Fifty kilometers from Alexandria, the Germans actually controlled the Zì line.

Many German warriors were parked on the soft ground of the alluvial plain of the Nile estuary with magic armor, and the unique leg skirt armor of this magic armor made it look quite bloated, and the whole shape was not at all related to the slender and elegant beautiful warriors. Just looking at the appearance, ordinary people will never believe that this thing is the Dom of Magic Armor for Desert Warfare (DOM), which is popular with war queens who are fighting in North Africa.

The ability to move on the ground air cushion at the expense of the jumping ability makes this mech quite good on flat surface, which may not be particularly useful in the face of Senhime, but the threat to Dom from firearms operated by ordinary people is greatly reduced.

The German warrior queens were already in position in the cockpit, and the voice of the captain of the warrior queen was transmitted to the ears of each warrior queen through the guò magic channel.

"This time, we are only responsible for cleaning up the mess, and the noble Goddess-sama will be responsible for breaking through the enemy's defenses and annihilating the enemy's living forces, and we will only face the trash fish that have slipped through the net." The captain paused, then continued, "I know that some of you are going to be nervous for the first time in battle. But don't worry, we old people are also rookies, there is nothing to be afraid of fighting, even if we are wounded, the enemy will not rush up to kill us, in this sense, as a war queen, the chance of surviving on the battlefield is much higher than those ordinary big-headed soldiers. ”

As soon as the captain's words fell, two flares rose into the sky.

"That's the signal to go, guys, it's time, start moving!"

Cunningham's flagship warweariness is leaving the port.

Cunningham himself was in the fleet command room of the Warweary, looking down at the report and other documents he had received when he boarded the ship this morning. At this time, the door of the headquarters opened, and the confidential officer entered the headquarters and reported in a loud voice: "The fluctuation of the enemy god has been detected and is approaching Alexandria." ”

"How many came?"

"Three, sir."

Cunningham pouted.

"Sure enough, the Prime Minister and Mr. President said that Lin Youde didn't take the time to confirm whether the Indians were cheating, this action is really simple."

"Yes sir, very crisply."

"Are all the garrisons in the city in place?"

"Yes, sir."

Cunningham's expression was a little sad, he sighed, stood up and went to the porthole of the command room, looking at the land that was moving away.

"The army will probably suffer heavy casualties this time."

The Anglo-American coalition's response to Lin Youde's possible attack on Shenji was simple: gather a fleet to break through the Strait of Connex, and then return to Alexandria, using the changed ratio of Shenji to launch a ground attack to recapture the port occupied by Lin Youde.

To accomplish this, tens of thousands of British and colonial troops defending Alexandria were scattered throughout Alexandria and the surrounding ring in order not to be killed by the gods, and then they were to fight in small groups throughout the city until the evening of the third day. After that, if the Anglo-American fleet had not yet appeared on the sea, they could have surrendered to the Germans "with all their glory."

Either way, though, the army is bound to suffer heavy casualties.

"I always feel a little uncomfortable." Cunningham whispered, "In the past, our Navy always laughed at the Army for not having a 'Royal' designation, but in reality, without the support of the Army, the Royal Navy alone would not be able to sustain this vast empire." Every time we threw the Army ashore as a gunman, we proudly claimed that the Royal Navy had once again protected the British Empire, which was somewhat unfair to the Army. ”

"Yes sir."

Cunningham glanced at the confidential officer, waved his hand slightly, and signaled that he could leave—presumably no matter what Cunningham said afterwards, the confidential officer was ready to answer with "yes sir."

When Cunningham was alone in the fleet command room, he looked at the porthole and pondered for a long time.

Mediterranean, Navy square N9.

The submarine U571 is conducting an underwater cruise at snorkel depth.

As a cutting-edge ship equipped with snorkel equipment and a simple oxygen chemical purification device, which can patrol underwater for a long time, the U571 has basically no results in the incident of joining the active service of the German Navy for more than half a year.

This is not due to the U571's poor crew skills and tactics, nor is it unlucky not to run into an enemy fleet during the cruise, but because the U571 has been training in the use of secret weapons.

Previously, the German scientific research department had used a self-guided mine to disrupt the British mine-sweeping operations in Lin Youde's offensive mine-laying, but soon the Navy's research department came to the conclusion that the self-guided mine effect was not as good as imagined from the damage report of the self-guided mine provided by Odin's Eye. After careful study, the scientific research department found that the crux of the problem lies in the guidance head of the self-guided mine.

All these self-guided weapons are based on electronic technology, and the current simple guidance devices made of bulky tubes are too clumsy, and the combat effectiveness of these weapons is very limited.

In fact, after a lot of practice, the German scientific research department believes that it is too difficult to manufacture automatic guided weapons with the current state of technology.

Therefore, they set the general direction as the remote control of the human brain.

However, the actual results of the 603 Technical Test Brigade have shown that the effect of remote-controlled bombs in actual combat is very bad. The main reason for this is that it is difficult to identify the location and body status of the bomb when the remote-controlled bomb is in use, and it is difficult to remotely control the bomb. Then the German scientific research institute turned to the research of horizontally flying rocket-boosted remote-controlled grenades, and the results achieved a good hit rate within a thousand meters, but no matter how far away, it was too difficult for human vision to track the small projectile body at a distance of more than a thousand meters, and even highly trained soldiers often lost their targets due to some interference.

However, the German scientific research institutes responsible for the research of guided weapons were not discouraged, and after rejecting a number of new schemes, they suddenly discovered that there was a scheme that could achieve artificial guidance under the current technical conditions.

This solution does not require the guide to have strong vision to capture a small projectile, and the use environment of the finished product of this program is relatively stable, so there is no need to worry about any strong external factors suddenly interfering with the movement of the projectile.

The solution is a human-controlled torpedo weapon.

The torpedo is a weapon that has several features when used.

First of all, the torpedo is a weapon that is aimed by means of calculation, and when carrying out a torpedo attack, the submarine commander needs to first use the ship identification manual to identify the target ship, and then obtain the length and mast height of the target ship through the manual, and then according to the height of the target mast, use the scale on the periscope to calculate the distance between the enemy ship and himself, and use the length of the target and the horizontal scale of the periscope to calculate the course of the target. The approximate velocity of the target is then further calculated by means of a stopwatch and periscope scale, as well as the calculated distance and course.

After calculating these, the fire control officer can plan out the firing parameters of the torpedo.

Contrary to many people's imagination, torpedoes in this era did not sail in a completely straight line after the launch tube was launched, and the fire control officer would generally set a deflection angle for the rudder behind the torpedo when launching, so that the submarine did not need to turn the hull to create a torpedo fan. When the fire control officer has set the parameters, the torpedo is ready to be fired, even if it is aiming.

With the high degree of training of the German army, the German submarine force could hit more than one torpedo in each salvo without evading the enemy ships -- it was unrealistic to hit all of them, after all, there were errors in these calculations, so they used torpedo fans to make up for the errors.

However, once the enemy detects the incoming torpedo attack and evades it, the hit rate of the torpedo will drop significantly.

Fortunately, the target of the torpedo was a large warship or transport ship. The maneuverability of large warships is actually quite limited. The main measure of the maneuverability of a large warship is the ratio of the diameter of the gyration to the length of the waterline. When the King George V is spinning at full speed, the ratio is 3. 74, the gyratory diameter reaches an astonishing 850 meters, and it takes about nine minutes to complete a 180-degree turn, and it takes about 17 seconds just to hit the rudder from the main rudder to the full rudder.

Therefore, the course of a large warship, which is the main target of a torpedo, can be predicted within a certain range. As for the transport ship, because it is a civilian ship, it pays more attention to economy than combat efficiency, so the rudder efficiency and speed itself are not as good as that of warships, and the tonnage is larger.

Because of this, the submarine can create a situation where "even if a torpedo is found", the submarine can create a situation in which "even if a torpedo is found".

One of the ways to do this is to fire a torpedo close enough that the periscope will be easily spotted. The main artillery shells of large warships are also quite a threat to submarines at periscope depth, and shells exploding in the water are like depth charges to submarines at periscope depth, and they are likely to shock something that should not be broken.

Another way to do this is to occupy an excellent firing position to geometrically reduce the chance of the enemy dodging the attack.

However, this method only reduces the chance of avoidance and increases the difficulty of avoidance.

As a result, Lin Youde's guided weapons research department proposed a third method: let the torpedo adjust its direction along with the maneuver of the large warship.

The maneuver of a large battleship is very sluggish, and it is completely possible to judge the change in the movement of the target ship through the guò periscope, and then adjust the course of the torpedo accordingly through the guò calculation.

Of course, this adjustment also requires knowing the current position and navigation state of the torpedo, and this is when the advantages of the torpedo are manifested - the torpedo is a slow-moving weapon, and the weapon pilot can very calmly draw its trajectory on the chart by the point of the compass on the torpedo and the speed measured by the simple speedometer carried by the torpedo.

Of course, there will be an error in this track, but the error value is basically negligible compared to the improvement in hit accuracy brought about by the innovation that the torpedo can change its course according to the change of the course of the enemy ship.

After arduous training, the U571 finally achieved a hit rate of four out of ten shots against a maneuvering target ship.

In the past, in order to achieve such a hit, German submarines had to occupy a very good position and be close enough to the enemy. Now, the U571 did not need such a position, in fact, they could theoretically occupy a position to launch from any direction of the enemy ship, and then send the torpedo to an excellent attack position with guò guidance.

Now, equipped with a brand new, sharp-fanged sea wolf, is lurking in the naval square N9, waiting for the arrival of its prey.
