Captive missiles are used by Air Forces mainly in the following cases : 1/ Pilot training (Target Acquisition and Lock-on) 2/ Weapon Qualification for launch by a specific platform, fixed or Rotary wing. Ordtech manufactures two types of above missiles dimensionally identical to the original weapon. All other properties, namely aerodynamic characteristics, weight, momentsof inertia, etc. exactly much those of the live weapon : One without a rocket motor but with a seeker head which is used for target lock-on without firing ability and another with a rocket motor which enables safe separation from the aircraft. The latter version has no G&C (Guidance and Control) and is manily used for Qualification of the weapon. The motor characteristics (impulse, exhaust plume, etc.) match those of the live weapon. These missiles cost a fraction of the live weapon and offer tremendous savings to the Air Force operator. In addition to low cost realistic training these missiles offer protection of the war-stock from natural attrition. The latter is common occurence in Air Forces inventories, where live rounds are subjected to high dynamic loads during hard manouvres and landings. Most common failure, verified by NDI and other testing methods is the existence dangerous cracks in propellant body, which may result to missfiring or explosion due to non-uniform propagation of burn-front during ignition.
