The supply of the fleet is not something that can be solved by touching the skin of the mouth, and the shells consumed by the electromagnetic cannon alone are an astronomical amount, and at least tens of thousands of tons of metal are needed to fill this huge hole.

There is no shortage of metal ore in Yunzhou Star, but the expansion of the fleet headquarters requires a large amount of metal, and the extrusion of more than 10,000 tons of metal will inevitably affect the construction progress of the space base.

The armies of robots in various mines have long been running at full capacity twenty-four hours a day, but there are many places where Yunzhou Star needs metal materials, including the expansion of fleet bases, the construction of satellite factories, the construction of new warships, etc., all need a large number of metal materials, although the amount of ore mining is very large, the consumption can exceed the mining volume!

Duan Ping, who was reappointed as the head of the fleet's logistics department after the establishment of the advance fleet, almost turned gray because of this incident, and he demolished the east wall to make up for the west wall, and even had to stop the construction of the satellite factory for two days before he could get the shells that the fleet needed.

Nowadays, the shells of the electromagnetic cannon are no longer the standard model, because the battleship must use shells of different qualities according to the different mission conditions, for example, the thickness and density of the atmosphere of the two planets Yunzhou and Huzhou have a certain difference, and the shells of the same volume and mass, if used on planets with thin atmospheres, the power is equivalent to 100 kilograms of TNT, and when used on planets with thick atmospheres, they may burn up in the atmosphere before they touch the ground.

Therefore, the logistics department provided the battleship with no longer formed shells, but cylindrical metal rods with a diameter of about ten centimeters, which needed to be divided on the spot according to the target situation when used, so as to facilitate the control of the power intensity of the shells when they hit the ground.

Compared to the Aquila-class electromagnetic cannon. The recipe for the gravity gun is obviously much broader, and any hard, heat-resistant substance other than metal can be used as a cannonball after being processed and formed.

For example, granite is good, or simply pour a batch of reinforced concrete, and anything that can be stuffed into the barrel of a cannon can be fired, even if a person climbs into it.

Of course, if you really use people as cannonballs, I'm afraid that before you can fly out of the barrel, you will be completely crushed into a mess by the ultra-high acceleration.

The electromagnetic cannon and the gravity cannon are completely two extremes, and it is not better than not knowing one and being frightened. The logistics department loved the gravity cannon to death. For this reason, they actually jointly proposed that the fleet use gravity guns to replace the electromagnetic cannons on all Skyhawk-class warships!

The advanced part of the gravity gun is the design concept rather than the power, under the same quality, the muzzle velocity of the shell fired by the electromagnetic cannon with the mouth is higher than that of the heavy gun, but the main task of both the electromagnetic gun and the gravity gun is ground attack rather than air combat. This difference in power is really nothing.

It's just that Yunzhou Star's satellite factory has not yet been completed. Ye Fei, who received the construction of Yì, had no plan to replace the gravity cannon for the Sky Eagle class. Second, for the time being, there is no ability to replace gravity guns for warships -- the barrels of both electromagnetic guns and gravity guns are basically large weapons that run through the entire ship, and to replace such a large piece of equipment, the shell of the battleship must be dismantled in a satellite factory. Certain adjustments to the internal structure of the battleship also had to be made.

Renovating warships is sometimes more troublesome than building warships, and even if the satellite factory of Yunzhou Star has been put into use, such a large project will not be completed in a while.

In order to speed up the fleet repair, Ye Fei had to order half of the warships to fly to Huzhou Star, so that the space base that originally belonged to the Huzhou fleet could share the pressure of fleet repair.

After arranging all the arrangements, it was already two days after the fleet returned to the Yunzhou Galaxy, and as soon as Ye Fei, who was finally relieved, was idle, Duan Ping mysteriously came to the door: "Commander, I have good news." ”

"What's the good news?" Ye Fei, who was rarely idle, made a gesture to Duan Ping, motioning for him to sit down opposite him, "What to drink?" ”

"Tea is fine." Duan Ping said.

"Xiao Liu—" Ye Fei raised his voice and shouted.

"Here!" Orderly Xiao Liu immediately ran into Ye Fei's office, "Commander, you called me." ”

Orderly Xiao Liu is only seventeen years old, with clear eyebrows and beautiful eyes, and is one of the clones recruited from Yunzhou Star during the time when the God of War flew to the base star.

At present, the total number of clones like Xiao Liu serving the fleet has reached more than 3,000 people, and they are basically arranged in some non-combat positions that are not very important.

Duan Ping planned to select some of the clones with stronger physique to supplement the commandos in the next step to make up for the losses in this battle.

Ye Fei waved at Xiao Liu: "Pour two cups of tea." ”

"Yes!" The orderlies immediately ran out in a rage.

"Tell me, what's the news?" Ye Fei slumped into the chair and asked lazily.

Duan Ping's time to Yunzhou Star is not short, because Ye Fei has been floating outside with the fleet, and they don't have much time to get along, but Duan Ping is very kind of Ye Fei's temper, and their relationship is quite close, so Ye Fei never puts any commander's stinky shelf in front of Duan Ping.

"Good news, of course." Duan Ping sold it slightly, "I got a little bit of information during this time, maybe you can use it." ”

"Intelligence?" Ye Fei was so surprised, his surprised mood directly led him to make a strange expression with one eye big and one eye small.

"Yes, intelligence!" Duan Ping nodded heavily, not at all like a joke.

"No, what are you doing?" Ye Fei's face was incredulous, "I fought to the death in front, I almost didn't throw all the commandos on YM174, and I didn't get any information, where did you get the situation?" Don't tell me that it's Yankee or Russians, and I'm not interested in that. ”

Duan Ping's shoulders suddenly collapsed: "I don't have anything wrong with my brain, how can I fool you with those useless things, Commander Ye?" You don't look at people in the cracks. ”

"That's weird." Ye Fei spread his hands, "You haven't left Yunzhou Star during this time, except for the news of the colony stars in the United States, Russia and Europe, I can't think of any other information that you can get that can be regarded as intelligence...... I'm sure I've heard about the base star earlier than you know! ”

Except for the confidential department, any news from the base star will be the first to notify Ye Fei, the fleet commander, and without going through his hands, the officers below want to get any news from the base star.

"Haha, it's all wrong!" Duan Ping laughed smugly, "I knew you wouldn't guess." ”

"Come on, we're both almost ninety years old, don't play this kid's stuff with me, what's the situation, let's just say it, I'll listen." Ye Fei said bluntly. (To be continued......)
