A steamship, often referred to as a steamer, is a type of steam-powered vessel, typically ocean-faring and seaworthy, that is propelled by one or more steam engines that typically move (turn) propellers or paddlewheels. The first steamships came into practical usage during the early 1800s; however, there were exceptions that came before. Steamships usually use the prefix designations of "PS" for paddle steamer or "SS" for screw steamer. As paddle steamers became less common, "SS" is assumed by many to stand for "steamship". Ships powered by internal combustion engines use a prefix such as "MV" for motor vessel, so it is not correct to use "SS" for most modern vessels.
The Japanese aircraft carrier Taiyō was the lead ship of her class of three escort carriers. She was originally built as Kasuga Maru (春日丸), the last of three Nitta Maru class of passenger-cargo liners built in Japan during the late 1930s for NYK Line. The ship was requisitioned by the Imperial Japanese Navy (IJN) in early 1941 and was converted into an escort carrier. Taiyō was initially used to transport aircraft to distant air bases and for training, but was later used to escort convoys of merchant ships between Japan and Singapore. The ship was torpedoed twice by American submarines with negligible to moderate damage before she was sunk in mid-1944 with heavy loss of life.
Chūyō was a Taiyō-class escort carrier originally built as Nitta Maru, the first of her class of three passenger-cargo liners built in Japan during the late 1930s. She was requisitioned by the Imperial Japanese Navy (IJN) in late 1941 and was converted into an escort carrier in 1942. She spent most of her service ferrying aircraft, cargo and passengers to Truk until she was torpedoed and sunk by an American submarine in late 1943 with heavy loss of life.
Un'yō was a Taiyō-class escort carrier originally built as Yawata Maru (八幡丸), one of three Nitta Maru-class cargo liners built in Japan during the late 1930s. She was transferred to the Imperial Japanese Navy (IJN) during the Pacific War, renamed, and was converted into an escort carrier in 1942. The ship spent most of her service ferrying aircraft, cargo and passengers to various bases in the Pacific. Un'yō was badly damaged by an American submarine in early 1944. After repairs were completed in June, the ship resumed transporting aircraft and cargo. During a return voyage from Singapore in September, she was sunk by the submarine USS Barb.

After serving with the Guion Line and operating on trans-Pacific routes with the Canadian Pacific Railway Company, she was refitted and renamed Victoria.
The Design 1095 ship was an Emergency Fleet Corporation (EFC) design for a troop transport to be built at New York Shipbuilding Corporation and delivered to the United States Shipping Board (USSB) that, at the end of World War I hostilities, was modified to a combined passenger and cargo vessel. The contract was for thirteen ships, EFC hulls 2579 though 2591, but later adjusted to seven ships with the remainder being changed during construction to the slightly larger ships of EFC Design 1029 built from the start as passenger and cargo ships rather than being modified from the troop ship plan.
