The DH55 main gun is a smoothbore gun, meaning it has a barrel without rifling, which allows for the firing of high-velocity, fin-stabilized ammunition.
This design provides increased accuracy and range compared to traditional rifled guns. The gun's caliber is 120mm, which is a widely used size for main battle tanks and other armored vehicles.
The DH55 main gun incorporates an auto-loading system, which eliminates the need for a separate loader crew member. This improves the overall efficiency of the vehicle and reduces the crew size required. The auto-loader can store several rounds of ammunition internally, allowing for rapid and continuous firing without the need for manual reloading.
The gun is equipped with an advanced fire control system that includes a ballistic computer, range finder, and thermal imaging capabilities. This system provides the gunner with accurate targeting information, even in low-light or adverse weather conditions. It also enables the gun to engage moving targets effectively.
The DH55 main gun is capable of firing a wide range of ammunition types, including armor-piercing fin-stabilized discarding sabot (APFSDS), high-explosive anti-tank (HEAT), and high-explosive (HE) rounds. The APFSDS rounds are designed to penetrate heavily armored targets, while the HEAT rounds are effective against armored vehicles and fortifications. The HE rounds are used for engaging soft targets such as infantry or light vehicles.
The gun's effective firing range exceeds several kilometers, allowing the vehicle to engage targets from a safe distance.
It also features a high rate of fire, which ensures a rapid response in combat situations. The precise targeting capabilities of the DH55 main gun, combined with its powerful ammunition, make it a formidable weapon on the battlefield.
The gun is integrated with a stabilization system that reduces the effects of vehicle movement on the accuracy of the firing. This feature is crucial for engaging targets while the vehicle is on the move or when traversing rough terrain. The stabilization system ensures that the gun remains on target, even under challenging conditions.
