After a brief discussion, Mu Feng went to the temporary scientific research center that had just been built on the space island, opened a set of scientific research equipment, and began to study the reduced design of the export version of the sable.

First of all, in terms of appearance, the DSI air intake was canceled, and then the lines of the whole machine were repaired to be more rigid.

The plane looks better, but the performance is reduced, but the user can't tell from the outside.

The aerodynamic shape of a modern fighter jet is the optimal structure that has been accurately calculated by a computer.

To put it simply, I not only know that a place needs to protrude, but I also know all the detailed data such as the size and size of the specific protrusion, the shape and the radian, and so on.

Before the development of supporting technology in this era, they could only design directionally, only knowing that they wanted to protrude, but they didn't know the specific parameters, and they could only experiment one at a time.

It's a matter of luck for them to find the best design, and if they don't say it, they may never find it.

Then limit the search distance of the search radar and limit the range of air-to-air missile locks.

Limit the performance indicators of the fire control radar and limit the duration of the afterburner of the engine.

The types of ammunition carried are limited, and missiles can only be used with the products of their own command.

The engine uses an ordinary turbofan 13 and can reach a speed of Mach 1.6.

After setting the indicators, consume scientific research points to complete the scientific research plan.

This is a downgrading scheme, as long as there are no hard injuries after the downgrade, so the cost of scientific research is very low and almost negligible.

After the completion, Mufeng asked the headquarters to start producing the first batch of 220 sets.

Then the other export products were streamlined, including main guns, radars, and so on.

All the goods sold at the air show are produced in the manufacturing facilities of the local military ports, and all are airlifted to the southernmost military port on the island of Xiayue.

The equipment was loaded into the hangars of the two hulled escort aircraft carriers in the ship's state, and then the two of them set off from the airport in the Air Police 700 early warning aircraft.

Stop at the base of the space island, resupply and take off again.

The Air Police 700 has a maximum range of more than 6,000 kilometers, and can fly directly from the space island to the mainland of the USN, escorted by giant pandas with a maximum range of 6,000 kilometers.

Liaoning sent a modified aircraft carrier to pick up people outside the military port in the capital of the USN, and let the two escort aircraft carriers unfold their hulls on the dock.

Then Lanzhou and Taiyuan, with the order, delivered the goods on the spot with the traders who signed the contract.

…………

The USN envoy led by Saratoga sailed northwest after leaving Space Island.

Originally, they also wanted to release planes to reconnoiter the surrounding sea area, but soon found that every once in a while, jet fighters or propeller AWACS aircraft flew through the sky.

Saratoga thought of Kunlun's warning that all foreign planes were banned from flying, and finally did not try.

However, after two days of sailing, I did not encounter a single low-level deep sea at all.

Saratoga and his party gradually understood that this was due to the occasional passing planes.

Since they were able to sail safely all the way, they didn't look for trouble.

On the third day after leaving the space island, that is, the fourth day after Liaoning arrived on the USN mainland, and on the third day of the air show, the delegation finally entered the waters of the Northern Islands.

In the distance, a long, endless coastline appeared, and the sky began to see the occasional flying plane, from Silver Fox fighters to propeller AWACS aircraft.

At this moment, an air police 5 transformed from a giant panda came to the sky above the ocean transport ship of Saratoga and his party and sent a message by radio:

"Hello friends from USN, this is the Northern Islands, Commander of the Newport Task Force Qingyu, welcome to the PLAN Command, welcome to the Northern Islands.

"Please continue sailing in the current direction, and I will warn you in advance when you need to make a turn, and you will be able to reach Newport, the capital of the Northern Islands, about tomorrow evening."

Saratoga routinely replied:

"It's a pleasure to visit your headquarters, thank you for your pilot, keep in touch, and we'll see you tomorrow."

Saratoga established radio contact with Aoha, and then began to get several aircraft carriers, battleships, and cruisers to come out and spread their hulls on the sea.

The main purpose is not for fleet deterrence, but for direct observation of the surrounding environment with hull equipment.

After all, airplanes can't be used, I look at them with the hull, you can't help but let me see it.

In this way, the entire fleet continued to sail in a hull state, gradually approaching the shoreline of the sloping island that had appeared on the north-west skyline that had been seen earlier.

To stay on course is to sail along the coastline, which seems to have no end.

It wasn't surprising that there would be a large island on the mainland of the headquarters, but to Saratoga's surprise, there seemed to be no sign of human activity on the outside of the island.

In addition, there is a mountain range on the coast of the island, so you can't see the inside of the island from the outside, and you can only occasionally see various planes flying at high altitude.

Obviously, the other city's city and population are all on the other side of this mountain range.

This is the southeast coast of Shimogetsu Island.

I can't see it without a plane, but the other party doesn't let me use the plane, which feels quite aggrieved.

This state of affairs lasted until the evening, and the fleet had sailed more than five hundred kilometers, and Saratoga and the others finally saw the end of the island.

It is the eastern entrance strait of the Twin Moon Islands, which is only about 200 kilometers at its narrowest point, but nearly 300 kilometers deep.

The USN's envoys could not see the specific situation inside from the outside of the strait, but they could not turn to swim in the visiting fleet themselves.

The fleet could only keep the direction and continue to sail to the northwest, soon leaving the entrance to the strait.

Shangyue Island appeared, and the mountains on the coast completely blocked the view of Saratoga and the others.

Anyway, I looked forward to the day, but I didn't see anything.

On the other side of the fleet, a number of large and small islands were discovered one after another, but all of them were desert islands, and there was no sign of human life at all.

The fleet continued to sail until about ten o'clock in the evening, when, to the northeast of the fleet, an island again appeared, a large island without mountains on the coast.

At this time, Aoba's reconnaissance plane reappeared, reminding Saratoga and his party to adjust their voyage, and the fleet turned due north, which happened to follow the coastline of the islands that appeared in the east.

Saratoga's fleet was in good spirits again, and soon made observations all the way into the second half of the night.

Somewhat incredibly discovered, the island of the East is very large, at least 100,000 square kilometers.

But like the previous islands, there are no human settlements at all, and there are no towns at all along the coastline of five or six hundred kilometers, no matter how good the terrain is.

This is a primeval forest, and only on some hills there are a few observation radars.
