The decisive battle against the Third Reich

V1 flew towards Malta Island with a long tail in the air.

After a while, the communicator shouted: "U928 reported that V1 was found, the flight condition is good, the speed is 350, the altitude is 300!"

At this time, V1 was still in the climbing stage, and the speed and altitude were limited.

"U921 reported that the flight condition is good, the speed is 512 and the altitude is 530!"

...

The launch point is 100 kilometers away from the target. If calculated at an average speed of 500 kilometers per hour, the whole process only takes 12 minutes, which means that it will fly over a submarine every 3 minutes.

Von Braun and others nervously calculated the trajectory of the missile based on the data and direction transmitted by the submarine... Although von Braun did not speak, Qin Chuan could see from his face that the launch situation was not ideal.

This was within Qin Chuan's expectations. The original V1 missile had no accuracy at all. Its navigation system could indeed keep the missile flying in the air, and the direction was correct. The problem was that the target was 100 kilometers away. As the saying goes, "a small mistake can lead to a big mistake." As long as there was a little problem with the initial angle, or as long as there was a little airflow in the middle that changed the angle of the missile, it would eventually deviate from the target, and the deviation was not just a little bit... The first V1 missile in history deviated from the target by 24 kilometers. After that, the V1 missiles were basically randomly bombed without a target, as long as they could be launched to the UK and exploded on the ground.

However, because the Germans produced a large number of these cheap missiles, from the first missile launched to London in June 1944 to the surrender of Germany in May 1945, 20,000 to 30,000 missiles were produced in less than a year, of which about 10,000 were fired at the UK.

This was almost an indiscriminate carpet bombing, so it also caused great losses to the UK.

"What's wrong?" Conrad saw that von Braun's face was a little wrong, so he asked.

"It deviated from the predetermined orbit!" von Braun replied.

Rommel glanced at Qin Chuan, who nodded slightly.

Qin Chuan had reminded Rommel of this before, but this did not affect the strategic effect that Rommel and Qin Chuan hoped to achieve. All they wanted was for this thing to hit Malta.

Finally, the communicator reported: "Two missiles successfully exploded on Malta!"

The officers burst into fierce applause, but von Braun and Conrad looked very ugly, because they knew that the missile did not hit the intended target, which was the airport on Malta.

Just at this time, an officer asked: "Can we know what it hit?"

"No!" Rommel said: "We don't need to know what it hit, we just need to know that it landed on Malta, that's enough!"

Rommel said so, so the others nodded in agreement, and some even congratulated von Braun, Conrad and others, while the two dealt with it with very unnatural expressions.

Then Braun convened a meeting of scientific researchers, and Qin Chuan was of course among them.

"Preliminary estimates show that we are fifteen kilometers off target!" Braun said, hanging his head, "I knew it might be off target, but I didn't expect it to be so far off target!"

After a pause, Braun continued, "Fifteen kilometers, which means we can't hit the target with it, even if the target is an airport of several square kilometers!"

"Professor!" Qin Chuan comforted, "You don't need to worry too much about this!"

"Why?" Braun was puzzled.

"It's cheap!" Qin Chuan said, "It's also easy to produce. Am I right?"

"Yes!" Braun replied, "As long as a few factories are built, two to three thousand can be produced in a month!"

"That's right!" Qin Chuan said, "This is what we need. We don't have air superiority and can't bomb the airports built by the Allies on the islands, but now we can... Yes, it is indeed not accurate. One or two missiles can't hit the airport, but what if hundreds of them are fired at the same time? Or thousands of them in a day?"

Fon Braun's face improved a lot after hearing this: "You're right, Captain, so it is still valuable!"

"Very valuable, professor!" Qin Chuan answered with certainty: "This is just the beginning. In the future, its value will far exceed your imagination!"

"For example..." Von Braun didn't take Qin Chuan's words as a compliment.

"For example, we can improve its accuracy!" Qin Chuan replied.

"How can we do it?" Von Braun asked to the end, and Conrad also looked at Qin Chuan with interest.

"It's not difficult!" Qin Chuan said, "First we need to know its position and trajectory. Tracking with submarines like today is too inefficient and will put the submarine in danger!"

"You are right, Captain!" Conrad replied, "But we have no other way!"

"Why don't you use radar to track?" Qin Chuan asked.

"We tried!" Hannah said, "But the 'target drone' is small and low in altitude, and the radar can't track it at 30 kilometers!"

"Hmm!" Qin Chuan nodded, "But I think you must not have tried to install a radio transmitter on the 'target drone'!"

Everyone was stunned when they heard this.

"That's right, Captain, it's a great idea!" Von Braun's eyes lit up: "We just need to install a radio transmitter on the 'target plane' and let it send radio signals of a specified frequency to the radar all the time, so that we can track its position in time!" "This is a great idea, Captain!" Hannah said, "Why didn't you tell us before?" "Because before..." Qin Chuan answered with a pun: "I didn't see it launch like I did just now!" At this point, Qin Chuan touched his chin and continued, "The moment I saw it launch, I suddenly had an inspiration!" Hannah couldn't help laughing, and there was a blush on her face. Braun and Conrad were a little puzzled. They didn't understand what Hannah was laughing at. "Did we miss anything?" Braun asked. "No, of course not!" Hannah quickly stopped smiling, glared at Qin Chuan, and said, "You continue!" "I think I know what to do!" Braun said, "If we know its position, we can constantly correct its trajectory through radio, so that it can fly as far as possible along the predetermined trajectory, and finally hit the target area, so that the hit rate can be increased exponentially!" Qin Chuan nodded in agreement. This is the so-called radio guidance.
