IRON NEST Ballistic Calculator
Use the IRON NEST ballistic calculator to solve direct and spotter-relay reports, calculate bearing and range, and review labeled community firing values.
Calculate a Direct or Spotter-Relay Solution
Enter Gun X, Gun Y, Target bearing, and Target range, or switch to Spotter Relay for two linked vectors. The calculator reports the final target coordinate, bearing, range, mil bearing, and a copyable fire order.
When to Use Each Mode
Direct mode projects one bearing and range from the gun position. Spotter Relay mode first locates the observer from the gun, then projects the observer-to-target report while preserving the original gun as the final firing origin.
Review Community-Reference Firing Values
The firing table lists applicable charge and elevation combinations from a pinned community model. It is not official game data and should be checked against the in-game calculator for the current build.
Inputs, Outputs and Model Limits
Bearings use north as 0° and increase clockwise. Distances must be finite and non-negative. The geometry runs locally in your browser.
