As a clone of the German Navy's elite battleship and the conscience of the Bavarian Navy Design Bureau, the St. Isterwan will naturally not explode like the British battlecruiser. Theoretically, the ammunition compartment of this battleship does not have the possibility of being killed in seconds. The thick side-string armor and horizontal armor form a tight armor box, and behind the upper armor there is a thick steel back plate to prevent the armor plate from filling or collapse. Both theoretically and in fact, it prevents the possibility of surface strikes causing the ammunition depot to explode.

What about underwater defense? The perfect 5-layer defense system, under the protection of tight empty warehouses-liquid tanks-empty warehouses and the armored partitions behind, as long as the luck is not particularly bad, for example, if two torpedoes hit a place, the underwater defense system will be destroyed and even water will enter, but the possibility of directly detonating the munition depot is almost zero. But how to say it? After all, the defense of San Isterwan is a little worse than that of Bavaria. (After all, where is the tonnage and cost?) So, in this battle, some accident occurred.

Just a few minutes ago, a 15-inch shell fired by Hinata changed the seemingly balanced situation. After flying over a distance of 14 kilometers, the shell entered water less than 40 meters away from Saint Istvan. When it entered the water, the shell's hood collided violently with the water surface. The conical hood broke into pieces, and the huge reaction force directly adjusted the shell's body. The shell began to continue to advance during the sinking process, stabbing at Saint Istvan like a torpedo.

Due to the long distance, the shell had bypassed the lower part of the side string armor belt of the San Istervan before hitting the target! Due to the cost issue, the underwater defense of the San Istervan did not tilt directly like that of Bavaria, and then went to the bottom of the ship! The only thing that can truly be called armor protection is the last lightning protection wall with a thickness of 50MM!

In terms of penetration, the shells are obviously several levels higher than the torpedo! The five-layer lightning protection system and thin steel plates used to deal with torpedoes are not very useful when facing the shells. The steel plate is too small in thickness and is only used to absorb the energy generated by the torpedo during explosion. To be bulletproof, let's wash and sleep! This 15-inch shell easily cut the hull plate like a knife and then continues to be layers of high elastic steel. Fortunately, when approaching the bottom of the liquid cabin, the unreliability of the British fuse saved St. Ister's case! This shell was detonated before it penetrated the outer lightning protection system completely!

Boom! The violent explosion inside the hull seemed to make the entire warship shake. Although the charge volume was far less than that of torpedoes, the destructive power generated was still not underestimated! Several nearby compartments were immediately sifted by surging tides and shock waves. Even though there were heavy oil tanks with a thickness of half a meter to absorb the energy generated by the explosion, some fragments with large initial velocities and large weight were still hit on the last layer of protection under the water of Istervan. Some armored connections could not bear it first, and cracks appeared on the next door, and then quickly tore them open under the action of high-temperature and high-pressure bubbles and water flows. Water flows poured into the ammunition depot at the bottom of the turret of St. Istervan. What is even more worrying is that the partitions of some compartments were directly bulging up by huge water pressure for several centimeters!

As for water inlet, it's even less difficult. This shell directly brought nearly 700 tons of water inlet to the St. Istvan! The entire lightning protection system was blown up by the detonated shells. After being hit hard, the St. Istvan, who was a little confused about the situation, could only immediately pull the smoke screen to avoid the opponent's subsequent attacks, and thus created an opportunity for the Hinata to support the British warships behind it!

Originally, at this time, the Hinata planned to support the Fusang battleship that was fighting fiercely with the United Power, but at this time, the United Power also pulled out a smoke screen. At the same time, several destroyers that had left before returned, which made the single-powered Hinata feel a little trouble. After all, in the battle just now, one of the Hinata's turrets was also stuck, and two other gun barrels were broken. The secondary gun corridor area was also penetrated by the opponent many times, and the 7 6-inch cannons on the side string were broken by 4. As for the 3-inch level anti-lightning gun with worse defense, it was even more dead. At this time, it was really a bit weak when encountering the destroyer.

Besides, Britain and Japan are allies after all. Seeing that allies are almost killed, it is always necessary to help! So, after communicating with the Fusang, after the former said it was okay and brother could hold on, Hinata decisively aimed the muzzle at the Austro-Hungarian fleet's quasi-fairmen behind! Of course, due to distance and angle issues, such shelling is more threatening than actual effects. After all, there are only 4 15-inch cannons with a shooting boundary. And there are 17 kilometers apart, and the speed change rate between the two sides is very large, so it is difficult to hit the opponent in a short time.

If you turn your eyes forward, although the battle between the United Power battleship and the Fuso battleship is not coming to an end, it is time to decide the outcome. The 10 15-inch L42 tubes are indeed not empty. The 330MM tilted 18 degrees of armor is definitely strong enough. Although there is a certain gap with the Bavaria, it is enough to put it in one battle. After rounds of shots, the United Power, which is obviously smaller, can finally not stand it.

After being washed by the armor-piercing bomb, the entire superstructure was in a mess, and the armor belt at the head and tail of the hull was penetrated many times. The structure of the main armor belt was quite complete, but the cracks left after being attacked by heavy artillery were still shocking. Although the United Power also paid the same heavy price for the Fusang, it has to be said that under the balanced RP, the United Power really couldn't beat Fusang! What's more, this time, it seems that the Fusang's character was superior.
