GD's Heebner To Retire

David Heebner, who heads General Dynamics' information systems and technology business, will retire at the end of the year, and S. Daniel Johnson, president of General Dynamics Information Technology, will take over starting Jan. 1, the contractor announced today.

Heebner, 69, took over the IS&T group in 2013 after leading the combat systems business since 2010. He previously served as the head of the contractor's marine systems business from 2008 to 2010 and president of General Dynamics Land Systems from 2005 to 2008. Heebner joined General Dynamics in 2000 after a nearly 33-year career in the Army, retiring as a lieutenant general.

Johnson, 67, has led GDIT since 2008. In his new role, he will continue to oversee GDIT as well as General Dynamics Mission Systems, the unit that will be created Jan. 1 by merging the contractor's advanced information systems and C4 systems businesses.
