WASHINGTON — Engility Holdings, a Chantilly, Virginia-based contractor that counts the U.S. National Reconnaissance Office among its key customers, appointed former Raytheon exec Lynn Dugle to take over as chief executive March 21.

Dugle, who retired as president of Raytheon’s Intelligence, Information and Services business last March, replaces Anthony Smeraglinolo, who has stepped down. No reason was given for Smeraglinolo’s departure.

Hynes was chief executive  of TASC, a Chantilly-based contractor that Engility acquired in 2014 for $1.1 billion in stock.
