Alion Science and Technology, an employee-owned technology solutions company, today announced it received a new contract valued at $2 million from the Marine Corps Systems Command (MARCORSYSCOM) to support the Expeditionary Fighting Vehicle (EFV) alternate bow flap concept development. The single-award contract has a 15-month base period of performance, running from April 7, 2008 through July 7, 2009.

Alion will analyze the current design of the EFV bow flap, and a new concept developed by the Naval Surface Warfare Center Carderock Division, making any needed modifications to improve structure, reliability and performance. As part of this contract, Alion will design, build, install and test a new EFV bow flap prototype using its program management, system engineering, Naval architecture, hydrodynamic analysis, mechanical design and ProE computer-aided design experience. The plan is to build and test the prototype off the coast of California.

"This new customer contract will provide Alion a chance to demonstrate its proven expertise in design, testing and improving structural efficiency and reliability as well as enhancing operational performance," said Kenneth Siegman, Alion's JJMA Maritime and Industrial Engineering Group Manager. "Alion has the tools, personnel and capabilities to verify the sea loads and apply them using dynamic analysis tools to improve the reliability of the EFV bow flap concept. A simpler, lighter and more robust bow flap will add to mission dependability, reduced maintenance time and cost, and improve the ride quality of the EFV in its water mode."

The EFV is an armored amphibious vehicle capable of seamlessly transporting Marines from Naval ships located beyond the visual horizon to inland objectives. It serves as the primary means of tactical mobility for the Marine Rifle Squad. Alion engineers will perform the work from the company's Alexandria, Va., Pittsburgh and Washington, DC, offices. Alion's subcontractors for this program include Craig Technologies, Jered, LLC and consultant Joe Koelbel.
