Royal Italian Navy had submarines built, and named them for Italian colonies, such as Italian East Africa, which was Italian colony located where?
Adua-class submarine The "Adua"-class submarine was the fourth sub-class of the 600 Series of coastal submarines built for the Royal Italian Navy ("Regia Marina") during the 1930s. There were 17 submarines in this class, almost all named after places in Ethiopia which had been an Italian colony since 1936, but only one, "Alagi" , survived World War II. Three submarines of this class ("Gondar", "Ascianghi", and "Neghelli") were sold to Brazil before the war and replaced with submarines of the same names.
HMS Escort (H66) HMS "Escort" was an E-class destroyer built for the Royal Navy in the early 1930s. Although assigned to the Home Fleet upon completion, the ship was attached to the Mediterranean Fleet in 1935–36, during the Abyssinia Crisis. During the Spanish Civil War of 1936–1939, she spent considerable time in Spanish waters, enforcing the arms blockade imposed by Britain and France on both sides of the conflict. "Escort" was assigned to convoy escort and anti-submarine patrol duties in the Western Approaches, when World War II began in September 1939. During the Norwegian Campaign, the ship escorted ships of the Home Fleet, although she did tow her sister HMS "Eclipse" after the latter ship had been badly damaged by German air attack. "Escort" was assigned to Force H in late June, and participated in the Attack on Mers-el-Kébir in early July. She was torpedoed a few days later, by an Italian submarine, but was towed for three days towards Gibraltar before she foundered.
