At the same time, Chang Haonan was busy for the two projects of Air Police 200 and Turbofan 10.

Tehran, Mehrabad International Airport.

An Il-76TD transport aircraft painted in the rather strange Soviet civil aviation livery for this era is preparing for landing in a rather classic "maximum gradient landing" attitude.

This modality requires the pilot to aim the aircraft at the runway in a swooping attitude and level the aircraft at the last minute before touching the ground.

It's a great test of courage and skill.

A few minutes later, the Il-76 came to a smooth stop at the end of the runway, where quite a few people and two trucks were already there, apparently having been waiting for a long time.

Yang Jin, an engineer from Factory 112, walked forward quickly with the staff behind him, ready to unload the goods.

The huge three-lobed tailgate slowly opens.

The scene in the cargo hold made Yang Jin, who saw Il-76 for the first time, feel a little shocked.

A full six turbojet-14 engines were flown in from Shengjing.

Although the Turbojet 14 is a very small engine in size and weight, in order to ensure that the transportation process is foolproof, the 410 factory is often packed in a very exaggerated box before installation.

The previous first batch of 4 engines were all transported by Yun-8, and only two could be transported at a time, and the cargo hold volume was still tight.

Several people jumped down from the huge gangplank door, and the first one came to Yang Jin and shook hands with him, and then said in a slightly anxious tone:

"This is the second batch of six engines, move quickly, there will be another plane coming over a little later."

"And six engines?"

Yang Jin was a little incredulous.

As a technician of Factory 112, he is still clear about the ability of Factory 410, a brother unit.

In the previous six months, a total of 4 units were delivered.

After all, the Turbojet 14 model is used everywhere, and it is impossible to give them all of them.

"No, there are some other aircraft materials in the back, and radar."

It wasn't until a group of people began to unload the cargo with the assistance of the tail crane that the other party breathed a sigh of relief and introduced himself:

"Comrade Yang Jin, my name is Han Linping, from Factory 410, and I am responsible for docking with the ghost reform project in Persia."

"Hello, but it's not always Lin ...... before"

"Lao Lin was transferred to be in charge of the logistics support of key model projects, so I came to replace him."

Han Linping explained.

Yang Jin was stunned when he heard this, he had followed the foreign team set up in the factory to Persia half a year ago, and he had not returned to China since then, so he was very closed to the news in this regard.

However, he also knew that this was definitely not the occasion to discuss confidential topics, so he had to suppress his curiosity:

"That's a great cooperation."

"It's a pleasure to work with."

As Han Linping said, about twenty minutes later, another Il-76TD with the same livery landed in the same wild fashion, bringing with it other parts involved in the improvement project.

"These Il-76s that you rented from Lao Maozi?"

After unloading all the aviation materials and loading the car, Yang Jin, who was a little out of breath, found Han Linping.

He was really impressed by these two huge planes.

"No, I bought a few finished planes from the Tashkent factory a few months ago, and I didn't have time to change the livery, and the superiors considered that it would be a little confusing, so they used it for the time being."

Han Linping, who had just taken off his gloves, shook his head and explained as he looked at Il 76, who was being prepared in the distance.

At this moment, a Land Rover off-road vehicle stopped in front of the two.

"Let's get in the car first"

Yang Jin opened the car door and motioned for the other party to sit down.

In fact, Mehrabad International Airport, as a dual-use airport with a large passenger flow, is not well suited to undertake such a sensitive military transport task.

Even the Persians themselves know this, so preparations are underway for the construction of a new Imam Khomeini International Airport.

However, construction has only just begun, and it is far from being completed.

The reason why it is necessary to use it is because the Persian Aircraft Industry Corporation (IACI), the only company in Persia that has the technical ability to maintain the F4 and F14 fighters, is located right next to it.

It even shares one of the runways with Mehrabad International Airport.

If you land somewhere else and then transport it by truck, not only will it cause more movement, but there will also be other risks along the way.

In the end, you can only choose to carry out the transportation task in the evening or early morning when there is less passenger flow.

Fortunately, after changing from the Y-8 to the Il-76, the number of sorties required will be much less.

"How's our retrofit progressing now?"

After looking at the rapidly receding scenery outside the window for a while, Han Linping quickly felt a little monotonous, so he turned around and asked about the project.

"The first two upgraded aircraft have been delivered, and now we are just waiting for your engines to start working again."

Speaking of this, Yang Jin couldn't help but show a smile:

"Seriously, you should have come a month earlier and heard what the Persians had to say about the two new engines we put up......"

As the two spoke, an F4 fighter jet painted in blue-gray livery roared and took off from another runway not far away.

"Well, that's one of the planes we've changed, the Persians renamed it F4EC, and they also changed the livery."

……

Lieutenant Colonel Siawash Bayani and Captain Sania Hoda were sitting in the cabin of the F4 that had just taken off, heading northwest.

The radar station there reported several unusual approaches of the Turkish Air Force.

Since the Persian Air Force has been plagued by the problem of aircraft availability since the Iran-Iraq War, it generally does not respond to such actions by its neighbors.

Moreover, Tehran is more than 400 kilometers away from the border between the two countries, and most of the time it is simply too late.

But one of the other side's targets seems to be particularly persistent today, lingering several times around the province of West Azerbaijan and repeatedly showing that it wants to cross the border.

Then I had to go and see it.

After quickly climbing to a predetermined altitude of 12,000 meters, Lieutenant Colonel Bayani pushed the throttle valve to the end and opened the afterburner.

The number on the aircraft's airspeed meter skyrocketed, quickly breaking through the speed of sound.

As the ace who shot down the Mirage F1, Su-20 and MiG-25, the 40-year-old Bayani is almost the most experienced pilot in the entire Persian Air Force to fly the F4.

But after being transferred to the TFB1 base and refurbished with this new aircraft, he even began to doubt his nearly 2,000 hours of flying experience in the past.

Although the sea-level thrust of the Turbojet 14 is about 7% lower than that of the J79, the dry weight is almost 60% of the latter, resulting in an even higher thrust-to-weight ratio of the aircraft after thrust reduction and trim.

However, this is not a big problem, and the most uncomfortable thing for him is actually the difference in feel caused by the improvement of power feedback speed.

In the past, the F4 would have a rather slow ramp up after the throttle valve had acted, causing Bayani, who had developed a habit, to feel like he was behaving like an Alzheimer's in the first dozen hours of the plane.

Always half a beat slower than an airplane.

He hadn't felt this way since his second year of flight school.

However, after becoming familiar with the new rules of manipulation, he quickly forgot all the unpleasantness during the run-in period.

Bayani must admit that before that, he definitely looked down on Huaxia equipment.

In that protracted war, due to the huge consumption and the increasingly empty treasury, both countries coincidentally purchased a large number of weapons produced in China.

But is it a good experience......

The saying of high emotional intelligence is probably that the cost performance is relatively high.

However, this fighter plane that was changed by the Chinese made him look better.

To put it simply, it's cool.

At least in the past, when using the J79, he would never dare to turn on the afterburner so unscrupulously.

"Lieutenant colonel, the radar found a target at a distance of 90, an altitude of 10000, a speed of 970, and a course of 110."

Hoda in the back seat reported.

In fact, this process was not necessary on this plane, because the HUD in front of Bayani in the front seat also displayed almost all the target information synchronously.

But other than that, he really didn't know what he could do.

In the past, on the F4E, because the radar operation was quite complicated, a second pilot in the back seat was set up to be responsible for this business.

However, after the Huaxia people upgraded the radar, the meaning of his existence as a weapon control officer was completely erased.

But the Persian Air Force didn't have time to adjust with it, so he still had to take off again and again, and then watch Lieutenant Colonel Bayani perform in front.

"I saw it, it should be a goblin, but the other party shouldn't have noticed us yet."

This new radar with superior performance is also one of Bayani's favorite spots.

The fly in the ointment is that the Thunderbolt-11 missiles sold in the matching match are half a pound or two with the Sparrow, and even if they shoot head-on, they only have an attack range of about 30km, which completely wastes the performance of the radar.

The mission didn't get permission to use weapons first, but that didn't stop Bayani from doing some of the things he wanted to do.

For example, switch the working mode of the radar.

Although he hasn't been able to really lock on to the target yet.

The other side obviously felt the ill-intentioned radar signal, but at this distance, it was obvious that the old radar like the AN/APG59 could not see what was happening.

The two sides still maintained their head-to-head direction, but Bayani could assure that fear had begun to grow in the hearts of the opposing pilots.

Just like when he was locked on by a MiG-25 during his first take-off many years ago.

And even when he actually went into visual distance, he didn't panic at all.

When the sun rises in the morning, the side to the east has a natural advantage.

The opposing pilots will be shaken by the morning sun and it will be difficult to see the target clearly.

Bayani had just praised the opposing pilots for their courage and was ready to let the backseat pilots keep an eye on their surroundings – the only role ballast could play in air combat.

"Captain, watch ......"

However, halfway through the conversation, the F4 was defeated in this psychological confrontation, made a 180-degree steep turn, and accelerated away from the border.

Although, according to the experience of the lieutenant colonel, the opponent only needs to fly for another 5 to 6 seconds before he can clearly see that he is facing an "identical" Phantom fighter.

"Notice what?"

Hoda in the back seat asked suspiciously.

"It's nothing, pay attention in the future, you must not be as timid as them."

Bayani shook his head:

"If this is an air battle, the other side still has a 30% chance of winning, but now it is certain to die."
