The resumption of production by the Jiangnan Manufacturing Bureau is also one of the important conditions for the East China Government to use Shanghai as a forward port base to meet the British and French Expeditionary Forces, because only when the Shanghai area has the basic maintenance capability of warships can it be qualified to be the forward port base of the East China Government to meet the British and French Expeditionary Forces. Otherwise, even a complete overhaul of the warship would have to tow the ship back to Qingdao, and such a forward port base would be meaningless.

The landing in Japan and the evacuation of Java were carried out at the same time, so the navy's fleet would also be divided into two groups and act separately.

In fact, the Javanese evacuation operation also has the goal of leading to a decisive battle for the British Far East Fleet, so the warships assigned are also relatively strong, and five battleships will be dispatched, including the latest Gan Jiang and Mo Xie, and three Weiyang, Boyang, and Feiyang.

The British Far East Fleet has a total of 8 battleships, including 6 old man class and 2 centurion class, but the centurion class belongs to the 2nd class battleship, and the combat effectiveness is not strong, and the old man star is a simplified and improved version of the majesty class, although it maintains the armament of the majesty class, but weakens the armor, but only increases the endurance.

Although the British Empire's navy has a tradition of fighting when encountering the enemy, if the enemy's strength is too strong, it is not necessary to fight, and it will not be easy to fight, so the People's Army only dispatched 5 battleships, which is to make the British Far East Fleet think that it has the strength to fight, and take the initiative to fight. The KPA Navy could take advantage of this opportunity to inflict heavy damage on the British Far East Fleet, and also to weaken part of the force before the expeditionary force arrived.

In addition to battleships, the Javanese evacuation fleet also dispatched two armored cruisers, the Jinan and Tianjin, two large protective cruisers Qingzhou and Yizhou, the 1st and 4th cruiser detachments, the 1st and 3rd destroyer detachments, and 16 transport and replenishment ships.

The flagship is the Yueyang ship in the crossing warship, and the commander-in-chief of the claw furrow evacuation operation is Wang Hailong, if it engages the British Far East Fleet, the Yueyang ship does not participate in the war, but provides firing unit guidance for the warships participating in the war. This is mainly because the strength of the fleet is sufficient, there is no need to cross warships to participate in the battle, and it is also for the navy to accumulate combat experience.

Comparatively speaking, the fleet that landed in Japan to fight was much weaker, mainly the two battleships Yuanyang and Yuyang, and the four Zhenyuan-class ironclad ships. Bi Jing's strength is now very weak, there is not a single battleship, and the main force is only two armored cruisers, so the main way to land in Japan is still amphibious landing operations, and naval fleet operations will basically not take place, and the role of warships is mainly to provide escort and fire support for the landing force.

Although the Ocean and the Ocean are also battleships, there are great flaws in the original design, the age of the ships is more than 15 years, and they have long been outdated models. But now that he has 8 battleships, he has taken prisoners, so these two battleships can naturally take a back seat.

However, as a fire support warship for the bombardment of the opposite shore, these two warships are qualified, because these two warships are equipped with three twin 280 mm main guns, the original four main guns at the beginning and tail are 35 radial times, and the two main guns in the middle are only 30 radial times, so the six main guns can not use the same firing unit, but when the East China government remodeled these two warships, the front and rear main guns were replaced with 30 radial times, so that although the power has decreased, the same firing unit can be used for salvo fire, and the actual combat efficiency has been improved。

If the Ocean and the Ocean can be said to be unsatisfactory, then the four Zhenyuan-class ironclad ships are the last bit of residual value, originally these four warships have basically reached the retirement period, and have been delegated to the reserves, but the East China government sent troops to participate in the war, and it was the time to use the ships, so these four warships were reorganized into active service and assigned to the Marine Corps. However, these four ironclad ships can still be used as floating batteries on the sea, and they have played their due role in the three previous landing operations of the East China government.

Of course, these six warships can complete the task of fire support, and the escort is a little inadequate, although the firepower and armor can still fight, but the speed is too slow, the Ocean and the Ocean are only 16 knots, and the four ironclad ships are even 12 knots, and Japan also has two armored cruisers, both of which have a speed of more than 20 knots, so the Navy will pull out the newly established 2nd armored cruiser detachment to the landing fleet, which can not only participate in the bombardment and fire support on the opposite shore, but also escort the landing ships.

In addition, there were detachments of 5th and 6th cruisers, 2nd and 4th destroyer detachments, as well as 8 landing ships, 8 troop carriers. Two warships will be dispatched, the Xiangyang and Huaihua.

It turned out that after the occupation of Shanghai, Luo Yue was thinking about the battle plan for landing in Japan. Although the purpose of this landing operation was not to occupy, it was different from the landing operation in Zhennanpu, which was to withdraw after the battle, and only stayed on the Korean Peninsula for more than 10 days, and this time it was necessary to fight on the Japanese mainland for at least about 6 months, and in addition, this landing operation was mainly to destroy, and it was also necessary to plunder Japan's wealth and population, so it was very important to choose the landing site, not only to be suitable for landing operations, but also to be conducive to defense, to establish a temporary forward base, and to have enough space to accumulate looted goods. population, etc., as well as troops temporarily stationed, preparing to land in other areas,

Japan is a country with an extremely long coastline, so there are many suitable places for landing, but it is difficult to choose if it is also conducive to defense, and there is still plenty of space. In addition, there is actually another condition, that is, it must land on the main island. Japan is an island country, the main body is four large islands, Honsu Island, Kyushu Island, Shikoku Island, Hokkaido Island, of which Honshu Island is the largest, accounting for more than 6 percent of the whole area of Japan, Japan's major cities, industrial areas, commercial areas more than eighty percent of the island, so only landing on Honshu Island can cause enough threats and blows to Japan.

However, Luo Yue believes that it is possible to consider landing in an area similar to the peninsula, and that the narrow terrain of the peninsula can be used to arrange a defensive line, and as long as the road leading to the peninsula is guarded, then there is enough space to set up forward bases, and the environment of the peninsula surrounded by the sea on three sides is also conducive to the fire support of the landing force by warships at sea.

The coastline of Honsu Island is very tortuous, and there are many peninsulas, so after screening by Luo Yue and his staff, it was finally determined that the Noto Peninsula and the Izu Peninsula were the most suitable locations.

The Noto Peninsula is the largest peninsula on the side of Honshu Island on the Sea of Japan, located in the north-central part of Honshu Island, the whole peninsula is an inverted "L" shape, with a total length of about 80 kilometers, only 10 kilometers at the narrowest point, and no more than 20 kilometers at the widest point, the terrain is mainly shallow hills, which is very suitable for arranging position defense, while the Izu Peninsula is located on the Pacific side of Honshu Island, located in the central and eastern part of Honshu Island, about 240 kilometers away from the Noto Peninsula, with a total length of about 60 kilometers and a narrowest point of about 15 kilometers.

From the geographical point of view, the Noto Peninsula is located on the side of the Sea of Japan, close to the East China government, which is conducive to transportation and replenishment, but the disadvantage is that the surrounding areas are not developed, and there is a lack of large cities, so the People's Army will set the Noto Peninsula as a forward base, and it will be much more troublesome to attack and harass and plunder other places, but the difficulty of landing is definitely less.

On the other hand, the Izu Peninsula is about 500 kilometers long, but its strategic location is much better than that of the Noto Peninsula, because most of the major cities on the island of Honshu are located on the Pacific side, and the coastal areas within 100 kilometers of the Izu Peninsula include large cities such as Tokyo, Yokohama, and Shizuoka, and within 200 kilometers of Nagoya and Tsu City. However, because of this, the garrison of the Izu Peninsula is bound to be stronger than that of the Noto Peninsula, and the difficulty of landing is naturally greater.

However, in this way, the two candidate sites have their own advantages and disadvantages, so it is difficult to choose, and after repeated thinking, Luo Yue formulated a new battle plan, with the Noto Peninsula as the first candidate and the Izu Peninsula as the second candidate, this order is not either/or, but the order of succession, that is, Luo Yue's plan is to land on the Noto Peninsula first, and then land on the Izu Peninsula.

The advantage of this is that the landing on the Noto Peninsula is relatively simple and easy to succeed, and although the landing on the Noto Peninsula poses a relatively small threat to Japan, Japan cannot turn a blind eye; once the KPA successfully lands on the Noto Peninsula, Japan will inevitably dispatch troops to carry out an encirclement attack, and the garrison on the Izu Peninsula will naturally be relaxed, and it will be much easier for the KPA to dispatch a landing force to land on the Izu Peninsula. In this way, the KPA can echo and cooperate with each other on the two peninsulas and fight in tandem. Of course, the threat and damage to Japan is even greater. It's just that the Marine Corps alone can't complete such a large battle plan, and at least two more divisions need to be added. In addition, two crossing warships are needed to serve as command ships, because the fleet will be divided into two divisions and the strength will be dispersed, while the remaining two Japanese armored cruisers can still pose a certain threat to the KPA and need to cross the warships for early warning.

In the end, Luo Yue drew up a total of three battle plans, the first two of which were to dispatch only marines to land on the Noto Peninsula and the Izu Peninsula and then start operations, and the third was to hope that two more divisions would be added to land on the two peninsulas and launch operations at the same time.
