NORFOLK, Va. (AP) — BAE Systems is laying off about 650 workers at its Norfolkshipyard.

According to media outlets, the company said Monday that the layoffs will be effective Nov. 20. The shipyard employs about 1,500 people.

The company said in a statement that the cuts are the result of a “decrease in Navy repair work, consistent with the Navy’s decision to delay several modernization programs and the reduced number of Navy ships homeported in Norfolk.”

The announcement comes a week after Huntington Ingalls Industries Inc.’s Newport News Shipbuilding laid off 480 salaried workers.

BAE Systems provides ship repair, maintenance, modernization, conversion, and overhaul for the Navy and other customers. It has seven full-service shipyards in Alabama, Florida, California, Virginia and Hawaii, and has a total of about 5,000 employees.
