Abstract : The feasibility of a target-marking round capable of being delivered from light aircraft by a forward firing weapon was established. The study produced a marking round design which is 60mm in diameter and uses a sustainer rocket to augment the launch velocity and achieve a constant velocity to target. The round is designed to be fired from a low pressure, semi-recoilless launcher, is fin stabilized, and contains the rocket motor in a tandem configuration behind the marker assembly. Upon approaching the target, a proximity fuze in a nose of the marking round triggers a retrofire charge which expels the marker candle assembly rearward to overcome its forward velocity. This method for retarding the marker assembly was demonstrated successfully by a series of experimental retrofirings, including tests with actual marker candles. (Author)
