Described is a shaped charge warhead comprising an axially symmetric fragmentation casing designed to define a containment space and having in a base portion a casting hole for the explosive, a detonator housed in the casting hole and a conical liner of the shaped charge positioned inside the containment space. The casing and the conical or hemispherical liner, with a variable thickness, if necessary, are made in a single piece. The casing extends along a respective axis of extension in such a way as to also define a standoff of the charged warhead.

A shaped charge warhead comprising: an axially symmetric casing designed to define a containment space and having in a base portion a casting hole for the explosive; a detonator housed in said casting hole; a conical or hemispherical shaped charge liner positioned inside the containment space; characterised in that said casing and said conical liner are made in a single body, said casing extending along a respective axis of extension in such a way as to also define a standoff of the shaped charge warhead. Claim: 2. The shaped charge warhead according to claim 1, wherein said cylindrical casing and said conical or hemispherical liner are made by additive manufacturing. Claim: 3. The shaped charge warhead according to claim 1, wherein said conical or hemispherical liner has a variable thickness. Claim: 4. The shaped charge warhead according to claim 1, wherein said conical or hemispherical liner has a structure with cellular partitions, each cellular partition containing non-sintered powder. Claim: 5. The shaped charge warhead according to claim 1, wherein said conical or hemispherical liner is connected to the cylindrical casing by a continuous connection made with non-sintered spaces. Claim: 6. The shaped charge warhead according to claim 1, wherein said warhead is made of additive manufacturing powders of copper, aluminium alloys, tungsten, bismuth or zirconium alloys. Claim: 7. The shaped charge warhead according to claim 1, wherein a base portion of said cylindrical casing has geometrical defects in the form of volumes of powder which are non-sintered and/or geometrical discontinuities in the thickness. Claim: 8. A method for producing a shaped charge warhead according to claim 1, comprising the steps of: making a casing and a conical liner defining a single body using an additive manufacturing technique; introducing explosive through said casting hole of the cylindrical casing in a space formed between said casing and said conical liner; closing said casting hole housing a detonator in said casting hole. Claim: 9. The production method according to claim 8, wherein said cylindrical casing and said conical liner are made by additive manufacturing by powder bed fusion. Claim: 10. The production method according to claim 8, also comprising a step of performing a thermal treatment after the step of making the single body and a step of surface finishing following a removal of forging supports. Current International Class: 42; 33; 42
