USS Asterion bow after collision with SS Kokoku Maru

1963  USS Asterion and SS Kokoku Maru collided in a heavy fog 40 miles west of San Francisco, killing one crewman of the latter ship and injuring three others. The Coast Guard cutters Magnolia, Comanche, Avoyel, and patrol boat CG-95311, as well as two commercial tugs, converged on the scene.  Comanche and Magnolia successfully removed all 43 survivors from the disabled Kokoku Maru, all of whom were subsequently delivered safely ashore. Although Asterion was able to proceed under its own power, the Japanese ship had to be towed by the commercial tugs to San Francisco.  When the bilge pumps on one of the tugs failed, Coast Guard aircraft dropped emergency pumping equipment to control the flooding.  The two tugs then successfully towed the Kokoku Maru into San Francisco harbor.

2023 CGC Dependable (WMEC 626) returned to its home port in Virginia Beach on Sunday, 4 June 2023, following a 42-day patrol in the Florida Straits and Windward Passage. Dependable’s crew contributed to the interdiction, care and repatriation of over 300 migrants while patrolling the Seventh Coast Guard District’s area of responsibility in support of Operation Vigilant Sentry and Homeland Security Taskforce — Southeast. While operating in the Florida Straits, Dependable was supported by multiple Coast Guard air assets to interdict two known drug smugglers in the vicinity of the Old Bahama Channel. Dependable’s small boat crew stopped the vessel and embarked the smugglers. Over 1,100 pounds of contraband was recovered, making this the first drug bust for the cutter in more than three years. Throughout the patrol, Dependable also collaborated with numerous other Coast Guard and partner assets, including a Coast Guard Law Enforcement Detachment embarked on the Navy ship USS Little Rock. “The crew has been training to conduct migrant interdiction operations since July 2022,” said LCDR Dana Prefer, Dependable’s executive officer. “In preparation for the recent uptick in maritime migration ventures, we worked hard to qualify over 50 crew members to provide security and care for the migrants embarked aboard the cutter. All the training and preparation paid off as it was truly a team effort to interdict, process, and care for the well-being of migrants throughout our patrol.”
