Investigation can only be carried out during the day.

The technical limitations of this era are that there is no infrared device, and it can only see everything on the ground during the day. Therefore, the Soviet aviation reconnaissance can only be achieved during the day.

In this way, they have to face a new problem.

The German reconnaissance planes were only discovered after flying over Moscow. This exposed the great flaws of the Soviet Air Force. They did not have long-range radar and other equipment and were defensively lagging behind.

But the Germans were not like this. The Germans had complete air defense facilities and various advanced reconnaissance radars. Therefore, if Soviet reconnaissance aircraft flew over in a big way, they would have to be knocked down in a few minutes. The German air force had been tempered into elite forces on the European battlefield.

So, how to complete the tasks assigned by Comrade Stalin?

The Germans rely on high-altitude reconnaissance and cannot reach any aircraft. At the same time, this type of aircraft has a terrible range and can only turn back when it reaches the Ural Mountains.

The Soviets need to investigate the military deployment of the Germans on the opposite border to see if they have large-scale military mobilizations. Therefore, the Soviets only need to dispatch small reconnaissance aircraft.

In this way, their choice is clear.

Wu-2 reconnaissance aircraft.

This aircraft is a multi-purpose biplane designed by the Soviet Polykapov Design Bureau, nicknamed "corn".

This aircraft, born in the late 1920s, is a simple biplane with an open two-cock cockpit. The body uses a pine skeleton and linen skin. The upper and lower wings are wired with wire. The power unit uses an m-11 air-cooled piston star 5-cylinder engine to drive a two-leaf wooden propeller with a power of 100 horsepower.

After production, this aircraft became a widely used aircraft due to its simple structure, low cost, easy production and maintenance, especially its excellent operating performance and outstanding take-off and landing performance.

It is almost a role of a panacea, capable of doing anything, reconnaissance aircraft, bombers, artillery school firing aircraft, transport aircraft, contact aircraft, etc., with huge output. Historically, in 1944, in order to commemorate the death of Polkapov, U-2 was renamed Bo-2.

Now, this aircraft is the most suitable reconnaissance aircraft for the Soviets. When it comes to the reason, it is ridiculous.

When the Germans compete in high-altitude highways, the Soviets can only take the low-altitude low-speed route.

Flying Captain Vladimir stepped into his cockpit. This kind of aircraft was like a toy. The open canopy cover made him wear thick clothes to drive. The weather is not warm now.

Behind him, Lieutenant Nicholas was also dressed in a thick leather hat, and at the same time checked the aerial camera installed on the side of the cockpit.

The camera is on the outside shelf, can be moved up and down, can be manually focused, and it depends entirely on the pilot's own operation. If it is not familiar with people, it will definitely be blurred.

The two of them had no pressure on this mission, it was like an ordinary flight.

"Start the engine!" Vladimir shouted to the ground crew.

This type of aircraft does not have an electric start function. The front crew turned the propeller twice with their hands, and black smoke burst out from the engine. The 100-horsepower engine started very easily.

Pushing the throttle rod, the plane finally returned to normal after emitting black smoke. Then, the plane began to slide on the lawn.

Yes, this kind of small plane does not require any runway at all, it only needs a small piece of flat grass to take off and land smoothly.

During World War II in history, when Germany occupied the western Soviet territory, those guerrillas that resisted the war relied on the Ukrainian-2 to transport supplies.

After sliding forward for dozens of meters, the plane easily pulled up. Vladimir operated the plane and flew at an altitude of about one hundred meters.

Flying forward for more than twenty kilometers, he crossed the border line and entered the German-controlled airspace.

The plane was flying at an ultra-low altitude without any obstruction. The first place he was going to was Shederce behind the Brest Fortress. If the Germans really prepared for a large-scale war, then there would definitely be a large force stationed in Shederce!

The plane is not fast, it is a boring voyage.

"Hey, Nikola, prepare our reconnaissance equipment and prepare to take pictures!" Vladimir shouted to his companion behind him.

"Okay." Nikola poked half of his body out of the cockpit, stared his eyes in the camera's observation hole, and began to carefully adjust the focal length.

In the camera, everything on the ground is so clear that if he wants, he can even see a gravel on the ground. The performance of a German camera is good!

In front of me is a barracks.

"Start take pictures!" Vladimir shouted.

The barracks were not empty, and you could see countless people shaking, and there were also guard posts outside.

"Click, click!" Nichola pressed the shutter and took photos.

Suddenly, he was stunned. In the square of the barracks, the things covered with camouflage nets looked like tanks!

"We seem to have discovered the situation." Nicholas murmured: "They have too many troops!"

If there is a radio on the plane, they can now report the situation. Unfortunately, this backward aircraft is not equipped with such communication equipment at all, so they cannot report what they find in time.

At the same time, the people below also discovered them.

Germany's warning radar has been working all the time, but even in later generations, advanced phased array radars will not easily detect a small aircraft flying at an ultra-low altitude, not to mention now, it is definitely a blind spot for the radar below 500 meters.

Therefore, the invading plane was only discovered now, and an alarm sounded in the base.

On one side of the base, several anti-aircraft artillery soldiers quickly ran towards their anti-aircraft artillery. Just as they were shaking the change direction, the reconnaissance plane had already flew away from the barracks in a daze.

The Soviet reconnaissance plane was discovered and entered its own airspace! The news was quickly reported. Almost a few minutes later, two FW190 fighter jets were already roaring.

Heinz Barr, the German ace pilot, happened to be his turn to patrol today. After receiving the news, he arrived immediately.

The fw190 has a good field of view, but it is always difficult to observe small targets on the ground, and the fuselage will block the view directly below.

Just while Heinz was still searching, his wingman Merritt had already visually discovered the target, shouted in the radio, and Merritt pushed the operating rod and rushed over.

"035, pay attention to the altitude and speed." Heinz shouted loudly, and he had already frowned. This interception mission seemed very difficult.
Chapter completed!
