At the same time as these two actions led by Fang Yan were launched, a worldwide influential naval disarmament conference also kicked off in London, England, in the spring of 1930.

For the host country, Britain, the convening of this meeting is undoubtedly full of bitterness and bitterness. Because just three years ago at the Geneva Conference, they vowed to build 70 cruisers to secure the lines of communication no matter what; Over the next two years, however, a heavy blow followed. In 1928, the United States announced that it would build 15 10,000-ton cruisers in the next three years, which was clearly a countermeasure to Britain's ambition to regain its position as the single strongest navy through the massive construction of auxiliary ships. A year later, the economic crisis triggered by the collapse of Wall Street stocks swept through the United Kingdom like a hurricane; Britain's financial foundation, which was originally the foundation of the sunset, shrank sharply as if the ball had been punctured, and even if the naval arms race of the cruiser class was launched again, the British government would not be able to support it!

The only consolation to the gentlemen of London was that all the major powers, including the United States and Japan, had been hit by the Great Depression, and the cruiser race that had been in full swing in the second half of the twenties had finally died down under this cold snap. In order to maintain its current naval position at minimal cost, Britain, shortly after the Great Depression spread, proposed that the signatories of the Washington Treaty "meet" again to close the loophole that had not previously limited the number of cruisers. In fact, as early as two years ago, Britain had already had the idea of compromise after the United States began to exert its strength, and now it has undoubtedly given them an ideal excuse and opportunity.

On April 22, the London Naval Treaty, which was intended to supplement the Washington Naval Treaty, was officially promulgated by the United States, Britain, and Japan. Its main contents include the reclassification of cruisers: those equipped with guns of more than 155 mm caliber are defined as heavy cruisers, and those with main guns smaller than this caliber are light cruisers, and the shares of the United States, Britain and Japan in these two types of ships are 180,000 tons, 146,000 tons, 108,000 tons, and 143,000 tons, 192,000 tons, and 100,000 tons, respectively. The standard displacement of destroyers must not exceed 1,850 tons, the caliber of artillery must not exceed 130 mm, and the total holdings of the United States, Britain and Japan are 150,000 tons, 150,000 tons, and 105,000 tons, respectively.

Due to the large differences between various parties, France and Italy who participated in the meeting did not sign the treaty in the end. However, Britain is obviously not willing to accept that the arms limitation treaty, which it has worked so hard to build, will be disrupted by the competition between these two countries in the Mediterranean; Under the combination of hard and soft, an unwritten agreement was finally concluded with these two countries. France and Italy stopped the competition for the construction of heavy cruisers, and in the future, only light cruisers with weak combat effectiveness were developed in the field of cruisers.

For Fang Yan, the conclusion of the London Naval Treaty was undoubtedly a matter of celebration. Because in order to ensure that there were a sufficient number of cruisers to maintain its long sea lines of communication, Britain was forced to abandon the share of heavy cruisers with higher combat effectiveness of a single ship, and instead increased the total tonnage of weak chicken light cruisers, and its effectiveness was undoubtedly far behind that of heavy cruisers. And because Britain has already completed the 146,000-ton heavy patrol quota, it can only build light patrols in the future, which reduces a great obstacle for the German Navy in future operations.

In addition, according to the notes to the treaty, 4 Iron Duke-class battleships of the British Navy and the battlecruiser HMS Tiger were to be decommissioned within the next two years. Although these capital ships equipped with 343 mm guns are outdated, if they are retained and rebuilt on a large scale, they will also be able to rejuvenate themselves in future naval battles. Just imagine, even the Italian Navy's Cavour-class old dreadnoughts can become a 27-knot quasi-high-speed battleship after refitting, and the usability is greatly improved; So what reason does the Iron Duke, whose foundation is two or three grades better, not be reborn? Not to mention the Tiger Patrol that was born with a high speed of 28 knots!

Whether it was the Washington Naval Treaty signed in 1922 or the London Naval Treaty currently being concluded, Britain, which was in the waning days, had to rely on cutting itself down first to show its sincerity to peaceful disarmament to other countries.

Fang Yan would not pity the fate of this old bandit who had vainly tried to dominate the sea power in the past. On the contrary, he will do his best to keep nailing screws around this enemy who has been lying in the coffin, in order to bury him completely in the loess and remove this cancer of hatred and war from the world. One of the nails that Fang Yan wants to nail at present is to sell the aircraft carrier design he has completed to the navy that has already done so.

The Navy Headquarters directly under the Berlin government was responsible for formulating the development plan of the fleet, and although Fang Yan was already famous at this moment, it was still impossible for him to directly participate in the decision-making of the top level as a lieutenant. However, Fang Yan had already had a significant influence on the will of the Navy's top brass by writing papers and communicating privately with Supreme Commander Raeder. Shortly after the conclusion of the London Naval Treaty, Fang Yan learned from his family's channels about the latest actions of the naval headquarters: the latter had decided to purchase two aircraft carriers this year, and the standard displacement of the shipyard's plan needed to be controlled within 13,000 tons.

"Yay!" Fang Yan's eyes lit up when he put down the letter, and his hands couldn't help but clench into fists. Although there is still a certain gap between this and his ideal plan, the German Navy dared to take this step, which in itself was a revolutionary breakthrough that broke the mold of history. With these two small aircraft carriers as the precursors of experimentation, the German Navy's air-sea path could flourish through continuous training and precipitation, and 10 years later it would shine again against the British.

Only two days later, Fang Yan completed the revision of the plan. He immediately contacted Rudolph, the cheap daddy, and said that he had come up with an ideal plan, hoping to represent the shipyard to the naval headquarters in Berlin for technical exchanges. Rudolph had long known about his young son's attributes, and he was very relieved to hand over all the technical matters to Fang Yan to deal with, and only waited for the good news from the other party at home.

The headquarters of the German Navy is a four-story Romanesque building on Berlin's Kaiserstrasse, with gray and yellow walls and blue square windows. Although Fang Yan has been in this group for nearly 6 years, and has directly influenced the construction of two-level warships before, it is still the first time that he has come to the center of naval power. The guards in front of the building saw Fang Yan in the uniform of a lieutenant and several engineers in suits and leather shoes coming with the team, and thought that Fang Yan was their own liaison who went to receive these people; However, when he carefully checked Fang Yan's pass, his eyes showed a look of disbelief in shock.

"Honorable lieutenant, you turned out to be the technical representative of the Brom-Fox shipyard?" The soldier seemed to have discovered something most incredible, and spoke a little sluggishly. Fang Yan was a little unnatural by the soldier's eyes, he turned to the door and coughed, signaling that the other party should be able to allow him to enter. In fact, Fang Yan didn't want to be so high-profile in his heart, he had retreated into the background in the two technical exchanges held at the Navy Headquarters before, but this time, what he wanted to sell was an aircraft carrier that would be the main force in the future, which made him have to show his thinking and concepts to the military top brass completely, and do his best to win their approval.

The Germans have an unusually strong sense of punctuality, and not long after Fang Yan and the others sat down in the venue, several other men in neat dresses also walked in. A middle-aged man with gray temples was faintly headed, his eyes flashing in all directions. Based on the previous homework, Fang Yan understood that they were from William Shipyard, and the middle-aged man was Berner, the chief naval engineer of the factory, and this time he was competing with him as a competitor.

Today, Brom-Foss is in charge of most of the German shipbuilding industry, and even the Germania shipyard owned by Krupp in the past is controlled by Rudolfin; The only one who still insists is William Shipyard, the former industry leader. Obviously, this is the result of the German Navy's deliberate maintenance of the latter: after all, if the entire domestic shipbuilding industry is controlled by Brom-Forss, then the Navy will fall into a complete passivity when ordering warships, and then the price of the contract will not only be determined by Rudolph?

In order to keep the next Tinder enterprise that could make Brom-Foss lower the price, the German navy top brass even raised the national righteousness, which was worthless to the capitalists of this era, and persuaded Rudolf to transfer the unconventional design methods proposed by Fang Yan with open hanging effect to Wilhelm Shipyard. Seeing that the navy was determined not to allow himself to form a complete monopoly and did not want to tear his face with the navy, Rudolph could only reluctantly transfer the design means last year. Although William Shipyard, like Ansaldo in Italy, had to pay royalties for this, it undoubtedly broke Brom-Foss's unrivalled position in the field of warships. This aircraft carrier order is their first appearance after integrating these techniques.

A few minutes later, more than a dozen naval officers led by Raeder also entered, none of them were as young as Fang Yan, and the last epaulettes were the lieutenant colonel with silver braids and gold stars. Seeing that Fang Yan, a lieutenant in military uniform, was actually sitting in the chief representative seat of the Brom-Forss shipyard, almost all the senior officers had their pupils narrowed; However, Raeder seemed to have expected it, he glanced at the audience, and said bluntly: "Since everyone has arrived, let's enter the part of the plan presentation." ”
