Review of Development and Key Technologies of Reactive Armor and Anti-Reactive Armor

This paper provides a systematic summary of the development of an explosive reactive armor (ERA). It details the structural characteristics and protective performance of typical ERA from the first to fourth generation, along with an in-depth analysis of how the ERA interferes with the shape charge jet (SCJ). This study also reviews current research on anti-ERA technology, particularly focusing on tandem-charge warhead penetrating without detonation technology. Finally, it forecasts the future trends of ERA and anti-ERA technologies, in conjunction with existing advancements to enhance armor protection and ammunition damage capabilities.
