|Fate||Acquired by Northrop Grumman|
|Headquarters||Milwaukee, Wisconsin, U.S.|
During the 1960s, the company began acquiring many unrelated firms and became one of the largest conglomerates in the United States. At its peak, in addition to many defense related companies, it also owned both Royal Typewriters and Adler, Moffat major appliances, Stouffer's frozen foods, and various office equipment and furniture companies.
Like many conglomerates, the company suffered significant declines in the 1970s, selling off many of its unrelated brands and had largely returned to its defense roots by the 1980s. The company continued to shrink after the ending of the cold war and by the late 1990s was a corporate takeover target. The company was purchased by Northrop Grumman in 2001.
Litton started in 1953 as an electronics company building navigation, communications and electronic warfare equipment. They diversified and became a much bigger business, with major shipyards, and manufacturing microwave ovens.
In the early 1990s, Litton Industries split into separate military and commercial companies. The US$2 billion commercial business, which included Litton's oilfield services, business and automated assembly line operations, was named Western Atlas, Inc.
The early "li" logo was designed by Robert Miles Runyan, but was modified in 1986 by designer Gregory Thomas after a worldwide comprehensive study and analysis of the corporate identity. For much of the early 1980s and 90s, "li SWEDA" and "li COLE" were commonly found on product goods but it was modified to bring emphasis to the parent company, whose name was little known.
In 1998, Litton Industries bought TASC, Inc.. In 2000, TASC sold three stand-alone commercial operations: Adesso Software, WSI (Weather Services International) Corporation and Emerge. In 2001, Northrop Grumman bought Litton Industries.
