A study was made concerning the use of ballistic systems in launching diversionary objects from ballistic missiles. It as concluded that the use of standard cartridge-actuated devices CAD as decoy launchers is entirely feasible with each particular unit covering a certain weight-velocity range. The design of a reactionless launcher to cover any specific weight-velocity combination is possible for the ranges tabulated. This launcher could be either spigot or full- caliber, depending on the weight-velocity range desired. It was concluded that the use of a highlow ballistic spigot system is not desirable where a smaller caliber direct system can be used. If launcher weight or the G loading on the decoy is critical and a spigot design is used, the open spigot will give reduced values, in which case, the use of a high-low ballistic system ay be desirable. In fact, the pressures may become so low that the use of compressed gas or a mechanical system is recommended. Equal or greater launcher weight savings can be obtained by choosing aluminum or titanium over steel.
