When this scene was presented on the monitoring screen of the "Octopus" through various surveillance methods, both Temer and Valenio were stunned by the scene in front of them, especially Temer, whose head was buzzing.

When did a large country in the East have a new type of tanker?

A few years ago, they had just conducted a test experiment of air refueling, and the navy judged that this should be the main model of the future air tanker of a certain big country in the East.

Just as Temer was swiping the screen with various questions in his mind, the lieutenant colonel commander suddenly remembered something, quickly turned his chair to the side, rummaged through the filing cabinet, and then took out a clear silhouette photo of the Yun-15plus.

After looking at the slightly blurry real-time image of the Yun\\Oil-15 on the screen, and looking at the silhouette photo in his hand, he compared it repeatedly for more than a minute, and Temer suddenly exclaimed: "No...... No...... That's not the Y-15, definitely not the Y-15, but a completely new air transport platform, yes, that's right, definitely the latest air transport platform, we found the latest air transport platform of a large country in the East. ”

The last sentence of Temer was almost hoarse, and his abrupt cry immediately attracted everyone's attention, and Valenrio saw the screen and the hard photo for the first time because he was sitting next to Temer, who was close to the water.

The same was surprised to grow up the most.

The Y-15, which is being refueled in the air for two J-8 II, does look very similar to the Y-15plus, especially the fat-headed fish-like nose and sunglasses-like integral cockpit portholes, which indicate that this is an aircraft with deep roots in the Y-15plus.

If it is a different person who does not have a deep understanding of aviation equipment, it is estimated that when he sees this situation, he will really regard the Yun\\Oil-15 as an air refueling improvement model of the Yun-15plus.

But both Temer and Valenrio are senior officers, naturally they will not be as superficial as ordinary people, and it is precisely because of this that they will be shocked and unbelievable, the reason is very simple, the plane is undergoing air refueling operations, and it is very similar to the Yun 15 plus of the Yun \\ oil - 15 is actually not the Yun 15plus, but a brand new transport aircraft, the reason for this judgment is very simple, the Yun 15 plus is a twin-engine light transport aircraft, and the Yun \\ oil - 15 This is a four-engine medium transport aircraft.

In fact, the Y-15 is indeed a new air transport platform that is different from the Y-15plus.

But if you want to say that it is really out of the Yun 15plus, it is not necessarily, after all, the overall pneumatic layout and specific production situation are closely related to the Yun 15plus.

In Zhuang Jianye's words, Yun \\ oil -15 is the Yun 15plus fattening version, otherwise how can a new air transport platform still use the old name of Yun -15, in the final analysis, they are all branches derived from the same root.

You must know that when Tengfei Group developed the Y-15, it was not regarded as a product that was planned to be completed when the model landed, but left a strong room for upgrading and modification in the original design, especially in the later expansion, Tengfei Group was very humble to learn from the shameless ideas of Airbus and Boeing...... Bah...... It is the concept of modern development.

That is, you can expand and expand as much as you like on the basic model.

It's like Airbus's A320, shortened to become A318, elongated is A320-200, bold is A320-400, and the fully upgraded model is A320neo.

The same is true of the Ascendas Group's Y-15, which is more of a series than a model.

The twin-engine turboprop version is the base, and the twin-engine turbofan version is a transition, which can be freely extended in all directions based on these two models.

For example, the Yun\\Oil-15 was actually not built by the Tengfei Group alone for fun, but was tailored according to the Air Force Headquarters' explanation of the bidding for air tankers.

At first, the Air Headquarters did not take the bidding plan of the Ascendas Group seriously, because at that time, the Air Force was interested in the Northwest Aviation Plant's Bomber 6.

This air tanker is based on the H-6 bomber, and the idea is similar to that of the Soviet Union using the Tu-16 bomber to modify the Tu-16N air tanker.

Not only is the platform mature and the production process guaranteed, but the training and maintenance are also not complicated, which is very in line with the current domestic reality.

In addition, as early as 1991, the bombardment 6 was tested with the Jian-8 II for aerial refueling, and the overall performance was extremely good, so it has always been a key project supported by the Air Force.

Now that the Air Force is satisfied, what are you looking for Tengfei Group for?

The problem is that with the deepening of reform, the state's large-scale procurement will have to engage in competition and bidding, and the troops will naturally respond to the state's call and make a show.

Therefore, a tender was sent to the domestic aviation enterprises that are "capable" to produce air transport platforms, and the deadline was one year to come up with their own bidding products.

Just looking at this bidding requirement, we can see that the Air Force Headquarters is obviously biased in favor of the Northwest Plant, because their H-6 has been flying for more than a year, and it seems that the first phase of the test flight test is about to be completed, and even if other factories fold their waists, it is impossible for them to come up with products as mature as H-6 within a year.

Know that it's an airplane, not a kid's building block toy.

Therefore, the named aviation plant is basically to hand over a drawing to make soy sauce with peace of mind, and the only one that is considered by the industry to have hope to compete with the bombardment 6 is the Yun 8, because it is the same as the Northwest Aviation Plant, so there is no positive PK relationship.

As a result, just when people thought that the bombing 6 would win the Air Force's 26 orders without any suspense, the Air Force Flight Test Verification Center suddenly came to the news that Tengfei Group's new medium-sized air transport platform began to conduct full-scale ground static tests.

As soon as the news came out, the industry was in an uproar: What is the situation? Why did the Tengfei Group come up with a new medium-sized transport plane? Why did they come up so fast? When did the Tengfei Group launch the new Zhongyun? Why didn't there be any rumors in the industry?

Just when the industry did not have time to digest how Tengfei Group began to develop the new Zhongyun, three months later, the Air Force Flight Test Verification Center once again reported that Tengfei Group's new medium-sized transport aircraft Y-15MAX made its first successful flight.

Immediately after that, news began to spread in the industry, and the Y-15MAX also unveiled its mystery in this spread.

The Y-15MAX is an improved upgrade of the Y-15plus.

The overall proportion has increased significantly with the Y-15plus, and the multi-task capability has been enhanced several times compared with the Y-15plus, especially the cargo compartment can be added to four aviation fuel storage modules developed by the Tengfei Group, plus the Y-15MAX itself has four large fuel tanks and two small spare fuel tanks, making the maximum fuel carrying capacity of the Y-15MAX reach 30.7 tons.

It is also capable of delivering 18.2 tons of aviation fuel to various types of aircraft that need to be refueled.
