Alcoa Defense Awarded Contracts for Joint High-Speed Vessel Aluminum Tie Downs

Alcoa (NYSE:AA) announced today that it has been awarded a subcontract
from Austal USA to produce aluminum tie downs for the Joint High-Speed
Vessel (JHSV). The 10 JHSV ships, slated for completion by 2015, will be
the U.S. military′s first aluminum catamaran fleet.

'We are excited to be working with Austal on this groundbreaking fleet,?
said David Dobson, president, Alcoa Defense. 'Through our design and
engineering expertise, we are helping to expedite the manufacturing
process for the fleet while simultaneously making aluminum shipbuilding
more affordable.?

Designed to secure cargo, equipment and vehicles in the JHSV′s mission
bay, the all-aluminum tie downs are 50 percent lighter than conventional
steel tie downs. The tie downs will be manufactured from high-strength
aluminum by Alcoa′s facility in Auburn, Ind. By providing the finished
tie downs, Alcoa Defense helps Austal streamline the supply chain and
achieve its lean manufacturing goals.

'We are now applying decades of experience in creating subassemblies for
a variety of industries to build innovative, high-quality marine
structures,? said Scott R. Kerns, vice president and general manager,
Alcoa Transportation Products. 'Alcoa makes it easier and more
affordable for shipyards to integrate aluminum structures in their
vessels.?

Collaboratively developed by Alcoa and Austal USA, the all-aluminum tie
downs were designed to replace traditional steel tie downs, which
require a more expensive, complex, labor-intensive process for joining
and installation. The aluminum tie downs offer the same structural
strength and performance as steel at a fraction of the weight and
installed cost. Additionally, the aluminum tie downs enhance the
long-term durability and structural integrity of the JHSV because,
unlike steel, they will not produce galvanic corrosion when attached to
the JHSV′s aluminum deck.

The announcement of the tie down subcontract follows Alcoa being awarded
the subcontract for sheet and plate and Austal′s recent keel laying for
Spearhead, the first JHSV. Keel laying, which historically meant the
laying down the central or main timber that established the backbone of
a vessel, is now the symbolic recognition of the start of the
shipbuilding process. Spearhead, a U.S. Army vessel, will be a 338-foot
aluminum catamaran capable of transporting troops and their equipment,
supporting humanitarian relief efforts, operating in shallow waters and
reaching speeds in excess of 35 knots when loaded to peak capacity.
Spearhead is the first of 10 JHSVs to be jointly operated by both the
U.S. Army and the Navy.
