Unyō Maru

Un'yō was a Taiyō-class escort carrier originally built as Yawata Maru, one of three Nitta Maru-class cargo liners built in Japan during the late 1930s. She was transferred to the Imperial Japanese Navy 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.
