The Ki-102 otsu (Designated: Type 4 Assault Aircraft) is a rank III Japanese twin-engine fighter with a battle rating of 3.0 (AB) and 3.3 (RB/SB). It was introduced in Update 1.35. The Allied reporting name for this aircraft was "Randy".
The Ki-102 otsu was a ground attacker version of the Ki-102 which in itself was a variant of the Ki-45.
The Ki-102 otsu has a decent speed advantage over most enemy planes in a straight line or dive and very good climb rate. The climb rate is typically better than almost every aircraft it will come up against. As with most Japanese heavy fighters, it is a very fast aircraft. The aircraft is as manoeuvrable as you would expect from a heavy fighter, though quite sluggish in a turn compared to a single engine aircraft. The Ki-102 otsu has good acceleration in a dive due to its two powerful engines and increased weight and decent acceleration when travelling in a straight line.

- Self-sealing fuel tanks (1 in central fuselage, 3 in each wing)
*Note that the gunner is rear-facing
Modifications and economy
The Ki-102 otsu is armed with:
- 1 x 57 mm Ho-401 cannon, nose-mounted (16 rpg)
- 2 x 20 mm Ho-5 cannons, chin-mounted (200 rpg = 400 total)
As a ground attacker, the Ki-102 otsu comes equipped with a 57 mm drum-loaded cannon to engage ground targets with but lacks shell choice and comes only with HE. The gun itself was based on the Ho-203 (37 mm) but increased in size. It lacks velocity and requires the pilot to be rather close to the target to hit anything at all which will make this plane very vulnerable when an attack is initiated.
Along with the Ho-401, it also comes with 2 x 20 mm Ho-5s which provide some good firepower for aerial targets and lightly armoured vehicles at a range unlike the Ho-401.
It is greatly advised to fire the guns separated.
The Ki-102 otsu is defended by:
- 1 x 12.7 mm Ho-104 machine gun, dorsal turret (500 rpg)
The Ki-102 otsu has a 12.7 mm Ho-104 in the back, which shouldn't be underestimated as it can leave the pursuer burning down to the ground, but the belts for it aren't very favourable as most of them are filled with AP. Universal offers the best single bullet but is only fired every 4 rounds and Default offers a better universality.
Usage in battles
Describe the tactics of playing in the aircraft, the features of using aircraft in a team and advice on tactics. Refrain from creating a "guide" - do not impose a single point of view, but instead, give the reader food for thought. Examine the most dangerous enemies and give recommendations on fighting them. If necessary, note the specifics of the game in different modes (AB, RB, SB).

Pros and cons
- Powerful 57 mm cannon
- Self-sealing fuel tanks and decent survivability, unlike many Japanese aircraft
- Weak defensive armament
- Rather slow for its BR
Describe the history of the creation and combat usage of the aircraft 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 vehicle and adding a block "/History" (example: https://wiki.warthunder.com/(Vehicle-name)/History) and add a link to it here using the
main template. Be sure to reference text and sources by using
<ref></ref>, as well as adding them at the end of the article with
<references />. This section may also include the vehicle's dev blog entry (if applicable) and the in-game encyclopedia description (under
=== In-game description ===, also if applicable).
