The '''{{Specs|name}}''' was a prototype for the Type 73 APC meant to replace the smaller [[Type 60 ATM|Type 60 APC]]. Going through multiple prototypes, this particular version was tested with a [[Rh202 (20 mm)]] as a self-defense and anti-air cannon, though this armament would not see use in the final version.

The '''{{Specs|name}}''' is a rank {{Specs|rank}} Japanese SPAA {{Battle-rating}}. It was introduced in [[Update "Apex Predators"]].

It was introduced in [[Update "Apex Predators"]]. The SUB-I-II provides an excellent fire rate with the possibility of an APDS belt in an amphibious yet squishy APC hull only offering up to 20 mm of armour. As such, if positioned correctly against a suitable target, the {{PAGENAME}} can utilize the APDS autocannon to shred their opponent apart.

The SUB-I-II has no notable armour. It is dangerous to stand in the open without cover, as the SPAA can be penetrated by any tank or plane. The turret is open topped which can allow for weapons of any type to damage the gunner. The survivability of this SPAA is very low if any enemy has a direct line of sight on it.

When hunting for planes, the SUB-I-II should always have some sort of cover to hide behind in case a plane retaliates. When shooting, you should also be mindful of the gun overheating and use all of the rounds in the belt as the SUB-I-II has only 800 rounds at most. If possible, try to remain near a friendly capture point to restock on ammo belts when they run out because the main cannon can shoot at 800 rpm.

Development of the Type 73 APC started in 1967 as a replacement for the Type 60 APC (chassis of the [[Type 60 ATM]]). Four prototypes were made during the development, two from Mitsubishi (SUB-I-I and SUB-I-II) and two from Komatsu (SUB-II-I and SUB-II-II). The 20 mm Rh202 version got rejected at last.
−
 
 
−
Based on the influence of the Vietnam War as well as on the experiences from using the American M113 APC, the Japanese military concluded several drawbacks on their Type 60 APC. Namely, it was deemed that the vehicle had slightly poor mobility, lacked amphibious capabilities and had no NBC protection systems in place. As a result, in 1964 various Japanese companies, including Mitsubishi, began work on addressing some of these drawbacks by conducting tests with experimental platforms. By 1967, the Defense Agency laid out the requirements for a new APC design and contacted several companies to produce different parts of the vehicle.
 
−
 
 
−
Furthermore, four prototype versions were ordered for testing from Mitsubishi and Komatsu. Both companies had to produce a version with steel armor plating as well as one made from aluminum. While Mitsubishi’s aluminum-based prototype would in the end be selected as the most suitable design and would thus form the basis for the subsequent production version of the Type 73 APC, it was also selected to conduct different tests.
 
−
 
 
−
Namely, during testing, the SUB-I-II prototype, as it was known, also had a Rheinmetall 20mm turret mounted on its roof to test the feasibility of evolving the Type 73 from a pure APC into an IFV design. However, due to various technical issues and an increased cost, it was decided not to pursue this design choice further. As a result, the Type 73 would end up remaining a pure APC design, without substantial armament fitted to it.

SUB-I-II

Description

The Mitsubishi SUB-I-II is a rank Japanese SPAA with a battle rating of (AB), (RB), and (SB). It was introduced in Update "Apex Predators".

General info

Survivability and armour

SUB-I-II has no notable armour anywhere and its dangerous to be anywhere without cover, as the SPAA can be penetrated by any tank or plane that it can face in ground RB, AB or SB. The survivability of this SPAA is very low if any enemy has direct line of sight on it!

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.

Armour type:

Armaments

Main armament

Main article: Rh202 (20 mm)

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

Development of the Type 73 APC started in 1967 as a replacement for the Type 60 APC (chassis of the Type 60 ATM). Four prototypes were made during the development, two from Mitsubishi (SUB-I-I and SUB-I-II) and two from Komatsu (SUB-II-I and SUB-II-II). The 20 mm Rh202 version got rejected at last.
