This is the Soviet Far East, Primorsky Krai. Across the sea is the island nation, where the warm sea breeze blows, and the whole area is covered with dense forests, and the scenery is beautiful, and in the distance, the Ussurka River flows quietly.

Thinking of the terrible smog in the later life, the chaotic sky all day long, Andrei has a good impression of this place, although I don't know how to cross over, but, this place seems to be pretty good.

Already cruising at an altitude of eight thousand meters, through the cramped goggles, Andrey looked outside. Accustomed to the flying helmets of later generations, Andrei was very dissatisfied with the current helmets. The helmet of the later generations was a half-helmet, and the whole face was exposed, and after putting on an oxygen mask, the goggles were put down to cover the face. The current helmet is a full helmet, and when you put it on, there is only a small piece of space left in front of you to look out. However, the MiG-25 is a fighter that can fly to an altitude of 30,000 meters, even after attaching weapons, it can easily jump to 25,000 meters, which is already the edge of space, so it is necessary to wear this kind of helmet similar to that of an astronaut, and at the same time wear a high-altitude compensatory suit, otherwise, in case the plane really crashes and catapults from an altitude of more than 20,000 meters, the blood of the body will immediately steam.

However, the aircraft under the crotch is quite good, this is the pride of the Soviet military industry, the masterpiece of the Mikoyan Design Bureau, the world's first fighter that can reach double three! 30,000 meters in the air, Mach 3 speed!

At Mach 3 speeds, the temperature on the surface of the aircraft will reach hundreds of degrees, and ordinary aluminum alloys used to make fighter planes will also melt at this temperature! Therefore, in order to make such a high-speed flying machine, it is necessary to use special materials.

The idea of the Americans is to use high-temperature resistant titanium alloy, which is light and strong, while the idea of the Soviets is to apply stainless steel, which is common in the industry!

Yes, this is a fighter made of stainless steel! This is definitely a heavy fighter, with an empty weight of fifteen tons, a normal take-off weight of thirty-six tons, and a fuselage fuel load of up to sixteen tons!

Although Andrei of later generations had never piloted such a fighter, he was dismounted by the MiG-25 when he crossed over, and almost crashed. But now experiencing this kind of powerful fighter born from a simple and rough aesthetic, Andrei also has a faint excitement.

"031, 032, course 270, there is an unknown target in the sea area of the fourteenth, go to intercept it immediately! Cruise at Mach 2.4 speed. ”

Originally, Andrey's fighter broke down and should no longer carry out this kind of interception mission, but the two of them were in the right position to quickly reach the No. 14 sea area, so when the two of them returned home, they received such a task again.

"Roger." Belenko, the pilot of the long plane, replied: "The course is 270.The speed is 2.4."

Pressing the operating stick, the fighter drew an arc in the air and flew in the direction of ground guidance.

The standard interception tactics of the Soviet Territorial Defense Force were carried out under ground guidance, and Andrei followed his long plane, turning the slope and at the same time turning on the afterburner of the engine in the tail section to continue to increase his speed.

At this altitude, the air resistance is quite small, the tail of the two engines spew out a blazing tail flame, when the afterburner is turned on, there is an instant adrenaline to speed up the secretion of push back feeling, the R-15B-300 engine, burst out of 109 thousand N afterburner thrust, fuel injected into the afterburner, into high temperature and high pressure gas, pushing the fighter to continue to accelerate. A cone-shaped air flow appeared at the front end of the fighter, and then, the front of the fighter pierced this air flow, and in the gentle sonic boom, the fighter had entered supersonic cruise!

On the green dashboard, the hands of the Mach meter are slowly turning, Mach 1.2, Mach 1.5, Mach 2, and finally, it is stable at Mach 2.4!

With a slight throttle, Andre let the fighter fly steadily at Mach 2.4.

Two MiG-25 fighters, at a speed of Mach 2.4 and at an altitude of 24,000 meters, flew quickly towards the target area of 200 kilometers, a distance that only takes four minutes for the MiG-25! And an ordinary fighter, it takes at least ten minutes, and this is the advantage of an interceptor!

During the whole process, Andrey never turned off the afterburner from the beginning of takeoff, and was in afterburner flight all the time.

Ordinary fighters, such as the F-15 and other air superiority fighters, can only use afterburner during combat take-off and air combat, and the use of afterburner makes the duration of the afterburner only account for less than 10 percent of its flight time, and the afterburner cannot be used for more than three minutes each time, otherwise the engine will be damaged.

For a pure interceptor fighter, take the current MiG-25 as an example, in combat take-off, climbing, rushing to the war zone, air combat, etc., you can let the engine afterburner work to drive the aircraft. The afterburner was used for almost fifty percent of the entire flight time!

Otherwise, if the MiG-25 can only fly more than Mach 2 for a few minutes, then there is no real combat significance, the MiG-25 can fly Mach 2.4 when it can cruise indefinitely, until the fuel is exhausted, and when flying 2.83 to Mach 3.2, the engine may be scrapped, but not necessarily scrapped. Combat units can fly Mach 2.6 for 15 minutes during training, and more than Mach 2.83 is subject to regimental approval, while only the best pilots are allowed to fly beyond Mach 3.

However, flying with afterburner requires a lot of fuel, and in order to give the MiG-25 a longer supersonic range, the Soviets did it by increasing the amount of fuel! The MiG-25 has an in-flight oil storage of up to 16 tons!

Taking off from the base and conducting flight training, they have always been in a subsonic state, without turning on the afterburner, and now, after receiving the order, the remaining fuel in their fuselage has exceeded twelve tons, and this fuel is enough to support them to fly to the sea area of the fourteenth in a supersonic cruising state, complete the interception mission, and then return in a subsonic state!

Andrei's unit, stationed in the Far East, has the main task of supervising the US troops in the island countries across the sea and intercepting them at any time.

Every time, it's just an expulsion, but this time, with Andre who has crossed over, it is destined to be unusual!

Fast flight causes the body to rub against the air, and the cockpit canopy must not be touched with your hands at this time, otherwise the palm of your hand will be burned, although there is an air conditioning system in the cockpit, the temperature has risen to 50 degrees, which is definitely not a comfortable temperature, and all the pilots who fly the MiG-25 fighter say that it is acceptable!

Airplanes are for combat, not for pleasure, and the Soviet Union, which has never attached great importance to ergonomics, will not find anything wrong with this.
