NASHUA, N.H. (AP) - Connecticut-based Axsys Technologies is doubling the size of its Nashua, New Hampshire, plant.

The publicly traded company has hired 100 people so far this year, bringing its work force up to 360 employees.

The company makes high-performance cameras and optics and is a longtime supplier to BAE Systems in Nashua and Merrimack. Axsys spokesman Jeff Nestel-Patt said the company will move its program for gyro-stabilized camera systems used to mount on law enforcement helicopters from its Grass Valley, Calif., site to Nashua. Design and engineering work will remain in Grass Valley.

The Nashua operation is part of the company's Surveillance Systems Group. The corporate headquarters is Rocky Hill, Conn.
