Bright Sword: Follow Kong's fun and build the strongest military industry

Of course, grenades have to be filled with powerful yellow explosives. The old black powder grenades sometimes only had three or four fragments, or even exploded into two halves. If there were a small number of these things, they would not have much effect, but would instead cause heavy losses to the militia, whose combat effectiveness was not strong to begin with.

What's more, the operation of the grenade is very simple. Just take out the grenade, unscrew the lid, pull the trigger, and throw it towards where there are many enemies. That's it.

If you are lucky, it is no problem to kill two or three enemies with one grenade. Even the elderly and women can be used for defense, and you can even take a little Japanese soldier with you before you die.

Whether it will succeed or not depends on today's test results. If the expected effect can be achieved, it means that the strength of the Eighth Route Army will usher in explosive growth again.

At this time, at the arsenal weapons testing ground, grenades loaded with new explosives were ready and ready for testing at any time.

Because it is a newly researched product, its performance is definitely not that stable. It requires a lot of testing and the relevant test data must be recorded to provide a basis for future technical improvements.

Engineer Wu is the person in charge of this grenade test. This time he will give you a detailed explanation:

"Director Ren, Political Commissar Qin, Chief Advisor, the hand grenades we developed this time were based on the style of the Jin-made hand grenades, and combined with the current situation of our arsenal, we specially researched them."

"Through research, we found that the gunpowder we just produced was not as powerful as that produced by the Taiyuan Arsenal. In order to ensure the power of the grenades, we increased the amount of gunpowder in each grenade accordingly."

"In addition, two types of grenades were specially designed according to the needs of the battlefield. One is an offensive grenade, which is filled with 30 grams of new explosives. The whole grenade weighs 500 grams."

"The other type is a defensive grenade, which is loaded with about 80 grams of new explosives and weighs about 800 grams. It is very powerful, but it can't be thrown too far."

The people present were all veterans of the battlefield and were quite familiar with things like grenades.

Director Ren said loudly, "Xiao Wu, hurry up and test it. I can't wait to see how powerful our newly produced grenades are."

"The grenades produced with black powder in the past had poor explosive power, and the troops on the front line often cursed after using them. We are well aware of this. It's not that we don't want to produce such powerful grenades, but we simply don't have the conditions to do so."

"We finally managed to get some yellow explosives, but we can only prioritize the production of mortar shells. Grenades are too expensive, and our arsenal is also helpless without rice."

Following Engineer Wu's order, the observation bunker directed the technicians to conduct relevant tests through flag signals.

In fact, the testing method is very simple. It is to divide the test field into ten areas. A grenade will be fixed in each area, and then it will be detonated with a rope. The purpose is to test the time from pulling the ignition to the explosion of the grenade, and to collect data on the fragments produced after the explosion.

As the explosions rang out one after another, one could feel from the sound and movement that this newly developed grenade must be quite powerful.

About an hour later, all the data was counted.

After Wu Gong took the notebook, he read it out loud:

"Sample No. 22 is an offensive grenade. It takes seven seconds to explode, produces shrapnel, and has an explosion radius of six and a half meters;"

"Sample No. 18 is an offensive grenade. It takes seven seconds to explode, produces shrapnel, and has an explosion radius of six meters and two meters;"

"Sample No. 26 is an offensive grenade. It takes six seconds to explode, produces shrapnel, and has an explosion radius of seven meters and eight;"

……

"Sample No. 36 is a defensive grenade. It takes eight seconds to explode, produces shrapnel, and has an explosion radius of meters;"

"Sample No. 44 is a defensive grenade. It takes seven seconds to explode, produces shrapnel, and has an explosion radius of nine meters and two;"

"Sample No. 38 is a defensive grenade. It takes seven seconds to explode, produces shrapnel, and has an explosion radius of meters;"

……

After hearing these data, everyone present applauded. Although these data were slightly worse than those of the Jin-made grenades and Gong-made grenades, they had exceeded the expectations of everyone present.

Director Ren said happily: "Great, that's great. Now we finally have a hand grenade that's worth showing off."

"However, there are still some aspects that need to be improved, especially the fragmentation after the grenade explodes. It would be best if it could be stabilized at a certain value. There are still too many differences in our production. We need to put more effort into technical improvements in the projectile casting."

Kong Hao also added: "The detonation device has too much deviation in time. We need to make more improvements in this area. It would be best if we can control the time within seven seconds and use a standardized production model to ensure the quality of all parts."

"I'm sure you all know that in our frontline combat units, some soldiers like to pull the trigger on a grenade, hold it in their hands for about three seconds, and then throw it out to cause an air explosion, in order to kill the enemy to the maximum extent possible."

"Our military production departments must ensure the quality of weapons and never hand unstable weapons to the frontline soldiers. This is irresponsible for the lives of soldiers."

"Also, urgently produce 20,000 grenades, half for attack and half for defense, and send them to the front-line troops to see the actual effect. Some problems can only be discovered when they are used on a large scale, so we have to send people to follow up."

After hearing this, Engineer Wu quickly ordered someone to write it down and then arrange for its execution.

After Director Ren and Political Commissar Qin read it, they left as they still had a lot of things to do.

About half a month later, the new grenades produced by the arsenal were delivered to the front-line combat troops through various means of transportation.

At this time, the Second Battalion of the 771st Regiment was ordered to block the attack of a group of Japanese troops, just to cover the entire regiment in eliminating the four Japanese strongholds that had wedged into the defense zone.

At present, the Japanese have built artillery towers everywhere. Although the Eighth Route Army has obtained a large number of Type 92 infantry guns and artillery shells during this period, it is still seriously insufficient compared to the number of artillery towers of the Japanese.

To use the Type 92 infantry gun to attack the Japanese artillery tower, a well-trained artilleryman would have to hit it at least three to five times. If they were unlucky, even seven or eight shots might not be enough to destroy it.

It is only in the last two months that the various regiments of the Eighth Route Army have been equipped with some Type 92 infantry guns. In the past, if a regiment had two mortars, the regimental commander would have been happy. After all, even the famous Li Yunlong and his New Day only had one mortar.

Training a qualified artilleryman, especially a barreled artillery like the Type 92 infantry gun, requires a long time and a large amount of shells. This kind of thing cannot be rushed.
