A group of U-2 spy planes, known for their work during the cold war, have been sent to Japan.
Three planes total, along with 180 new troops landed last week.
The “Dragon Lady” is a single jet, ultra high altitude spy plane used for intelligence gathering.
The reason for the deployment is simple: they are being used to collect data on North Korea and its nuclear program.
The United States is concerned that new ballistic missile tests in the Sea of Japan are signaling a possible nuclear test.
