London, who joined CACI back in 1972 and became CEO and president in 1984, will stay at CACI as chairman, according to a CACI release.

In a statement, London said that the preparation for the transition began more than a year ago, meaning CACI plucked Cofoni from his job at CSC in 2005 knowing that he would be the next CEO.

Cofoni had been president of CSC’s federal business when he left for CACI. He initially joined General Dynamics in 1974, but moved over to CSC when the company bought part of General Dynamics in 1991.

CACI said it will continue its aggressive pursuit of mergers and acquisitions as it works toward its goal of becoming a tier-one defense contractor. While it won’t be building bombs and planes like Lockheed Martin or Northrop Grumman, iCACI hopes to compete for engineering and IT work with these firms as well as other big defense players, such as General Dynamics, SAIC, and CSC.

CACI share were up 3% on the New York Stock Exchange to close at $51.90 on Thursday.
