The Li-Jien Dynamics Z6 Chungmu (Zhenian: Z6 충무), commonly the Z6 Chungmu Main Battle Tank and also referred to as Azure Dragon MBT due to its project name at the time of development, is a 3.5th-generation main battle tank built in Zhenia. Developed as a modern main battle tank to complement the existing Z5 Temujin main battle tank and replace the aging Z4 Thunder main battle tanks within service of the Greater Eastern Union Army, it is equipped with numerous characteristics that have been implemented after tactical feedback from recent military tensions, such as the 120 mm/L55 smoothbore cannon, its networking systems and its array of active protection systems. Its most recent variants, particularly the Z6A2, are considered as fourth-generation main battle tanks, due to significant upgrades that distinguish it from existing variants.
As the main backbone of the Greater Eastern Union Army's armored units, almost 5,000 units have been produced and are in service within the Greater Eastern Union Defense Forces, while Z6A1 units are rapidly replacing existing Z5 Temujin tanks in the Marine Corps. The chassis upon which the main battle tank is built has been developed to serve other purposes, including engineering vehicles, assault breaching units or heavy infantry fighting vehicle for intensive urban warfare. Its chassis, dubbed the Common Combat Platform - Heavy (CCP-H), has evolved to serve as the baseline of other non-tank vehicles as well. Variants of the Z6 Chungmu have also been vouched for export across numerous nations.
Development
While existing and upgraded variants of the Z5 Temujin proved to be an effective main battle tank early on, its platform was reaching its limits by the late 1980s. While the usage of the 105 mm smoothbore cannon (120 mm/L44 smoothbore in upgraded variants) and other then-advanced technology, as well as the design philosophy centered around four crew members, were effective early on, its armor and armament were being outdated in the midst of advancements in armored technology across the world. Variants of the Z5 Temujin partly solved the armament and armor problem, but the limits of the platform, without much change, were showing by the early 1990s, calling for a drastic replacement design.
In response to such demands, Li-Jien Dynamics, forming a consortium with Jinmu Defense Industries, began working on a proposal for a next-generation main battle tank to complement and ultimately replace the Z5 Temujin, forming its philosophy around a three-man crew with an autoloader. Although it was met with challenging designs from Shinjin Technologies by 1994, it won the contract to supply the said new main battle tank in 1995. Development of associated technologies set to be applied to the new main battle tank - new HEAT/APFSDS rounds, gun-launched ATGMs, and active protection systems - progressed in tandem with the development of the vehicle itself, parallel to other vehicle developments in the Greater Eastern Union Defense Forces.
The first production prototype of the Z6 was introduced in late 1996, although the first operational units didn't see service until 1998. The production prototypes showed minor improvements from Li-Jien Dynamics' proposal. Although it was initially anticipated that it would not be procured in large amounts, the Greater Eastern Union Army, after being satisfied with the overall performance of the vehicle, shifted its plans and decided to field the new tank in larger amounts than expected; the existing technological advancements derived from it were used to update the Z5 Temujin. The new main battle tank was later designated as the 'Z6 Chungmu', after the term 'Chungmu-gong' given to the highest warriors and military commanders in Zhenian history.
