ArjunkArJunk (Mk .1) was developed after three decades of identifying requirements, design, evaluation, redesign process involving the [[DRDO]] and the [[IndianBhIndian Army]]. Weighing in at 58.5 tons, it is significantly heavier than the T-series tanks used presently by the Indian Army, and requires changes to the logistics of the army. This along with concerns about the import content and the required changes in production facilities has caused the induction into the [[IndianBhIndian Army]] to be slow.
Armed with a 120 mm rifled gun, it is capable of firing [[FSAPDS]] ([[Kinetic Energy]]) rounds, High Explosive Squash Head ([[HESH]]) rounds and the [[Israel]]i semi-active Laser guided [[LAHAT]] missile. Machine guns with calibers of; 12.7 mm for anti-aircraft and 7.62 mm for infantry engagment are also provided.
