This is the Soviet Far East and the coastal harbour. The island country is across the sea. The warm sea breeze blows, and the entire area is covered with dense forests and beautiful scenery. In the distance, the Usurka River flows quietly.

Thinking of the bad smog in later generations and the chaotic sky all day long, Andrei had some good feelings for this place. Although he didn't know how to travel through it, it seemed to be pretty good here.

He had already cruised at an altitude of 8,000 meters, and through the narrow goggles, Andre looked outside. He got used to the flying helmets of later generations, and Andre was very dissatisfied with the current helmets. The helmets of later generations were half helmets, and the whole face was exposed. After covering the oxygen mask, he put down the goggles to cover his face. The helmets of now are full helmets, and after putting them on, there was only a small piece of space left in front of them to look outward. However, the MiG-25 is a fighter that can fly to 30,000 meters at an altitude. Even after adding weapons, it can easily jump to 25,000 meters. It is already the edge of space. Therefore, you must wear this helmet similar to an astronaut and wear a high-altitude compensation suit. Otherwise, if the plane really crashes and ejects from an altitude of more than 20,000 meters, the blood in your body will immediately evaporate.

However, the plane under the crotch is quite good. This is the pride of the Soviet military industry, the masterpiece of the Migoyang Design Bureau, the world's first fighter jet that can reach double three! A height of 30,000 meters, a speed of three Mach!

At three Mach speeds, the temperature on the surface of the aircraft will be as high as several hundred degrees, and ordinary aluminum alloys used to make fighter jets will also melt at this temperature! Therefore, if you want to make such a high-speed aircraft, you must use special materials.

The Americans' solution was to use high-temperature resistant titanium alloys, which were both light and strong, while the Soviets' idea was to use stainless steel commonly used in the industry!

Yes, this is a fighter jet made of stainless steel! This is definitely a heavy fighter jet, with an empty weight of fifteen tons, a normal take-off weight of thirty-six tons, and a body oil carrying capacity of up to sixteen tons!

Although Andre had never driven this kind of fighter jet in later generations, and when he crossed over, he was attacked by the MiG-25 and almost broke down. But now, he felt a sense of excitement as he experienced the powerful fighter jet born from simple and crude aesthetics.

"031,032, heading 270, there is an unknown target in the No. 14 waters, go to intercept immediately! Mach 2.4 speed cruise."

Originally, Andre's fighter plane failed and should not have performed such an interception mission, but the two were in the right position and could quickly reach the No. 14 waters. So when they returned, they received such a mission.

"Received." The pilot of the chief aircraft, Berenko, replied: "Tail 270. Speed ​​2.4."

Pressing the operating rod, the fighter drew an arc in the air and flew towards the direction guided by the ground.

The Soviet National Air Defense Force, the standard interception tactics were carried out under the guidance of the ground. Andre followed his long aircraft, pressed the slope and turned on, and at the same time turned on the engine at the tail to increase his speed.

At this height, the air resistance is quite small. The two engines at the tail sprayed out a hot tail flame. When the afterburner was turned on, a feeling of pushing back that made adrenaline accelerate secretion appeared instantly. The R-15B-300 engine burst out with 109 thousand N afterburner thrust. Fuel injected into the afterburner combustion chamber and turned into a high-temperature and high-pressure gas, pushing the fighter to continue to accelerate. A conical airflow appeared at the front of the fighter, and then the front of the fighter pierced the airflow. With a gentle sonic boom, the fighter had entered supersonic cruise!

On the green dashboard, the Mach pointer is slowly turning, Mach 1.2, Mach 1.5, Mach 2, and finally, it stabilizes at Mach 2.4!

After a little retracting the throttle, Andre allowed the fighter to fly steadily at a speed of Mach 2.4.

Two MiG 25 fighters, at a speed of Mach 2.4, flew quickly towards the target area of ​​200 kilometers at an altitude of 24,000 meters. This distance only takes four minutes for MiG 25! And ordinary fighters take at least ten minutes, which is the advantage of interceptors!

During the entire process, Andre never closed the afterburner since the takeoff and was in the afterburner state.

Ordinary fighters, such as F-15, can only use after-force during combat takeoff and air combat. The time of after-force accounts for less than 10% of their flight time. Each time after-force cannot be used for more than three minutes, otherwise the engine will be damaged.

For pure interceptor fighter jets, take the current MiG25 for example. When fighting, taking off, climbing, running towards the war zone, air combat, etc., the engine can work hard to drive the aircraft. The time for use of afterburner reaches almost 50% of the entire flight time!

Otherwise, if the MiG 25 can only fly Mach 2 or more minutes, it has no practical significance. When the MiG 25 flies Mach 2.4, it can cruise indefinitely until the fuel is exhausted. When flying Mach 2.83 to Mach 3.2, the engine may be scrapped, but it is not necessarily scrapped. When flying Mach 2.6 during training, it can be allowed to fly Mach 2.83 during combat troops. More than 2.83 must be approved by regiment level, and only the best pilots will be approved to fly Mach 3.

However, using afterburners requires a lot of fuel to consume. In order to give the MiG-25 a longer supersonic range, the Soviets' approach was to increase the fuel volume! The MiG-25's internal oil storage capacity was as high as 16 tons!

Take off from the base and conduct flight training. They have always been in subsonic state and have not turned on the afterburner. Now, after receiving the order, the remaining oil in their bodies has exceeded 12 tons. This fuel is enough to support them to fly to the No. 14 waters in supersonic cruise state, complete the interception mission, and then return at subsonic state!

Andre's troops stationed in the Far East are mainly to supervise the US troops of the island countries across the sea and conduct interception operations at any time. They have performed such tasks many times.

Every time, it was just an expulsion, but this time, with Andre, who traveled through time, it was destined to be unusual!

Fast flight causes friction between the air and the air. The canopy cover must not be touched by hand at this time, otherwise the palm will be burned. Although there is an air conditioning system in the cabin, the temperature has risen to fifty degrees. This is definitely not a comfortable temperature. All pilots flying the MiG-25 fighter said it is acceptable!
