General info

Survivability and armour

Describe armour protection. Note the most well protected and key weak areas. Appreciate the layout of modules as well as the number and location of crew members. Is the level of armour protection sufficient, is the placement of modules helpful for survival in combat? If necessary use a visual template to indicate the most secure and weak zones of the armour.

Armaments

Main armament

Give the reader information about the characteristics of the main gun. Assess its effectiveness in a battle based on the reloading speed, ballistics and the power of shells. Do not forget about the flexibility of the fire, that is how quickly the cannon can be aimed at the target, open fire on it and aim at another enemy. Add a link to the main article on the gun: {{main|Name of the weapon}}. Describe in general terms the ammunition available for the main gun. Give advice on how to use them and how to fill the ammunition storage.

Usage in battles

Describe the tactics of playing in the vehicle, the features of using vehicles in the 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. Describe 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

Summarise and briefly evaluate the vehicle in terms of its characteristics and combat effectiveness. Mark its pros and cons in a 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".

History

Devblog

Following Japan’s remilitarization in the wake of the outbreak of the Korean War, Japanese engineers began working on the first domestic postwar tank designs. Taking on board the experience of working with American WWII tanks in service at the time, as well as incorporating some of the lessons learned from the Korean conflict, Japanese tank designers came up with a series of prototypes in the late 1950s.

The ST-A3 was created as one of the later prototypes and was based on the previous design - the ST-A2. Featuring a 90 mm cannon coupled with an autoloading mechanism in the rear of the turret, the design was considered successful, but ultimately wasn’t ordered into production due to concerns over its cost. As a result, the ST-A3 was modified into the ST-A4 by having its autoloading mechanism removed and eventually entered production as the Type 61 medium tank in 1961. Only two ST-A3 prototypes were constructed and closely resembled the later production model Type 61 visually.
