WARDOGS Mortar & Artillery Calculator
L81 and SPH-2 firing solution from map coordinates or a known distance. Calculates range, bearing, azimuth MIL and elevation.
Community table: 132–684 m
If the shot lands short or long, enter the estimated miss distance. The calculator adjusts desired range and returns a new MIL solution.
Use the calculator above when you already have a gun position and target marker. In coordinate mode it calculates horizontal range, compass bearing, 6,400-mil azimuth and the current community firing-table elevation for the L81 Mortar or SPH-2. If you already know the range, switch to Distance Only and use it as a fast WARDOGS mortar elevation calculator.
Current-data note: the firing curves are community-maintained rather than developer-published. The calculator is based on the current open-source Apollyon weapon configuration checked on September 16, 2026. Its configured supported ranges are 132–684 m for L81 and 780–2,629 m for SPH-2. Use the result as a first-round solution and confirm with a ranging shot because WARDOGS balance or terrain behavior can change.
How the WARDOGS Mortar Calculator Works
The tool deliberately separates map geometry from weapon ballistics. WARDOGS gives you map coordinates, while the community firing solution converts those coordinates into three useful values: horizontal distance, bearing, and the weapon-specific elevation setting. This is more reliable than pretending there is one verified real-world ballistic equation for the game.
BULKHEAD has described WARDOGS as using real-world ballistics and flight models, but the developer has not published muzzle velocity, drag coefficients, gravity scale, shell coefficients, or a closed-form artillery equation for the L81 and SPH-2. Current community tools therefore use measured firing tables and interpolate between known range points. That distinction matters: the distance and bearing formulas are ordinary geometry, while elevation is build-specific community data.
How to Calculate Distance from Map Coordinates
In the current calibrated community map definitions used for Bakurani, Ozeti and Zestafona, one full coordinate unit equals 100 m. A difference of 0.10 is 10 m and 0.01 is 1 m. Treat the gun as point G and the target as point T.
| Value | Formula | Result |
|---|---|---|
| delta X | Target X - Gun X | East-west separation |
| delta Y | Target Y - Gun Y | North-south separation |
| Distance | 100 × sqrt(delta X² + delta Y²) | Horizontal range in meters |
| Bearing | atan2(delta X, delta Y), wrapped to 0–360° | Compass direction, north = 0° |
| Azimuth MIL | Bearing × 6400 / 360 | Horizontal azimuth on a 6,400-mil circle |
| Elevation | M1 + (D − D1) × (M2 − M1) / (D2 − D1) | Interpolated firing-table MIL |
Example: gun X80.00 Y70.00 and target X83.00 Y74.00 gives delta X = 3 and delta Y = 4. The diagonal is 5 coordinate units, so the range is 500 m. The same coordinates give a bearing of about 36.9° northeast, or roughly 656 azimuth mil.
Important: a 100 m target is below the configured L81 community-table minimum of 132 m, so the calculator correctly returns no elevation for L81 at 100 m. If L81 is selected, the out-of-range message must show 132–684 m; SPH-2 uses a different configured range of 780–2,629 m.

WARDOGS L81 Mortar Calculator
The L81 firing curve is not linear. The calculator finds the two community table points around your desired distance and interpolates between them. At 500 m, for example, the neighboring points are 494 m at 470 mil and 501 m at 460 mil, which gives about 461 mil.
For the current configured table the calculator only labels solutions from 132 to 684 m as in range. The underlying source contains some additional test points outside that configured window, but they are intentionally not treated as supported live range here.
L81 correction direction: in this table, longer range generally means a lower elevation number. If a correctly aimed shot lands short, move to a longer-range solution; if it lands long, move to a shorter-range solution. The correction helper above handles this automatically in meters.
WARDOGS SPH-2 Artillery Calculator: Low and High Arc
SPH-2 can return two different elevation solutions for the same ground distance. The low arc is available from roughly 1,181 m in the current table, while the high arc covers the shorter end down to the configured 780 m minimum. Where both branches overlap, the calculator displays both.
At 2,000 m, interpolation gives roughly 206 mil on the low arc and about 1,057 mil on the high arc. Low arc is flatter; high arc is steeper. Neither result includes a guaranteed terrain-clearance model, so a ranging shot still matters.
| Weapon / Arc | Configured range | 2,000 m example | As MIL increases |
|---|---|---|---|
| L81 | 132–684 m | Out of range | Range becomes shorter |
| SPH-2 low arc | ~1,181–2,629 m | ~206 mil | Range becomes longer |
| SPH-2 high arc | 780–2,629 m | ~1,057 mil | Range becomes shorter |
Terrain Height and Vehicle Tilt
The coordinate calculation gives horizontal ground range; it does not solve target height. If the target is higher or lower than the gun, treat that as separate context. The open-source community project exposes terrain elevation on supported maps, but its standard firing-table MIL remains distinct from terrain data, and vehicle/chassis tilt is not automatically solved by a simple universal rule.
For SPH-2, park as level as possible before recording the gun coordinate. A mathematically correct range can still miss if the chassis changes the actual barrel attitude. If you move the vehicle, recalculate the gun position instead of reusing the old solution.
How to Correct the First Ranging Shot
A miss tells you which part of the solution needs adjustment. Correct in a fixed order rather than changing everything at once:
- Left/right: correct bearing or update the target coordinate if it moved.
- Short: you need a longer-range solution. Use the correction tool above and enter the estimated short distance.
- Long: you need a shorter-range solution.
- Repeated inconsistent misses: check terrain height, SPH-2 tilt, gun movement, stale target coordinates, or a firing-table change in the current build.
Simple WARDOGS Fire Mission Checklist
- Record gun X/Y coordinates after the weapon is positioned.
- Record the freshest target X/Y coordinates.
- Select L81 or SPH-2 in the calculator.
- Calculate range, bearing and elevation.
- For SPH-2, choose a valid low/high arc solution.
- Check terrain and chassis attitude.
- Fire one ranging round.
- Correct short/long with the correction helper and left/right with bearing.
- Copy the confirmed fire mission for the gunner or squad.

WARDOGS Mortar & Artillery Calculator FAQ
Is this a real WARDOGS mortar calculator?
Yes. It calculates map distance and bearing directly from the coordinates you enter, then interpolates elevation from the current community L81 or SPH-2 firing table. It runs locally in your browser and does not require an external API.
What is the WARDOGS mortar range?
The community configuration used by this calculator marks 132–684 m as the supported L81 window. Treat that as a community-table range, not a developer-published hard maximum.
What is the WARDOGS SPH-2 range?
The current configuration marks 780–2,629 m as the supported overall SPH-2 range. Low-arc solutions begin around 1,181 m; high arc covers the shorter distances and overlaps low arc at longer ranges.
Why do I get two SPH-2 elevation values?
Because the same horizontal distance can be reached by a flatter low trajectory or a steeper high trajectory. The calculator shows both when both branches have a valid table solution.
Does the calculator compensate for hills?
No fixed terrain-to-MIL correction is presented as authoritative. The current tool calculates flat horizontal range and firing-table elevation. Use height difference as context and confirm with a ranging shot.
Can I calculate from distance only?
Yes. Select Distance Only, choose the weapon, enter meters, and the tool returns the corresponding firing-table elevation. Bearing and azimuth require gun and target coordinates.
Is the calculator official?
No. ExpCarry is not affiliated with BULKHEAD. The ballistic tables are community-maintained and the calculator should be treated as a practical companion tool rather than an official weapon specification.

Last verified: September 16, 2026. Community firing tables can change when WARDOGS balance changes; if the live game and this calculator disagree, trust the current game build and re-test a known range.
