The first task Tan Renhao received was to draw up a wartime shipbuilding plan for the navy, and according to his tactical thinking, determine which warships should be built first, which warships should be delayed or even completely abandoned, and which new warships should be developed. In addition, the performance requirements of various weapons on the battleship, the combat objectives that need to be achieved, etc. This is a huge and systematic project, but Tan Renhao immediately knew that this was Nie Renfeng's trust in him, and it was also an opportunity for the principal to give him an opportunity to display his talents.

Tan Renhao first became familiar with the system of the relevant aspects of the navy. The Imperial Navy's pre-war shipbuilding system was relatively complex. First of all, the Naval Equipment Technology Office puts forward the performance requirements, and then the Navy Logistics Command issues a design tender to the major shipyards, and finally selects the most probable, and the most suitable performance and price from the design plans submitted by the major shipyards, and then determines the specific construction plan and issues a purchase order to the shipyard. I am afraid that it will take more than five years for any new warship to go into service from design to final service.

The wartime procurement system was completely different, with many aspects of the review process being eliminated. Directly by the Navy Command put forward the performance requirements of the new warship, and then gather the engineers of the major ship design institutes and shipyards to come up with an optimal combination plan, and then only conduct a feasibility assessment, after determining that such a warship fully meets the requirements in terms of performance, the construction task will be directly assigned to each shipyard, and the construction will start at the same time. And at this time, it is the performance, not the cost, that determines the battleship. Of course, it is no longer built exclusively by the shipyard that won the bid, but by all shipyards that have the ability to build it together to increase the speed of shipbuilding. And according to this method, a new warship will only need one to two years from the beginning of the design to be able to enter service with the Navy.

The difference between these two warship construction systems can be clearly seen. In peacetime, it is impossible for the Imperial Navy to build a large number of warships, especially battleships and aircraft carriers, which are generally only a few at the first level, and the requirements for speed are not very high. However, in times of war, the speed of construction, the performance of battleships ranked first, and all new ships were built in large quantities after it was determined that the performance met the needs. For example, during World War I, the Imperial Navy's cruisers and destroyers were ordered for dozens at one time, and the capital ships were also built at one time for more than a dozen ships.

Next, Tan Renhao spent two days familiarizing himself with the Navy's previous shipbuilding plan. And when he went through the files of those ship-building plans, his heart was also very uneasy.

Before Jiang Bangguo became the commander of the navy, Sajiting had drawn up a series of shipbuilding plans for the navy, the most important of which were two "Yangtze River" class aircraft carriers.

This is a new aircraft carrier of the first class designed in accordance with the new aviation tactical requirements of the Navy after summing up the problems exposed on the "Emperor" class aircraft carrier. And already before the outbreak of the war, construction began. Its main performance parameters are: the length of the ship is 245 meters, the width is 34 meters, the draft at full load is 8.5 meters, the flight deck is 240 meters long and 36 meters wide, and two catapults are installed. The displacement is 21,000 tons at light load and 24,500 tons at full load. 12 high-power heavy oil boilers were used, and the maximum speed reached 33 knots. The aircraft carrier has eliminated all sea-facing artillery, expanded hangars and ammunition depots, and can carry up to 100 combat aircraft if fighters are tethered on the flight deck. In addition, the aircraft carrier is equipped with more than 40 anti-aircraft guns, and the ammunition depot and fuel depot are designed with compartments.

In terms of performance, the "Yangtze River" class aircraft carrier is much better than the "Emperor" class, and it is completely designed in accordance with the standard fast fleet aircraft carrier, focusing on strengthening the aviation strike force, air defense combat force, and the survivability of the aircraft carrier after being attacked. Tan Renhao even got the blueprint for the design of the aircraft carrier, although he didn't know much about the design aspect, but he could see at a glance that this was the aircraft carrier that the Imperial Navy needed.

After Jiang Bangguo became the commander of the navy, the two aircraft carriers, whose hulls had been completed, were ordered to slow down the pace of construction, and the shipbuilding resources were first provided to the four battleships under construction. And during these months, the construction of the two aircraft carriers progressed very slowly, and little changed.

Tan Renhao felt extremely sorry that if the construction progress could be maintained, then in two months, the two aircraft carriers could be launched, and it would take about four months to complete the perching work, and they could enter the navy. Even if resources are reallocated now, it will take at least half a year to bring two aircraft carriers into service.

Tan Renhao didn't dare to delay time. Within ten days, he took out the plan that Marshal Nie Renfeng needed, although it was only a simple report on the needs of naval warships and weapons and equipment, but Tan Renhao almost put forward in the report the needs of everything from ammunition to aircraft carriers. Then, he personally went to hand over the report to Marshal Nie Renfeng.

Nie Renfeng read the demand report submitted by Tan Renhao very carefully, then took off his reading glasses, and his gaze stayed on Tan Renhao for two seconds before he spoke: "Renhao, do you know why I want you to do this report?" ”

Tan Renhao frowned slightly, but did not speak.

"Before, I was skeptical of your theories, to be honest, I always thought that General Liao Hanxiang had put many of our young officers on the wrong path, but now I think that your choice may be the right one." Nie Renfeng let out a sigh, and then walked to the window facing the harbor, "After Prime Minister Xue Xiyue asked me to be the commander of the navy, I looked for Marshal Sajiting, and at that time, Marshal Sajiting only recommended you to me. The result of the naval battle of Jeju Island, I am very clear, on the surface, the Fifth Fleet let the Japanese Southwest Combined Fleet escape, but in fact, the Fifth Fleet won a great victory, if there is no victory in the naval battle of Jeju Island, then now we have lost Jeju Island, maybe the Japanese Army has landed on the Korean Peninsula, the empire will be forced to fight a large-scale ground war with Japan, which will be a disaster for the empire. The resignation of Marshal Saditin was forced, the Imperial Navy took a detour, and also lost a large number of excellent officers and men, as well as battleships. We can't afford to do that anymore. ”
