  • Incendiary fragmentary warhead
    Patent number: 4351240
    Abstract: A warhead comprising an explosive charge surrounded by discrete individual etal fragments is increased in effectiveness by the addition of pyrophoric fragment material combined therewith. For this purpose, misch metal or zirconium-tin sleeves are placed around or within the fragmentation layers or, alternatively, a percentage of the ferrous metal cubes are replaced with a number of preformed zirconium fragments.

  • Linear shaped charge warhead
    Patent number: 3934511
    Abstract: A large warhead explosive is provided with a metal liner having longitudi corrugations. The shape of the liner causes the warhead to deliver concentrated amounts of energy to targets at some distance from the point of detonation. This energy is in the form of hypervelocity fragment beams produced by what is known as "Monroe effect" caused by the jetting of the liner as the detonation wave front progresses along the warhead.
