Calabasas engineering services provider National Technical Systems Inc. said Tuesday that a division had completed the acquisition of a supply chain management services provider named Unitek Technical Services Inc.

Terms of the all-cash transaction by NTS’s NQA division were not disclosed.

Unitek, which was a unit of French firm Bureau Veritas, will continue to be based in Centreville, Va., near Washington. Current management and employees are expected to remain with the firm, whose clients include aerospace and defense suppliers.

“Unitek’s technically advanced, web-based system will allow our clients, suppliers and field resources the ability to access data in real time, which can provide a range of unique value-added services,” said Chief Executive William C. McGinnis, whose company serves the defense, aerospace, telecommunications, automotive and high technology industries.

NTS shares closed up 2 cents, or less than 1 percent, to $5.42 on the Nasdaq.
