Design
Development
The Imperial Army Department of Tank Development, under commander the administration of Lord Jochen Behr, was issued the directive in late 1947 to design a new mainstay main battle tank capable of competing with those fielded by other Eraucran miliatires. At the onset of the Great War, the Shalumite military had primiarly fielded a fleet of light and medium tanks meant to act as cavalry support for mechanized and motorized units. While capable against opposing infantry groups, they lacked the necessary staying power to combat the more numerous and capable Æsthurlavaj vehicles. The Imperial Army, in an attempt to create a solution to the issue, pressed a heavier tank into service after reviewing several competiting designs from manufactuers across the country. While equipped with much heavier firepower and armor, they greatly lacked in mobilitly and suffered from numberous reliabilitly and maintaince issues. This forced the Imperial Army to rely more on foreign imports such as the Acrean Strv 72 and Strv 81 until the end of the conflict.
Lord Behr, who had worked alongside allied engineers throughout the war, wanted to avoid the poor performance that past models fielded by the army had experienced. In order to do this, he sought to replicate the emphasis placed on reliabilitly by their Acrean counterparts. After observing several blueprints and designs, which generally fell within the specifications outlined by his department, it was decided that the production contract would be rewarded to Askvig Defense Services AG based out of Dresden. Their prototypes featured thicker armor capable of withstanding direct hits from the Acrean 88mm guns, improved firepower in the form of a 105mm rifled cannon, telescopic gunner sights taht allowed for more accurate engagement while on the move, a more reliable powertrain, and a periscope instead of viewing slits.
Manufacturing was slated to take place at the Dresden Arsenal Tank Plant, a production center owned by the government and staffed with outside contractors. This decision was made due to the fact that many of Askvig AG's own facilities had been rendered inoperable during the course of the war and were still in the process of being repaired. Production of the intial sereis was sluggish due to issues with quality control, especially in regards to the engine and turret rotation systems.
