'''Viper Dart''' is an American [[sounding rocket]] originally developed in 1972. Space Data Corporation (SDC) developed the vehicle as a mean to increase the apogee of the [[Super Loki]] boosted PWN-12A dart. The PWN-12A dart is the non-propulsive second stage that contains a [[ROBINSphere]] (Radar OBservable INflation Sphere). The ROBINSphere is a calibrated weight inflatable 1 meter diameter radar reflecting balloon, weighing in at about 150 grams.  The weight is measured within one-half gram.<ref name=ROBINSPHERE>{{cite web|last1=Robert Leviton|first1=John B.
