Abstract
A wall breaching explosive fragmentation ammunition having a tungsten alloy nose cap with ceramic cone nose which make possible penetration into a hardened target with survivability of the warhead. The ammunition employs a unitary construction with fuze completely within the projectile's shell case. The ammunition has an external plastic rotating band which also encloses an induction antenna. The antenna may signal the fuze on a wire, through a hole in the shell case. The fuze signals may be fed through a gun barrel, then picked up on the antenna. The ammunition also employs a controlled pattern fragmentation mechanism incorporating a patterned plastic liner.
Claims3
A wall breaching explosive fragmentation ammunition for launching through a gun barrel, said ammunition comprising:
- a solitary steel fragmentation shell case (100) enclosing a fuze (103) having a fuze length (200), explosive (109), a rear enclosure piece (130), and a hole patterned plastic liner (112) further embedded between the explosive and an interior surface of the steel fragmentation shell case, said liner fabricated from low density, low melting temperature, viscous-elastic-plastic material, and such that a layer (300) of ammunition at least 3 to 4 mm deep is disposed between the interior surface of the shell case (100) along the length (200) of said fuze (130);
- a tungsten alloy nose cap (106), said nose cap further overlaid with a ceramic cone (107), and;
- a plastic rotating band (115) around the exterior of said shell case, said plastic rotating band enclosing an induction antenna (118), and;
- a hole (127) through the shell case, and a wire (121) electrically connecting said induction antenna to said fuze within said shell case, and wherein;
- said hale in the steel case around the wire, and also the space between the rotating band and the shell case, are filled with low melting temperature electric insulator material (124), and;
- wherein communication to the fuze is accomplished through signals fed to the gun barrel, such signals then being effectively picked up electromagnetically by said induction antenna.
