20 April

1871  The Secretary of the Treasury was authorized by Congress to employ crews of experienced surfmen at lifeboat stations at maximum rate of $40 per month, marking the end of the volunteer system.  This was the beginning of direct Federal control over life-saving activities.

2010  The Deepwater Horizon oil rig located more than 50 miles southeast of Venice, Louisiana, suffered massive explosions killing 11 and injuring 16 of its 126 person crew. The oil platform, which burned for more than a day, sank into the Gulf of Mexico on April 22, 2010.  An estimated 60,000 barrels of oil gushed each day for 87 days, making the Deepwater Horizon spill and its response unprecedented.  The Coast Guard mobilized 14% of its total workforce, active duty and reserve, and its role expanded under the National Contingency Plan which called for the service to direct all response efforts to contain and clean up the oil spill. On April 30th, 2010 Admiral Thad Allen, the Coast Guard Commandant, was appointed as the National Incident Commander (NIC) to oversee the federal response.  He retired as Commandant on May 25, 2010, but continued on as NIC in uniform until he formally retired from the Coast Guard on June 30, 2010.  He then continued to serve as NIC (as an SES civilian) until October 1, 2010.

April 19

1995  A rental truck filled with explosives blew up half of the Murrah Federal Building in Oklahoma City, Oklahoma.  Coast Guardsmen from the Coast Guard Institute and a Coast Guard reservist responded soon after the explosion and helped set up security zones, directed traffic, searched for survivors, and whatever else was needed.  They also took over a church kitchen and opened what later became nicknamed “Cafe Coast Guard.”  A rotating nine-person team worked around the clock to provide meals for the volunteer workers.

2014  Coast Guard marine inspectors conducted safety and security examinations on the first-ever container ship to arrive in Cleveland. The Fortunagracht, a 450-foot Dutch-flagged container ship, delivered the first-ever load of containerized cargo to the Great Lakes.  Before the establishment of the Cleveland-Europe Express, shippers relied heavily on rail service to transport goods from the larger east coast container ports, such as New York and Baltimore, to the Great Lakes region.  Talks to bring CEE to Cleveland began in the fall of 2013 with cooperation between the Coast Guard, Customs and Border Protection, the FBI, and other government agencies.

USRC Louisiana

1805  The cutter Louisiana recaptured the merchant brig Felicity from privateers off the mouth of the Mississippi River.

1945  Airship training for U.S. Coast Guard personnel (nine officers & 30 enlisted men) began at Naval Air Station Lakehurst, New Jersey.

1993  Coast Guardsman Gary A. Openshaw rescued five persons in danger of drowning near San Francisco off Baker Beach.  For heroically risking his life and saving those five people, the Coast Guard awarded Petty Officer Openshaw the Gold Life-Saving Medal.

USRC Louisiana

1805  The cutter Louisiana engaged two pirate vessels that had been fitted out at New Orleans.  Twenty shots were exchanged but the pirate vessels escaped.

1851  The Minot’s Ledge Lighthouse, the first one built in the United States that was exposed to the full force of the ocean, was swept away by a storm with the loss of the two men manning it.  They were Assistant Keepers Joseph Wilson and Joseph Antoine who maintained their station, ringing the lighthouse’s bell, until waves swept the tower away.

USCGC Spencer (WPG-36) in 1942 or 1943. Spencer sank U-175 with assistance of USCGC Duane, on April 17, 1943.

1943  Lieutenant Ross P. Bullard and Boatswain’s Mate First Class C. S. “Mike” Hall boarded the U-175 at sea after their cutter, CGC Spencer, blasted the U-boat to the surface with depth charges when it attempted to attack the convoy Spencer was escorting.  These Coast Guardsmen were part of a specially trained boarding party sent to board the submarine to seize any code and cipher related documents and equipment they could find.  The damage to the U-boat was severe, however, and it sank after they had boarded it and climbed up the conning tower.  Both men ended up in the sea as the U-boat slipped beneath the waves but were pulled from the water unharmed.  They carry the distinction of being the first American servicemen to board an enemy warship underway at sea since the War of 1812.  The Navy credited Spencer with the U-boat kill.  The cutter rescued 19 of the U-boat’s crew and a sister cutter, CGC Duane, rescued 22.  One Spencer crewman, RM 3/c Julius Petrella, was killed by friendly fire during the battle.

1987  LT Tom McClay received a direct commission as a flight officer for duty with the Coast Guard’s E2C Hawkeyes.  LT McClay was the first Coast Guard flight officer.

USCGC Steadfast (WMEC 623)

2020  The crew of the Coast Guard Cutter Steadfast (WMEC 623) returned home 17 April 2020 to Astoria following a 65-day counternarcotic patrol to the Eastern Pacific Ocean. The cutter intercepted and boarded five suspected smuggling vessels, including one go-fast-style panga, while patrolling international waters off the coasts of Mexico and Central America.  Steadfast’s crew apprehended three suspected smugglers and seized 1,252 pounds of pure cocaine worth an estimated $21.5 million. “I am inspired daily by the tenacity and professionalism of this crew,” said Cmdr. Dan Ursino, commanding officer of the Steadfast. “Their resilience to remain focused, in light of the global health crisis and uncertainty back home, has been nothing short of remarkable.  Knowing the importance and impact of keeping these harmful substances from reaching our streets help to keep us going.” Steadfast also continued to participate in the Columbia River Maritime Museum’s Mini Boat Project, which connected students from local Oregon elementary schools with their peers in Japan. Students learned about the significance of ocean currents and weather, while building miniature boats to send across the ocean to one another.  During this patrol, Steadfast launched two boats, Boat-A-Lohti and Philbert, approximately 200 miles off the southern tip of Baja, Mexico.

Location: PORT VALDEZ, ALASKA (AK) UNITED STATES OF AMERICA (USA)

Below is a Coast Guard news release.

The last three US Coast Guard 110 foot Island class WPBs were in Alaska. Mustang in Seward, Naushon in Homer, and Liberty in Valdez. Naushon was decommissioned March 21st. With Mustang decommissioned April 15, Liberty is the last of 49 Island class cutters that have seen service with the Coast Guard.

Like the Hamilton class cutters, a number of the class are still in service with other navies and coast guards, in Costa Rica, Georgia, Greece, Pakistan, and Ukraine. At least one, the former USCGC Cushing, was sunk while in Ukrainian service.

gCaptain reports,

The U.S. Coast Guard’s Homeport portal, a critical online platform for maritime operations since 2005, was permanently taken offline on April 12, 2025, leaving the maritime industry scrambling to adapt to alternative credentialing and verification processes.

The shutdown follows a unplanned period of restricted access that began on March 4, 2025, causing significant disruptions across the maritime sector and preventing employers from verifying crew credentials. gCaptain is told the HOMEPORT system’s inaccessibility has already resulted in job losses for mariners who cannot verify their credentials through the previously available online tools.

From the Homeport page,

The Coast Guard Homeport Internet Portal platform will be decommissioned on 12 April 2025. You will need to use alternate approaches for tasks typically performed through the Homeport platform.

We recognize that Homeport has long been a trusted tool for mariners and the broader maritime community. The Coast Guard is establishing temporary workarounds to ensure essential services remain accessible until we can identify the best permanent approach for each function.

The following pages will provide you with guidance on how to conduct activities previously done through Homeport.

The Coast Guard is responsible for maintaining both the physical and cyber security of our country’s maritime commerce system. The Homeport system is facing increasing costs and system obsolescence. As a result, it is no longer a viable tool for managing the many functions required to ensure the smooth and safe flow of vessel traffic.

250407-N-OC941-4089 NAVAL STATION MAYPORT, Florida – (Apr. 7, 2025) – Led by Rear Adm. Carlos Sardiello, Commander U.S. Naval Forces Southern Command/U.S. 4th Fleet, more than 100 Sailors, Marines, and civilians gathered onboard Naval Station Mayport in support of the UNITAS 2025 Mid-Planning Conference. This year’s UNITAS, scheduled for September, is the longest-running, multinational maritime exercise in the world. UNITAS 2025 will combine the efforts of Allies and Partners from across the globe and serve as the warfighting introduction to Navy 250 – the U.S. Navy’s year-long birthday celebration. U.S. Naval Forces Southern Southern Command and the trusted maritime partner for Command/U.S. 4th Fleet is the maritime component of U.S. Caribbean, Central and South America maritime forces leading to improved unity, security, and stability.

Below is a news release. Hopefully the Coast Guard is planning to participate. I would think an NSC or MEC, FRC, LEDET, and a fixed wing with Minotaur. ECity might even host a foreign aviation unit.

It should be pretty easy, the action will take place off the US East Coast, off Mayport, Camp Lejeune, and Norfolk, Sept. 15 to Oct. 6.

It will include a SINK-EX. The Coast Guard might even get a chance to shoot. (Don’t worry that we might sink the target prematurely.)
