Why is "Taiyō-class escort carrier" trending?

Wikipedia Overview

The Taiyō-class escort carrier was a group of three escort carriers used by the Imperial Japanese Navy (IJN) during World War II. Two of the ships were built as cargo liners in the late 1930s and subsequently taken over by the IJN and converted into escort carriers, while the third ship was converted while still under construction. The first ship converted, Taiyō, ferried aircraft and supplies to Japanese possessions before the start of the Pacific War in December 1941 and also served as a training ship between transport missions. Once the war began she did much the same for the newly conquered areas. Her sister ship, Un'yō did much the same in 1942. Chuyō, the last of the three to be converted, only ferried aircraft between Japan and the naval base at Truk before she was sunk by an American submarine in December 1943. Her sisters sometimes had destinations other than Truk in 1943, but it was also their primary destination until they were damaged by American submarines in late 1943 or early 1944. After finishing their repairs in 1944, the sisters combined convoy escort duties with their transport missions and often ventured as far south as Singapore. Taiyō was the first of the pair to be sunk, torpedoed by an American submarine in August, with Un'yō following her sister a month later.
