 When the missile reaches a key acceleration point (indicating that it has cleared the launch tube), the ESAF initiates a second arming signal to fire the flight motor.After another check on missile conditions (target lock check), ESAF initiates final arming to enable the warheads for detonation upon target impact.When the missile strikes the target, ESAF enables the tandem warhead function (provide appropriate time between the detonation of the precursor charge and the detonation of the main charge).
