PT-802, also known as Torpedo Boat No.2, was the second vessel of the 1-Go torpedo boats operated by the Japan Maritime Self-Defence Force. Laid down in May 1955 at Hitachi Shipbuilding's Kanagawa facility, launched in August 1955 and commissioned November 1956 she was assigned to the Yokosuka District. PT-802 joined the newly formed 1st Torpedo Boat Squadron in November 1956, which was later reorganised in 1959. By March 1970, she was reclassified as a Special Service Ship, with a designation YAS-49, to serve in the Practical Experimentation Unit. Finally, she was decommissioned on 31 March 1973.

The Type 1, PT-802 is a Japanese motor torpedo boat introduced in Update "Dance of Dragons" as one of the later additions to the low-BR Japanese MTBs. Its main highlight is the 40 mm Bofors, making it one of the lowest BR vessels equipped with such a high-calibre autocannon (in this regard, it can be compared with the MAS 441, introduced in the same update). This impressive armament, however, comes at a cost, with several disadvantages: limited firing arcs, a fragile hull, sub-par torpedoes, and rocket-launched depth charges that are challenging to use.
