MCM Torch Passed in the Arabian Gulf (Again)
The four recently decommissioned 224-foot U.S. Navy Avenger-class Mine Countermeasures ships — the former USS Devastator, USS Dextrous, USS Gladiator, and USS Sentry — have departed Bahrain aboard the 65,000-ton Norwegian-flagged merchant heavy-lift vessel Seaway Hawk, marking their final voyage through the Arabian Gulf.
Seaway Hawk was escorted by USS Canberra (LCS 30), one of the three-pack of newly MCM-optimized Independence-class ships– the others being USS Santa Barbara (LCS 32) and Tulsa (LCS 16)-– that are currently forward-deployed to Bahrain, replacing the legacy Avenger-class ships that have served in Task Force 55 for over 30 years.
This isn’t the first time 5th Fleet MCM has passed the torch in the region with generational changes. Several circa-1950s wooden-hulled 120-foot Aggressive-class ocean minesweepers, including the USS Adroit (MSO-509) —subject of an upcoming Warship Wednesday —the USS Impervious (MSO-449), and the Leader (MSO-490), were deployed to the Persian Gulf beginning in 1990, notably supporting Operations Earnest Will, Desert Shield, and Desert Storm.
Before that, the old ‘phib USS Okinawa (LPH-3) had operated Navy RH-53D Sea Stallion minesweeping helicopters in the Gulf during Operation Ernest Will, and six small minesweeping boats (4 x 57-foot MSBs and 2x 36-foot MSLs) of Mine Group Two, Mine Division 125, had arrived in the region on USS St. Louis (LKA-116) and USS Raleigh (LPD-1) in the summer of 1987.

These brownwater boats were later augmented by the Aggressive class bluewater boats USS Fearless (MSO-442), Inflict (MSO-456), and Illusive (MSO-448), towed by USS Grapple (ARS-53) to the region. The epic nearly 10,000-mile journey began on 6 September 1987 and lasted roughly eight weeks, arriving in the Gulf of Oman on 2 November 1987. Upon arrival, the Inflict discovered and destroyed the first underwater contact mines in the northern Persian Gulf countered by an American minesweeper since the Korean War.
