D-12 was a Drone built to spy on China. The drone could fly as fast as the M- 21 The D-21 incorporated stealth technology. The motivation for the United States spying on China was the defense of our Nation. We needed to know what sort of ammunition they had. This was the Cold War we were preparing for World War III. a war that neither side wanted, but both sides prepared for.

We need to know where the Chinese were in their nuclear buildup. We discovered that the Chinese are testing, massive hydrogen bombs at a remote location in the Gobi Desert near the Mongolian-Chinese border.

M-21 Blackbird Aircraft

The Lockheed M-21 Blackbird is a unique variant of the A-12, the earliest Blackbird type (on the factory floor during A-12 production, two M-21s and three YF-12s were produced). Built for a CIA program code-named "Tagboard," the M-21 carried unpiloted Lockheed D-21 vehicles for intelligence gathering. These drones were intended for launch from the M-21 "mother ship" for flights over hostile territories.

The D-21 did indeed fly over China. One D 21 was found in Russian Siberia. A Soviet KGB agent gave Ben Rich part of a D-21. When Ben was traveling in Europe, the agent handed him a piece of the broken drone and asked him. “Do you recognize this?” This was about 15 years after the fact. The Russians had been analyzing a piece of the D 21, and they thought that was as far advanced as we could go. But they were wrong. Ben was delighted that they thought that was as advanced as the United States was in truth were far ahead of them both the Russians and the Chinese in our technology.

Design features of the M-21 include the second seat for the Launch Control Officer and the launch pylon on which the drone is mounted.

The sole surviving M-21 was built in 1963 and today is on display at the Museum of Flight in Seattle. In my opinion, this is the rarest of the Blackbird variations.

M-21 is just as fast as the A-12. The drone sits on the back of the M-21 when it is launched. M is for Mother. D is for Drone. MD 21 is a variation of the A- 12. Two were made, one crashed when the drone and the M-21 collided. The pilot and the RSO survived the ejection but unfortunately, the RSO Ray Torick lifted his face plate and drowned. This MD-21 can be seen at the Museum of Flight in Seattle, Washington. The Chinese have a D-21 on display at one of their museums. (See the last picture)

It is fascinating that this went on until 1971. That is when the Senior Bowl ended. It was ended by President Nixon because he wanted to go on a tour of China. He did go and they asked him to stop flying SR 71 over their country I assume they meant D-21s. The drones flew very fast… faster than an SR 71 and were picked up by radar.

The A-12s did fly very close to the border.

President Nixon promised that he would stop. As far as I know, they did stop. ~Linda Sheffield

But M-21's Fake name should be something Min Seojun or Min Seohyun.

민 Min- clever or sharp

서준 Seojun- auspicious and handsome

서현 Seohyun- virtuous and worthy

I'm getting this from

스물하나 seumulhana- twenty one

M (series name = surname)

21 (identification number = given name)

He's more likely to be called 21 by his family than M. Which means they're more likely to be overheard saying his designation. Giving people to assume his name is Seo.
