Alcoa Defense To Supply ArmX Aluminum Armor Kits To Oshkosh For HEMTT

October 12, 2011

WASHINGTON–Alcoa announced today that it will supply ArmX aluminum armor kits to
Oshkosh Defense for the Heavy Expanded Mobility Tactical Truck (HEMTT)
A4. The c-kit armor provides blast protection for the underside of the
vehicle. The announcement was made today at the AUSA show in Washington,

“We are excited about partnering with Oshkosh to provide kitted ArmX
assemblies, which provide excellent blast protection against improvised
explosive device (IED) threats,” said Alcoa Defense President David
Dobson. “We offer the complete value proposition of latest products and
program management to provide highly engineered subassemblies to our OEM
partners if they desire.”

Alcoa provides all elements of R&D through design and fulfillment to
allow for unique solutions to move to market quickly. “Though these
assemblies are complex, through our knowledgeable program management, we
are meeting our customers’ lead times at 100 percent delivery
performance,” says Victor Marquez, General Manager of Alcoa
Transportation Products, where the kits are fabricated.

ArmX armor plate was formed with special practices to fit the HEMTT’s
c-kit blast shield. Original equipment manufacturers (OEMs) can purchase
ArmX forgings or plate, or they can acquire complete ArmX subassemblies
that can easily be integrated into their vehicles.

“We made Oshkosh’s design concept for their HEMTT blast shield a reality
by producing the 14 subassembly components,” said Dobson. “Our aluminum
manufacturing expertise allowed us to take two-inch thick ArmX plate,
which is made from the ballistic temper of alloy 7085, and form it into
complex shapes. Alcoa’s unique capabilities in bending thick plate while
maintaining its strength is unmatched by other manufacturers.”
