 In August 2012, General Dynamics was awarded an ACV Hull Survivability Demonstrator contract for the design, fabrication, and test support of a full-scale hull to demonstrate crew-protection technologies.In November 2012, they conducted simulated mine-blast tests on their ACV ballistic hull design, successfully meeting mine-blast survivability requirements.Work concluded by May 2013 and will be used to refine requirements for effective protection against under-vehicle threats.
