Description

The Ki-109 in the garage

The Ki-109 is a Rank I Japanese twin-engine fighter with a battle rating of 1.7 (AB), 2.0 (RB), and 2.3 (SB). This aircraft was introduced in Update 1.71 "New E.R.A".

Based on the Mitsubishi Ki-67 'heavy' bomber, the Ki-109 was designed as an interceptor in an attempt to counter the American bombing raids that devastated Japan. It is armed with a 75 mm anti-aircraft gun modified for aircraft use, and almost all defensive armament from the bomber version has been stripped, except for the tail turret, in order to maximise performance.

Ingame, the Ki-109 functions much as it was intended to in reality. The 75 mm gun is effective against bombers, but struggles to hit small agile targets such as fighters. Its own defensive armament is very poor, and it should avoid combat with fighters at all costs. Alternatively, the 75 mm gun is also effective against tanks if a clean hit can be obtained.

History

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 If the historical reference turns out to be too big, take it to a separate article, taking a link to an article about the vehicle and adding a block "/ historical reference" (example: https://wiki.warthunder.com/Name-vehicles/historical reference) and add a link to it here using the main template. Be sure to include links to sources at the end of the article.

Media

An excellent addition to the article will be video guides, as well as screenshots from the game and photos.
