readx; In addition to the H model mentioned above, at the end of World War II, the mustachioed Führer added another type of super battleship program: the H-45 (1945 type) H44 final modification. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

This guy is like blowing up a balloon, with a design displacement of 588,000 tons and a maximum displacement of 822,000 tons.

The H45 super battleship has a total length of 762 meters1, a width of 127 meters, a freeboard of 15 meters, a draft of 27 meters, and a draft of 32 meters at full load. Ma Dan, look at this data, such a long size is the first in the Guinness Book of World Records in later generations.

However, there are such big guys in later generations, but the size is slightly smaller than H45, and the time is in September 1975, Sumitomo Heavy Machinery Sumihama Shipyard (now Yokosuka Works) in Yokosuka City, Japan, began to build the 480,000-ton Sea Giant (S-E-A-W-I-S-S-E-GIANT) tanker, which was completed in 1979, and it took a lot of time to complete. But at this time, the Greek ship king who ordered the ship went bankrupt and resold it to the Hong Kong ship king Dong Haoyun. After Dong Haoyun took over, he asked the shipyard to change the design specifications, lengthen the middle part of the Sea Giant by 80 meters, and add 87,000 tons of deadweight to reach 564,763 deadweight tons, making it the world's largest giant oil tanker.

On December 19, 1980, Dong Haoyun personally presided over the launching ceremony of the Sea Giant. The ship is 458.15 meters long (a world record) and 68.86 meters wide (about the width of a football field), with a total area equivalent to four connected football fields. The fully loaded draft is 24 meters 61, which is equivalent to 8 floors; As a result, it is not possible to pass through shallow waterways and call at the world's major ports, most of which have a draft of less than 20 meters. The cabin volume of the ship is 658,362 cubic meters, and it can carry about 4.1 million barrels of crude oil, which is equivalent to two 300,000-ton oil tankers. With a gross tonnage of 825,000 tonnes after payload, the Sea Giant is too large and requires special connection facilities to unload crude oil directly off the open sea. Sumitomo S-T-A-L-LAVAL-AP steam turbine with a total power of 50,000 horsepower and a speed of 13 knots. It has a high degree of automation and only needs 35-40 crew members to sail smoothly.

Coming back, let's continue to talk about the H45, which has a maximum range of 35,000 nautical miles // 20 knots, which can be called a big name in the forties of the twentieth century.

In addition, the maximum speed of this guy is 35 knots (the maximum range within this speed is 15,000 knots)

Among them, its armament is extremely staggering.

Main guns: Eight 800 mm cannons with 71 x diameter barrels, (two quadruple arrays)

Secondary guns: 12 52-double-barreled 406 mm guns (6 twin guns) (originally planned to use 530 mm naval guns, but cancelled due to excess firepower.) and thirty-six 150-mm guns with 60 barrels (12 twins)

Anti-aircraft guns: 36 65 times 105 mm guns, 96 83 times 37 mm guns, 240 65 times 20 mm guns

Shipside armor: two thousand mm

Deck armor: 250 mm on the upper deck, 406 mm on the armored deck

Main gun armor: 2,000 mm front armor plates, 1,200 mm side armor plates, 200 mm additional super-hardened armor bulletproof plates (with the effect of Japanese V-H armor steel)

Secondary gun armor: 625 mm (406 mm secondary gun), 150 mm (150 mm secondary gun)

Bridge armor: one thousand and a half hundred mm at its thickest point.

Number of carrier-based aircraft: It is estimated that there are about 180 large and small aircraft

It is known that in the Nazi Navy's Plan H, the mustachioed Führer once whimsically proposed to increase the caliber of the main gun to 800 mm, and this brain-opening idea almost frightened the designers to faint. Later, in view of the design difficulty and the course of the war, the first two warships of Project H only used fifteen-inch 380 mm guns. So, is an eight-hundred-mm gun feasible?

For everyone who knew about this plan in later generations, the feasibility of this H45 super battleship was still very small.

Let's start with the cannon itself. What is the concept of the 800-mm gun, everyone has seen the "Dora" train gun, and it is not something that ordinary countries can afford. The fact that Germany was able to create "Dora" shows at least one problem: the German industry at that time did and did have the ability to create an 800-millimeter gun that could be used in actual combat.

Let's talk about getting on board. The Bismark's hull design was supposed to accommodate a sixteen-inch gun, but the Navy adopted a more secure fifteen-inch gun. What does this mean? It shows that Germany still lacked mature design experience from 406 mm to 800 mm guns at that time, and even if it could be built, the stability and actual combat performance were unknown, and there were certain risks.

On the issue of the displacement of warships. To place an 800-millimeter gun, how big does a warship need to be? Iowa uses 406, with a displacement of between 65,000 and 70,000, and the 800 cannon is almost exactly twice that of Iowa, but it cannot simply be assumed that a displacement of 130,000 to 140,000 is needed simply according to arithmetic logic. There are two questions to consider here: first, how to arrange the 800-mm guns? If only one gun is installed, a displacement of tens of thousands of tons may be enough, but if you want three turrets in triple, that displacement is astronomical. Second, the recoil problem. I have seen a war documentary, that is, "Dora" opened the cannon, and the recoil caused the train cannon of thousands of tons to retreat by more than ten meters. Of course, the recoil of the guns on a warship is not the same as on land, and the sea itself is a good buffer. But think about how spectacular it would be for nine 800-millimm guns to fire a close-range starboard salvo. I'm sure that no warship in the history of mankind can withstand it, including the 100,000-ton American aircraft carrier, which is basically just an empty shell. How much impact does such a strong ammunition delivery have? I'm afraid that a 100,000-ton warship will immediately capsize on its side.

About the issue of berthing at the port. According to the above analysis, the displacement of a battleship with 800-mm guns was estimated to be at least two hundred thousand tons. For such a large warship, the width and draft are very amazing. Such a huge behemoth warship would certainly not be able to go through the Kiel Canal. (After the expansion of the Kiel Canal in 1965, it could only accommodate ships with a draft of 9 meters and a width of 40 meters, and the bridge clearance was only 45 meters.) If such a large warship had been built at that time, this canal would definitely not have been crossed! If you take the Elbe and stop in Hamburg, there will definitely be a big gap in the waterway (to defend against British ships and submarines), and it will also affect the safety of the port.

Uncertainty. The rate of fire of the 800-mm guns is extremely low, and the accuracy is unknown, and it is bound to be bombarded by the small-caliber (16-inch guns are also small-caliber in front of the 800-mm guns) naval guns, can they withstand it? If the warship is so large, the armor is proportionally so thick (Bismark main armor with three hundred and twenty mm), let's say six hundred mm or even more. With such heavy armor, not a single ship of the British Navy at that time could deal with it, and the torpedoes were probably useless. If the deck armor is also thick, will it be able to withstand the attack of aerial bombs? If this is the case, it will really be an "unsinkable" warship.

It is a pity that the raw materials and funds required for such a warship are very staggering, and I am afraid that it will not be completed until after the war. However, if it was this warship that participated in the Rhine operation, I am afraid that the history of the Atlantic naval battle in World War II will really be rewritten.

1. The 420 mm main belt with an internal inclination of 60 degrees covers 43% of the main protection section. The main horizontal armor of 320-260 mm connected it, which, together with the 500 mm transverse walls, became a turtle shell...... The turrets are built on this tightly sturdy tortoise shell, and even if the top is completely destroyed, the bottom will be fine, and it will still be able to return home......

2. The inward oblique of the main belt also makes the effective killing area of the bomb only 57% of the conventional arrangement, and the danger rate is greatly reduced.

Deal with threats from underwater.

1. The main armor belt naturally extends to 3.5 meters under water, and the torpedo that hits the waterline is basically ineffective.

2. Below, according to the ratio of H39 H44, an air chamber with a depth of 8.1 meters can be arranged, and a layer of 80-110 mm elastic steel plate is in the innermost, and it should not be a problem to resist 1000kg TNT.

3. Fill the air chamber with foam in advance, and the fish can also protect the precious buoyancy under the dome, and the boat will not be tilted into the water in the anti-fish area.

Full protection is not bulletproof, but it can maintain the integrity of the hull surface, especially the waterline. The Musashi's speed dropped from 27 knots to 22 knots due to the bomb-penetrated bow steel plate turning outward, and if the waterline had a layer of armor of tens of millimeters, it could pierce at most one hole.

The main oil tanks are arranged at the bow and tail, the whole ship structure is evenly stressed (the armor is in the middle), the buoyancy of the oil and water after the fish is not changed much, and the head and tail will not sink seriously.

The hull is capable of defending against the main guns of any new generation enemy ship.

The 420-mm main belt is inclined 60 degrees inward, which is equivalent to 55-18 degrees at the main engagement distance of 5-23 km, and the tilt effect does not disappear until about 28 km (calculated according to the angle of incidence of mark7), at which time the artillery power of the enemy ships also almost disappears.

Why aren't other BBs arranged like this? Because only h44 (h45) is conditionally arranged like this!

1. The H44 (H45) hull is twice as underwater as on the water, and it can also provide a freeboard of 7 meters. The dome armor, which is placed 1 meter above the waterline, protects the space for use at a height of 12 meters below, and only 6 meters is sacrificed on top.

2. H44 (H45) allows the dome armor (here as the main armor belt) to naturally extend to 3.5 meters underwater, solving the underwater bulletproof problem (it will be longer in H45).

3. The 47-meter width of H44 (H45) can provide an 8.1-meter-deep anti-fish air chamber. (H45 wider for deeper fish-proof air chamber)

These conditions are not available in other sizes of BBs, right? Such a defensive arrangement was tailor-made for H44 (H45).
