Foxhole Arty Calculator Formula
This calculator uses a simplified, inverse square relationship model for accurate field adjustments. The core relationship is based on Range (R) being inversely proportional to the square of the adjusted Firing Angle (A-H), scaled by the Fire Factor (F).

Variables
- Range (R, meters): The measured distance between the artillery piece and the target location.
- Firing Angle (A, mils): The elevation setting on the artillery gun’s sight. Crucial for determining the parabolic arc.
- Fire Factor (F): A variable representing the ballistic properties of the shell type (e.g., 120mm shell is different from a 150mm shell).
- Altitude Difference (H, meters): The difference in height (elevation) between the gun’s position and the target’s position. Positive if the target is higher, negative if lower.

What is Foxhole Arty Calculation?
Artillery calculation in Foxhole refers to the process of determining the correct firing elevation (Angle, or mils) needed to hit a target at a specific distance (Range). Unlike simple line-of-sight weapons, artillery fires indirectly, launching a shell into a high parabolic trajectory.
Precision is paramount. Even small errors in range or angle, or failing to account for terrain altitude, can lead to costly misses. Tools like this calculator automate the complex mathematics, allowing artillerists to focus on deployment and coordination, ensuring that shells land precisely on enemy fortifications or troop positions.
The “Fire Factor” accounts for the different ballistic curves of various ordnance types (e.g., 120mm, 150mm), which have different weights and muzzle velocities, fundamentally altering the relationship between angle and range.
How to Calculate Foxhole Arty (Example)
Suppose you are firing a standard 120mm shell (Factor F=1.0) at a target 300 meters away, and the target is 10 meters higher than your gun (H=10). We need to solve for the Firing Angle (A).
- Identify Known Variables: R = 300, F = 1.0, H = 10, K = 50000.
- Select the Angle Formula: The required formula is $A = H + \sqrt{\frac{K \times F}{R}}$.
- Substitute Values: $A = 10 + \sqrt{\frac{50000 \times 1.0}{300}}$.
- Calculate the Core Value: $50000 / 300 \approx 166.67$.
- Find the Square Root: $\sqrt{166.67} \approx 12.91$.
- Determine the Final Angle: $A = 10 + 12.91 = 22.91$ mils. This is the angle you should set on your artillery sight.
Frequently Asked Questions (FAQ)
What is the typical range for artillery in Foxhole?
The effective combat range for most standard artillery pieces (like 120mm) typically falls between 150 and 400 meters, though maximum ranges can be higher. Always check the specific gun’s limitations.
Why is the Fire Factor (F) important?
The Fire Factor (F) compensates for different shell ballistics. A higher caliber shell (like 150mm) will have a higher factor, meaning it carries more kinetic energy and achieves the same range at a lower angle compared to a 120mm shell.
What happens if the Altitude Difference (H) is negative?
If the target is lower than your gun, H will be a negative number (e.g., -5 meters). The calculator automatically handles this subtraction in the formula $(A – H)^2$ to maintain accuracy, often resulting in a slightly higher required angle.
What unit is the firing angle measured in?
The firing angle (A) is typically measured in ‘mils’ (milliradians) within the game’s interface. This system allows for easy scaling and adjustment on the map and gun sight.
