The 2019 National Defense Authorization Act signed in August included 77 F-35 Lightning II jets for the Defense Department, but Congress decided to bump up that number in the defense spending bill finalized this week, for a total of 93 in the next fiscal year – 16 more than requested by the Pentagon. Here’s a look from Forbes at the evolving per unit cost of the stealth jet, which is expected to eventually fall to roughly $80 million when full-rate production begins in the next few years.
