readx; Standing on the top of the Qingdao Mountain Fortress, Chen Jingyun looked down at the Qingdao urban area below, and couldn't help but feel a feeling in his heart, in order to recover Qingdao, China fought a big battle with the German defenders in Qingdao, and the equipment of the Chinese Army in that battle was far from being as good as it is today, and there were not even many large-caliber artillery, and only the 75mm artillery that could provide artillery support was the 75 mm artillery of those divisions, so when attacking Qingdao Fortress, it was completely relied on the courage of soldiers to attack, in order to take Qingdao Fortress, At that time, the Chinese army paid the price of nearly 10,000 casualties.

Looking at Qingdao, which was recovered at such a huge price, Chen Jingyun naturally sighed in his heart.

"Since the resumption of Qingdao, our navy has been building Qingdao as the main base of the navy, and in addition to deepening and repairing the berthing area in the harbor, we have also repaired the coastal defense and land defense fortresses in the port area. A number of large-caliber guns were deployed in several land-facing fortresses, including four 155-mm cannons, eight 155-mm howitzers, and four 105-mm cannons. In addition to our newly deployed land fortress guns, there were two 210-mm cannons and three 120-mm cannons left over from the original German army. Vice Admiral Yu Wentao explained to Chen Jingyun the latest defense situation in Qingdao.

"The firepower of these heavy artillery in the direction of the land has exceeded the firepower of the Germans back then!" Yu Wentao continued to say that the Chinese themselves conquered the Qingdao fortress from the land, which naturally prevented others from attacking Qingdao from the land in the future, so the fortress fortress facing the land was not reduced, but strengthened a lot. In addition to the permanent naval sailors, there is also an infantry division stationed here.

In addition to the land defense fortress, the navy also strengthened Qingdao's coastal defense capacity, and strengthened and built the Huiquanjiao Fort, Qingdao Shannan Fort, Yamen Fort, Tuandao Fort and Taixi Town Fort. Since most of the coastal defense heavy artillery originally deployed by the German army here was destroyed by the Sino-British Combined Fleet at that time, these batteries were rebuilt, and the coastal defense heavy artillery used was also reinstalled. ”

"Combined, these coastal defense batteries have six 12-inch caliber 45 times the barrel of the giant cannon imported from the United States, in addition to the Shanghai Arsenal's own two 14-inch 45 times the barrel of the giant cannon, and two other gun mounts will also be equipped with 14-inch coastal defense guns!" Yu Wentao said: "After completion, Qingdao Fortress will have the strong strength of four fourteen-inch and six twelve-inch coastal defense guns, so that the coastal fire force is enough to keep it out even if the enemy's main fleet comes to attack!" ”

In the past few years, due to the lack of naval strength, China has relied on coastal defense fortresses to block the enemy's naval attack, especially the Yangtze River estuary and Qingdao have been regarded as key construction areas. Needless to say, the Yangtze River estuary, there is China's first coastal defense area, along the perimeter of Shanghai densely deployed a large number of coastal defense heavy artillery, the entire Yangtze River estuary around the many coastal defense batteries combined, there are up to a full six 14-inch cannons, in addition to 14 12-inch cannons, this coastal fire power is enough to be proud of the coastal fire power of other coastal cities in the world. In addition to these large-caliber coastal defense guns of more than 12 inches, there are also quite a few 8-inch and 7-inch and six-inch heavy guns. It was precisely because of the huge coastal fire prevention power of the Yangtze River estuary that during the two years of the Sino-Chinese war, the navy of Ben never moved the mind of coming to shell Shanghai.

As an economically strategic place, the Yangtze River estuary has deployed so many coastal defense heavy artillery, and Qingdao, as the main base of the Chinese navy, is not weak, four 14-inch guns and six 12-inch guns are enough to make any navy on the earth dare not approach.

You know, the caliber and quantity of these coastal defense heavy guns are slightly inferior to the main guns of battleships, but the coastal defense fortress guns on land have natural advantages over battleships, especially in terms of shooting accuracy and range, relying on the earth and shell observation points up to more than 100 meters, the accuracy of the coastal defense fortress guns on land is much stronger than the main guns of warships, and although the cost of coastal defense fortress guns is also expensive, it is much cheaper than the cost of battleships. A mutual blow under the same caliber between the two will definitely be a loss for the battleship.

Therefore, any admiral in his right mind, even if the enemy has a fortress gun that can threaten his own warship, will not easily risk approaching.

Before the naval battle in the East China Sea, the Chinese Navy has always been regarded as a weak side, in order to imitate the enemy's landing in the hinterland of China, the Chinese Navy has built a large number of coastal defense fortresses in various important coastal areas, including Weihaiwei, Guangzhou, Fuzhou, Lianyungang, etc., all of which have built a lot of fortress artillery, among which Guangzhou guards the mouth of the Pearl River and is the focus of the Beijing-Guangzhou Railway, so its coastal defense facilities are not bad, with four 12-inch cannons and two 14-inch cannons.

In addition to the lack of strength of the navy itself, on the other hand, it is also because there are many warships that have been decommissioned in recent years, and it is a pity that the main guns dismantled from the retired warships are directly thrown away. As for the part of the self-made coastal defense guns, except for the eight-inch coastal defense guns, which were ordered by the navy on its own initiative, the four self-made 12-inch 45-fold guns were the work of the Shanghai Arsenal, and they were a stage in China's development of large-caliber naval guns, and the same situation also occurred with the 14-inch 45-fold guns made by the Shanghai Arsenal. It is impossible for these caliber naval guns to be equipped with China's latest battleships, but the Shanghai Arsenal also needs to continue to develop technology, so it still tried to build a few sample guns for testing, and later found that the surname Neng was okay, so it added a few additional equipment to Shanghai, Qingdao and Guangzhou, the three coastal cities.

Britain, France, the United States, and other countries have moved the main guns of a large number of retired capital ships to land as coastal defense guns.

The Americans even plan to use a large number of mothballed 16-inch and 50-fold giant guns as coastal defense artillery, and they are much stronger than China in terms of losers and luxury.

"With the protection of these coastal defense heavy artillery, Qingdao can be protected from enemy attacks in times of war. Moreover, in wartime, the surrounding waters can also be laid with mines, and with the high-speed torpedo boats in the base, it is enough to make the enemy's fleet come and go! "Yu Wentao is full of confidence in China's coastal defense fortresses.

Chen Jingyun listened and watched, nodding occasionally.

"Look, Chairman, it's the Qingdao Navy Arsenal over there! Do you see that large dock, which is one of the two 50,000-ton docks in China, and the other is in the Jiangnan Shipyard. At that time, these two docks were specially invested in the construction of Yaodi-class battleships, and although those two battleships were not built, they have now become the construction docks of two Shundi-class battleships! Yu Wentao pointed to the vague shadow in Jiaozhou Bay in the distance and said to Chen Jingyun.

In fact, due to the distance, everyone can only see a vague shadow, for Qingdao Naval Shipyard, Chen Jingyun is no stranger, he personally approved this project.

Among the three major shipyards in China, Jiangnan Shipyard and Mawei Shipyard are shipyards with a long history, even if they have declined, but still have a strong technical background, especially Jiangnan Shipyard is more technically strong, including almost half of the construction of warships of the Chinese Navy, not only to build warships, but also to contract the construction of most of the civilian ships, it is not an exaggeration to say that a Jiangnan shipyard has supported nearly half of China's shipbuilding industry. Although the Jiangnan shipyard was strong in technology and large enough, it was vulnerable to threats in wartime because it was in Shanghai. What is more important is that the navy does not want to see only one shipyard dominant, and the navy wants to support several shipyards to compete with each other, so as to avoid that the Jiangnan shipyard will not even have a place to repair ships after being bombed and damaged by the enemy during the war. In this concern, in addition to continuing to support the Mawei Shipyard, the navy also placed orders for a number of warships and auxiliary ships for the Huangpu Shipyard, which was jointly invested and built by several big capitalists in the southern part of the United Nations, in an effort to build a shipbuilding base in Guangzhou. In addition, the navy did not expect to rely entirely on private forces, but after consulting Chen Jingyun, the navy invested in the expansion of the original Qingdao naval ship repair base into a large-scale shipyard.

Qingdao Shipyard was originally the Navy's ship repair station, before also built some auxiliary warships, but mainly to maintain and repair a large number of warships of the Navy, now after increasing investment in expansion, with the support of the Navy itself, in one fell swoop to become the top shipyard in China, but unlike Jiangnan and Mawei and Huangpu Shipyard, Qingdao Navy Shipyard is not open to the public, they only build warships and repair warships, and do not accept orders for civilian ships.

Among China's many capital ships, Qingdao Shipyard participated, such as the second ship of the Shiguang-class heavy cruiser and the Hengshan-class aircraft carrier's lead ship, the Hengshan, both of which were built at the Qingdao Naval Shipyard, and now the Qingdao Naval Shipyard and the Jiangnan Shipyard have received orders for one Shundi-class battleship each.

"What is being built in the dock now is the battleship Zhuan, which started three months later than the Shundi at the Jiangnan Shipyard, and started construction in March last year, but the progress of construction is not much slower!" Yu Wentao continued: "According to the continuation of construction, if the follow-up funds can be successfully guaranteed, the Shundi at the Jiangnan Shipyard can be completed around November next year, and this Zhuan will be completed in January of the following year." ”

"Oh, this construction speed is still quite fast!" Chen Jingyun originally thought that these two battleships would not be completed until the second half of 1927, but he did not expect that they would be completed by the end of 1926 and the beginning of 1927. It seems that he still underestimated the capabilities of the domestic shipbuilding industry.
