Iron-blooded Hero Li Yunlong

Li Yunlong was taken aback for a moment, because he felt very strange when he heard the name, after all, he had never heard the name of the cannon Katyusha!

However, Li Yunlong has the skill of an encyclopedia of military arsenals in his mind. As long as he searches with his consciousness, he will soon be able to query a lot of materials and information about Katyusha.

The Katyusha multi-rail rocket launcher was the first self-propelled rocket launcher mass-produced and put into use by the Soviet Union during World War II.Compared to other artillery pieces, this multiple rocket launcher can quickly dump a large amount of explosives on the target, but it is less accurate and takes longer to reload.

During World War II, the artillery was basically two-wheeled, and it was rare to move a shell on a car. This Katyusha multi-rail rocket launcher can bet a large amount of firepower at one time, and left quickly before being counterattacked.

It can be said that the Katyusha multi-rail rocket launcher was a very famous artillery during World War II.

"Such a powerful cannon?" Li Yunlong was overjoyed when he saw the cannon rewarded by the system: "As long as you have this cannon, it will be easy to capture Nanjing City."

The official model of the Katyusha rocket launcher is BM-13, which is a multi-track self-propelled rocket launcher.There are 8 launch rails in total. One salvo can launch 132 rounds of 16mm caliber rockets, with a maximum range of 8.5 kilometers. It can be fired single-shot or partly in bursts. It takes about 5-10 ammunition to load a salvo. Minutes, a salvo only takes 7 to 10 seconds.The speed of the carrier vehicle is 90 kilometers per hour.

This gun has ferocious firepower and a wide range of damage. It is an effective weapon for destroying the enemy's dense troops in a large area, suppressing the enemy's firepower system, and destroying the enemy's fortifications.

The diameter of the Katyusha artillery has reached 132 mm, the weight of the projectile is 42.5 kg, the muzzle velocity is 70 m/s, and the maximum range has reached 7900-8800 meters.

.......

"Good guy, with this cannon, I can stand up to an artillery regiment!" Li Yunlong was excited: "And it's a moving artillery regiment!"

The arsenal system rewarded Li Yunlong with the Katyusha cannon and informed Li Yunlong of his address, then fell silent.

At this time, Zhou Weiguo looked at the strategic deployment map of the Japanese and puppet troops in Nanjing sent by Zhang Zuoguang, and looked at Li Yunlong and said, "Master, is this map still useful? Since he pretended to surrender, this deployment map is probably fake!"

"Not necessarily!" Li Yunlong said: "In order to win our trust, maybe they will give us a real defense map!"

"Then should we attack now?" He Jun looked ready to go, "Our soldiers' guns are already hungry and thirsty!"

"Don't worry, you go and get a secret weapon I prepared first!" Li Yunlong said: "With this secret weapon, taking Nanjing is like entering your own home!"

The secret weapon Li Yunlong mentioned is the Katyusha multi-rail artillery!

Katyusha multi-rail artillery!

This is the secret weapon artillery rewarded by the system. This time, attacking Nanjing will be even more powerful!

Immediately, under the benefit of Li Yunlong, several engineering soldiers found the Katyusha multi-rail artillery in the suburban jungle outside Nanjing and fired it back.

Zhou Weiguo, Lei Zifeng, Li Dabenshi and others looked at this Katyusha multi-track artillery, and they were all amazed.

"It's really a good idea to mount the artillery on the car!"

"There are so many tracks for artillery, it should be able to fire in bursts!"

"It's amazing, it's amazing just looking at this artillery!"

"With this artillery, it is certainly not a big problem to capture Nanjing."

……

The Katyusha multi-track fire "[-]" gun is composed of a car part and a launch part.The launching part is composed of a slide rail bed, a gun mount, a turntable, a chassis, an aiming device, and a launching device.The cartridge part is composed of seven tubular launch cartridges, and the firing wheel of the launch device is installed in the cab of the car.

It was the first time for everyone to see such a cannon.

"Okay, no need to guess his power!" Li Yunlong said: "You will know his power later."

The attack originally scheduled for the morning was postponed until noon due to the arrival of Zhang Zuoguang and Katyusha's multi-track artillery.During this period, Li Yunlong quickly taught the artillery to use Katyusha multi-rail artillery.

At this time, Wang Mingguo, Dongxiang Pingran, Lao Wang and others in the city were very anxious, because they didn't know the situation of Zhang Zuoguang's false surrender.

Now the Japanese and puppet troops in the city have basically lost contact with Zhang Zuoguang outside the city, because Zhang Zuoguang does not have a radio station to contact the city.

"Your Excellency, Commander, Commander Zhang hasn't sent the signal yet, so let's wait!" Wang Mingguo looked at Dongxiang Pingran and said, "I believe this is a perfectly designed fraudulent surrender!"

Dongxiang Pingran hesitated for a moment, then looked at Wang Mingguo and said, "Commander Wang, is your army reliable?"

If the false surrender becomes a real surrender, it will be a huge blow to the Japanese and puppet troops in the city!

"Don't worry about this!" Wang Mingguo said confidently: "Tuan Zhang has been with me for a long time, and his loyalty is beyond doubt!"

Dongxiang Ping Iran nodded and said nothing more.

12:00 noon.

The city of Nanjing is still peaceful, but this is only the eve of the storm.

At this time, all the fighters in the encirclement of the Jagged Sword Master were ready and ready to go. As soon as an order was given, they would immediately launch a fierce attack on Nanjing City.

Guanghua Gate, this is the main gate of Nanjing City, and also the main position for attacking Nanjing City.

12:10 minutes.

"Dong dong dong..."

"Whoosh whoosh..."

Under the firing of an artillery regiment and Katyusha multi-rail artillery, the shells began to tilt towards the tower of Guanghuamen.

Angry roaring artillery fire!
