CDK Missile Variables

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.

F-35C Usermodel created by Noffie firing an AIM-9L with AIM-9X flight performance.

Stat Card Variables

Note: These variables do not affect flight performance, instead they affect what the stat card says about them (in this case they are redundant as they cannot be viewed)

VariableEffect On Missile
loadFactorMaxMaximum G force of the missile
rangeMaxMaximum range of the missile

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).

Infrared Seeker Variables

VariableEffect On Missile
rangeBand0Rear aspect maximum lock distance
rangeBand1All aspect maximum lock distance
fovField of view of the missile, often the small circle on the HUD (degrees)
lockAngleMaxHow far the seeker can traverse before launch, often the larger circle on the HUD (degrees)
angleMaxHow far the seeker can traverse after launch (degrees)
warmUpTimeTime it takes to warm up the infrared seeker (seconds)
workTimeHow long the seeker can remain active (seconds)
gateWidthInner field of view of the IR seeker, generally ignoring new heat sources outside of it
minAngleToSunHow close the missile has to look towards to sun before locking it (degrees)

Aerodynamics

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.

VariableEffect On Missile
startSpeedSpeed the missile will start at, if it is zero it gets the velocity of the vehicle (m/s)
endSpeedMaximum speed limit that the missile can achieve (m/s)
maxDistanceHow far a missile is allowed to travel from its point of launch
timeLifeHow long a missile is allowed to travel from its point of launch
CxKIn flight drag coefficient
finsAoaHorMaximum horizontal fin deflection angle (from 0 to 1) (finsAoa × 90°)
finsAoaVerMaximum vertical fin deflection angle (from 0 to 1) (finsAoa × 90°)

Maneuverability

These variables change how the missile can turn and deflect itself towards a target.

VariableEffect On Missile
reqAccelMaxThe maximum amount of G force a missile is allowed to pull
thrustVectoringAngleAngle of which the missile can deflect its thrust
massMass of the missile before being fired
massEndMass of the missile after rocket motor has burnt out
loadFactorLimitMaximum amount of G force an aircraft can pull while still being able to fire the missile
timeOutAmount of time a missile is forced to fly straight before moving towards a target

Velocity

These variables are responsible for changing the velocity of the missile.

VariableEffect on missile
forceAmount of force the motor of a missile will produce (Newtons)
timeFireHow long the force will be applied (Seconds)
