SPOKANE VALLEY, WA – A General Dynamics subsidiary here will close in June, with 300 employees laid off.

Itronix, which builds rugged laptops and other mobile devices, will outsource production to US-based contract assemblers, a General Dynamics spokeswoman told Circuits Assembly. The company is currently reviewing potential suppliers, spokeswoman Fran Jacques added.

The company told workers the layoffs would start April 24, and final operations at the site would wind down in June. A source at the company said 60 positions would be given the option to relocate and 20 more would be offered telecommuting jobs.

While production will be performed by outside assemblers, engineering design will be moved to Sunrise, FL, Jacques said. "Itronix is still in the rugged computer business," she said.
