In 1999, the company acquired Teledyne Ryan, developer of surveillance systems and unmanned aircraft, California Microwave, Inc., and the Data Procurement Corporation. On March 19, 1999, Northrop Grumman announced to restate its fourth-quarter results downward to a net loss because of problems related to its dealings with start-up satellite launch company Kistler Aerospace Corp. In 1999, Northrop Grumman and SAIC created AMSEC LLC as a joint venture, which grew "from $100 million in revenue in 2000 to approximately $500 million in fiscal year 2007."
