I saw where the F-35 gets one of it's most classified features, and it's amazing

Lockheed Martin"This room is the most advanced painting facility in the world," retired US Air Force pilot and F-35 simulation instructor Rick Royer told me as we toured Lockheed Martin's highly secure plane in Fort Worth, Texas.

The Aircraft Final Finishes bay is where America's most expensive weapons system gets coated with a highly classified stealth technology, which makes it invisible to radar.

After the jet is assembled and before it can take flight, three laser-guided robots apply the "Radar-Absorbing Material" (RAM) to each of Lockheed Martin's F-35 Lightning II variant aircrafts.

Here's all we know (and can share) about how the F-35 gets it's invisibility cloak:

Once an F-35 is ready to leave the production line, it is carefully rolled ...

... into the windowless, multistory, 226,000-square-foot Aircraft Final Finishes (AFF) complex.

The jet is placed in one of two paint bays where three laser-guided robots are programmed to spray RAM on all surfaces except the tails and various parts that are coated at a separate area called the Robotic Component Finishing System.

According to a SAE International report, the first coating process was completed on a F-35B in 2008 and took three days.

Currently Lockheed Martin's AFF facility services 7 aircrafts a month and is expected to increase to 17 jets by 2020.

NOW WATCH: We went inside a secret basement under Grand Central that was one of the biggest World War II targets
