State officials say Department of Defense spending in North Carolina has exceeded $4 billion.
The spending in fiscal year 2009 was a 10 percent increase over the $364 million spent in the year before.
Gov. Beverly Perdue said the numbers indicate that the state is becoming a significant player in the military and defense industry.
The state says 86 of North Carolina's 100 counties have businesses that performed defense-related work last year.
A 2008 Department of Commerce study found that the military has a $23 billion impact on North Carolina's overall economy.
