Chapter 1062 Yongle Hongxi Xuande Cannon

Previous page        Return to Catalog        Next page

    It can only be said that the gap in strength between people is too huge.  When it comes to making guns and cannons, the brothers Zhao Shizhen and Zhang Jian can be said to be the strongest in the world.

    Of course, the fatherly Mr. Zhao can still point out the direction for his beloved disciple and nephew, so that they can avoid detours.

    In this era, there was a dazzling array of bronze cannons in Europe, ranging in length and thickness.  However, in view of the fact that in the next three hundred years, there was no essential innovation in the design and casting of bronze cannons.  It's entirely possible to look past these cannons with weird names and see what guns the British installed on their sailing battleships.

    Mr. Zhao activated his talent skill - Human Brain Search and found that the British fleet's naval guns on the battleships had not changed much in the past two to three hundred years.  Switch back and forth between the five calibers of 6 pounds, 9 pounds, 12 pounds, 24 pounds, and 36 pounds. No matter which caliber, the length is basically between 3 meters and 3.1 meters.

    In addition to these five types of long-barreled cannons, British ships will also be equipped with a carronade derived from mortars for close combat use.

    Therefore, the eldest nephew¡¯s task is simple but arduous - to build these five caliber long-barreled cannons and thick and short carronade cannons, and then finalize them according to the test conditions.

    At the end of the day, Mr. Zhao thought of the famous Napoleon cannon again, so he added two more types to Zhao Shizhen's list of cannons and let him slowly build them for fun.

    Six months later, Zhao Shizhen wrote a letter to report that ten of each cannon had been trial-produced and had passed a long period of test firing.  The conclusions reached surprised Zhao Hao. Leaving aside the carronade, the Napoleon cannon, whose gun body was only half the length of the long-barreled cannon, was not inferior to the British naval gun in terms of range, effective range and accuracy.

    This somewhat subverts Zhao Hao¡¯s understanding. Doesn¡¯t it mean that the longer the barrel, the more accurate it will be?

    It seems that the Napoleon Cannon is indeed the pinnacle of bronze cannons. It is powerful and fierce!

    ???????????????????????????????????????????????????????????????????????????????????????

    This is not difficult to understand. The length of the barrel of the front-loading gun is directly proportional to the difficulty of loading. The relatively short barrel of the Napoleon gun is of course very friendly to the loader.

    Of course, such rapid fire cannot last long, because bronze cannons are not heat-resistant and will become soft if fired too fast, but they are much faster than long-barreled cannons anyway.

    There is a more important point, that is, the same 12-pound Napoleon gun uses nearly half the copper than the British naval gun!

    ??~~

    In the naval battles of the Age of Discovery, there was no point in having a caliber that was too large. A larger solid shell could not cause more obvious damage than a smaller solid shell.  This has also been proven in Zhao Shizhen's report. The power of the 24-pound cannon and the 12-pound cannon are almost the same.

    Even the shooting accuracy is not important. Everyone is shooting close to the face anyway, so they can hit the target no matter what.  It can't cause any damage to warships beyond 400 meters. If Galen ships fire at each other, it's not too late to fire again within 200 meters The British only fire their guns within 100 meters.  They built the cannon longer in order to attack targets on the shore more accurately.

    So in naval battles, the most important thing is actually the rate of fire and the number of guns.  If my cannon fires quickly and in large numbers, the damage it will cause to you will definitely be greater.  This is the true meaning of naval warfare throughout the Age of Sail.

    Therefore, no matter from which perspective, the 12-pounder caliber, which is 117 mm, and the tube length is 14.3 times the caliber, which is 1.67 meters, is the best choice for the ship.

    After some weighing without much struggle, Mr. Zhao ordered that the Napoleon cannon be used as the main naval gun, and the first batch of 300 guns be produced, named Yongle cannon.

    ¡° Just consider that when the Marine Corps landed in combat, the gun body alone weighed 557 kilograms of a 12-pound gun, plus the gun carriage weighing several hundred kilograms, it easily exceeded 1 ton, which was too heavy to be used as a field gun.  Zhao Hao also asked Zhao Shizhen to build 100 6-pound, 93 mm caliber small Napoleon cannons, and named them Xuande cannons as secondary guns and field guns for battleships.

    In addition, 100 carronade guns with a gun length of 1 meter and a caliber of 145 mm were cast and put on board as fleet close defense and anti-personnel weapons and equipment.

    Zhao Hao named this thick and short cannon the Hongxi Cannon so appropriate.

    If nothing else goes wrong, Dahei, Fatty and Xiaohei are the three main gun types of the Sun-Tian fleet.

    ??~~

    That afternoon, Mr. Zhao inspected the construction project of Tamluo base without stopping.

    Compared with Xingang City, which has complex functions, the construction of the naval base is much simpler. The docks, windshields, military camps are currently concentrated near the military port.

    In order to accommodate the huge smuggling fleet, the seaport here is already too large.  The wind-blocking wall is also much easier to build than the breakwater, so the construction progress here is much faster than that in Xingang City.?, four thousand people didn't even cough.

    This is not easy, because among the 4,000 police officers, only 1,500 Coast Guardsmen were transferred from the security force and have undergone long-term and rigorous training.

    The remaining 2,500 people have been sailors on the Jiangnan Shipping Company for a few months.  In July, he was transferred to the garrison area and began to receive military training from Director Tong.

    Director Tong¡¯s power is boundless. In just two months, he has injected a lot of spirit into them. At least when they stand at attention and line up, they look just like the old police officers.

    Seeing this scene, Director Tong, who was holding a pitch black spiritual infusion stick, nodded with satisfaction.

    He didn¡¯t wear the outer cloak, revealing the slim-fitting dark blue large lapel, short hem and arrow sleeves.

    There are three silver ribbons on Yisa's arrow sleeves, which are the same as the three silver stars on his hat and helmet, indicating his status as a senior police inspector.

    Director Tong will also go out with the army this time, urging the new police officers to intensify their training while performing their tasks, and will inject spirit into them at any time!

    With him watching eagerly, who would dare to speak out?
