General Dynamics will lay off 103 employees in Sierra Vista, the company confirmed Monday.

A company spokesman said the layoffs are of workers in its information technology business unit who work out of Fort Huachuca. He said the company has received less work from Raytheon, which holds the primary military contract. The layoffs go into effect Sept. 19.

Sierra Vista Mayor Rick Mueller said these types of layoffs are normal when the military reduces spending.

“They go through these contracting cycles, basically started a year and a half ago with the downsizing," Mueller said. "And we’ve had contracts restructured so there are fewer contractors at a lower salary rate that are basically doing the same job, and this is one of the things that happens when we move from a war footing to a peacetime footing in this community."

Mueller said Sierra Vista is trying to attract more tech companies to diversify its employer pool.
