"Take off."

A Japanese airfield near Shimen.

Following Ghana's order, six Type 99 twin-engine bombers slowly took off from Bei Ping Airport, circled in the sky, and flew in the direction of Zhizishan Bridge.

Looking at the six bombers that had departed, Garner looked at him with pride.

The Type 99 twin-engine bomber produced by Kawasaki,

The maximum level flight speed reaches 480 km, the maximum bomb load is as high as 800 kg, and the full load range is 1,000 km.

It is the latest and most advanced bomber in the Empire.

Production began in July, and only 10 have been produced today.

It was supposed to be sent to the south to bomb Shancheng, the core city of Fruit, but with the rise of Tubalu in North China, the base camp deliberately intervened and allocated the latest batch of thirty to the North China Front.

It was used to bomb the base area of the Eighth Route Army.

To this end, the Imperial Logistics Supply Department also specially manufactured a special 800-kilogram special aerial bomb for bombing the bridges and warehouses of the Tuba Road.

Of course

The new aerial bomb has not yet been transported, and is still being produced in the Empire's native factories.

Therefore, in this bombing, the six Type 99 bombers carried eighteen 250-kilogram explosives.

But it's enough.

Because this time it was the wooden Zhizishan Bridge that was bombed.

Although front-line scouts reported that although the Zhizishan Bridge is a wooden structure, it uses a lot of timber, and the wooden beam structure is strong enough to withstand the passage of heavy tanks.

But wood is wood after all,

A single bomb hit can destroy the bridge.

···

"The devil plane is coming?"

An hour after the takeoff of the devil's plane.

Zhizishan Bridge.

A telegram arrived at the 2nd Battalion of the New 1st Regiment stationed at the Zhizishan Bridge, as well as the Ma Rongshun Platoon of the Independent Regiment.

The observers deployed by the headquarters near the Devil's Airport immediately discovered the bomber that the Devil had taken off and issued an early warning.

Although I don't know the target of the devil bomber, I just order the air defense to be strengthened everywhere.

"Prepare air defense."

Ma Rongshun immediately led the whole platoon into the preset air defense position.

With the expansion of the Zhizishan Bridge, reinforced,

The number of fixed air defense positions responsible for air defense has also doubled, from the original 15 to 30 today, of which only five are mobile single tubes, and this cannot be increased.

But fixed, double-barreled heavy machine guns increased to twenty-five units.

That is, around the Zhizishan Bridge, a wooden bridge of less than 100 meters, there are fifty-five 12.7-millimeter barrels facing the sky.

···

Meanwhile.

On the highway from the Taihang base area to the southern Hebei base area.

"Hidden."

"Hide in place."

"Pull up the covert net."

Thanks to the abundance of shortwave radios, the convoys received the alarm in time and sought cover on the spot to conceal themselves, or pulled up camouflage anti-aircraft concealment nets to avoid the bombing of the devil's planes.

···

"There must still be fighter jets."

Just a few devil planes put the entire base area on full alert, and the suspension of all transport teams made Li Yunlong, who was far away in Yang Village, have a thought in his heart.

The Air Force is needed.

Even if a large number of anti-aircraft machine guns were deployed in various places, the total number was as high as 350 units, of which as many as 300 were double-barreled.

A few planes from the devil's area took off and flew towards the base area, not only putting the entire Taihang, Taiyue, and southern Hebei base areas on alert, but also concealing the six grain convoys on the highway from Taihang to Taiyue.

If there is not a night truck fleet,

The efficiency of grain transportation will be seriously affected.

Although the anti-aircraft machine gun position can block the bombing of key positions by the devils, it is obvious that it cannot stop the bombing of the convoy and the truck team.

In the future, as the scale of the base area expands, the demand for supplies increases, and one day, the truck fleet will need to transport supplies during the day.

And in the military materials, it is clearly written that the best air defense is a fighter.

But what · ·

Li Yunlong once again turned over the information book on weapons and equipment, and there was indeed a lot of weapons and equipment in it, including a large basket of advanced fighters, what is the strongest propeller fighter, and what is a supersonic jet fighter.

But at present, the only thing that can be exchanged is the two-wing transport plane Yun Wu.

"Fuck..."

The feeling that he could only watch and couldn't use it made Grand Master Li very unhappy, but when he put away the information, his eyes pondered, and he suddenly had an idea.

"What do you want to do?"

As soon as Zhao Gang saw it, he felt that Li Yunlong had a bad idea.

"Lao Zhao, you say..."

"Our transport plane, the mission has almost been completed recently, right?"

"Transporting silver dollars to the north, transporting talents from the north and Jinling will be based on the base."

"Transporting the trainees to the border area."

"Transporting silver dollars to Wutai Mountain and the Shaanxi-Gansu border area."

"I haven't had a mission lately."

Zhao Gang replied.

Limited by the number of pilots, although the independent regiment has twelve biplane transport planes, it can only have a maximum of ten in a single takeoff, although the headquarters has been trying to recruit pilots, but in consideration of safety and confidentiality, the new batch of pilots has not yet passed the audit.

So far, there are only ten pilots.

Fortunately, ten planes can transport fifteen tons at a time, or a maximum of eighty adults.

At the moment ten transport aircraft have completed their tasks.

Including two million silver dollars paid to American businessmen for the purchase of military machinery and equipment.

"What do you want to do?"

Zhao Gang continued to ask.

"I think."

Li Yunlong's eyes rolled:

"The anti-aircraft machine gun can only block the accurate bombing of the devil plane, but it is difficult to shoot down the devil plane."

"Indeed."

Zhao Gang nodded.

Air defense and air defense, ten defenses and nine air.

This is not an empty phrase.

Many foreign war examples have proved that relying on air defense weapons alone can only block or weaken the enemy's bombing, and it is very difficult to shoot down a large number of enemy planes.

"There's an old saying that the best offense is defense."

Li Yunlong smiled and said:

"So..."

"Hey, hey, hey..."

"Are you going to use transport planes, transport mortars, shell the airfields of the devils?"

Zhao Gang's eyes lit up suddenly.

He understood Li Yunlong's idea.

The biplane transport aircraft, although not combat-capable, has a strong transport capacity and can take off and land on a very complex ground if it carries a load of five hundred to eight hundred kilograms.

And the 82 mortar weighs forty kilograms, the 120 mortar weighs no more than two hundred kilograms, and the shells will not exceed eight hundred kilograms.

With a range of five to seven kilometers and high-powered shells, it is enough to threaten the devil's airfield.

"Hey, hey, yes."

Li Yunlong's tone was smug.

"What a good idea!"

Zhao Gang agreed loudly.

After getting equipped, Li Yunlong had more and more ghost ideas for fighting.

···

"Reach the goal."

Although the devil is very satisfied with the performance of the newly commissioned Type 99 twin-engine bomber,

However, due to poor engine performance and poor structural aerodynamics, after a full load, the cruising speed was less than 200 kilometers per hour, and after a full flight of two hours, six Type 99 bombers arrived over Zhizi Mountain.

This cruising speed is even inferior to the B17 four-engine bombers that the Americans have entered service with in previous years.

The Type 99 bomber, in terms of bomb load and range, can only be regarded as a light bomber.

"Lower the height."

Arriving from the mainland, the devil Shaozuo pilot in charge of the command naturally did not know this, and he proudly ordered the six cutting-edge bombers to reduce their altitude.

Over Zhizi Mountain,

Six Type 99 bombers, gradually reduced to altitude.

"500 meters bomb."

The devil commander continued to command.

At a height of 500 meters, the skill can avoid all the weapons of the Eighth Route Army, and it can hit the Zhizishan Bridge more accurately.

···

"Devil plane."

When Ma Rongshun saw the devil plane in the sky that had lowered its altitude, his tone was not the slightest nervous, but full of excitement.

"It's coming!

The machine gunner next to him was in the same tone.

"Ready."

Through the field call, Ma Rongshun gave the order.

Although walkie-talkie communication is convenient and fast,

However, at present, the walkie-talkie obtained by the regiment is only a company-platoon-level individual knapsack walkie-talkie, and its technology is only about ten years more advanced than the Motorola 300 equipped by the United States during World War II.

In the past decade, electronic technology has only improved reliability.

Unlike mortars, there is no generational difference in technology.

The handheld walkie-talkie is not equipped.

Therefore, it is always necessary to have a strong position, and the telephone is obviously better than the walkie-talkie.

With Ma Rongshun's order, thirty anti-aircraft machine guns with fifty-five barrels were aimed at the sky, and the ammunition man carried boxes of ammunition out of the ammunition depot.

The Heavy lifts the barrel of his gun and looks into the sky through a special anti-aircraft scope, placing the Devil plane, which is gradually decreasing in altitude, in the center of the sight.

"Twelve hundred meters."

Holding the binoculars and looking at the devil plane in the sky, Ma Rongshun calculated the altitude in his heart.

Measuring aircraft altitude is simple.

Similar to the thumb ranging method, the regiment commander has already obtained the performance and size of the devil's 99-type aircraft, Ma Rongshun knows it by heart, and through the comparison method, he can measure the height of the devil's plane.

The effective anti-aircraft range of the 12.7 mm heavy machine gun was 800 meters.

The terrain near the Zhizishan Bridge is relatively complicated, with mountains on three sides, although the bridge is nearly 100 meters long, but the structure is slender, and if you want the Devil 99 bomber, you need to reduce it to about 600 meters to bomb before you have a chance.

"Six hundred meters."

"Open the magazine and release the insurance."

"Fire."

When the Devil plane approached an altitude of 600 meters, the Devil Commander ordered the plane to unhook the bomb safety and prepare for bombing.

But Ma Rongshun ordered to open fire.

Knock knock knock ·

Thirty guns, totaling 55 12.7 mm barrels, with a density of nearly 10,000 rounds per minute, weaved a dense network of fire over Zhizi Mountain.

obscured the sky over the entire Zhizishan Bridge.

Thanks to a tracer bullet at intervals every five bullets, this net of fire is visible to the naked eye.

In the sky, it's beautiful.

···

The beautiful firepower net has the most beautiful perspective in the sky, but in the eyes of the devil, it is the most dangerous and terrifying web of death.

"Climb."

"Bomb dropping."

The devil commander was hoarse.

He didn't expect that the Eighth Route Army actually had anti-aircraft weapons, and there were so many of them.

Click··

One bullet after another hit the Type 99 bomber at an altitude of 600 meters, making holes one after another.

"Machine Three."

An inverted devil plane was hit by the engine and fell with black smoke billowing.

Boom··

The plane's fuel and bombs that had not yet had time to be dropped exploded on the ground at the same time, creating a huge cloud of explosion smoke. (End of chapter)
