KBR, Inc. (formerly Kellogg Brown & Root) is a U.S. based company operating in fields of science, technology and engineering. KBR works in various markets including aerospace, defense, industrial and intelligence. After Halliburton acquired Dresser Industries in 1998, Dresser’s engineering subsidiary, the M. W. Kellogg Co., was merged with Halliburton’s construction subsidiary, Brown & Root, to form Kellogg Brown & Root. KBR and its predecessors have received many contracts with the U.S. military including during World War II, the Vietnam War, and the Iraq War. Democratic Congressman Lyndon B. Johnson, later President of the United States, was instrumental in providing government contracts for Brown & Root, in exchange for the company funding his campaigns and otherwise providing money to him.
