Northrop Grumman [NOC] last week said it has increased in investment in Australia through the award of three contracts totaling $7.4 million to three new global supply chain partners.

The contracts were awarded to Electro Optic Systems (EOS), CEA Technologies, and Insitec, which provide expertise in aerospace hardware development, space exploration services and software design.

“EOS, CEA Technologies and Insitec represent Australia’s vibrant defense industry and are key additions to our Australian industry team,” David Perry, vice president and chief global business development officer at Northrop Grumman, said in a statement. “Each of these relationships strengthens our ability to deliver products and services critical to maintaining the national security of the United States, Australia and our allies.”

The contracts build on a 2011 agreement between Northrop Grumman and Australia’s Department of Defense to identify opportunities for Australian industry to compete within the company’s global supply chain and those of its major suppliers.
