When the US withdrew from the battlefield, they had lost a large number of M79 grenade launchers and M203 launchers.
And now, it was obvious that these grenade launchers were all obtained by the Vietnamese Army.
At this time, Li Weiting directly picked up the M79 grenade launcher from the wooden box and said,"
"According to the news from our recon company's soldiers, the enemy has already arrived. This grenade launcher looks like a shotgun and is very powerful. At that time, the company commander was directly hit by a shell and the flesh on his back was completely torn apart…"
" Under the suppression of the firepower, we tried to counterattack with grenades, but found that the grenades could not reach the enemy's firing point at all..."
Sun Hang stood up from his seat and said,"
" The effective throwing distance of the grenades used by our army is within 50 meters. The closest throwing distance of the 60mm mortars is at least 400 meters…"
" In other words, there's a blank area between 50 meters and 400 meters in front of us…"
"On the battlefield now, this blank area is sometimes very fatal.”
Li Weiting's eyes lit up when he heard the words 'firepower blank'.
He was a veteran soldier. After hearing Sun Hang's data, he immediately saw the weak point between 50 and 400 meters. No powerful firepower could cover it.
Sun Hang continued,
" The M79 and M203 grenade launchers have a maximum range of 400 meters, which makes up for this gap in firepower…"
Hearing Sun Hang's explanation of the M79 and M203 grenade launchers, Li Weiting's face immediately flashed with joy.
"Sun Hang, since you are so proficient in the M79 grenade launcher, can you make a batch of it as soon as possible and hand it over to the battlefield in the southwest…"
"Of course, our soldiers also saw the M203 grenade launcher that you mentioned. It would be even better if we could make this. After all, the M203 doesn't take up a lot of manpower.”
When Li Weiting heard the description of the soldiers, he immediately thought of Sun Hang's research on the Piquetini system.
As long as Sun Hang could develop a grenade launcher and hang it under the Piquetini system, he could launch the grenade directly.
It was convenient and efficient!
Sun Hang lowered his head and looked at the M79 grenade launcher in the wooden box, as well as the launcher that Li Weiting mentioned. Then he shook his head slightly.
Seeing Sun Hang shake his head, Li Weiting's eyes immediately froze.
In the next moment, Li Weiting's body shook slightly and he sat down powerlessly.
The reason why Li Weiting came to find Sun Hang in such a hurry was because he was in a hurry.
The M79 and M203 grenade launchers have caused a lot of trouble for our army on the battlefield.
In fact, just as he was on the way to the Red Star Military Factory, he received news from the military that the captain of the reconnaissance company had died in the line of duty due to heavy injuries.
Li Weiting could imagine that if the Vietnamese army found out that the M79 and M203 grenade launchers were so useful, they would definitely take out all the standard equipment in the country and put them on the battlefield.
Then, more and more soldiers of the Dragon Country would definitely be threatened by the M79 and M203.
At this moment, Li Weiting heard Sun Hang's voice above his head,
"The M203 grenade launcher has a huge flaw. It's not accurate enough and is not suitable for our country.”
" Although the accuracy of the M79 is decent, it can only fire a single shot. Under the circumstances where the formation is occupied, it's impossible to complete a rapid shot…"
" If we want to do it, we'll make a more advanced multi-shot grenade launcher that suits us…"
Sun Hang naturally knew that the rifles used by American soldiers would be equipped with grenade launchers. When the rifles were equipped with grenade launchers, they could flexibly use the active rifles to shoot according to the situation on the battlefield. They could also use the mounted grenade launchers to attack.
Moreover, this grenade launcher did not occupy the infantry platoon. Individual soldiers could use grenades to attack the enemy.
However, the Dragon Country did not adopt such a plan later on because the precision of the grenade launcher was not high enough and the recoil was too great.
When he heard the name of the grenade launcher, Li Weiting's face suddenly flashed with confusion.
Sun Hang explained directly,
" There's no need for us to make the M203. Although the M79 is excellent, the warhead used is a mechanical impact fuse…"
A trigger fuse was a fuse that used contact with the target to control the ignition. It was also known as an " impact fuse " or " impact fuse."
Sun Hang thought for a moment and said,"
" And the warhead we want to equip is best to use a radio proximity fuse…"
Radio proximity fuze was a foreign term to Li Weiting.
After all, most of the artillery shells in our hands, including many mortars, were all mechanical detonators.
As if seeing the confusion in Li Weiting's heart, Sun Hang continued to explain simply,
"Mortar shells or howitzer shells, because of the center of gravity, most of them will land directly on the ground.
This gives the mechanical fuse of the warhead a chance to detonate…"
"As for the radio proximity fuze, it was actually used in the early days when anti-aircraft artillery was used to hit aircraft in the air.”
" If we use a machine to detonate the fuze, when the cannonball can't hit the plane or it passes through the space next to the plane, the cannonball will be useless…"
"The radio proximity fuze will carry a device that continuously emits electromagnetic waves at the warhead.”
"The radio proximity fuze works based on the Doppler-effect of radio waves. The radio proximity fuze was equivalent to a radio transmitter and receiver. The transmission and reception of the radio used the same antenna, and the projectile usually acted as the antenna.
The fuze constantly emitted electromagnetic waves of a certain frequency.
When the projectile is within a certain range of the target, whether it is on the ground or in the air. Due to the Doppler-effect, the frequency of the electromagnetic waves received by the fuze was greater than the frequency of the electromagnetic waves emitted by the fuze itself. There was a frequency difference between the two. Eventually, it would become a voltage pulse.”
"When the accumulation exceeds a certain threshold, it will explode when the shell is within a certain distance from the target.”
Sun Hang knew that in the 21st century, modern anti-aircraft artillery shells were programmed to detonate on the basis of radio proximity bombs, and their attack and interception capabilities were even higher.
Later, radio proximity fuzes were also used to detonate targets on the ground and on the water.
Although Sun Hang tried to explain it simply, Li Weiting was still confused.
He only nodded blankly.
No matter what Sun Hang said, it sounded very powerful.
"Sun Hang, I'll leave this multi-shot grenade launcher to you. Don't worry, the organization will allocate the research and development funds to the Red Star Military Factory as soon as possible..."
"If you have any problems in your life, you can bring them up to the organization as soon as possible. The organization will not treat you badly…"
Sun Hang was now the director of the labor service company and the deputy director of the Red Star Military Factory.
His salary had already exceeded 100 yuan a month.
During this period of time, Sun Hang had been busy everywhere, and he didn't even have a place to spend money.
Moreover, the warehouse of the Red Star Military Factory was filled with various materials that were obtained from the transfer of gear hobbing machine technology from other military factories.
Sun Hang didn't spend much money on his own.
He could only express his gratitude to the organization.
When Li Weiting returned to the National Defense Science and Industry Department, Sun Hang directly gathered the high-level research and development team of the Red Star Military Factory.
Zheng Shan immediately said,
"QLB06 Grenade Launcher project approval, Sun Hang, as the chief designer.”
" Hu Qinghe will be the deputy designer, and the other higher-ups of the Red Star Military Factory will be the team members. They will be at Sun Hang's disposal at any time…"
