Seaway7’s semi-submersible heavy-lift vessel Seaway Hawk is transporting four decommissioned U.S. Navy Avenger-class Mine Countermeasures ships—USS Devastator, USS Dextrous, USS Gladiator, and USS Sentry—to the United States.
According to a ship-tracking service, Seaway Hawk is currently sailing in East Africa and is scheduled to arrive in Philadelphia on 06 March 2026. The voyage involves the carriage of all four naval vessels as deck cargo on a single heavy marine transport operation.
Seaway Hawk ranks among the world’s five largest semi-submersible heavy-lift vessels. The vessel is purpose-built for transporting oversized and heavy offshore and onshore structures, supported by a large open deck and a high-capacity ballast system. This configuration enables routine transport of some of the world’s largest and heaviest drilling jack-up units.
The vessel offers a free deck length of 157 m and a free deck area of 8,700 m², providing substantial flexibility for complex multi-unit cargoes. Accommodation is available for up to 40 personnel. Seaway Hawk operates under IMO number 8616556.
Designed for float-on/float-off, skid-on/skid-off, roll-on/roll-off, and lift-on/lift-off operations, Seaway Hawk is widely deployed for heavy marine transport projects involving offshore facilities, large industrial structures, and naval assets.
