General Dynamics [GD] yesterday said that Gerard DeMuro, the long-time head of its Information Systems and Technology (IS&T) group, is stepping down on Feb. 28 to pursue professional opportunities elsewhere.

DeMuro, 57, joined GD in 1999 through the acquisition of GTE Government Systems and became the executive vice president of IS&T in 2003.

IS&T consists of four divisions: Advanced Information Systems, C4 Systems, Information Technology, and United Kingdom Limited. GD said that the companies that comprise IS&T will report to GD Chairman and CEO Phebe Novakovik until a successor is named.

“Jerry DeMuro has made significant contributions to General Dynamics over the past 14 years that have enhanced shareholder value and deserve our recognition,” Novakovik said in a statement. “We wish him continued success in his future pursuits.”

IS&T struggled last year, losing $1.4 billion as its sales declined nearly 11 percent as the group suffered from goodwill impairment charges, award delays and a slow ramp up on some programs transitioning to production.
