Zhong Bin was not originally a qualified naval officer, but he was also an old pirate who had been rampant in the South China Sea for many years, and he was familiar with the various forces in the South China Sea, and was familiar with the various ports and smuggling dens along the coast. Therefore, after a group of non-PLA Navy enthusiasts led by Yang Junbo unanimously demanded that Zhong Bin be released and put in the Navy for controlled use after systematic training, and after being criticized, Zhong Bin "deeply realized the crimes he had committed, changed his mind, and atone for his past sins with practical actions in the labor camp, with an excellent attitude", so the Senate decided to release Zhong Bin after a hearing of the Navy elders and grant him the status of a naturalized citizen. Based on his experience in commanding the fleet, he was directly awarded the rank of second lieutenant in the navy, and after a series of course training, he was re-placed on his former ship "He Lao Liu", but at this time this ship was named "Chunxiao" by the command of Dongfang Port, because this is the first ship of the Senate Navy, this name also means that this will mean that the Senate naval power will gradually grow like mushrooms after a rain.

Yang Junbo is a lover of ancient warships, and he has several examples of formation battles in ancient naval battles, although some of the battles in this new time and space have not yet happened or will not happen at all, but it does not prevent him from teaching the following batch of reserve naval officers as an instructor. Because the textbooks such as the T-shaped horizontal head described in his lesson plan are basically copied from the old time and space, in order to prevent the indigenous students from questioning the origin of the Senate, his students can only be senators. So Zhong Bin, who passed the naval officer training at this time, did not know Yang Junbo.

Zhong Bin saw Yang Junbo stretch out his right hand, and hurriedly reflexively saluted a military salute, "Good chief!" ”

Yang Junbo was a little embarrassed, and hurriedly returned a salute, and then shook hands with Zhong Bin. "Welcome to the Chunxiao patrol ship." As he spoke, he pointed to the boat path under his feet, "Familiar, right?" It's still your boat, but we've modernized it, changed the rudder device to a steering wheel, and changed your hard sails to soft sails, so you should have read the textbooks. ”

"Yes," Zhong Bin hurriedly straightened his waist and replied, "Although the soft sail is not as good as the hard sail in terms of bearing the wind, it is very convenient to retract and release, and it is easy to repair if it is damaged in battle." He looked left and right for a moment, and asked quietly, "Chief Yang, is there no cannon on this ship?" ”

"Ahem" Yang Junbo was embarrassed again, "The artillery is still in production, and your previous artillery is completely unusable, so it was unloaded, and it will be sent over after the artillery factory is made." ”

The artillery before Chunxiao was cracked and porous, and if it was fired, there would definitely be an explosion accident, so they were all sent to the metallurgical department to smelt, but at this time, Li Jin was still in the formula of the metallurgical department to mix smelting materials, and it was impossible to provide steel that could withstand huge chamber pressure.

"So what if you encounter an enemy at sea?" Zhong Bin didn't care about this, he knew that these patriarchs had good things in their hands, and on the day they were captured, they had seen large and small iron ships, and they had seen huge trebuchets and scorpion crossbows, even if there were no cannons, they would not suffer any losses, but at this time, there was nothing on the Chunxiao.

"First of all, this as a training ship, primarily for the training of sailors and officers of sail ships, we will not participate in naval battles; Secondly, there are spring cannons on the Chunxiao, which can have a range of 400-700 meters, which is enough for self-protection. Yang Junbo explained with a smile.

Well, this spring cannon is the PIAT anti-tank gun used by the British in World War II. It has a thick spring in the launch tube, which can be prepared by holding the launch tube up and pressing down the spring, but because this thick spring is so powerful, it often takes two or more people to press the spring into place. Because the loading process is very similar to firing a crossbow, it has earned the nickname "the bow of the Senate". But this spring cannon is not all fired through the spring, the function of the spring is only to fire the fire cap at the tail of the shell, and then the shell rotates and throws out of the launch tube, and then the propellant at the tail of the shell will be ignited by the fire cap, and then fly out, through the tail spin to maintain the stability of the trajectory, until the fuse of the warhead is hit and explodes. This copy of the PIAT is different from the original version of the British, the length and caliber of the barrel of the spring cannon are far beyond the PIAT, the caliber reaches a full 100 mm, and the charge is increased, after all, the explosive power of the black powder is far inferior to that of TNT, at this time can only be increased by increasing the amount of charge to make up for the lack of explosive power. The shell body is cast iron, and the less qualified products in the metallurgical department are used to make spring cannon shells, and the fuse in front of the shell is actually a large spring fire cap, because the material of this small spring is not up to par, resulting in an explosion due to a slight impact in addition to being placed upright, so the projectile body and the fuse at this time are separated, and they are only installed when they are fired.

Originally, because of safety issues, there were many naval officers who suggested that it was better to use RPGs directly to replace the use of naval guns, but they were strongly opposed by a group of ancient warship enthusiasts, RPGs will spew out powerful tail flames when launched, and the diffuse smoke will also make it impossible to see the battlefield situation clearly in battle, and the advantage of spring guns is that they will not produce tail flames when fired, and there is no need to worry about burning sailors or igniting flammable items such as sail decks on narrow decks, And with this mortar firing method based on the principle of free bolt machine, this kind of shell can be projectile to a distance of 700 meters with relative accuracy, and no other naval gun in this time and space can have such a firing distance. Although the spring cannon used a very high spring force, requiring two or three people to load, and having a strong recoil when fired, these problems did not exist on the ship at this time. Moreover, this 90 mm artillery shell can reserve 500 rounds on this ship, which is enough to meet the needs of an artillery battle at the level of a fierce battle.

Zhong Bin had never seen the launch of the spring cannon, but when he saw Yang Junbo's understatement in front of him, he knew that it must be a powerful weapon, so he didn't say much, just followed Yang Junbo's hand and looked at the spring cannons on both sides of the hull. Then he looked incredulously at the two "cannons" on the side of the ship, which were no thicker than his arm's thick.

"Chief, this cannon is too thin, isn't it?" Zhong Bin stepped forward and carefully inspected the cannon several times, and several sailors were scrubbing the cannon body with water. The thin cannon made him feel a little dazzled in the sunlight, "How far can this go?" As he spoke, he was still nostalgic for his guns, which could be blown up at any moment.

"Hey, hey!" Yang Junbo smiled darkly, this is a good opportunity to refresh the knowledge of the natives, and through the deterrence of the power of weapons, the natives can be more loyal to the Senate. "Artillery in a group!"

With the whistle of the ship's star officer, four or five soldiers in sailor uniforms rushed up from below deck and lined up on the deck to wait for orders.

"Goal! 450 meters away target ship, rapid fire two shots! Yang Junbo felt that he was possessed by Togo Heihachiro at this time, and pointed with his right hand to the target ship floating on the sea in the distance.

This target ship is a buoy with an eye-catching marker painted on it, which is used to test artillery on weekdays, except for the army artillery test site, which is used by the navy for artillery testing, and neither fishing boats nor cruiser destroyers will enter this area on weekdays.

The artillery group saluted Yang Junbo and Zhong Bin neatly, and then went separately, and the two soldiers went down to the cabin and took out the shell box and fuse box from inside, opened the box with a special crowbar, and then half-knelt by the box and waited for the shooting command. The other two soldiers opened the bolts of the gun mounts attached to the deck, put the barrels upright, and tugged at the spring handles in the spring guns. With a bang, the preparations for firing were complete, and the bombardier carefully assembled the fuse and shell, and then smoothly loaded the elongated tail into the barrel. The shells of the spring cannon are super-caliber, and the warhead at the front end has a diameter of 110 mm, and the spring is in place just enough to fit the tail of the shell.

After the shells were loaded, the gun commander carefully calculated the distance and elevation angle, and these gun commanders were all professionally examined, although the complex trigonometric functions could not be calculated, but there was no problem in calculating the trajectory with a set of formulas.

"Elevation angle 45 degrees! Aim! The gunner shouted out the data, and the loader adjusted the angle of fire according to the gunner's data, and then grabbed the arquebus in his hand and waited for the firing order. The PIAT is fired using a trigger, but due to the force of the 900N spring, it also requires a lot of force to fire, and the high recoil also requires the launcher to use more force to keep the launch tube stable. Therefore, the spring cannon is fired by pulling the fire rope, and the barrel is fired after being fixed, and it does not matter the influence of recoil.

"Launch!" The cannon commander gave the order loudly, only to see the launcher pull the fire rope violently, and with a "bang", the warhead was ejected from the launch tube, but with a pop, it fell directly into the sea less than twenty meters, followed by the heartless laughter of the army soldiers patrolling the shore.

"Meow's ...... Dud. Yang Junbo couldn't help grinning, although the military industry department assured him that the mute rate of this batch of super-caliber shells would definitely not exceed 1%, but during this period of live firing, he had encountered several such dud incidents, which made him feel quite unhappy. Thinking of this, he raised his right hand and waved it towards the target, "Keep shooting!" ”
