Understanding the Altitude Reach of a 120mm Mortar Shell

The altitude a 120mm mortar shell can reach depends on several factors including the type of mortar, the angle of elevation, and the charge used. Generally, a 120mm mortar can reach altitudes of approximately 1000 to 2000 meters (3280 to 6561 feet) above ground level when fired at a high angle.

Firing Factors Influence Reach Height

The optimal angle for firing a 120mm mortar shell is around 45 degrees, which can achieve these heights of 1000 to 2000 meters. However, the exact altitude can vary based on specific conditions and design. The type of mortar, the type of charge used, and even atmospheric conditions can impact the shell's altitude. For instance, a higher charge might provide a slightly greater reach but not drastically so.

Using a Trajectory Calculator for Precision

If you need more detailed information about a specific mortar model or firing conditions, a trajectory calculator can provide precise data. The calculator considers the speed and angle at which the shell is fired. For example:

Example - Charge 4, 318M/S, Elevation 89°: The round would go up to about 17000 feet. While this might seem impressive, it's important to note that in most practical scenarios, such a high altitude is not necessary or realistic. The typical altitude range for mortar attacks is much lower, usually within a kilometer or two.

When You Don't Need Rockets

Indirect fire is typically used for targets obscured by terrain or to provide suppression during an assault. High-altitude shells are not typically required unless you are engaging targets on high ground or facing unique tactical situations. In most fire support scenarios, the goal is to keep the rounds within a manageable altitude range, around 1000 to 1500 meters, to ensure accuracy and controllability.

Conclusion: Balancing Altitude and Accuracy

While the 120mm mortar shell can reach impressive heights, the actual altitude achieved is heavily dependent on the firing conditions and objectives. For most military operations, the focus is on achieving the right balance between altitude and accuracy. A combination of optimal angle, appropriate charge, and careful targeting will help achieve the desired result. If you have more specific questions, feel free to reach out!
