This page provides a comprehensive guide to the CDK variables that affect different aspects of a missile’s flight performance, including speed, aerodynamics, guidance type, and more. A detailed list of all documented variables and their meanings.
Stat Card Variables
Note: These variables affect the missile's displayed stat-card values rather than its flight performance.
| Variable | Effect On Missile | Units |
loadFactorMax | Maximum G force of the missile | G |
rangeMax | Maximum range of the missile | m |
Seekers
Note: While these variables change the behaviour of the missiles, it should still be noted that aspects of the aircraft it is locking onto still matter (such as size, amount of engines and engine heat).

These variables change how the missile behaves while in flight, changing how much drag it has and setting the maximum speed the missile is aerodynamically limited to.
| Variable | Effect On Missile | Units |
startSpeed | Speed the missile will start at, if it is zero it gets the velocity of the vehicle | m/s |
endSpeed | Maximum speed limit that the missile can achieve | m/s |
maxDistance | How far a missile is allowed to travel from its point of launch | m |
timeLife | How long a missile is allowed to travel from its point of launch | s |
CxK | In flight drag coefficient | - |
finsAoaHor | Maximum horizontal fin deflection angle (from 0 to 1) | finsAoa × 90° |
finsAoaVer | Maximum vertical fin deflection angle (from 0 to 1) | finsAoa × 90° |
