KADM MK.2

Funky Trees Air Defense Missile

A completely funky trees guided missile designed to hit air targets at medium range and any altitude. No part of the missile is guided using the in-game missile guidance system. It can do many things the in-game default missiles cannot do, the biggest of which is gliding and continuing to guide toward the target once fuel has run out.

AI Usage

  1. Download and spawn as Aggressive on any ground surface
  2. Fly within 30km/18mi of the missile and it will start tracking you
  3. The missile can be temporarily defeated using countermeasures, however, it will attempt to re-acquire lock of the player as long as there is still fuel on board

Player Usage

  1. Spawn in and simply acquire lock on any air target, press fire, and enjoy the fireworks

Stats and Abilities

Max speed: Mach 4+
Altitude range: Below 60,000 feet
Target lock range: 30km/18mi
Flight range: Under ideal conditions, approximately 40-50 km or 25-31 mi
G-load: 40G+
Guidance time: 60 seconds

  • At high altitudes, the missile pulls less but flies faster
  • The missile possesses proximity detonation abilities, however, it is not very reliable
  • The missile will self-destruct once the 60 seconds guidance time has ended
  • The missile will continue to track the target once the fuel is depleted, and there will be no more smoke trails, making it extremely hard to spot with the naked eye.

Dodging the Missile

  • Countermeasures will affect the missile in that the rocket motor will be disabled until it re-acquires lock. The guidance and the control surfaces are not affected by countermeasures; if the missile has enough momentum or is in its glide phase it will still hit you with its nominal accuracy
  • The best way to defeat the missile is to fly at high altitudes directly above the launch site and to make the missile fly directly upwards; it has trouble tracking targets properly when it is pointed straight up. This is the only instance where you have a chance in outmaneuvering the missile
  • Flying away from the missile while it is launched within 10-12 miles of the player is not advised as you can not under normal circumstances outrun the missile if your plane has a reasonable max speed (mach 2-3)
  • If you are far enough away and have a very good air to air missile, it is very much possible to shoot the missile down as it is a relatively big missile

How It Works

  • The flight computer is placed on board the missile so that it can collect data and make corrective commands
  • 3 PID functions control all of the control surfaces and direct them to where it wants the missile to go to hit a target
  • One PID function controls the roll of the missile. It simply keeps the missile level at all times
  • One PID function controls pitch, where it keeps the pitch angle of the missile towards a calculated angle based on the target elevation, how fast the target elevation is changing, the acceleration of the target elevation (essentially the kinematic equation), and the angle of attack. The calculated angle is also multiplied by a factor based on distance from the target and the altitude to help the missile lead the target
  • One PID function controls the yaw, there is keeps the missile pointed at a calculated heading based on the target's heading, the speed at which the target heading is changing, and the acceleration of the target heading (again a kinematic equation, spherical coordinates if you will), and the angle of slip. It is then again multiplied by a factor based on distance from the target and the altitude to lead the target

Known Problems

  • The proximity detonation/self-destruct is sometimes unreliable, causing the missile to not be fully destroyed or create a big enough explosion
  • The missiles function is highly dependent on your devices performance; lagging can cause the missile to miss its target and or fail to launch off the rails
  • The launch platform, unless placed at Wright Airport, will not point exactly at the target when it is acquiring launch, causing the missile to take waste time and energy to get on course. I have yet to find a solution to this problem
