U.S. Navy Minesweepers Assigned To Middle East Have Been Moved To Pacific (Updated)
2026-03-17
[TWZ] The U.S. Navy Independence class Littoral Combat Ships (LCS) USS Tulsa and USS Santa Barbara, which are configured for minesweeping duties, have appeared in port in Malaysia. Both of these ships were last known to be forward-deployed in the Middle East, having arrived in Bahrain in the past year or so to take the place of a group of now-decommissioned Avenger class mine hunters. Now, as Iranian attacks on commercial ships have caused a virtual halt to maritime traffic through the highly strategic Strait of Hormuz, these ships have emerged thousands of miles away. The extent to which Iran has seeded naval mines in the Strait already is unclear, but this remains a huge threat to the future security of the waterway and will have to be taken into account in any future effort to reopen this critical waterway.

A spotter in Malaysia posted pictures of the USS Tulsa and USS Santa Barbara, which are said to have been taken today at the North Butterworth Container Terminal (NBCT) in the Port of Penang. Mike Yeo, an Australia-based defense and aviation reporter, was among the first to call attention to the particular significance of the images. TWZ has reached out for more information.

USS Tulsa and USS Santa Barbara are among a select number of Independence class LCSs fitted with a mine countermeasures mission package, or “module.” In its current form, the package includes towed mine-hunting sonar for the ships, Common Unmanned Surface Vehicles (CUSV) with mine-sweeping gear, and mine detection and neutralization systems carried by embarked MH-60 Sea Hawk helicopters. We will come back to this configuration later on.

A review of satellite imagery in Planet Labs’ commercial archive shows no evidence of any U.S. warships being in port in Manama since February 23. The United States and Israel launched their joint operation against Iran on February 28.

Moving U.S. warships out of port in Bahrain ahead of the current conflict was a prudent security measure. The Gulf state is well within range of Iranian missiles and long-range kamikaze drones, and U.S. military facilities in Manama did subsequently come under attack. The U.S. military’s own strikes on Iranian naval vessels in port have underscored the vulnerability of ships sitting pierside.

Why the decision was made to then send the USS Tulsa and USS Santa Barbara thousands of miles to the east is unknown. A host of factors may have come into play, including the availability of suitable friendly ports and diplomatic considerations.

Regardless, at least two-thirds of the warships intended to be available for tasking for mine countermeasures missions in the Middle East are presently in a completely different part of the world. As noted, USS Tulsa, USS Santa Barbara, and USS Canberra, were forward-deployed to the region in the first place explicitly to fill gaps left by the decommissioning of four Avenger class mine hunters last year. The former USS Devastator, USS Dextrous, USS Gladiator, and USS Sentry left the region for good aboard a heavy lift ship in January. There are only four Avenger class ships left in active Navy service, all of which are forward-deployed in Japan, and are also slated to be decommissioned in the coming years.

How many of the Navy’s Independence class LCSs, in total, have been configured for the mine-clearing mission to date is unknown. In addition to USS Tulsa, USS Santa Barbara, and the USS Canberra, the USS Kansas City was at least being fitted out with this mission module as of last year.

The Independence class LCS is a far more advanced ship than the Avenger class mine hunter, and does offer new standoff mine countermeasures capabilities, including aforementioned CUSV drone boats and helicopter-borne systems. Still, questions continue to be raised about whether metal-hulled LCSs with mine countermeasures packages are adequate replacements for ships purpose-built for this mission.
A bunch of no-doubt intelligible paragraphs about something terribly naval snipped, dear Reader, allowing us to reach the denouement:
UPDATE: 3/16/2026 —

U.S. Navy Commander Joe Hontz, a spokesperson for NAVCENT, has provided TWZ with the following statement:

“Tulsa and Santa Barbara are conducting brief logistical stops in Malaysia. U.S. forces routinely make port calls in Malaysia as part of our operations, reflecting the close and enduring military cooperation between the United States and Malaysia.”
