The USCGC Escanaba (WPG-77) was a 165 ft (50 m) "A" type United States Coast Guard cutter stationed on the Great Lakes from her commissioning in 1932 until the start of U.S. military involvement in World War II in 1941. With the outbreak of war, Escanaba redeployed to participate in the Battle of the Atlantic, during the course of which she was ultimately lost with nearly all hands. Struck by either a torpedo or mine in the early morning of 13 June 1943, while serving as a convoy escort, Escanaba suffered a fiery explosion and sank within minutes, leaving only two survivors and one body out of her 105-man crew to be found on the surface by rescuers.

The Defoe Shipbuilding Company was a small ship builder established in 1905 in Bay City, Michigan, United States. It ceased to operate in 1976 after failing to renew its contracts with the United States Navy. The site of the former company is now being developed for business and housing on the bank of the Saginaw River.
