Chinese warships, destroyers, and submarines, which are popular types of ships in today's world, are all innovations of the warship design bureau or Fang Xiaoyu. Then the biggest innovation of the warship design bureau is still the amphibious hull, which includes flat-bottomed landing craft and combat vehicle landing ships. The emergence of comprehensive supply ships has unified a series of supply ships such as coal and water ships, material supply ships, and ammunition supply ships into one ship, which has greatly accelerated the supply speed of warships and made the fleet's voyage much easier.

This time, the warship design bureau stepped in again and designed several new warships for the Imperial Chinese Navy to evade the restrictions of the Rome Convention, the first of which was the Yushan-class dock landing ship with a wide deck at the back.

A dock landing ship is a warship that can carry amphibious landing ships, amphibious combat vehicles, and hovercraft. Its cabins are semi-draft to facilitate access to amphibious landing vessels, amphibious combat vehicles, and hovercraft, like a shipyard, while its aft deck can accommodate a large number of helicopters, which were unique to the Chinese Empire and had a wider range of uses.

There are two kinds of helicopters carried by dock landing ships, the first is the Meishan-class cruiser that has begun to be equipped, the 22-meter-long Wasp-type medium-sized anti-submarine multi-purpose helicopter, the maximum level flight speed of this helicopter can reach 267 kilometers per hour, the maximum range is 300 kilometers, equipped with anti-submarine radar, sonar buoys and depth charges, its detection distance to the submarine is several times larger than that of a simple destroyer anti-submarine, and because there is no destroyer's propeller noise interference, its anti-submarine efficiency is higher, and it is an absolute anti-submarine weapon.

The Wasp-type medium-sized anti-submarine multi-purpose helicopter is specially equipped for the anti-submarine of the fleet, and it is not at all the regular equipment of the dock landing ship, and the role of the twin Wasp transport helicopters carried on the landing ship is obvious.

Equipped with two pairs of tandem counter-rotating three-blade rotors, the twin wasp transport helicopter is specially designed for transporting troops, this kind of helicopter similar to a large bus, the internal payload can reach 6,512 kilograms, the maximum level flight speed is 280 kilometers per hour, it can transport 35 fully armed soldiers at a time, and transfer artillery and other large equipment under the plane, and is the absolute main equipment for transporting troops in the air assault force.

The carrying of such transport helicopters allows the dock landing ship to achieve vertical landing capabilities, which can completely ignore the terrain and land on any coastline. Originally, only 17 percent of the world's landing craft and hovercraft could be landed, but now with the vertical landing method, 80 percent of the coastline that can be landed has become 80 percent, and this will greatly enhance the suddenness of the navy's amphibious landing.

It's just a pity that the Yushan-class dock landing ships are mainly used for the landing of surface ships, and the helicopter hangar is not large. In addition, only the rear half of the hull is a flat deck, so the Yushan-class dock landing ship with a displacement of only 18,500 tons can only allow three helicopters to take off and land at the same time, and the hangar can only park a maximum of four double Wasp helicopters, plus two Wasp anti-submarine helicopters, and its landing capacity is limited.

Originally, according to the idea of the warship design bureau, the imperial navy should also build a 30,000-ton amphibious assault ship. This kind of amphibious assault ship is a type of ship specially used for helicopter vertical landing, and he has transformed the warship more thoroughly, not only has a large hangar, but also has a straight through deck, both the take-off and landing efficiency and the carrying capacity are greatly increased compared with the Yushan-class dock landing ship.

It is a pity that the aircraft carrier stipulated in the Rome Convention is too similar to the amphibious assault ship, and if this type of ship is built, it is easy to cause misunderstanding and cause unnecessary international disputes, so Fang Ruijun temporarily stopped the construction plan of this kind of warship and waited until the right time in the future.

Congress had little to say about the construction of these new warships, so a new round of naval expansion bills was quickly passed. A large number of warships outside the treaty restrictions were built, including 25 Yushan-class dock landing ships and 50 Pinghu-class comprehensive supply ships with a displacement of 35,000 tons.

In terms of the Air Force, Fang Ruijun secretly ordered various aircraft factories to start mass-producing Golden Eagle 4 jet fighters and Kunpeng 3 jet bombers. These two types of aircraft are currently being built for stockpile, not to equip the troops, so that they can be quickly reequipped in case of an emergency, and the Wehrmacht Air Force has also begun to train in batches in inland areas, where the Guards Air Force will teach them the various techniques of flying jets, lest no one will fly the aircraft when it is time to change their equipment.

The same is true for the army, although in order to avoid irritating other countries, the army does not reequip, but a number of high-tech equipment such as the new Grizzly 3 combat vehicle and the Storm Bear 2 series self-propelled artillery have also begun to be stockpiled to expand the national strategic arsenal.

Fang Ruijun has aggressively expanded his armaments to prepare for a possible war after the economic crisis, and the reason why he dared to predict the outbreak of the economic crisis when the financial crisis began to stabilize was because he still had a trump card in his hand, and this trump card was also the reason why he was so sure that the economic crisis would come after the financial markets of various countries stopped one after another.

At this time, all countries closed their foreign exchange markets, and currency exchange could not continue, so the Chinese dollar, which had been maintained on the gold standard, became the new international currency and was used as the only designated currency for foreign exchange settlement. But governments did not expect that a complete halt in the financial market would not stop Fang Ruijun's economic attack, because the Chinese Empire has always had a rather powerful weapon, that is, grain.

As early as the era of the Chinese leader, Fang Xiaoyu relied on a food crisis that affected the world and earned a lot of money and interests, which also directly provided a large amount of money for the Chinese leader, and accelerated the pace of the rise of the Chinese leader for several years, but since then, the Chinese empire rarely uses grain to attack enemy countries, but has been selling grain to the whole world at a parity price, which has made the major powers that have always been industry-centered relax their vigilance against this.

Countries have relaxed their vigilance against agriculture after increasing their support for their own agriculture, but the Chinese Empire has not let up, and they have been attacking the grain markets of various countries with their agricultural products. Due to the low cost, high yield, good quality, and abundant supply of grain in the Chinese Empire, the agriculture of all countries suffered a considerable blow, and it was only because all countries subsidized the state treasury that the agricultural output value and cultivated area did not shrink seriously.

Governments of various countries are also aware of this situation, they can rely on government funds, increase investment to support their own agriculture, but that will occupy a large amount of government finance, compared to the support of industry such a policy is really not cost-effective, plus the Chinese Empire has been supplying food at a low price, the governments of the government after carrying out part of the strategic grain reserves, relaxed their vigilance, for their own agriculture is only a little support.

By 919, the population of the countries of the world had exceeded 3 billion, and the grain production of all countries except NATO, although declining slowly, was less than 70% of what it had been 20 years ago. It was in this context that during the summer harvest season in June 919, the Chinese Empire suddenly announced an increase in the price at which grain was sold.

Just when countries were trying to adjust their economies and stabilize prices, Fang Ruijun began to make trouble. Under the pretext of reducing grain production, Fang Ruijun raised the price of major grains tenfold in one go, and at the same time he also said that in order to stabilize the development of the country's economy, the Chinese Empire restricted grain exports and began to impose 60% restrictive export tariffs, while tariffs were abolished on grain imports.

NATO has always been the breadbasket of the world, and the grain they produce every year has a share of more than ninety percent in the world. Since the last food shortage, countries have established grain reserve mechanisms, but with the advent of the World War, and the Chinese Empire, which has been selling grain at a fair price for many years, governments have gradually relaxed their vigilance.

Grain reserves were originally relatively capital-intensive, and in a period of rapid economic development, the behavior of occupying funds in grain reserves was naturally gradually reduced, so when the Chinese Empire began to restrict grain exports, governments of various countries suddenly found that their strategic grain reserves could not support it for too long.

The prices of various countries are already very high, although the financial markets of various countries have been stopped, but the harm of the bubble economy has long been on the verge of breaking out, and Fang Ruijun's use of the food problem to suppress countries at this time has undoubtedly become the last straw that crushes the camel.

The shutdown of the financial markets, the inflation that the state could not stop, and the sudden rise in food prices drove up the overall prices, and the prices that had just begun to ease because of the country's economic austerity policy rushed up again, and the financial austerity policies that had begun in various countries became their lifeline.

Prices began to rise uncontrollably, while people's purchasing power was greatly reduced, which directly led to the emergence of another economic crisis. The sharp decline in the domestic economy frightened the Boston government, and the Boston think tank immediately proposed to pass on the economic crisis through Boyuan's status as the currency of the world world, so the money printing machine of the Boston empire rumbled again, printing money with all its might, but unfortunately they did not expect that the world world currency can certainly tie the world world economy to their chariot, and they are also easily sent to hell by the world world economy.

While the Boston Empire was printing money frantically and passing on economic losses to the Allied countries, the Yaman Empire and several other major Allied countries had no choice but to announce higher tariffs and rely on increased exploitation of the colonies to tide over the crisis. With regard to the colonial exploitation policies of the major Central Powers, the few countries that had lost their colonies were in bad luck.
