USCGC Ingham (WPG/WAGC/WHEC-35) is one of only two preserved Treasury-class United States Coast Guard Cutters. Originally Samuel D. Ingham, she was the fourth cutter to be named for Treasury Secretary Samuel D. Ingham. She was the most decorated vessel in the Coast Guard fleet and was the only cutter to ever be awarded two Presidential Unit Citations.

Mid-Ocean Escort Force (MOEF) referred to the organisation of anti-submarine escorts for World War II trade convoys between Canada and Newfoundland, and the British Isles. The allocation of United States, British and Canadian escorts to these convoys reflected preferences of the United States upon United States' declaration of war and the organisation persisted through the winter of 1942–43 despite withdrawal of United States ships from the escort groups. By the summer of 1943, United States Atlantic escorts were focused on the faster CU convoys and the UG convoys between Chesapeake Bay and the Mediterranean Sea; and only British and Canadian escorts remained on the HX, SC and ON convoys.
