Compared with the mediocre howitzer, the shape of the grenade surprised Hu Zhuang, Wang Shengrong and others.

The artillery shells used by the People's Army are mainly solid iron balls and scattered bullets, and there are chain shells on the navy's side, and the shape of this grenade is very strange, the body of the projectile is slightly the same as the solid shell, but a wooden butt is added.

Ye Liangchou explained that this wooden egg tray can prevent the shell from rolling unsteadily during the discharging process, if there is no egg tray, the friction between the shell and the inner wall of the barrel will cause the shell to roll, if the fuse is facing the burning high-pressure gas at this time, the fuse will be pressed into the bullet body and explode directly.

Knowing the specific situation of howitzers and grenades, Hu Zhuang, Wang Shengrong and others felt that this howitzer was relatively troublesome to fire, and the rate of fire was relatively slow.

However, they still have great expectations for this howitzer, a shell that can explode like a grenade, its lethality is much greater than that of a solid shell, a solid shell must hit if it wants to kill the enemy, and a grenade does not need to be so troublesome if it wants to kill the enemy, as long as there is an enemy in the area where the grenade lands, it can cause damage to the enemy.

After learning about howitzers and howitzers, the test launch is about to begin, and the "target" is a kilometer in front of the howitzer, where some "scarecrows" are placed, some of these scarecrows are wearing armor and shields, some are only wearing cloth clothes, and a few back planks are standing not far away.

The possibility of an accident with a howitzer firing a howitzer is slightly higher than that of the Franc cannon, Fang Nan and his party left the howitzer more than 20 meters away, came to a place with a bunker, and some of their men sent up a telescope, Fang Nan and his party held a monocular, ready to watch the howitzer test fire the grenade.

Ye Liangchou gave an order to the artillerymen in charge of the two howitzers, and the artillerymen immediately took action.

Calculate the distance to the target, cut off part of the length of the grenade tube, reload the ammunition, adjust the gun, ignite, fire!

Accompanied by fire and black smoke, two grenades flew out of the muzzles of the two howitzers one after the other, and smashed into the target at a distance of 1,000 meters in a parabola.

Rumble! Rumble!

The two grenades exploded before they hit the ground in less than a second, but it was a pity that the first test shot did not accurately hit the target, one was more than 30 meters away, the other was nearly 20 meters away, and even shrapnel flew to the target area, but there was not much power.

The first test shot did not hit, Fang Nan, Hu Zhuang and others did not care, especially the military high-level who commanded the war, they know all kinds of firearms very well, if you want to talk about accuracy, it must be the first tiger head gun, there are sharpshooters in the people's army, and all kinds of distances of several hundred meters point to where to fight.

The accuracy of the artillery is far from being comparable to the Tiger Head Gun, at present, it is enough for the artillery to be able to hit the shells into a general range, dealing with large targets such as enemy arrays and city walls, which still refers to solid shells, if you replace them with grenades, the accuracy is almost enough.

However, the first test firing did not hit the target, which made the artillerymen who operated the two howitzers very uncomfortable.

In order to facilitate the correction of the firing position of the two guns, the two squad leaders were also equipped with a telescope to observe the landing point of the shells through the telescope, and the artillerymen recalculated, fine-tuned the gun body, and loaded ammunition.

About three minutes after the first test firing, the two howitzers spewed out grenades again, this time one successfully hit the target area, and the other was only less than ten meters away from the target.

It was a relatively successful test firing, and seeing that a grenade successfully hit the target, the artillerymen finally breathed a sigh of relief and quietly waited for the next command.

Seeing that the howitzer successfully hit the target in the second test firing, Fang Nan nodded slightly, and Hu Zhuang, Wang Shengrong and others lit up their eyes, they felt that the shooting accuracy of this new artillery was quite good, and they actually hit the target in the second test firing.

Since a grenade successfully hit the target, Fang Nan and the others had to go over to see how the grenade hurt the "target", and took a carriage, and the group quickly came to the target area to personally observe the damage of the grenade to the scarecrow.

The grenade exploded in the target area, and some scarecrows were directly blown down and shattered, and the flying shrapnel pierced through the shield and armor, and several pieces of shrapnel were also embedded in the wooden planks a little farther away.

"This grenade has more explosive effect than four or five grenades." He Yan came to a conclusion after looking at the venue.

Grenades and grenades are not comparable, grenades can't be too heavy, a grenadier must carry at least four or five grenades on his back, the grenade will increase in weight and be more powerful, but the number of grenades will be reduced, and the grenadier will not be able to throw the grenade far, directly become a suicide weapon, and die with the enemy.

The firearms research institute does not need to care about the weight of the grenade, but needs to increase the power of the grenade as much as possible under the same volume, and can even make a larger caliber howitzer to launch a larger and more powerful howitzer.

Zhou Yi looked at the explosion effect of the grenade, and was already imagining the scene of the howitzer being used as a naval gun and firing grenades at the enemy ship, and one by one the grenades fell on the enemy ship and exploded, killing and injuring the enemy on the enemy ship.

A high-ranking KPA leader who only watched the two test firings of howitzers made a decision that their troops must be equipped with howitzers.

Compared with the high-level military officials, Fang Nan thought more, Fang Nan is ready to give the Firearms Research Institute a new task, improve howitzers, and develop light, medium, and heavy howitzers, which can completely replace the Tiger Head Gun and the Franc Machine Cannon.

In the experimental site, all the high-ranking military officials told Fang Nan, the teacher, that they all wanted howitzers, but howitzers have not yet been officially mass-produced, and it will take time from mass production to mass production.

After a brief thought, Fang Nan made a decision, first let the arsenal mass produce howitzers, and each department of the People's Army to test and train artillery for each of the howitzers produced, and the first unit to be equipped with howitzers on a large scale was set as the navy.

Muskets are the main weapon in the army, and the navy uses artillery as the main weapon, and the fighting people's army on land is strong enough that even if the Ming court is armed with millions of soldiers, the people's army can defeat it.

But the battle on the water was different, the People's Navy was too far away from the Ming Ting Naval Division, and the Navy urgently needed new weapons to narrow the gap with the Ming Imperial Naval Division.
