The patent US6393991B1 titled “K-charge—a multipurpose shaped charge warhead” reveals a highly adaptable warhead designed for different battlefield needs. It uses a shaped charge liner with an angle over 70°, sealing a cavity filled with explosives. What makes it unique? The detonation method can be selected in the field.
And using our Global Patent Search tool we found about that with peripheral detonation, the warhead creates a fast, narrow jet for precise penetration. A central detonation generates a slower, wider penetrator, perfect for larger targets. And by combining both methods, multiple fragments are produced. The liner itself can even be made from composite materials for added versatility.
The real advantage? This warhead’s ability to adjust to the situation at hand, leaving us curious about how it can transform the outcome in various combat scenarios.
