Army equipment is to meet the needs of war, but the ever-changing battlefield forms have different performance requirements for equipment. In this regard, the Equipment Bureau has always put the versatility and ease of production of armored vehicles in the first place in the design and selection of equipment in the face of the various performance requirements for armored vehicles put forward by front-line commanders.

This is also due to the support from the top.

Since the inception of the Panzer Forces, the Imperial Army has maintained the tradition of being armed with only two types of battle tanks, and all self-propelled guns and tracked armored vehicles have been developed on the basis of the chassis of the finalized mass-produced tank, which has also greatly simplified production and reduced the pressure on logistics.

Based on this principle, the various models of "tank destroyers" developed by the North German Army were discontinued after the merger of the Reich, and in the eyes of the Industrial Committee and the Army Armament Department, the number of equipment produced was more important than the performance requirements. At present, the production of tank models equipped by the armored forces has changed from the pre-war Type 95 and Shepherd Dog tanks to the current Hound and Cheetah types, and some Tiger heavy tanks continue to be produced, while the original Type 95 tank chassis is still being produced, mainly for modified self-propelled guns and tracked armored vehicles. Since the army is still equipped with a large number of Type 95 tanks, it is impossible to stop the production of engines, transmission systems, and suspension parts used for maintenance, but the original main factory has been transferred to other small and medium-sized factories.

As a "35-ton medium tank project" that began to be developed before the war, the weight of the Type 04 "Cheetah" medium tank at the time of finalization had exceeded 40 tons, which made the maneuverability of this type of tank barely meet the minimum performance requirements of 50 kilometers on road and 38 kilometers off-road required by the Army Armament Department.

The requirements of the Army Equipment Bureau for tank mobility limit the engine power-to-weight ratio of each type of tank to 15 or more. This is a very strict standard, which means that if a tank weighing 50 tons can pass the final review by the Army Armament Department, it needs to be equipped with at least one engine with a power of more than 900 horsepower, and with the requirements for reliability, this power requirement may be increased to more than 950 horsepower.

At the current state of the art, this is a very difficult standard to meet.

To some extent, the Army's requirements for the engine performance and volume of armored vehicles are even stricter than those of the Air Force. On the other hand, a diesel engine with the same displacement is always much less powerful than a gasoline engine, but it has the advantage of being smaller and torqueous much more than a gasoline engine.

Jinyang Heavy Machinery Company and Jiangxia Ordnance Manufacturing Company once proposed to replace the 620-horsepower diesel engine currently equipped with the Cheetah tank with an aero engine with a power of 900 horsepower, but they were directly rejected by the Army Equipment Bureau.

In terms of tank power, the Army Armament Bureau has always adhered to the principle of using diesel engines, and it is impossible to make changes easily.

Otherwise, the entire logistics supply will have to be chaotic.

Ling Wencha met with Vice Admiral Qin Jiasheng at the Jiaozhou base, and on the side of the desk of the commander of the naval submarine force of the Imperial Northern Fleet, with the help of several adjutants, he unfolded several huge drawings on the background wall made of a huge nautical chart, and showed the leadership of the navy several schematic diagrams of the newly developed ocean-going submarine structures.

The Submarine Command of the Imperial Navy is mainly responsible for the development and production of submarines, the establishment and training of submarine forces, but most of the operational command is assigned to the two major fleets in the Atlantic Ocean and the Indian Ocean and South Africa.

"This is our latest ocean-going attack submarine, supply submarine and transport submarine, as well as a light underwater high-speed submarine equipped with a Walter closed-cycle system turbine engine.

The construction of the latest SMU04C large ocean-going attack submarine of the Chinese Navy began in July last year. Due to the surface displacement of 2,400 tons, even with the latest sectional construction technology, the construction period will be about 11 months, and it is expected that the first 16 submarines of this type will not enter service until June this year.

The submarines are equipped with four Wuhu-style 2,600-horsepower 12-cylinder V-piston diesel engines, with a total power of more than 10,000 horsepower, allowing them to reach a surface speed of 23.5 knots, barely meeting the requirements of following the surface fleet. In particular, it is equipped with two 4,800 horsepower main propulsion motors, which enable this class of submarines to achieve a high speed of nearly 19 knots underwater, and after being equipped with a new type of enclosed lead-calcium battery, its underwater endurance and battery capacity have been greatly improved. In addition, it is equipped with two 16-tube 210mm rocket launchers, and its long-range ground attack capability is also greatly improved compared with the SMUXI.-C/40 submarine, which is currently the main force of the submarine force.

This is our Type 04C submarine, which is an improvement of the Type 05, the main improvement of which is the optimization of the underwater line type, the use of a fully enclosed bridge, and only two small parts of the upper deck are retained. The deck guns were eliminated, and only one twin 25-mm rapid-fire anti-aircraft gun and two 210-mm rocket launchers remained. In addition, the capacity of the battery compartment has been increased and replaced with a new type of enclosed battery.

The other is a new type of high-speed submarine. At present, the Imperial Navy has twelve light underwater high-speed submarines equipped with closed-cycle turbine engines in actual combat. However, since the "Jiangxia-type" underwater turbine engine is still in the experimental stage, these experimental submarines equipped with hydrogen peroxide fuel engines have a displacement of only about 300 tons, and can only operate in the offshore ...... at present."

Vice Admiral Qin's adjutant was introducing Ling Wencha to the main types of submarines at present.

War is indeed a special catalyst for the development of science and technology. In a state of war, a country's manpower and material resources are concentrated in the research and development of military technology, and the vast majority of outstanding scientists and engineers and technicians have been transferred to research fields related to military technology and industrial production, which has caused some industries that are not far from military technology to develop abnormally and rapidly.

For example, electronics, rocket technology, and nuclear technology.

Of course, the development of weapons and other military equipment technology is more obvious.

But Ling Wencha's purpose is the kind of ocean-going transport submarine that is like chicken ribs, and its displacement of 2,800 tons is what is needed to equip a long-range rocket launcher......
