Abstract An explosive flechette launching system which includes a central core expive driver having stacked coaxially thereabout a plurality of disc plates which have layered and sandwiched therebetween for radial launching a multiplicity of flechettes. In one embodiment, the flechettes are oriented and pointed in a radial direction and each are provided with divergent tail piece which is releasably fitted into a mating recess in a driver piston abutting said explosive driver. The fin assembly is provided with a central bore and is slidably carried by the flechette body so that when disposed in said launching system, the fin assembly is positioned at the pointed end thereof and supported by wedge supports along the fins and intermediate the disc plates. The entire assembly is protectively encapsulated or covered with a thin membrane or skin. The explosive driver is designed to provide or generate a radial plane, high pressure wave for launching the flechettes. In the other embodiment the flechettes are oriented, between the plates, transverse to the direction of flight or side launch to provide a relatively large surface area against which the explosive energy can act.
An explosive launcher for and including sub-projectiles which comprises: means for explosively generating a radially directed explosive plane wave including selective initiating means, a plurality of spaced apart plate members extending radially from and coaxial with said generating means, said sub-projectiles disposed and sandwiched intermediate adjacent of said plates and oriented for releasable radial flight, means for supporting said plates and said sub-projectiles, and pusher means intermediate said sub-projectiles and said generator means for transmitting the thrust forces generated to said sub-projectiles and thereby launching the same, wherein said sub-projectiles are flechettes each having a slender cylindrical body portion terminating at one end in a point and at the opposite end in a rearwardly divergent flattened portion, and a fin-assembly coaxially disposed about said body for sliding movement thereabout, said flechettes supported for and directed in an outward radial direction with said fin assembly disposed proximate said one end.
