The release mechanism includes a biasing device having a biasing force less than the acceleration forces developed on launch which oppose operation of the release mechanism so that the flaps are held in during booster thrust and are released and urged outwardly on {HEAD ~ booster} thrust {TAIL ~ termination} to brake the booster and separate it from the remainder of the missile
