Defense and intelligence company Raytheon, which has large operations in Goleta, reported a 4.5 percent increase in sales for the third quarter of 2017, for a net income of $572 million.

The missile systems segment led the company’s growth, with a 10 percent increase in net sales to $1.95 billion, and integrated defense systems rose 4 percent to $1.33 billion. Total revenues reached $6.3 billion, and operating expenses also edged up more than 4 percent to over $5.4 billion.

“We delivered strong bookings and solid operating performance in the third quarter,” Chairman and CE Thomas Kennedy said in a news release Oct. 26. “Global customer demand drove an increase in our backlog, which positions us well for continued growth in 2018.”
