Developed from captured Wolfhound tanks which were purchased from Akiteiwa in limited quantity. Modified to better fit domestic production capabilities and available technologies.

122mm L/40 rifled gun

 * Ballistically equivalent to D-25T/D-49 122mm guns.
 * Chosen over available 107mm rifled gun with better AT performance due to Kasibaar having strong beliefs in tanks being for infantry support primarily, anti-tank use is secondary.

 * Unstabilised gun, gun never received a stabiliser in domestic models for cost reasons.
 * Underpowered engine
 * Limited range
