Reinald W. Carter, who guided Baltimore-based Allied Research Corp. through a period of rapid growth and a return to profitability, will retire at the end of this year as chairman and chief executive.
Mr. Carter will be succeeded as chief executive by Jay R. Sculley, who has been president and chief operating officer since May, the company said this week. He has been a director since early 1991. The chairman's position will remain vacant, at least temporarily, the firm said.
