USCGC Pontchartrain (WHEC-70) was an Owasco class high endurance cutter built for World War II service with the United States Coast Guard. The ship was commissioned just days before the end of the war and thus did not see combat action until the Korean War.
Pontchartrain was built by the Coast Guard yard at Curtis Bay, Maryland, one of only two Owasco class vessels not to be built by Western Pipe & Steel. Named after Lake Pontchartrain, Louisiana, the ship was commissioned as a patrol gunboat with ID number WPG-70 on 28 July 1945. Her ID was later changed to WHEC-70 (HEC for "High Endurance Cutter"—the "W" signifies a Coast Guard vessel).[1] [2]
Pontchartrain was originally named Okeechobee. She was stationed at Boston, Massachusetts, from 1 April 1946 to 17 October 1947 [there is conflicting data that indicates station at Boston until 23 August 1948] and was used for law enforcement, ocean station, and search and rescue operations. She was subsequently decommissioned and stored at the Coast Guard Yard, Curtis Bay, MD, until 5 September 1948. She was re-commissioned and homeported at Norfolk, Virginia, until 12 November 1949. From 12 November 1949 to sometime in 1972 she was stationed at Long Beach, California. During her last 18 months, until decommissioning 19 October 1973, she was home-ported in Wilmington, NC. She was used for law enforcement, ocean station, and search and rescue operations in the Pacific and Atlantic.[3] On 4 May 1950, Pontchartrain assisted the disabled FV Eta near Catalina Island.
