The Northern Fleet's clean-up of the coastal defense batteries in Vladivostok went very smoothly, and after replacing the armor-piercing shells, the efficiency was at least 10 times higher than before, but in front of a small number of main batteries, there was a slight delay, and the rest, often one or two rounds of shelling, was cleaned up, and the combined power of the battleship's main guns and armor-piercing shells was satisfactory.

Cheng Biguang was very satisfied with the battleships under his feet, these battleships were a year later than Scheer's, and they looked almost the same, but in fact, they were different. Fantasy class and Orion reform, without the addition of new technology, only made simple adjustments, the first is the power system, newer power instead of the original power system, replaced with more advanced steam turbines and heavy oil engines, the overall power increased by 15%.

On a large warship like the fantasy class, the power is increased by 15%, which can almost raise the battleship to a higher level, in terms of mileage, speed, and even explosive power, there is a certain improvement, and the artillery has also been fine-tuned, or a 15-inch gun, the caliber has not been improved, but the multiple of the tube body has been increased from the original 47 to 52,5 times, and the penetration increase is at least more than 20%.

When developing a new, 52-inch naval gun with a caliber of 15 times, the cost was huge, even the Chinese Navy, which had deep pockets, could not bear it, and finally decided to fix the figure of 52 times the caliber, and the future 15 inches will be 52 times the caliber, and it will not continue to be improved, if it is raised again, the caliber of the artillery will be increased, and when the time comes. The new generation of capital ships will use a larger tonnage. Increase their power, this will also be what the entire Northwest will make. The last conventionally powered battleships.

In addition to the very critical place of these two battleships, the biggest improvement is the improvement of the armor, the materials science of the Northwest, which is almost the strongest discipline in the Northwest, itself has a certain foundation, and with the help of the all-in-one machine, a complete discipline has been formed, and the synthesis and analysis of the all-in-one machine are simply the biggest cheats for materials science. Even on the material, additives of rare earth materials are introduced.

It was not until after World War II, in the era of new materials, that rare earth materials will advance by leaps and bounds, and now they have begun to be applied to smelting, some additives and trace elements, and even a system, and therefore, the simplest armor has been completed. Even in the Yinshan base, the research on reactive armor of armored forces, although it is only a preliminary conduct, also represents a stronger direction.

Whether it's fantasy level. Or Orion changed, the overall appearance, there is no major change. However, there is a significant difference in combat effectiveness. At least on the main gun, 52 times the caliber is used. Combined with the increase in its strength, the power of the gun increases by 30%.

30% is nothing for a battleship, anyway, a 15-inch naval gun, under the premise of using tungsten core armor-piercing shells, except for the main armor belt of the fantasy class, the armor of any battleship can be torn, and an increase of 30% is not much different from no increase, but for land, it has a big effect.

Unlike battleships, land-based batteries can use reinforced concrete fortifications, some can reach 3 meters in a frenzy, or even more than 4,5 meters, under what circumstances, most of the naval guns need several times, or even more times to be able to pass through, which is also the reason why the battleship is powerless for land warfare, even if it is a higher grade, it also needs a lot of artillery, and if it cannot break the armor in a short time, then the opponent may be able to recover in a short time.

Any damage to the armor belt of the battleship must be replaced, but the artillery batteries on land, not to mention the reinforced concrete structure of the battery, can be quickly repaired, even if it is a temporary sandbag or the like, it can also provide a certain amount of protection, and this is the case here in Vladivostok at present.

But they didn't expect that the opponent's capital ship was a real 15-inch naval gun, which was not only powerful, but also increased the caliber of the barrel, increased the power of the gun by 30%, or the premise of using a tungsten core, on the homogeneous reinforced concrete fortifications. It can penetrate up to 4.5 meters, in this era, most of the fortifications can not block such an attack, even if it is impossible to penetrate all, but under two or three rounds, it is definitely penetrated, in this case, the naval artillery for the roadbed battery cleaning effect is very obvious, just half an hour of shelling, several forts around Vladivostok, have been cleaned up, revealing the main position inside.

Vladivostok's defensive batteries, which extend from the coastline, have been strengthened to a certain extent in the past six months, and the Chinese suddenly occupied Chita, showing their aggressiveness, although they did not believe that the Chinese would take the initiative, but it turned out that their idea was wrong, and the Chinese fleet not only came, but also almost destroyed the outer defense of Vladivostok.

At this time, the main officers of Vladivostok did not dare to stay in the peripheral batteries at all, the accuracy and sharpness of the Chinese fleet's artillery fire far exceeded their imagination, and the most important thing was that the several hidden batteries arranged in the periphery did not play any role, and were eliminated by the Chinese fleet in the periphery, little by little.

12 nautical miles away, has far exceeded the maximum range of the battery, even if the artillery is arranged on the main battery of more than 300 meters, it is only able to hit 12 kilometers, which is almost half of the difference with 12 nautical miles, which is equivalent to the battery in Vladivostok, a cannon did not fire, it was killed one by one, not to mention that Russian officers have never seen such a thing, even in the history of the world's military, there has never been such a big difference between land and sea.

Regardless of whether it can be defended or not, the main battery outside can't stay longer, the other party knows very well about the layout of the battery near Vladivostok, and the process of cleaning up is also very patient, even if it occasionally enters, it is far from the maximum range of the battery, let alone the effective range.

In the defense system of Vladivostok, the main highland battery is an important cornerstone, and it is almost impossible for the other side to let go of this battery, with the armor-piercing ability of the opponent's artillery, there is no position on this high ground is insurance, and no one wants to die before the division is launched, and all the senior officers of the Russian army in Vladivostok began to retreat from the top of the main highland battery.

In the headquarters, the officers of the Russian army had a grim expression, these batteries destroyed by the artillery of the Northern Fleet occupy the total number of batteries in Vladivostok, no more than half of them, which sounds like not much, but the batteries in Vladivostok have been accumulated over the years, and this half of the batteries already include most of the largest caliber batteries, if all the batteries above 11 inches are destroyed, Vladivostok's defense against the sea has been reduced to the extreme.

If you really count all the sea batteries in Vladivostok, if the Chinese fleet still maintains such efficiency, it is also very terrifying, this is only half an hour, according to the early time, at most ten hours, the entire Vladivostok will become an undefended city on the sea, unable to resist an attack from the sea. But what can be done? The enemy's firing range is far above the land-based battery, no matter how uneven they are, they can never increase the range of the shells, they can only watch, there is no other way.

"Perhaps, let the torpedo boats try it once!" The commander-in-chief of the fortress said tentatively, Wu Yangfu's expression was grim, of course he knew that if he continued, what was waiting for the Pacific Fleet would be a catastrophe, and the use of torpedo boats to impact was a helpless choice, and it was also a tragic suicidal impact, any ship on the other side had an overwhelming advantage over the torpedo boats, as long as there was any artillery fire of any size and fell on the torpedo boats, the torpedo boats would not be able to eat and walk around.

At this time, Uyangfu can't be conservative, the torpedo boat attack, this is also the way in the middle of the way, the Northern Fleet, the distance from the port is getting closer and closer, if the torpedo boat hits a round, it may have an effect, at least you can't let the other side keep getting closer.

The sounding balloon in the sky, coupled with the airship hovering at a higher position, in Vladivostok, no action of the Russian army could hide from them, and when the torpedo boats were ready and rushed out together, the Northern Fleet had already prepared and prepared the camp of anti-torpedo boats.

To deal with torpedo boats, the big ship is not easy to get, itself is in the depths of the port, protected by the battery, it is not easy to come out, if you want to come out, there are only torpedo boats, fantasy class and Orion change, the biggest effect is the command system, you can aim at multiple targets, heavy artillery accurate hits, so that the torpedo boats that were originally attacked by a numerical advantage were sunk one by one when they did not enter the range of the fish launch, and the torpedo boats were hit with the main guns, which is also unique in the world, one cannon and one gun, in just 3 minutes, The torpedo boats had already been cleared, but the nearest torpedo boats were still about 5 nautical miles away from the battleship, and the torpedo boats with more than 40 knots had no effect at all in terms of accurate aiming and the range of the capital ship.

A large number of torpedo boats were sunk one by one, directly dispelling the last resistance of the Russian Pacific Fleet, the strong strength shown by the Chinese Northern Fleet, so that the Pacific Fleet, in this battle, has never left the port, for them, leaving the port and the Chinese army head-on confrontation is dangerous, but if you don't leave, it's not dangerous, hiding in the port, the ship is hugging, but once the port is captured, the fleet will almost be completely captured, that is even worse.

From then on, the Northern Fleet began to eliminate land batteries at fixed points, completely cutting off Vladivostok's ability to defend itself on the mountain, and Vladivostok, which was heavily defended, finally revealed a flaw, and in the days to come, the flaws became bigger and bigger, almost laying the main tone of the war.
