BCA is a fundamentally different concept than standard monolithic plates for ballistic protection. The layering of smaller, lighter armor segments to better distribute the force of impact allows for both lighter weight than a solid slab and a degree of flexibility that slab could never possibly provide. BCA is based conceptually on living systems like snake skin or fish scales.
Origin - BCA is a ballistic armor design developed and patented by researchers at the University of Washington, earning its inventor a Distinguished Thesis award for its conception.
Method - BCA combines interlocking laminate layers of materials with complimentary qualities to achieve equivalent ballistic stopping power at lower weight and increased flexibility.
Reducing the weight of ballistic armor allows for a reduction in an infantryman’s combat load without sacrificing protection. Studies show this results in a dramatic increase in combat effectiveness and a consequent reduction in battlefield casualties.
