countermeasures and other mission packages, or “modules,” as well as other ongoing issues with both subclasses of these ships, have repeatedly delayed those plans. The Littoral Combat Ship program also originally envisioned the ship being easily reconfigured to suit different mission sets by swapping out modules. However, the Navy is currently fielding LCSs in a largely fixed configuration.
…
Questions and criticism have arisen in the past regarding the suitability of metal-hulled LCSs for mine countermeasures missions. Both subclasses of LCS are also much larger than the Avenger-class design, which may limit their distance from minefields or potential minefields. Littoral combat ships are better able to defend against other threats than the Avengers, but their firepower is still relatively limited, which has been another source of criticism over the years. Level III support is still needed to protect the LCS during mine clearance operations, which are slow and complex and pose significant risks even in benign environments.

According to a report published just last week, in May 2025, a senior U.S. Navy mine warfare officer issued an unclassified briefing detailing significant ongoing issues with Littoral Combat Ship mine countermeasures. hunterbrook media. A copy of the briefing slides released by the outlet said using CUSV requires hours of preparation and the drone ship’s sonar sometimes struggles to detect threats, but operators may not have any indication until the data is evaluated after the mission. Visual identification of mines using the AN/AQS-20 mine detection system also proved challenging, “even [in] Relatively mild turbidity in Southern California [Southern California] Another slide explained. The briefing also highlighted some potential “single points of failure” in terms of the mine countermeasures systems included in the module and the equipment required to deploy and recover these systems.

Finally, and perhaps most importantly, one of the briefing slides noted that “the LCS is designed to be a multi-mission platform” and that “all of these other missions reduce the time for the ship and minelayers to become proficient in MCM.” [mine countermeasures]”. To reiterate, the Avengers This class of ships is purpose-built for this mission and has a highly trained crew to match it. Mine clearance operations are slow and complex, and carry significant risks even when conducted by experienced personnel in good conditions.
In the context of the current conflict, there have been reports over the past week or so that Iran is at least trying to lay mines in and around the Strait of Hormuz. The U.S. military also said it has been actively targeting mine-laying assets. At the same time, Iran’s past history of laying mines in and around the Persian Gulf remains a real concern. Iran’s anti-ship cruise and ballistic missiles, kamikaze drones and explosives-laden unmanned vessels further complicate the threat to commercial ships and any warships trying to help clear the way.

As things stand, U.S. warships are unlikely to begin escorting commercial ships through the Strait of Hormuz for at least several weeks, U.S. officials said. Convoy operations are inherently risky and require significant maritime and other domain support assets, e.g. TWZ This has been explained before. The limited availability of mine countermeasures assets will create additional challenges.
It remains to be seen how long the U.S. Navy can hold out Tulsa and the U.S. Navy santa barbara will remain in Malaysia and wherever they may sail after their departure. where is the us navy Canberra It remains unknown whether any additional mine countermeasures-equipped ships are en route to the Middle East.
At least for now, in the event of a major conflict with an adversary that has experienced mine warfare, a significant portion of the Navy’s minesweeping capabilities in the region are now thousands of miles away in an entirely different part of the world.
