Improving protection
US to develop largest single-piece aluminum hull for combat vehicles


Alcoa and the US Army Research Laboratory have launched a cooperative effort to develop an aluminum solution to a grave threat to soldier safety: Improvised Explosive Devices (IEDs).

The solution, a single-piece aluminum hull for ground combat vehicles, would replace today’s assembled hulls and deliver even greater strength and durability. In addition to safety benefits, the single-piece hull would reduce vehicle weight and assembly time, and, therefore, overall cost.

For decades, the Army has recognized the survivability benefits of a single-piece hull due to its thickness, size and shape for ground combat vehicles. This collaborative effort to develop continuous and seamless aluminum hull technology has the potential to be a game changer for how combat vehicles are designed and made to better protect our soldiers.

Alcoa’s single-piece aluminum hull would improve combat vehicle performance through:

•Improved blast protection: A single-piece hull would eliminate welded seams used in today’s manufacturing processes, which is expected to significantly improve protection. The single-piece hull would cover the entire lower section of any combat vehicle.
