1943  CG-85006 (ex-Catamount) exploded off Ambrose Light while on Coastal Picket patrol duty.  Of a total of ten crew members on board, four drowned while five were reported missing.  Only the commanding officer, CBM Garfield L. Beal, USCG, escaped.  He was picked up six hours later by a passing merchant ship.  The cause of the explosion was never ascertained.

1964  An earthquake which hit 9.2 on the Richter scale and an ensuing tsunami struck Alaska, killing 125 people and causing $311 million in property damage.  Coast Guard units responded in what was called “Operation Helping Hand.”  Within two hours of the earthquake, which began at 1732 local time, CGCs Storis, Minnetonka, and Sorrel were ordered to Prince William Sound; Bittersweet to Seward; and Sedge to Valdez.  “The following morning, three fixed-wing aircraft from Air Detachment Kodiak surveyed the damage while helicopters evacuated those in need.   By March 31, most of the direct assistance had been rendered and the task of repair and clean up began.  Approximately 360 civilians were evacuated from villages and isolated areas in Kodiak Island and Prince William Sound.  Storis was diverted to Cook Inlet for icebreaking duties in the Port of Anchorage until 18 April.” [Kenneth Arbogast, et al, The U.S. Coast Guard in Kodiak, Alaska, p. 15.]  A number of the Coast Guard stations in the area sustained damage, some of it severe.  The only Coast Guard fatality occurred when the tsunami struck the light station at Cape St. Elias and one crewman, EN3 Frank O. Reed, was swept out to sea and perished.

2003  During Operation Iraqi Freedom CGC Wrangell, homeported in Portland, Maine, along with a Coast Guard HH-65 Dolphin helicopter from Air Station Honolulu, escorted the first waterborne humanitarian aid shipment into the port of Umm Qasr without incident, while members of Coast Guard Port Security Unit 311, from San Pedro, California, assisted other coalition forces protecting the harbor.  The shipment, consisting of vital aid donated by numerous countries, was carried aboard the British ship RFA Sir Galahad.

1963  Three new 44-foot Motor Lifeboats departed the Coast Guard Yard for their designated stations.  Two were assigned to stations in the Third Coast Guard District, Sandy Hook Lifeboat Station and Eatons Neck Lifeboat station, while the third was assigned to Chatham Lifeboat Station in the First Coast Guard District.

1968  The Secretary of Transportation released his Report on Recreational Boat Safety. The report contained a detailed explanation of the proposed legislation and the programs the department intended to undertake.

1993  A Colonial Pipeline Company pipe ruptured, spilling 400,000 gallons of diesel fuel into the Sugarland Run creek in Herndon, Virginia.  The EPA requested the assistance from the National Strike Force.  Other units mobilized for the clean-up operation included a helicopter from AIRSTA Cape May, an air-eye HU-25 from AIRSTA Cape Cod, personnel from MSO Baltimore, CGC Capstan, and reservists from the region.  The strike team used the new DESMI 250 skimmer and pump to control the spill.  Coast Guardsmen assisted with the cleanup and safety operations as well as provided technical assistance.  By April 2, Colonial Pipeline, who claimed responsibility for the spill, had more than 250 contract personnel handling cleanup operations.  The strike teams stayed on site to monitor the cleanup.  The last strike team member left the spill site on April 10.
