Most importantly, this design is able to stop. 30 caliber armor-piercing bullets U. Military designation M2 AP at a velocity of 2,880 ft/s. Whereas such a threat would punch through most plates, and even other ceramic plates would likely collapse after one hit, this plate has been tested to successfully stop as many as three successive M2 AP rounds.
Ceramic plates stop rounds in a unique fashion: Rather than the mere hardness of the plate outmatching the strength of the bullet, ceramic armor allows a section of itself to shatter so as to absorb the bullet's impact more completely. The downside of this method is that the shattering process can hurt the integrity of the plate. But further development and higher-quality materials have enabled the C2 Multi-Hit to limit that shattering to a much smaller area, leaving the rest of the plate strong enough to stop more hits. 30 caliber (AP) bullets with a specified mass of 10.8g (166gr) and a velocity of 2,880 ft/s (+/- 30 ft/s).
