Arthur Schuh, a Lieutenant (Junior Grade) in the United States Navy Reserve stationed in Portland, took several photographs of this captured Italian submarine as it docked at the U.S. Naval base in Casco Bay. The Navy likely used this vessel in anti-submarine warfare training.

During Schuh's service in Portland, he captured photographs of military life during World War II, many of which depict rarely-seen images of Naval activity and locations. Some of these subjects include a captured Italian Submarine, U.S. Navy Headquarters, Frontier Base, H.E.C.P at Fort Williams, Navy Supply Pier, Casco Bay Net Depot, U.S. Navy Fuel Depot, and the U.S. Navy Fleet Signal Station on Great Diamond Island.
