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

After a while, the correspondent shouted: "U928 reports the discovery of V1, flying in good condition, speed 350 per hour, altitude 300!" ”

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

"U921 reports, flight condition is good, speed 512 per hour altitude 530!"

……

The launch point is 100 kilometers away from the target, and if the average speed is 500 kilometers per hour, the whole process only takes 12 minutes, that is, it flies over a submarine every 3 minutes.

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

This is in Qin Chuan's expectations, the original V1 missile can be said to have no accuracy at all, its navigation system can indeed keep the missile flying in the air, and the direction is also correct, the problem is that the target is 100 kilometers away, the so-called "miss a thousand miles", as long as there is a little problem with the initial angle, or as long as there is a little air flow in the middle to change the angle of the missile, it will eventually deviate from the target, and the deviation is not a little ...... The first V1 missile in history deviated from the target by 24 kilometers, and the subsequent V1 missiles were basically aimless and indiscriminately bombed, as long as they could be launched into the UK and exploded on the ground.

However, because of the large number of such cheap missiles produced by the Germans, from the launch of the first missile to London in June 1944 and the surrender of Germany 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 was almost indiscriminate carpet bombing, so it also caused a lot of damage to the British.

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

"It's off track!" 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 that this thing could hit the island of Malta.

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

The officers burst into loud applause, but von Braun and Conrad's faces were ugly, knowing that the missile had missed its intended target, which was the airfield on the island of Malta.

Just then an officer asked, "Can we know what it hit?" ”

"No!" Rommel said: "We don't need to know what hit, we just need to know that it fell on the island of Malta, and that's enough!" ”

Rommel said so, and everyone else nodded in agreement.

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

"According to preliminary estimates, we are fifteen kilometers away from the target!" Braun pulled his head and said, "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 that we can't hit the target with it at all, even if the target is an airfield of several square kilometers!" ”

"Professor!" Qin Chuan comforted: "You don't need to worry too much about this at all!" ”

"Why?" Braun was puzzled.

"It's cheap!" Qin Chuan said: "It's also easy to produce, I'm not wrong!" ”

"Yes!" Braun replied: "With just a few factories, we can produce 2,000 to 3,000 pieces a month!" ”

"That's right!" Qin Chuan said: "This is what we need, we do not have air supremacy, we cannot bomb the airfields built by the Allies on the islands, but now we can...... Yes, it's true that it doesn't have accuracy, one or two can't hit the airfield, but what if hundreds of them are hit at the same time? Or maybe you shoot thousands of them in a day? ”

Von Braun's face couldn't help but change a lot when he heard this: "That's right, Captain, so it's still valuable!" ”

"Valuable, Professor!" Qin Chuan replied with certainty: "This is just the beginning, and its value in the future will far exceed your imagination!" ”

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

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

"How?" Von Braun broke the clay pot and asked in the end, and Conrad also looked at Qin Chuan with interest.

"It's not that difficult!" Qin Chuan said: "First of all, we have to know its position and trajectory, as today's tracking with a submarine is too inefficient on the one hand, and on the other hand, it will put the submarine in danger!" ”

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

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

"We tried!" Hannah continued: "But the 'target aircraft' is small in size and low in altitude, and it cannot be tracked by radar at a distance of thirty kilometers!" ”

"Uh-huh!" Qin Chuan nodded: "But I don't think you guys have tried to install a radio transmitter on the 'target plane'!" ”

Hearing this, everyone couldn't help but be stunned.

"That's right, Captain, great idea!" Von Braun's eyes couldn't help but light up: "We just need to install a radio transmitter on the 'target aircraft' and let it always transmit radio signals of a specified frequency to the radar, so that we can track its position in a timely manner!" ”

"That's a great idea, Captain!" Hannah said, "Why didn't you tell us before?" ”

"Because I ...... before," Qin Chuan replied with a pun: "I didn't see it launch like I did just now!" ”

Speaking of this, Qin Chuan touched his chin, and then said: "The moment I saw it launched, I suddenly had inspiration!" ”

Hannah couldn't help but laugh "hehe", and there was a blush on her face.

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

"Did we miss something?" Braun asked.

"No, of course not!" Hannah hurriedly suppressed her smile, glared at Qin Chuan at the same time, and said, "You go on!" ”

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

Qin Chuan nodded in agreement, this is the so-called "inertial navigation" in modern times, but in modern times, the location and map data of the target are input into the computer built into the missile, and then the computer controls the missile to automatically fly to the target area.

Now it's just a matter of radar tracking and then human manipulation.
