The armor, known as EXO Scale, is an appliqué that can be added to vehicles already in use. At recent tests at the Aberdeen Test Center, Army engineers fired projectiles at EXO Scale armor, which "conclusively passed the live fire test, proving the viability of EXO Scale for MRAP [Mine Resistant Ambush Protected] II vehicles and as an upgrade to earlier generation MRAP I vehicles," the release explains.
EXO Scale clearly provides better protection for our deployed soldiers, said Maj. Gen. Buff Blount (US Army, ret). EXO Scale weighs approximately 30 percent less than the government's current appliqué armor design. That translates to extended vehicle life, lower operations (fuel) costs and lower maintenance costs due to less wear and tear on the vehicle. He went on to point out that EXO Scale is approximately one-third the cost of current MRAP armor solutions.
In addition to its use as an appliqué, EXO Scale is also being employed on the cutting-edge new Grizzly vehicle from Blackwater (pictured above).
