'''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 '''{{Specs|name}}''' 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.

=== Survivability and armour ===
{{Specs-Fleet-Armour}}
<!-- ''Talk about the vehicle's armour. Note the most well-defended and most vulnerable zones, e.g. the ammo magazine. Evaluate the composition of components and assemblies responsible for movement and manoeuvrability. Evaluate the survivability of the primary and secondary armaments separately. Don't forget to mention the size of the crew, which plays an important role in fleet mechanics. Save tips on preserving survivability for the "Usage in battles" section. If necessary, use a graphical template to show the most well-protected or most vulnerable points in the armour.'' -->

== Usage in battles ==
<!-- ''Describe the technique of using this ship, the characteristics of her use in a team and tips on strategy. Abstain from writing an entire guide – don't try to provide a single point of view, but give the reader food for thought.

If necessary, note the specifics of playing with this vehicle in various modes (AB, RB, SB).'' -->

=== Pros and cons ===
<!-- ''Summarise and briefly evaluate the vehicle in terms of its characteristics and combat effectiveness. Mark its pros and cons in the bulleted list. Try not to use more than 6 points for each of the characteristics. Avoid using categorical definitions such as "bad", "good" and the like - use substitutions with softer forms such as "inadequate" and "effective".'' -->

'''Pros:'''

* The Bofors L/60 Mark 3 autocannon provides excellent firepower

'''Cons:'''

* Very awkward gun placement: The superstructure prevents firing forward, and the torpedo tubes limit gun depression
* Wooden structure cannot withstand even low-calibre machine gun fire
* No secondary or anti-aircraft (AA) armament: Incoming enemy aircraft must be detected in time and manually engaged
* Torpedoes have a low explosive yield and are among the slowest in the game
* The rocket-powered depth charges lack aiming tools and have a significant flight time, making them very unlikely to hit anything other than the largest, slowest vessels.

== History ==
<!-- ''Describe the history of the creation and combat usage of the ship in more detail than in the introduction. If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the ship and adding a block "/History" (example: <nowiki>https://wiki.warthunder.com/(Ship-name)/History</nowiki>) and add a link to it here using the <code>main</code> template. Be sure to reference text and sources by using <code><nowiki><ref></ref></nowiki></code>, as well as adding them at the end of the article with <code><nowiki><references /></nowiki></code>.

PT-802, also known as Torpedo Boat No.2, was the second vessel of the 1-Go class torpedo boats operated by the Japan Maritime Self-Defence Force in the post-war period. She was laid down on 18 May 1955 at Hitachi Shipbuilding's Kanagawa facility, launched on 6 August 1955 and commissioned on 15 November 1956.

The 1-Go torpedo boats were notable for their wooden hulls, constructed from Taiwanese cypress for the exterior planking and zelkova wood for structural components. PT-802 featured a modified V-shaped hull (named by the Japanese designers Omega-plane (オメガプレーンであ)), intended to enhance speed and manoeuvrability. Powered by two Mitsubishi YV20ZC15/20 diesel engines, each producing 2,000 horsepower, the vessel was capable of sustaining 30 knots. Its armament included a single [[Bofors L/60 Mark 3 (40 mm)|40 mm Bofors Mark 3]] mounted on the aft deck, two [[7.2 in T37|Mousetrap anti-submarine rocket launchers]] on the foredeck, and two HO-101 533mm torpedo tubes positioned amidships on both sides.

Upon commissioning, PT-802 was assigned to the Yokosuka District (横須賀地方隊) of the JMSDF. On 16 November 1956, it joined the newly established 1st Torpedo Boat Squadron (第1魚雷艇隊) alongside Torpedo Boats No.1, No.5, and No.6. The squadron was reorganised on 1 June 1959. During its service, PT-802 contributed to coastal defence operations and participated in various naval exercises.

On 2 March 1970, the vessel was reclassified as a special service ship and renamed YAS-49 (abbreviation for Special Service Ship 49 - が特務船49号). It was then assigned to the Practical Experimentation Unit, where it played a role in testing and development of a new tactics and as a technology test-bed. PT-802 was decommissioned on 31 March 1973, concluding its 17-year service in the JMSDF.
