The banquet was a success, at least that's what Zheng Jiangming thought.

In fact, it was not until the end of the banquet that Bai Zhizhan learned from Zheng Jiangming. The Empire sent several air force generals over to discuss cooperation with the Empire. To put it simply, it is to exchange what the empire is interested in for equipment and materials that the empire urgently needs.

Of course, this includes radio-controlled bombs.

The empire used it in exchange for warships.

In fact, this is also a previously agreed cooperation project.

According to Zheng Jiangming, in the name of compensation, the empire handed over two "Xuhai" class ships to the Navy, and provided supporting ammunition, such as 400 mm armor-piercing shells, before the mid-term overhaul.

For the same reason, the standard ammunition of the Manman Navy is different from that of the Imperial Navy, and there is no way to use it universally, and there is no need to build a special production line.

In addition, the Empire helped the Empire to build two fast battleships developed from the "Asahimi" class through technical assistance.

The main thing is to replace it with the 380 mm naval guns of the Yama Navy.

Two "Asahimi" class ships will also be replaced with naval guns of the Empire during the mid-term overhaul.

It's just that the so-called assistance is actually to provide "Xuhai"-level design drawings. The so-called transformation is nothing more than an adjustment made in order to adopt the standard equipment of the Manman Navy.

As for whether the shipyards of the Empire can build such warships, it has nothing to do with the Empire.

Fast battleships are not the point, though.

After two years of negotiations, the two sides finally reached an agreement on a cooperation project involving aircraft carriers, or the Imperial Navy made concessions.

The Empire will provide the design drawings of the "Imperial Capital" class to the Empire, and arrange engineers to modify the design according to the needs of the Empire.

To put it simply, it is based on the "Imperial Capital" class to build a fleet aircraft carrier tailored for the Manman Navy.

If anything, the main thing is to enhance the seaworthiness of the aircraft carrier in view of the bad weather in the North Sea and the North Sunset Ocean, and appropriately reduce other performance, such as the number of carrier-based aircraft.

In addition, the size of the flight deck and hangar, such as the height of the hangar, needs to be adjusted according to the carrier-based aircraft of the Navy.

Other weapons, such as anti-aircraft guns, were also to be used as the main equipment of the Navy.

To put it bluntly, only the hull of the "Imperial Capital" class is used, and almost all the others have to be replaced.

In order to obtain aircraft carriers, the Riman Empire also smashed its old capital.

The first is to provide the Empire with the design drawings of the latest submarines, and to help the Empire's shipyards master the construction of new submarines.

Secondly, radio remote control technology was provided, as well as a batch of remotely controlled bombs for testing.

The key is the submarine, especially the new battery, and the new power system.

This includes closed-cycle engines.

If anything, this is also the main purpose of Dunz's visit to the banquet, to ensure that the Imperial Navy can be interested in the new submarines of the Manman Navy, and is willing to exchange the advanced technology of building fleet aircraft carriers for the advanced technology of submarines, so as to ensure the smooth implementation of its aircraft carrier program.

Interestingly, on the issue of treating aircraft carriers, Dunz has always been opposed.

The reason is also very simple, the Riman Empire does not have the capital to develop a fleet at all, and it is impossible to compete with the powerful Liang Xia Navy in the open ocean.

In addition, during the Great War, it was enough to have the Liangxia Navy.

Fundamentally, it is still national strength.

An aircraft carrier is nothing more than a kind of warship, and in order to give full play to the combat effectiveness of an aircraft carrier, it needs supporting combat aircraft and escort warships.

Getting this whole set down is not as simple as building an aircraft carrier.

In the Imperial Navy, for example, in an aircraft carrier battle group consisting of 1 fleet carrier, 1 fast battleship or large cruiser, 2 heavy cruisers and 2 to 4 light cruisers, and 4 to 6 large destroyers, fleet aircraft carriers account for only 20% of the cost. If you count nearly 100 carrier-based aircraft, as well as auxiliary ships such as fleet oil tankers, the proportion of fleet aircraft carriers is even lower.

Obviously, there is not enough national strength to raise an aircraft carrier at all!

It is precisely for this reason that the High Giant Kingdom and the Daiman Kingdom have listened to the advice of the Imperial Navy and purchased several light aircraft carriers from the Empire in the form of financial assistance. That is, it was used by the Imperial Navy in a major war, and after the end of the war, it was handed over to the navy of the contributing country.

Although the Empire is much stronger, it is not so easy to form several aircraft carrier battle groups.

Of course, there is also the post-war international situation.

In fact, this is also the main reason why the Liang Xia Empire has been reluctant to help the Yuman Empire build aircraft carriers.

In Zheng Jiangming's words, after finally defeating the Western powers and becoming the hegemon of the global ocean, is it possible to support a new opponent?

Unfortunately, this matter is not negotiable at all.

In the end, the Imperial authorities had to make concessions and exchange the fleet carriers for the new submarines.

Of course, the most important thing is that the Imperial Navy now has large aircraft carriers, and there are plans to build supercarriers.

It is only a matter of time before the fleet aircraft carriers take a back seat or even be eliminated.

Compared with the Rimman Navy, there is indeed a big gap between the Empire's submarines, and obtaining relevant technology from the Empire is one of the most ideal choices.

In addition to technology, the two sides also need to exchange materials with each other.

Of course, it was mainly the Liangxia Empire that provided aid to the Riman Empire.

This includes a lot of special goods that the Empire couldn't get hold of, but were in great need, such as quinine from the tropics.

Although long before the outbreak of the Great War, the Manman Empire followed the example of the Liangxia Empire and hoarded a lot of drugs such as quinine for the treatment of tropical diseases through civilian procurement channels for fighting in the tropics, the consumption of the war far exceeded the pre-war predictions.

Fortunately, the Empire had swept through the southeastern part of the vast continent and taken control of the quinine region.

However, the most important material is actually oil.

In this regard, it is not the turn of the military to call the shots.

In Zheng Jiangming's words, when the empire decided to send troops to Posha Bay, it was negotiating and consulting with the Empire of Horman, the Kingdom of Raleigh and the Republic of There.

This is also the number one contradiction within the Entente.

Although according to the agreement, Posha Bay will be returned to the Republic of There, but the agreement also stipulates that the Liangxia Empire will unconditionally obtain the right to exploit the Posha Bay oil field.

In other words, the Liangxia Empire distributed the oil produced.

According to the distribution plan originally proposed by the imperial authorities, only about 35% of the production capacity was provided to the allies after meeting their own needs.

Obviously, this is not enough.

The demand from the Palman Empire accounted for 30% of the total oil production capacity of Posha Bay, and the Raleigh Kingdom also had a lot of demand, as well as the Republic of There, as well as small countries such as the Daiman Kingdom.

After arduous negotiations, there was finally an outcome acceptable to all.

60% for the Empire, 25% for the Empire, 6% each for the Raleigh Kingdom and the Republic of There, and the other 3% for other allies.

Crucially, the Empire unconditionally shared coal catalysis technology to alleviate the problem of tight oil supply.

In addition, the agreement will be automatically nullified after the capture of the caves.

Most importantly, the Empire promised to retake the Romanian oil fields within a year, after which it would reduce the scale of its oil imports from Posha Bay.

Of course, these are high-level things.
