Project cost: $395.7 billion
FY 2013 estimate: $9.4 billion
The radar-evading F-35 fighter jet is the most expensive weapon system in U.S. history. Designed as a stealthy fighter that can avoid radar detection, the F-35 is seven years behind schedule. The Pentagon estimates the cost for development and production of 2,443 F-35s will be $331.9 billion for the aircraft and $63.9 billion for the engines. That's a 70 percent increase since 2001, when the contracts were first signed with Lockheed Martin. “Putting the F-35 into production years before the first flight test was acquisition malpractice,” Frank Kendall, the Pentagon’s top weapons buyer, said in February 2012. “Now we're paying the price for being wrong about that,” he added.
