V1 flew towards the island of Malta in an arc with a long tail in the air.

After a while, the correspondent shouted: "U928 report found that V1 was in good condition, with a speed of 350 and altitude of 300!"

At this time, V1 is still in the climbing stage and its speed and height are limited.

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

...

The launch point is 100 kilometers away from the target. If calculated based on the average speed of 500 kilometers per hour, the entire process only takes 12 minutes, which means that Dalei flew over a submarine every 3 minutes.

Feng Braun and others nervously calculated the missile's ballistics based on the data and orientation transmitted by the submarine... Although Feng Braun did not speak, Qin Chuan could tell from his face that the launch situation was not ideal.

As Qin Chuan expected, the original V1 missile could be said to have no accuracy at all. Its navigation system can indeed keep the missile flying in the air, and its direction is correct. The problem is that the target is one hundred kilometers away. The so-called "a slight mistake is a thousand miles away". As long as there is a little problem at the initial angle, or as long as there is a little airflow in the middle, it will eventually deviate from the target, and it will not deviate a little... The first V1 missile in history deviates from the target 24 kilometers. The subsequent V1 missiles are basically targetless and exploded. As long as they can be launched into the UK and landed on the ground and exploded.

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

This is almost an indiscriminate carpet bombing, which 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's off the schedule!" Von Braun replied.

Rommel glanced at Qin Chuan, and Qin Chuan nodded slightly.

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

Finally, the correspondent reported: "Two missiles exploded successfully on the island of Malta!"

The officers heard a lot of applause, but von Braun and Conrad looked very ugly because they knew that the missile did not hit the intended target, the airport on the island of Malta.

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

"No!" said Rommel. "We don't need to know what the hit is, we just need to know that it lands on the island of Malta, that's enough!"

Rommel said so, so the others nodded in agreement.

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

"Preliminary estimates that we have deviated from the target fifteen kilometers!" Braun said with his head pulling: "I know it may deviate from the target, but I didn't expect it to deviate from the target so far!"

After pausing, Braun continued: "Fifteen kilometers, which means we can't hit the target with it at all, 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 a little puzzled.

"It's very cheap!" Qin Chuan said: "It's easy to produce, I'm right!"

"Yes!" Braun replied: "Just build a few factories, two to three thousand can be produced in a month!"

"That's right!" Qin Chuan said: "This is what we need. We do not have air supremacy and cannot bomb the airports built by the Allied forces on the islands, but now we can... Yes, it does not have accuracy. One or two cannot hit the airport, but what if hundreds of them are shot at the same time? Or thousands of them are shot in a day?"

Von Braun's expression improved a lot when he heard this: "It's right, Captain, so it's still valuable!"

"Very valuable, professor!" Qin Chuan replied with certainty: "This is just the beginning, and its value will be far beyond your imagination in the future!"

"For example..." Feng Braun did not take Qin Chuan's words as a compliment.

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

"How can I 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 of all, we need to know its location and movement trajectory. Tracking with submarines like today is too inefficient on the one hand, and it will also put the submarine in danger on the other hand!"

"You're right, Captain!" Conrad replied: "But we have no other way!"

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

"We tried it!" Hannah replied, "But the 'target machine' is small and has a low height, so the radar cannot track it thirty kilometers away!"

"Hmm!" Qin Chuan nodded: "But I think you must have never tried installing a radio transmitter on the 'target machine'!"

Everyone was stunned when they heard this.

"Right, Captain, a good idea!" Von Braun's eyes couldn't help but lit up: "We just need to install a radio transmitter on the 'target machine' and let it send radio signals of a specified frequency to the radar so that we can track its location in time!"

"This idea is really great, Captain!" Hannah said, "Why didn't you tell us before?"

"Because before..." Qin Chuan replied in a pun: "I haven't seen it launch like I did just now!"

Speaking of this, Qin Chuan touched his chin and continued, "The moment I saw it launch, I suddenly had inspiration!"

Hannah couldn't help but laugh, with a blush on her face.

Braun and Conrad were a little confused, they didn't understand what Hannah was laughing at.

"Did we miss something?" Braun asked.

"No, of course not!" Hannah hurriedly stopped her smile, glared at Qin Chuan at the same time, and said, "You guys continue!"

"I think I know what to do!" Braun said: "If we master its position, we can constantly correct its trajectory through the radio, so that it can fly as much as possible on the predetermined trajectory, and finally make it hit the target!"

Qin Chuan nodded in agreement. This is what modern times calls "inertial navigation" or "inertial guidance". However, modern times inputs the target position and map data into the computer built-in missiles, and then the computer controls the missile to fly automatically to the target area.
