Considering this factor, Fang Yan obviously needs to reserve an 11-inch main gun for the new 10,000-ton ship. In fact, the resulting European naval race, in addition to freeing Germany from the shackles of the Treaty of Versailles, allowed Italy, its future ally, to develop its naval power in the process. The latter will obviously play a great role in the future war against Britain. As for the French navy, which has also expanded its strength in the arms race, it is not at all a matter of concern, as long as Germany can defeat it on land, as it has done in the historical plane, then the French fleet can only disarm and lock itself in the harbor!

In terms of secondary firepower, Fang Yan also had to make corresponding modifications. Historically, the eight 150 mm secondary guns equipped with Germany could not be used against the air, and the redundancy left for the installation of small-caliber anti-aircraft guns in the future was also very limited, which undoubtedly made it lack the ability to protect itself in future naval and air battles. In view of this, Fang Yan prepared to equip it with a 128 mm secondary gun, and at the same time left corresponding space for the future installation of anti-aircraft guns. As for the rationale for choosing a smaller caliber secondary gun, Fang Yan also has a perfect explanation: the 283 mm main gun is enough to effectively deal with enemy cruisers, and the 128 mm secondary gun, which has a faster rate of fire, can ensure a strong countermeasure against the current increasingly large destroyers.

In terms of power, Fang Yan gave up the historical version of the diesel engine and still chose the traditional steam power system. At present, its own shipyard has completely integrated Italian technology and embarked on a new path, whether it is in terms of volume, weight, output strength, or reliability, it is much higher than the large diesel engine that has just been developed. Even in terms of fuel consumption, steam power can be compensated for by cruising turbines, narrowing the gap between it and diesel engines to a completely acceptable level. In addition, high-speed warships can also accompany aircraft carriers in future operations, which is not possible with slow diesel-powered warships.

As for the armor, Fang Yan still aimed to defend against the 203-mm guns of the treaty cruisers, laying protection comparable to that of the Type 1926 cruisers. Although this design is obviously suspected of attacking and defending weakly, due to the special background of the current "Washington Treaty" signed by the major powers, it is impossible to build cruisers equipped with larger caliber guns, so Fang Yan's definition of attack and defense is completely timely and correct.

After determining the details of the new 10,000-ton capital ship, Fang Yan immediately informed Lane of these requirements, and asked the other party to make a design plan based on this information. He was now serving as a senior officer on the battleship Silesia, and was unable to spare time for the laborious design of the ship. In addition, Fang Yan also wanted to see how these old-fashioned and rigid engineers in history could reach under their own changes. After all, it is impossible for him to devote his main energy to this purely technical field in the future, and there are undoubtedly more important obstacles to overcome on the road to changing the fortunes of the German nation.

Facts have proved that Fang Yan still underestimated the designers of his own shipyard. Since piercing the layer of conceptual window paper, the technical team led by Ryan has shown a high degree of professionalism: they have not only implemented Fang Yan's concept, but also handled many technical details more precisely than Fang Yan. In less than a week, a preliminary case was sketched out on the drawings. It was armed with two quadruple 283 mm L45 guns, six twin 128 mm L45 secondary guns, and a small number of anti-aircraft guns. If needed in the future, the ship can also be equipped with a total of 40 40 mm and 18 20 mm small-caliber anti-aircraft guns.

In addition, 6 large heavy oil boilers and 2 gear reduction steam turbines provide a stable output of 80,000 horsepower for the ship; Even with a full load displacement of 16,100 tons, it can still reach a speed of 30 knots. Due to the role of the cruising turbine, the ship is designed to carry 2,800 tons of heavy oil, which can provide it with an excellent range of 12,000 nautical miles at a cruising speed of 15 knots, which can effectively meet the needs of breaking diplomatic relations in the ocean. The 140 mm main armor belt with an inward inclination of 20 degrees, the 60 mm main horizontal deck, the 180 mm turret front and turret armor, and the 100~30 mm gradually thinning TDS defense can achieve immune resistance to 203 mm shells at normal engagement distances. Although the standard displacement of 12,850 tons was required to achieve these performances, which greatly exceeded the 10,000-ton limit allowed by the peace treaty, the ship's 172-meter waterline length was not as long as that of the treaty cruisers of the Great Powers, and it was also very feasible to conceal the tonnage. You must know that the historical Spee also has a standard displacement of 12,473 tons, and this degree of overweight obviously will not cause a violent reaction from the Entente.

"Eight 11-inch guns, that's definitely an amazing firepower that would make all treaty cruisers shudder!" After incinerating the photocopies of the drawings he received, Fang Yan said with undisguised praise. In addition to the number of guns, he instructed Ryan to significantly improve the shells that directly damaged enemy ships: not only did the weight of the shells increase from 302 kg to 400 kg, and the slender hood was added to improve the storage rate, but the ammunition type was changed from armor-piercing to semi-armor-piercing. In this way, the improved new SAP shell can still easily penetrate the light and thin armor of the treaty cruiser, but the charge is doubled compared with the AP shell, and one round can withstand two explosions. Considering the huge caliber advantage it possesses, this type of battleship undoubtedly formed an absolute firepower crushing against treaty-type cruisers!

In terms of performance, the ship already had all the characteristics of a battlecruiser: the firepower of a battleship, the speed of a cruiser, and the armor to withstand the gunfire of a cruiser. If the historical plane Spee is replaced with this type of battleship, then it will have every chance to turn on the Musou mode in the battle of the mouth of the Laputara River, kill all the opponents and fly away. Although this type of ship is not the ideal protagonist in Fang Yan's mind, it will also play a great role in breaking diplomatic relations at sea with its superior performance in future maritime operations.

"Then recommend this plan to Raeder, and strive to let the Navy set a time to start construction as soon as possible." Fang Yan thought in his heart. Although this kind of self-nomination is not in accordance with the normal rules, the current Brom-Forss is fully capable of doing so: not to mention that more than half of the German shipbuilding industry is now owned by Rudolf, and its few design techniques and power technologies alone are absolutely indispensable to the German Navy. Even if it has not been tested by the actual exercises and war games of the General Staff, it is necessary for the Navy to take the plan proposed by the shipyard seriously, not to mention that Fang Yan also has a good relationship with Raeder, the absolute power in the Navy. As for whether the top brass of the Navy will adopt their own ideas as scheduled, Fang Yan has sufficient confidence in his heart; After the keels of a few ships have been laid down in this pocket battle cruiser, his aero-type battleship will also be on the scene.

The summer of 1927 quietly approached, enveloping the whole of Germany in a warm atmosphere. Fang Yan, who spent his 19th birthday under Sylvia's sweet smile, undoubtedly felt the obvious change in his environment. At this time, the whole of Germany was in a boiling atmosphere, like the United States on the other side of the ocean, which was working miracles every day; Even compared to the world's top metropolises such as London, Paris and Milan, Berlin is no slouch for its freedom, modernity, and excitement.

The massive infusion of loans from the United States has restored the country's former vitality. Buildings such as opera houses, sports grounds, luxury swimming pools, and tidy apartments have sprung up in German cities, and industrial giants, including Brom-Foss, who have easily repaid their debts during inflation, have updated their equipment and rationalized their production processes with billions of dollars in foreign debt. The Germanic furnace, which had been dormant, was now bursting into flames again: Germany had grown by more than 22 percent in industrial output for three consecutive years after the Ruhr crisis, and in 1926 it had returned to its peak level of 1913 on the eve of the war. France has undoubtedly been trampled under its feet again, and Britain's total national income is also in sight. The number of seats of far-right parties in parliament is declining with successive elections, which has been matched by the growth of the Social Democrats. Eight years after the end of the war, the Weimar Republic seems to have finally gained a foothold.

Fang Yan's heart was undoubtedly full of joy when he felt this completely different atmosphere of prosperity from four years ago, not only because his family business had gained enough benefits from this prosperity, but also because the German Navy was able to get more funds for building ships from the government with a bulging pocket. Inflation in the past has also allowed the government to clear away the huge debts owed to the population during the war, and now it can inject money into the army without financial hindrance. Although the far-right forces in German society are not as strong as in previous years, the enthusiasm for the sea is stronger than ever. Even moderate Liberals and Social Democrats admired the ideas of Otake's book and believed in the righteousness and necessity of developing their own navy. So far, the German Reichstag has approved the construction of 6 new cruisers, half more than the 4 in the historical plane; And on the 10,000-ton capital ship, Fang Yan also has every reason to look forward to the future budget situation.

As Fang Yan expected, the pocket battle patrol design he gave to Raeder soon became the focus of attention of the Navy's top brass. Despite the technical difficulties associated with the quadruple turret, the huge advantages of the case itself over the treaty cruisers already aroused the interest of the top of the Navy, headed by Cenkel. What makes them even more pleased is that the technical indicators of the case are in surprising agreement with the results of their own multi-party exercises and demonstrations, which is completely an ideal plan tailored for them!
