Lockheed Martin's F-35 jet, the most expensive weapons project ever, has received federal appropriations from Congress year after year despite a string of technical problems and repeated failures to deliver functioning planes on time and within budget. Just last week, the current F-35 fleet was grounded due to engine fires. The project is now expected to cost $396 billion by the time it is completed.

Lockheed Martin, maker of the F-35, has given $12.4 million to members of Congress (Senate and House of Representatives) from January 1, 2001 - December 31, 2013.

On July 17, 2014, by unanimous voice vote, Senate appropriators approved more funding for procurement of the F-35 for fiscal year 2015. The Department of Defense appropriations bill that includes the funds will now get a vote on the Senate floor.
