The sky is blue and the wind is cold.

"Call the tower, the sword squadron will carry out the transfer training mission, and request the formation to take off, over."

When everyone was ready on the runway, Yang Luo, as the squadron leader, called to the tower.

"The tower received, the ground wind direction is 265, the wind speed is 2 meters and seconds, the gust is 4 meters and seconds, there is no crosswind, the field pressure is 1009, and the sword squadron can take off in formation." In the communication channel, Wen Xianjun's voice suddenly sounded, "After taking off, adjust the frequency to xxxxx and contact the air command center to establish a route." May you have a safe journey and see you again in six months. ”

"The Sword Squadron received, ready to take off." Yang Luo replied, "Tower, see you in six months." ”

After obtaining the meteorological parameters and permission to take off, Yang Luo immediately ordered, "Everyone pay attention, the four planes take off in formation, and we go." ”

"304 received."

"305 received."

"311 received."

Release the brakes and push the throttle valve.

"Boom!"

The roar of the aero engines became louder and louder, and the four J-10Cs moved from static to mobile on the runway, and the taxiing speed on the runway changed from slow to fast.

Hasten!

More than ten seconds later, the four fighters took off into the air almost at the same moment, their slender fuselages like sharp swords, facing the blue sky.

After the four J-10Cs climbed to a thousand meters, they turned to the southwest in unison, anxious to continue climbing altitude.

"Call the command center, the Sword Squadron will carry out the transfer training mission, and request the establishment of a route to the Kat station, completed." During the climb, Yang Luo adjusted the communication frequency, connected to the confidential communication channel of the air division command center, and called the channel.

"The command center has received it, the route has been established and is being transmitted." In the communication channel, a familiar voice sounded in Yang Luo, "301, happy journey." ”

"Sword squadron received, thank you chief."

Looking at the route transmitted by the command center, Yang Luo was very helpless, it was another ultra-long-distance transfer flight, a total of 3,850 kilometers, and after adding three auxiliary fuel tanks, the aviation fuel was just right.

Click, send, and share the route with three other people via a data link.

"Attention all aircraft, climb to an altitude of 12,000 meters, fly along the designated route at a cruising speed of 950 kilometers per hour." Yang Luo said, "The transition distance this time is relatively far, it takes more than four hours, does anyone have a problem?" ”

"304 is fine." Xu Zhiqiang replied immediately.

Wang Hanyu followed up and replied, "There is no problem with 305." ”

The same is true for Xue Fei: "There is no problem with 311. ”

They have all been tested by ultra-long-distance flights, so naturally there are no big problems, and the flight range when handing over the J-7G and accepting the J-10C is even longer than this time.

This time, the J-10C did not have any weapons on it, but the internal fuel tank was full of fuel and three auxiliary fuel tanks were hung outside, but it still greatly reduced the maneuverability and flight performance of the J-10C, and the climb rate was also the same.

If they carry any weapons, they will not have enough fuel to reach the CAT station, and they will have to refuel in the air or land to refuel.

It took about 3 minutes for the four fighters of the Sword Squadron to climb to a predetermined altitude of 12,000 meters through the thin clouds in the middle and lower levels.

Heading southwest, the speed is 950 km/h.

Destination, Cat Field Station.

The roar of the aero engine resounded at an altitude of 10,000 meters, and four J-10Cs dragged four white trajectory clouds like silk, cutting through the sky, bathed in golden sunlight, and shuttling through the blue sky.

"Crazy, what's going on this time? How can you go to the training station of the CAT station that you have never heard of? Wearing an anti-load suit and a flight helmet, he controlled the fighter plane under him to fly smoothly above an altitude of 10,000 meters, Xue Fei asked through the encrypted communication channel.

Xue Fei was Yang Luo's wingman, so he flew on Yang Luo's right side.

Because the mission came so suddenly, there was not much communication with each other before.

Yang Luo smiled bitterly and replied, "Don't talk about you, I'm still confused." ”

"The previous training site of our regiment was either in Beita or in Anxian County, and we can be regarded as a precedent." Wang Hanyu on the far right said with a smile.

"The precedent is open, but the Kat station doesn't seem to be a good place, the station is small, the key is still in the deep mountains, far away from the people, and it is nearly 100 kilometers away from the nearest city." Xu Zhiqiang said a little depressed.

"Haha, it's no wonder, it's Xiaoqiang, you like to drill in the city the most, and every time you have a holiday, you don't see you." Xue Fei smiled, "Hey, Xiaoqiang, tell me what you do every time you go to the city?" ”

"Actually, it's nothing, it's just that I've been in the station for a long time and want to go out to breathe." Xu Zhiqiang said.

Xue Fei quipped, "The mountains and rivers near the Kat Field Station are good, you can breathe well." ”

"Well, yes, you can go around the mountains and hunt for some game or something." Wang Hanyu said with a smile.

Located on the edge of the Hengduan Mountains, the Kat Station is a station built deep in the mountains, and the scale of the station is relatively small, which can only accommodate the take-off and landing of a large group of fighters for maintenance.

There are so many wild animals in the vicinity that as long as they are not protected animals, no one will say anything about some game and tooth sacrifices.

Yang Luo didn't participate in their topic, his eyes were on the dashboard, and he seemed preoccupied.

Once he had his destination in mind, how to start training.

As the fuel continues to be consumed, time passes like flowing water, minute by minute.

The four fighters of the Sword Squadron flew over the vast plains in the northeast, crossed the rolling Yellow River and the Yangtze River, and enjoyed the majestic Qinling Mountains on the north-south dividing line.

After more than four hours of flying in formation, we finally approached the destination of this trip, the Kat Station.

Across the north and south, from the northeast to the southwest of the motherland, a distance of nearly 4,000 kilometers, bathed in the sunshine, appreciate the great rivers and mountains of the motherland.

"Are you almost at the Hengduan Mountains?"

Yang Luo's eyes were projected on the dashboard, determining his current position, muttering to himself, looking down, but he saw nothing, obscured by thick clouds.

The natural landscape of the southwest region, with an average altitude of more than 4,000 meters, is formed by countless mountain peaks, which cross the east and west.

The last time Yang Luo passed through the Hengduan Mountains was at night, and he didn't have a good view of the Hengduan Mountains, but this time he wanted to enjoy it.

It just so happens that they are about to reach their destination, and they begin to descend in height, which is more conducive to appreciation.

However, Yang Luo still didn't see anything.

At this time, the area of the Cat station was covered with dark clouds, sleet was falling, and the cloud cover was too low.

The three auxiliary fuel tanks attached to the four J-10Cs of the Sword Squadron have long been consumed, and the fuel in the internal fuel tanks has also been almost consumed, with less than 20 left, and the maneuverability has been restored.

Passing through the clouds, slowly reducing the altitude and speed, shuttling through the rain mixed with crystal snowflakes, facing the end of the trip, the CAT station.
