With Tony's various operations, the Prinz Eugen displayed on the workbench has changed a lot.

First of all, the above and underwater parts of the hull have been fine-tuned with some fine-tuning and have become more modern. This tweak alone makes the ship a little different from the original Prinz Eugen.

Even without considering the factors of black technology, Prince Eugen's World War II design scheme has many outdated places, and the superstructure has almost been adjusted and optimized by Tony.

Miraculously, Tony retains the original characteristics of Prince Eugen, and at a glance it is still Prince Eugen and not another ship.

"See how it is now?"

Ethan had been watching from the sidelines, and he didn't have any problem with Tony's adjustments, at least in his opinion, they were all good.

"There won't be any changes on the outside, so we're going to think about the specifics...... The power of this ship are you going to use the Ark reactor?"

At first, Ethan wanted to use the strange magic stone he found that almost never decayed as an energy source, but at that time, he was not thinking about directly building such a large steel battleship, and he was very skeptical that the magic stone had such a strong output power.

After telling Tony about the magic stone he found, Tony temporarily set the Ark reactor as the main energy source for the battleship after asking him to study it for a while.

The Ark reactor is actually a cold nuclear fusion reactor, in the world where Ethan once lived, cold nuclear fusion was only a technology that existed in theory or even fantasy, and many scientists believed that cold nuclear fusion was a technology that could not really appear.

However, in the Marvel world, this technology has been successfully researched, manufactured and developed by Stark and his sons, and it is already a very mature technology, whether it is output power, stability and service life, there is no problem as the power core of a warship.

"A cruiser that looks like a World War II era on the outside, turns out to be nuclear-powered on the inside. ”

Tony suddenly felt that things weren't as boring as he thought, especially since Ethan was still going to install all kinds of magic equipment on the ship, as well as the kind of magic stone equipment that he hadn't studied in detail.

"Energy barrier?"

Ethan chose the naval cannon as the main weapon design because the new ship will use energy weapons as the main means of attack, although Tony has decided to make magic changes on it, but he really didn't expect Ethan to install an energy shield on this ship.

"And it's multiple defenses. ”

He doesn't just design an energy barrier, he also uses magic to create a magic shield, and he also studies how to transplant the protective energy on the armor to the battleship.

With so many layers of defense, he believed that the defense of his battleship was absolutely strong enough to collapse the enemy, and ordinary attacks might not even be able to break the outermost shield.

Coupled with Tony's modification of several anti-aircraft gun emplacements into phalanxes and missile launch boxes, the defense of this Prince Eugen has reached the limit that the two of them can think of at the moment.

The two men continued to discuss, and as Tony learned more about Ethan's requirements, he made more adjustments to the ship.

It's nothing just to make some optimizations to the hull, and then it's really a major operation.

Although the superstructure looks similar to the original Prince Eugen on the outside, the interior and many details have changed dramatically.

In addition to the installation of the phalanx and the missile launch box, the chimney that occupies a huge space has been transformed into a vertical launch system by Tony on the premise of retaining the original appearance, and Ethan can only look at Tony with a smug face when he learns this.

"I'm going to build a World War II ship, just because energy weapons don't need to worry about logistics, where can I replenish them if you run out of so many missiles?"

"I'll talk about it when you're done. ”

Tony didn't care about that, he was finally having some fun now, and of course he had to satisfy himself first.

"Considering that you have a small crew on board and a huge amount of space inside the hull, the part that originally carried the seaplane can be transformed into a lifting platform, and the plane can usually be parked in the ship's warehouse, and if necessary, the platform can be used to lift to the outside of the ship, or you can open the platform skylight and take off in the ship. ”

The aircraft on this ship is certainly capable of vertical take-off and landing, and it makes sense to have several different aircraft types to suit different needs, given the variety of situations.

"Do you have any requirements for the plane?"

"I'd love to get a couple of VFs, but I can't. ”

"VF? what is that? some kind of high-tech flying machine?" Tony would always be interested in something Ethan occasionally mentioned, as it was probably a product of another world, and the name sounded like a code name for some kind of technological artifact, probably from some world with a higher technological civilization.

"A variable dual-purpose fighter with space and atmosphere, which can break through the atmosphere in a single aircraft. ”

Tony's eyes lit up, as if he wanted to ask for more details, but Ethan quickly turned the subject back to the Prince Eugen in front of him.

"Speaking of which, it suddenly occurred to me that the boom couldn't be removed. ”

"Why?"

Battleships in World War II had a boom, and an important role was to recover the reconnaissance aircraft that landed on the surface of the water and 'catch' it back on the ship.

"Because the boom is needed to load supplies. ”

Ethan also just thought that if he changed the ship, even if it was just to replenish food, then it would be a very huge workload to fill the warehouse, and it was obviously unrealistic to rely on manpower to carry it back and forth.

If there is a boom, the supplies can be lifted up to the ship in one go, and then placed directly into the ship's warehouse if possible.

In the days of sail warships, there was this idea, using tools such as turntables and gears to lift the materials piled up on the dock above the deck, and at the same time, there was a 'skylight' on the deck that could be opened, so that the supplies could be 'placed' directly into the warehouse.

Ethan also suddenly remembered this, Tony didn't expect it, because modern docks have all kinds of equipment, a lot of machinery for loading and unloading, and there is no need to install similar things on the ship to occupy space.

Although it is not clear what the situation of Ethan's world is, Ethan's special mention proves that there is a need, and Tony has to 'install' the crane arm that has been removed.

By this time, the framework of the ship had been roughly set, and the remaining details would have to be discussed slowly for the time being, as Tony still had to figure out what was going on with the magic stone technology that Ethan had given.

Basically, everything that can be determined is now decided, and it will take time for Tony to study the things Ethan has come up with in the same way, and see how these things should be perfectly transplanted or modified and installed on this battleship, which will take some time.

Tony was a research maniac, but he knew how to relax, and after archiving the rough design, he took Ethan, Diana, Logan, and Laura to a big meal.

Diana bought a lot of clothes and shoes in the company of Pepper Pepper, and gave a very detailed science and teaching to this demigod who was not very adapted to modern urban society.

Of course, Logan did not miss this opportunity to throw money around, he unceremoniously bought a lot of cigars, and Ethan was sure that for a long time to come, even if Logan had a cigar in his mouth all day, he would not have to worry about running out of cigars in a short period of time.

After playing for most of the day, Tony, who returned to Stark Building, immediately grabbed Ethan and entered his laboratory.

His Stark Mansion has a variety of laboratories with a variety of equipment, as well as a large storage of materials that allow him to conduct research on the go—and to upgrade and craft new steel armors whenever he wants.

After he had enough of eating, drinking, and having fun, he grabbed Ethan directly to the laboratory, because he was curious about the magic stone technology that Ethan had mentioned more than once, and he was very eager to understand what this technology was all about, even if he didn't have Prince Eugen's design work, he was very eager to learn about this technology from another world.

"That's it?"

"This is it. ”

What Ethan had brought out was the armor he had taken from the Assassin. The most technical magic stone equipment in his hand is this armor, which is much more technical than those thrusters or something.

"What are these things capable of?"

Ethan recalls it for a moment, then describes the full capabilities of this armor in the simplest terms: "Optical Stealth, Silence, Energy Defense, Strength, and Speed Enhancement." ”

"Oh?"

Tony didn't care much about this set of equipment, but he became interested when he heard Ethan's description, and asked Jarvis to do a detailed scan of this set of equipment while asking Ethan about various details about this set of armor.

As Tony's understanding of this suit deepened, so did his knowledge of the magic stone technique.

"To put it simply, this so-called magic stone technology is to rely on a specific prop to bring out the special role of a certain energy, this technology is too limited, if you want to use this technology on your own ship, you will be subject to a lot of restrictions. ”

For a simple example, if Ethan uses the magic stone propulsion device on his new ship, then after the thruster loses energy or is damaged, he must find a magic stone with the right properties to replenish energy or repair it, which will cause huge problems for logistics and maintenance.

"So, it's best for your new ship to have the Ark reactor as its main power source. ”
