Uji was a Japanese, Taiwanese, and finally Chinese gunboat from World War II and the post-war period. The keel for this unit was laid in 1940, the launch took place in September of the same year, and entry into service - in 1941. The length of the ship was 78.5 meters and a width of 9.7 meters. Full displacement reached about 1,000 tons, and maximum speed - to about 19-20 knots. The deck armament, at the time of launching, consisted of three 120 mm guns and two 25 mm anti-aircraft guns.
Uji was one of two Hashidate-class gunboats. The construction of the gunboat was approved in the 1937 plan for the expansion of the Japanese navy, and its construction took place at the Osaka shipyard. Shortly after entering service, the ship was directed to the waters surrounding China and took a very active part in the Japanese-Chinese war of 1937-1945. Uji continued to operate in China shortly after the attack on Pearl Harbor. In 1943, the unit underwent modernization, which consisted in strengthening the anti-aircraft armament. A year later (1944) a depth charge launcher was added. In April 1944, Uji took part in the cover of the convoy heading to New Guinea. Later, gunboat was used to cover ships bound for Okinawa and Taiwan. In January 1945, Uji returned to Chinese waters. At the end of that year, it was taken over by the Kuomintang, and at the end of 1949, it fell into the hands of Chinese communists, who used the ship (under the name of Nan Chang) probably until the beginning of the 1980s.
