Lockheed Martin, the maker of the F-35 fighter jet, has seen it's share price tumble as President-elect Trump has criticised the cost of the program.
During a press conference earlier today, Trump said he had been having talks with generals and admirals about bringing down the costs of the F-35 program.
The US Marine Fighter Attack F-35B Squadron has begun its worldwide deployment in Iwakuni, Japan.
The US military has described it as a significant step for the newly-developed aircraft, which only recently completed its final phases of testing.
It was announced in November 2012 that the Marine Corps would be introducing its first F-35B Lightning II Squadron.
What was previously a Hornet squadron has now been redesigned as the Corps' first operational F-35 squadron.
The first F-35Bs to be employed were a part of Exercise Steel Knight back in December 2015, during which they reportedly performed well.
This meant that in October 2016, a contingent of Marine Corps F-35Bs took part in final testing, showing that they could operate even in the most extreme sea conditions.
The squadron is now ready to make its big move from Arizona to Iwakuni in Japan.
The British military is set to acquire 138 of the aircraft around the year 2020, when the F35 Lightning II is introduced to the Royal Air Force and the Royal Navy.
