Before attending the meeting, Long Yun still had a concern, he didn't want to take the disk to the conference site to avoid complications.

After a little thought, while having lunch at a nearby restaurant, he quietly took out the disk in his pocket, stuffed it under the table and gave it to Lyudmila, saying nothing but winking at her.

Long Yun's idea was to let the completely reliable Lyudmila take the disk back first, so that nothing would go wrong later; The clever singer apparently understood what he meant at once, and she quietly stuffed the plastic bag with the disk in her handbag and smiled at him as she left the hotel.

Watching the car leave at the entrance of the hotel, Long Yun got into a station wagon specially sent by the KGB and headed to the PVO's theater command center on the outskirts of Moscow.

In the afternoon sun, two plain-looking grey wagons drive on the road leading to the outskirts of the city.

On the outskirts of Moscow, a nondescript suburban villa looks like a similar building all around it, but underneath it is a large-scale, well-connected PVO command center in the Moscow Theater of Operations.

Long Yun, who had come from afar, had passed through at least two highway checkpoints before entering the building, which were no different from ordinary police duty points, but were equipped with police dogs and mobile X-ray inspection vehicles, which were quite advanced at the time. Seeing these KGB agents dressed in police uniforms as a camouflage but with extremely alert eyes, Long Yun estimated that this should be a wartime inspection measure, because these roads leading to the PVO command center are usually impassable for various reasons, so there may not be any idle vehicles passing by.

Taking the elevator to the ground floor of the building, through the long corridor with bright lights, Long Yun looked around curiously as he walked forward, he had always thought that things like secret bases should be in film and television works, but he didn't expect that he could really see them in this parallel world.

Turning a corner and walking into a neat and spacious conference room with dim light, he found that there were already many people who looked like officers sitting at the long table inside, and after Long Yun greeted his colleagues present, he found a seat on the side of the long table near the door and sat down. As he walked past the attendees, he recognized one of the PVO officers who had greeted him at the Department of Defense reception, and the two men met their eyes and nodded to each other.

Seeing that everyone had arrived, the moderator cleared his throat and announced the opening of the meeting:

"Comrade Rezenov, first of all, I would like to remind you that the contents of this meeting are absolutely confidential, please pay attention to the confidentiality regulations."

Hearing the kind reminder of the host of the meeting, Long Yun nodded to show that he understood, he probably knew that the content of today's meeting was extraordinary. On the way here, he had been told by the accompanying PVO personnel that it seemed that he was going to be temporarily assigned to a special mission; But what exactly it is will be revealed only at the meeting.

"First of all, the topic of discussion today is the US reconnaissance aircraft that appeared in the airspace in the central part of our country: SR-71."

The officer on the task of explaining the task put the film on the slide projector, and a figure of an avant-garde black fighter plane appeared on the projection screen;

Hearing his straightforward words, Long Yun sat up straight in confusion.

SR-71, nicknamed "Blackbird" by NATO, has this aircraft not been mothballed and decommissioned by the Americans?

In the real world, the SR-71, which was extended from the A-12 project (CIA reconnaissance aircraft project), is a double-three (flight altitude of 30,000 meters, cruising speed of Mach 3) strategic reconnaissance aircraft developed by the US Lockheed Corporation in the 1960s.

In Long Yun's memory, the SR-71, a strategic reconnaissance aircraft with amazing flight speed and altitude, and at the same time high maintenance and use costs, although it has never been shot down in its decades of service, it is not a reconnaissance method that adapts to the development of the times; During the Cold War, when the two camps were facing each other, the Soviet air defense forces had not been seen since the last reconnaissance flight over the Soviet Union in 1981.

However, listening to the officer's explanation, and looking at the meeting materials distributed in front of him, he just realized that the situation in this parallel world was obviously very different from the real world.

In fact, since the outbreak of the East-West war, especially in the last half a month, SR-71 has repeatedly invaded the airspace of the Soviet Union, and each time the route has traversed a considerable span of space, which has had a great negative impact on the national defense security and war preparations of the Red Empire; Of course, for the sake of secrecy and to avoid unnecessary concerns, these situations are classified and have not yet been made public to the public.

The reason why the impact of the reconnaissance is strict is not that the SR-71 can really see a secret in the area where the route sweeps during the high-speed raid reconnaissance, but that it will make people worry or wonder what it has seen -- this uncertainty has brought a lot of trouble to the strategic decision-making of the Supreme Command.

Just as Long Yun was thinking, the officer continued to explain:

"According to intelligence sources, the invading SR-71s basically came from U.S. Air Force bases inside Pakistan. In terms of the planning of the reconnaissance route, our information is very complete, and it can be seen that there is no special pattern in it," the officer explained, changing the slide film, "The target has invaded the southern border of Central Asia, mainly the Republic of Turkmenistan, passed through the hinterland of Central Asia, and then turned back and escaped in the original direction, and the landing place is expected to be the same as the take-off location."

In previous interception operations, PVO aviation regiments stationed in Central Asia have sent a large number of fighters to participate; But unfortunately, due to the outstanding flight performance of the SR-71, it is difficult for conventional interception tactics to work against it, so nothing has been gained. Ground-to-air missile units, such as the S-300 missile system, are theoretically capable of attacking, but it is impossible for us to deploy mobile surface-to-air missile units on a large scale for the sake of one or two reconnaissance planes. ”

After listening to the officer's introduction, there was a brief silence in the conference room; In fact, the PVO personnel here basically know about these situations, and they mainly talk about it to Long Yun. After a while, Ivan Petrov, the commander-in-chief of the PVO, who had been silent before, opened his mouth, and his eyes kept looking at Long Yun as he spoke:

"That's probably the way it is. Comrade Rezenov, we have specially requested that you be called here just to entrust you with this difficult task: as the number one ace of the VVS, or, frankly, more than any pilot of the PVO, we hope that you will be able to participate in this matter and find a way to defeat the enemy so that the American reconnaissance planes will not dare to invade our airspace again.

――What are your thoughts on this mission? ”
