The Soviet Union deployed a large air force in the Far East, although not as dense as in Western Europe, but definitely not a lot. After all, it was also a border zone between the USSR and the Western world.

Among them, the 8th Air Defense Army is responsible for the Komsomolsk air defense subdivision, and its troops are stationed in Komsomolsk-on-Amur, Khabarovsk, Soviet Port, Magadan and other places.

The 23rd Air Defense Army was stationed in Vladivostok, and the 513th Regiment to which Andrei belonged was a subordinate of the 23rd Air Defense Army.

On Sakhalin Island, the 24th Air Defense Division is stationed, which is responsible for not only Yuzhno-Sakhalinsk, but also Kunashir Island and Sawato Island.

In addition to these, there are the 25th Air Defense Division, stationed in the Chukotka Autonomous Region, the 29th Air Defense Division in the Amur Region, the 6th Air Defense Division of the Petropavlovsk Air Defense Division, and so on.

These are the deployments of the Territorial Defense Forces, and at the same time, in the whole of Sakhalin, the largest is the Kamenny Irukii base, which originally belonged to the territory of naval aviation.

The base is located on the western shore of the Tatar Strait on Sakhalin Island, across the sea from the island nation of Hokkaido. The 568th Naval Rocket Aviation Regiment and the 570th Naval Rocket Aviation Regiment stationed above are equipped with Tu-16 and Tu-142 large aircraft.

The 24th Division of the Territorial Defense Force, most of which was stationed at the Kaliukin base on the west coast of the Okhotsk Sea, originally had only the 308th and 777th regiments, equipped with MiG-21 fighter regiments and Su-15TM interceptors.

Now, the 308 has been replaced by the 41 regiment, because the 308 regiment is armed with the MiG-21, and the 41 regiment is armed with the MiG-23.

Although the MiG-21 is small and flexible, its body is limited, and it cannot even launch an over-the-horizon missile, so it is definitely a beaten cargo.

At the same time, the 592 Regiment was recently newly received, equipped with Su-15 interceptors, and the pilot who shot down the passenger plane, Osipovich, belonged to the 592nd Regiment and did great things less than a month after coming here.

But now, Osipovich does not regret it, although he hesitated at that time, but he will firmly carry out the advice of his superiors, and as long as the superiors give orders, he will still open fire bravely.

Even if it is a passenger plane that is shot down, even if he becomes a butcher who kills hundreds of people, he will still not waver, as long as he violates his own airspace, he must shoot it down.

Today, it is again Osipovich on combat readiness duty, sitting in the pilot's preparation room, silently looking at a large-scale map on the wall, and since the transition here, he has been studying the surrounding terrain almost every day.

For a pilot, memorizing landmarks is a basic task, and even in later life, with a global positioning system, the pilot must be able to figure out where he is in the conventional way, and not rely entirely on electronic devices.

So, it is quite important to remember the landmarks around.

There are mountains everywhere here, which peaks are how high they are, and the trend of the mountains, he looked at them very carefully, and at this moment, the air defense alarm sounded again on the airfield.

Quick, quick, there is a mission!

Osipovich picked up his helmet, rushed out with the wingman pilot, and ran towards his own fighter.

Hop on the plane, put on the helmet, turn on the radio, and the command briefing comes from inside.

A Tomcat fighter plane, which flew over Sakhalin, is now flying from Polonaysk in the middle of Sakhalin, in a southeasterly direction, and has already flown to the Terpenye Bay, the target flight altitude, fifty meters!

Osipovich frowned when he heard the last, this is not an easy task.

As a pilot of an interceptor, Osipovich is most skilled in flying towards the target under ground guidance and then intercepting it, but now, the target is flying at an altitude of only 50 meters, and the integrated air defense system cannot find the target at all, so it all depends on his own eyes.

Even the Typhoon-M radar in front of him does not dare to guarantee that the target can be found at such an altitude.

If only an AWACS aircraft could take off, it would be about the same.

But, as a warrior, where can you be afraid of difficulties! As long as there is an order, it must be on!

Osipovich expertly flipped the switches, started the engine with the help of the ground crew, and then taxied to the runway, took off, took off!

Two Su-15s, taking off in formation, it was now daytime, which was much easier than the night operation that day.

As an interceptor, the most important thing is speed, after the two planes took off, they began to climb high, accelerate, sprint to Mach 2.5, and go in the direction of the ground guidance.

The help of the ground is nothing more than that, guiding them to the sea area of the target, but the specific location of the target still depends on them to search.

The longer the time, the farther the goal goes, and if the bearing is wrong, there will be nothing to gain.

However, since the target is a Tomcat fighter, it will definitely fly to the US aircraft carrier battle group, that is, in the southern waters of the four northern islands, in the eastern part of Hokkaido, from Terpenier Bay, to the aircraft carrier battle group, draw a straight line, and fly north along the straight line, and it will definitely be able to intercept the other side!

This is also what ground guidance means.

The two planes extravagantly used afterburner at high altitude to try to get to the line quickly, and when they arrived, they began to reduce their altitude, and at the same time, the two turned on their own on-board radar.

On the screen, there are bright spots everywhere.

"Damn, radar doesn't work at all." Osipovich couldn't help but say.

In the air search, your own radar can still play a role, but the sea search is too pit, because the sea surface is full of ice floes!

Ice floes are more terrible than ocean waves, because ice floes are real objects, and they reflect back all the radar waves, because the radar has no ability to filter out, and now they are all white.

Without radar, you can only rely on visual sight!

Osipovich opened his eyes and carefully searched the sea surface, according to the usual training, it was enough for two planes to be responsible for ninety degrees each when searching the front hemisphere.

The Su-15 fighter slowed down and searched carefully on the surface of the sea.

Time, little by little, the hearts of the two of them, also gradually anxious, according to the speed of the voyage, at this time should have met, right, is it because the time has been long, dazzling, in the middle of a large group of ice floe, did not find out the target?

In the distance, the land could already be seen, which was the northern part of the Gulf of Terpenier, and it seemed that the target could not appear.

There was a hint of loss in Osipovich's heart, and at this moment, suddenly, an order came from inside the headset: "467, 468, immediately go to airspace 64, immediately go to airspace 64." ”

Hearing this voice, Osipovich was immediately filled with anger and actually ran over the ballistic missile silos!
