President-elect Donald Trump took aim Monday at a second US aerospace giant in as many weeks, this time attacking the F-35 stealth fighter and its "out of control" costs.
With a current development and acquisition price tag of $379 billion for a total of 2,443 F-35 aircraft -- most of them destined for the Air Force -- the Lockheed Martin-built plane is the most expensive in history, and costs are set to go higher still.

Trump has frequently turned to Twitter to vent his outrage across a range of topics.
On December 6, he blasted Boeing over the possible $4 billion price tag for a replacement Air Force One presidential plane. He also called that project "out of control."
Lockheed Martin stocks closed at $253.11 on Monday, down 2.47 percent. According to a Guardian report, this cost the company $4 billion at $28.6m per character tweeted by the president-elect.
Once servicing, maintenance and other costs for the F-35 are factored in over the aircraft's lifespan through 2070, overall program costs have been projected to rise to as much as $1.5 trillion.
But Lockheed insisted the F-35 program was "amazing" and said it would welcome the chance to answer any questions Trump may have.
The Pentagon declined to comment.
The US Air Force declared an initial squadron of F-35A fighters "battle ready," in August, after reports of cost overruns and delays. The Air Force's F-35A is one of three variants of the aircraft, designed to conduct conventional landings and take-offs.
Proponents tout the F-35's radar-dodging stealth technology, supersonic speeds, close air-support capabilities, airborne agility and a massive array of sensors giving pilots unparalleled access to information.
But the program has faced numerous setbacks, including a mysterious engine fire in 2014 that led commanders to ground planes until the problem could be resolved.
