The warm sun shone on the calm and peaceful William Military Port, and the battleships returning from the voyage brought flocks of seagulls, and at the same time brought the heat and joy of the harbor docks that had been dull for many days.

At about 8 a.m., accompanied by Defense Minister Walter von Brauchitsch, Admiral Franz von Hipper, and dozens of government officials, President of the Federal Republic of Germany Eric Adrian boarded several old battleships docked at the harbor docks. While carefully observing the ship's internal and external layout and various weapon systems, he listened carefully to the detailed introduction of the federal navy's military history interpreter and naval commander Hipper. Eric asked the dismissals to be as detailed as possible, including the ships that had participated in the First World Naval War, and he emphasized that in addition to the few warships under construction, the history of the former empire's navy is like a mirror, which can correct and help the new federal government plan the country's maritime affairs in a more targeted manner.

Eric watched and listened carefully to their explanations.

The former German Imperial battlecruiser is a fleeting star in the history of naval equipment, which combines the firepower advantage of a battleship with the high speed of a cruiser, but because of the weakness of its own defense capability, it forms a unique Atlantic maritime ship. At that time, the main activity period of German battle cruisers was World War I, and the number of warships and strategic deterrence capabilities were far inferior to those of the British Royal Navy. The Battle of Jutland, despite the mutual losses, ultimately proved that the Royal Navy, although not further strengthened, was still not comparable to the German High Seas Fleet.

The Nassau-class battleship was the first class of dreadnoughts of the German Navy, the construction of which began in 1907, according to the hexagonal configuration of the front and rear and the side of the gun with 6 main gun turrets, equipped with 12 280 mm main guns, although the caliber of the main gun is slightly smaller than that of the Dreadnought, but the rate of fire is faster, making up for its small caliber and less layout. This hexagonal turret arrangement also made it possible to ensure that only 8 main guns could fire at the same time in the direction of each side of the ship, reducing the ability to control the opponent with firepower. Compared with other warships, the hull of this class of battleships was wider, and the weight of the side turrets also caused the warship to roll too much when sailing in wind and waves, and in order to cope with artillery battles within a kilometer, larger caliber secondary guns were later used, which was different from the battleships built by the British Royal Navy at the same time. In terms of power, due to the German Navy's lack of experience with large steam turbines, the Nassau class still used reciprocating steam engines, used coal-fired boilers, and had a top speed of only 19 knots, which was 2 knots less than that of the Dreadnought class. It was not until 1915 that the German Empire made major improvements to the Nassau-class boiler, using oil-coal co-firing. However, when the reciprocating steam engine makes the ship of this class move at a high speed, the power mechanism continues to reciprocate, causing the hull to tremble violently, so that it affects the aiming and shooting of the artillery. This class of ships adheres to the tradition of German warships to save tonnage to strengthen armor protection and damage resistance, and does not pay much attention to the seaworthiness and endurance of the ship.

World War I entered the critical year of 1916, in the Battle of Jutland, 4 Nassau-class battleships belonged to the second detachment of the first battleship of the High Seas Fleet, in a night battle, several battleships were slightly damaged, after the end of World War I, the relatively old Nassau-class battleships were not on the Allied extradition list, so some were partially retained, this is the battleship that President Eric is inspecting. Eric actually wanted to send him away, but Britain didn't want these guys who didn't even want a place to park.

The Moltke-class battlecruiser was only built at the end of 1908, and was improved on the design of the von der Tann battlecruiser, further enhancing the armor protection and firepower configuration, extending the bow of the hull to the stern, and then adding a turret in the stern, in a knapsack layout, using a 50 times caliber 283 mm main gun, close to the power of the British 12-inch caliber main gun, and lighter, reducing the weight of the warship itself. The main guns of the Moltke-class battlecruisers, which were sufficient in number and power to offset the gap between the caliber of the main guns of the early battlecruisers of the British Royal Navy, could pose a mortal threat to the fragile defensive armor of the British same type of battlecruisers, the two of the same type, the Moltke and the Goeben. After the outbreak of World War I, in the Battle of Jutland in 1916, the Moltke was part of the Franz von Hipper's battle cruiser detachment, and served as Hipper's flagship after the heavy damage of the flagship Luzzo, and was extradited to England after the war, where it was sunk by the Imperial Navy at Scarpa Bay.

Among them, the Goeben is a legendary battleship, which entered the Mediterranean Sea in 1912, and after the outbreak of World War I, faced with the siege of the British Mediterranean Fleet, the Goeben was forced to retreat to Constantinople in the then neutral Turkey. At that time, the British government was worried that Ottoman Turkey would join the Allies and detain all the warships under construction in the Ottoman Empire, and Germany immediately offered to sell the Goeburn to Ottoman Turkey in order to gain Turkey's favor. On August 16, 1914, Turkey officially purchased the battleship Goeben, and on November 2, it was incorporated into the Ottoman Turkish army, and the next day it joined the battle. The crew of this Turkish warship, which was all German sailors, was officially handed over to the Turkish crew after the war, and after the war fortunately avoided the extradition of the Allies.

The Moltke was named after Helmut Karl Bernhardt von Moltke, Chief of the General Staff of the Prussian State and the German Empire.

The Kaiser-class was a new generation of German battleships, construction began in 1909, and it was also the first battleship in the German Navy to use steam turbine power. The two main turrets in the amidships of the hull are arranged in a two-sided stepped manner, and the angle of the reverse firing of the main guns is higher than that of battleships with similar layouts, and the two main guns in the stern are arranged in a knapsack type. The protection design of the Kaiser-class inherits the tradition of German battleships focusing on defense, and the weight saved by the improved firepower and power system design is used to strengthen protection, and its protection performance is significantly improved compared with the previous German battleships. Ships of this class tried to install diesel engines, but eventually gave up because the diesel power technology had not completely passed the test at that time. Among the ships of this class, Frederick the Great was specially built as a special addition and served as the flagship of the German High Seas Fleet. In addition to this, the Caesar, Catherine, and the Regent of Luitpold are of the same class.

In the First World War, the Caesar-class battleships were incorporated into the third battleship and participated in the Battle of Jutland, and the Frederick the Great served as the flagship of the commander of the High Seas Fleet, Reichard Scher.

Eric Adrian touched these war-polished battleships with his hands, his heart was very complicated, for the new warships to be commissioned in the future, he had thought about whether to continue to use the names of those heroic battleships in the past, but he changed his mind considering the feelings of the majority of naval crews, he did not want those naval soldiers who had just healed their wounds to fall into that indelible shadow for a long time.
