The victory in the Battle of the Gulf of Finland established the Soviet Navy's supremacy in the Gulf of Finland, and at the same time demonstrated the Soviet Union's maritime and air power to the world. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

After this battle, the strength of the German Navy was not struck, the battlecruiser Gneisenau and the pocket battleship Admiral Schell were sunk, and the light cruisers Leipzig and Nuremberg, as well as four destroyers, were not spared.

However, this victory was not easy to come by, the Soviet Air Force lost hundreds of aircraft in the battle, and the battlecruiser Kronstadt was also damaged by multiple shells and needed to return to port for 2 months of repairs.

Fortunately, the loss of more than a hundred aircraft was nothing to the Soviet Union, after all, in this world, the Soviet Union's aircraft production has reached the level of 85 aircraft per day, and the loss of more than 100 aircraft can be made up in only 3 days.

After this war, Germany has changed its strategic deployment from an offensive posture to a defensive posture. They began to build fortifications around Finland, Poland, Western Ukraine, and Bulgaria in anticipation of future Soviet counteroffensives. At the same time, Germany also stepped up the exploration and exploitation of mineral resources in the occupied areas in order to provide more raw materials to support military production in the rear.

However, both the construction of fortifications and the exploitation of mineral resources require a large labor force at their disposal. But at that time, all the manpower of Germany was already used on the battlefield, or in the rear for industrial and agricultural production, and only prisoners of war and local manpower in the occupied territories could be used for these tasks.

Of course, the Germans went on the defensive not because they wanted to "defend their territory", but to accumulate forces and prepare for a new attack on the USSR while holding on to the existing chassis.

But before this offensive can begin, they will have to massively equip Daimler Panther tanks (VK3002 (DB)) capable of competing with T-34/85 tanks, and be armed with a sufficient number of Elephant tank destroyers and Rhino self-propelled anti-tank guns.

In addition to this, the Germans also did everything they could to produce more aircraft in order to make up for the gap in the number of aircraft between the Soviet Union and Germany.

When there were more planes and new tanks were installed, the Germans would launch a new offensive.

At the same time, the production and R&D departments on the Soviet side were not idle, and various factories were working to increase the production of munitions.

In this time and space, the production capacity of the Soviet Union was stronger than in our history, and the production of various armaments, munitions and means of transport in the Soviet Union was also higher than in history, and the speed of research and development was also faster than in history.

As recently as April 1942, Soviet SU-152, SU-122, SU-100 self-propelled guns/tank guns began production at the Leningrad Kirov Plant, the Novosibirsk Plant 179 and the Chelyabinsk Tractor Plant, while the T-44 tank completed testing work and began production at the Kharkov Plant 183, the Novosibirsk Military-Industrial Complex and the Stalingrad Tractor Plant.

Various design bureaus have also carried out work on new tanks and self-propelled guns, and the 520 Design Bureau in Kharkov has already begun to redesign the chassis of the T-44 tank, following Manturov's proposals, to bring the turret seat diameter to 1800 mm without affecting the armor protection and performance of the tank.

Of course, it is not enough to design the chassis alone, since the turret seat has been enlarged, it is necessary to have a larger and wider turret. The Kharkov 520 Design Bureau, of course, also thought of this, and in parallel with the design of the chassis, it was also designing a wider and larger turret.

At Manturov's request, the new cast turret was to have a hemispherical design, carry a D-100 tank gun of 100 mm caliber and have thicker armor (200mm front, 125-160mm side).

Such a request, in 1942, was a bit incredible, and when Morozov (tank designer) heard such a request, he also told Manturov that "this is an almost impossible task".

Manturov also understood that it would be difficult to come up with a turret that would have been available in 1949 in 1942, but it was not impossible. So, he gave the design bureau plenty of time and allowed them to design the turret not according to their own requirements.

Now that the chassis has been changed, the turret has been changed, and the main gun has also been changed, the appearance and parameters of this new tank will also change greatly, so it also has a new name - the T-54 medium tank.

The aircraft design bureau is also not idle, the Ilyushin Design Bureau is designing a new attack aircraft, designated Il-10.

This attack aircraft will use the newly put into production Mikulin AM-42 liquid-cooled 12-cylinder piston engine, equipped with two 23 mm Vya-23 cannons, two 7.92 mm shKAS air machine guns, which can carry four RS-82 rockets and 500kg bombs, and the rear turret is also equipped with a 20 mm Berezin B-20 machine gun for self-defense.

Two other design bureaus are also working on it: the Yakovlev Design Bureau is designing a long-range fighter called the Yak-3DD on the basis of the Yak-3, and the Lavochkin Design Bureau is also immersed in the design of the La-9 fighter.

While developing aircraft, the research and development of aircraft engines has not stopped.

After obtaining the British engine technology, the Klimov Design Bureau successfully solved a number of technical problems, which made a breakthrough in the development of the VK-108 engine.

The Schvetov Design Bureau is also working on the improvement of the existing Ash-82FN engine (the modified engine is designated Ash-82T), and on the other hand the development of a new engine, the Ash-83.

The situation is somewhat peculiar in the case of the Mikulin Design Bureau, which, after the completion of the work on the AM-42, began to develop an axial jet engine.

However, axial jet engines are very demanding in terms of manufacturing processes and raw materials, and the structure of the engine itself is also very complex, and the cost of development and production is also relatively expensive.

However, at that time, the industrial manufacturing process in the Soviet Union was still relatively rough, and the funds and resources available to the R&D department were not much, so it was not suitable for the development of this kind of axial jet engine, which was more expensive and required to manufacture the process.

As a time-traveler from the 21st century and one of the leaders of the Soviet Union, Manturov naturally saw this, so he focused his manpower and resources on the development of centrifugal jet engines.

The person responsible for the development of the centrifugal jet engine was none other than the famous Rurika Design Bureau. This design bureau, the first in the Soviet Union to develop jet engines, was headed by Arkhip Mikhailovich Rurika.

As early as 1938, Rurika had already developed the first centrifugal jet engine in the Soviet Union, the RTD-1. This centrifugal jet engine has a thrust of 5kN, which was quite advanced at the time.

However, due to lack of funds and the lack of attention to the development of the jet engine, the development of this centrifugal jet engine was aborted, and the Rurika Design Bureau was forced to dissolve in 1941.

It was not until the end of 1941, thanks to Manturov's efforts, that the Rurika Design Bureau was re-established, and the development of jet engines was continued.

Since then, Rurika, who has experience in the research and development of centrifugal jet engines, was appointed by Manturov to be responsible for the research and development of new centrifugal jet engines, which use centrifugal impellers as compressors, with relatively simple structures, suitable for making relatively poor materials, and relatively low requirements for production processes, and relatively low R&D and manufacturing costs, which are more suitable for the situation in the Soviet Union.

Therefore, the centrifugal jet engine has naturally become the focus of research and development at the moment, and the Rurika Design Bureau has naturally received more research and development funds and resources.

In order to allow the Rurika Design Bureau to obtain more human resources, Manturov even transferred some personnel from the Mikulin Design Bureau, the Klimov Design Bureau, and the Schvetov Design Bureau to the Rurika Design Bureau, in order to allow the Soviet Union to enter the jet age as soon as possible.
