GTR is the nucleus of a new industrial complex in northeast Mississippi. American Eurocopter, a subsidiary of EADS North America, moved into an helicopter production plant built by the airport and leased to the company on airport property in 2004. In 2007 American Eurocopter finished the second phase of the project, a facility built primarily to manufacture and assemble the new U.S. Army UH-72A Lakota Light Utility Helicopter. Severstal North America opened a steel mini-mill in an adjacent site in October 2007 and immediately began construction on phase II, bringing total investment in the plant to $1.8 billion. Paccar, parent company of Peterbilt, Kenworth and DAF (Dutch) trucks has operated a truck engine manufacturing facility since late 2010 that is located to the north of the airport. Other industry, many with international roots, continues to locate at the industrial park adjacent to the airport. The area has two "Megasites" adjacent to the airport that were certified under the Tennessee Valley Authority's Certified Megasite program. In addition, two aerospace companies, Aurora Flight Sciences and Stark Aerospace, built facilities on airport property and primarily manufacture unmanned aerial vehicles. Stark Aerospace is the newly formed subsidiary of Israel Aerospace Industries.
