In general, lightweight materials were chosen for the creation of aircraft, and now, the Soviets actually used heavy stainless steel, solved a lot of problems, and finally created a cheap MiG-25.

And now, the MiG-25 no longer has any secrets in front of American experts, having been suppressed by the MiG-25 for so many years, they finally let out a long breath, this is just a backward aircraft, there is nothing to fear!

When this fear is removed, they can face the plane with a more high-spirited spirit.

At the same time, the real performance of this aircraft can only be determined through test flights.

After repeated verbal bickering, Nathan finally obtained this qualification and became the first pilot to fly the MiG-25.

Sitting in the cockpit, Nathan's mood was very calm, and the dashboard in front of him looked somewhat familiar, he had experience flying Soviet fighters in his previous life, and the instrument looked familiar.

With the ground power cart driven, the rear emitted a characteristic turbine whistling sound, and Nathan looked at the dashboard in front of him, and everything was normal.

"The Lone Ranger asks to take off." Nathan shouted over the radio.

"You can take off."

Nathan pushed the throttle stick, and the two R-15B-300 engines in the tail were blazing with blazing flames, already at maximum thrust.

Then, without hesitation, Nathan turned on the afterburner and released the brakes.

The thrust of the two engines is 220 kN, but its body is more bulky, and when it takes off with full fuel, the acceleration is not as good as that of the Tomcat.

With blazing flames, the MiG-25 began to slide on the runway, and the grass on both sides moved back quickly, and Nathan did not dare to hurry, until the back of the runway, he pulled up the operating lever.

After a few seconds of sliding, the landing gear behind it also left the ground and took off smoothly.

"Lone ranger, normal take-off posture." At this time, not far from Nathan, a black fighter plane was also accompanied.

The scene of the silver-white MiG-25 and the black SR-71 flying together is almost impossible to present, and now, the two planes flying side by side make people feel in a trance, as if the Soviet Union has collapsed, and the fighters of the East and the West will appear together.

"Now, I'm going to start climbing." Nathan shouted to the plane that was flying next to him.

Before taking off, someone suggested that this first test flight should simply not put the landing gear and go around the airport, but Nathan sternly refused, this is not a test flight of a new fighter, what are you afraid of! At Nathan's strong request, the first test flight began to examine various data of the MiG-25, such as climb rate and maximum speed.

Nathan turned off the afterburner, and the afterburner of the MiG-25's engine didn't know if it could be turned on for a long time, so it was better not to try.

The altimeter in front of him was slowly climbing, rising from a few thousand meters to 10,000 meters, and then to 20,000 meters.

Climbing again, I saw the edge of the atmosphere, and saw the arc outline of the earth, this scene always makes people feel very strange, as if they have come to outer space, and before I know it, Nathan has begun to indulge in this kind of scenery.

"Lone ranger, get ready to accelerate." Voices came from the headphones.

The next item is to test the speed!

"Understood." Nathan turned on the afterburner again.

Taking off and climbing, some of the fuel has been consumed, and the air is thin at high altitude, and the drag is very small, so this time when the afterburner is turned on, Nathan immediately feels the feeling of pushing back.

When he looked again, the blackbird was gone, and he was actually left behind.

This kind of steel fighter, once the fuel consumption leads to the reduction of the fuselage, is still quite good, and the benefits of a high-thrust engine are self-evident.

Nathan thought, watching the plane cross the sound barrier, barely seeing any sonic boom clouds, and continuing to fly forward, flying, the speedometer constantly turning.

"Lone Ranger, I'm amazed by your speed." The sound came from the headphones again, and Nathan turned his head to see that the Blackbird was finally following up.

At the beginning of the acceleration, the Blackbird was thrown behind, but the Blackbird's engine was also very powerful, and it quickly caught up.

The two sides are on par, continue to accelerate, accelerate.

When the speed exceeds Mach 2.5, the acceleration is slow, and the speedometer is slowly turning, 2.7, 2.8, and when it reaches 2.9, Nathan finally turns off the afterburner.

Although the MiG-25 is an aircraft that can fly up to Mach 3, if the engine is scrapped after one flight, I don't know how many people will scold themselves after going down.

At this time, the Blackbird had already thrown off the MiG-25 and flew to the front, compared to the MiG-25, the Blackbird could sprint to Mach 3.5.

"Acceleration ends, top speed 2.9, now return." Nathan shouted over the radio.

MiG-25, there are not too many secrets, this advanced fighter, in the eyes of the Americans, is already backward, but it shows the thinking of the Soviets, which is eye-opening.

With the wheels and runway in contact, Nathan returned to the surface and his brief life inside the Bill base came to an end.

"Rear Admiral Nathan, the top of the Navy is very happy to learn that you have agreed to come to England." On the plane to Portsmouth, Second Lieutenant Clive could not hide his excitement.

Ensign Clive flew once a few days after Nathan finished flying the MiG-25, and then, accompanied by Ensign Clive, Nathan and Emily embarked on this trip to Europe.

There was some surprise, Nathan couldn't wait to go back to fly Tomcat, in this era, except for Tomcat, he couldn't look down on other planes, but, for the Tomcat, he still decided to come to the UK once.

In the end, what made him decide to come was not Emily's so-called enjoyment of the two-person world, but because of the British ghosts mentioned by Ensign Clive.

Britain's own ghost, replaced with the British's own Spey engine, the performance is much higher than the J79 ghost, in this case, can the Tomcat get on Spey?

The problem of the Tomcat's engine should have been solved a long time ago, since the domestic advanced engine will be several years, Nasbei is installed on the Tomcat, which is also a temporary alternative.

The tomcat's heart problem had to be solved by Nathan.

Unconsciously, Nathan's fame began to grow, and the British Navy was complacent about inviting Nathan, and what Nathan didn't expect was that he was just a private trip, but he actually gained a lot.

And the secret of Nathan's life experience, after this trip, is also slowly emerging.

"Really?" "That's a real honor," Nathan said. ”

Nathan looked out the window, blue sky, white clouds, although the airliner was spacious, but he always felt uncomfortable, not as free as flying in the cramped cockpit of a fighter jet.

England, it's coming soon.
