BOSTON – A study conducted by the Mass. Military Asset and Security Strategy Task Force and the University of Massachusetts Donahue Institute released an economic-impact study that indicates Massachusetts’ six military installations support more than 45,000 jobs and contribute more than $13.7 billion to the state’s economy annually.

The study found that in fiscal 2011, the six military installations directly employed 14,500 full and part-time active, reserve and guard military and civilian personnel. By investing $9.1 billion in fiscal 2011, the bases contributed to another $4.6 billion in spending and added more than 30,600 jobs to the Massachusetts economy.

The military installations include: Westover Air Reserve Base in Chicopee; Barnes Air National Guard in Westfield; the U.S. Army’s Soldier Systems Center in Natick; Fort Devens; Hanscom Air Force Base; and the Massachusetts Military Reservation on Cape Cod. •
