Chart: How Booz Allen Hamilton Swallowed Washington

Because it provides the government with data services rather than fighter jets—and because so much of its work is classified—Booz Allen Hamilton (BAH) doesn’t have the name recognition of government contractors like Lockheed Martin (LMT) or Boeing (BA). That changed on June 9, when a Booz employee, Edward Snowden, revealed himself as the source of leaked secret documents showing government surveillance of millions of Americans. From its origins as a management consulting firm, Booz Allen has quietly grown into a governmentwide contracting behemoth, fed by ballooning post-Sept. 11 intelligence budgets and Washington’s increasing reliance on outsourcing.
