Lockheed Martin Aeronautics, a subdivision of Lockheed Martin, will be provided with $743 million in funds to modify the F-35 Lightning II fighters. This information has been disclosed by the Pentagon on the 18th of October, 2016.

The modifications to take place will also impact the price ceiling for F-35A and F-35B to be sold outside of the United States.

The United States Air Force (USAF) plans to procure a total of 1,763 F-35A in the coming years and to operate the largest F-35 fleet in the world. 10 other countries have already ordered the fighters: The United Kingdom, Australia, Norway, Italy, Turkey, Denmark, the Netherlands, Israel, South Korea and Japan.

The F-35A Lightning II fifth-generation fighter aircraft was declared "combat ready" by Gen. Hawk Carlisle, the commander of Air Combat Command.
