Three Gustav cannons are each responsible for a fortress, which is still much more efficient than three concentrated attacks on one.
And in terms of power, an 800-mm caliber Gustav cannon fired 7 tons of shells, enough to lift Lushun's fortress into the sky.
This thing can drill into the ground 30 meters deep with one shot.
Even the fortifications of the Maginot Line could not hold on, let alone these fortresses in Lushun.
An hour and a half later, the shells were loaded.
"Put!"
"Put!"
"Launch!"
The three cannons roared again, and one shell after another whizzed towards their respective targets.
The main fortress of Erlong Mountain, the main fortress of Pine Mountain and the main fortress of Baiyin Mountain North were all included in the target.
"Shelling!"
The whistling of 800 mm shells cut through the air, and the movement was still very large.
The Japanese troops in the fortress took refuge in the anti-gun bunkers inside the fortress, waiting for the shells to come.
In the main fortress of Erlongshan, the shell accurately hit the left half of the fortress.
The last part of this fortress is only 2 meters.
The penetration ability of giant cannon shells to reinforced concrete is 10 meters.
The exterior walls of the fortress were easily smashed through like paper paste.
After falling into the core of the fortress, the shell exploded.
200 kg of high-energy explosives exploded from inside the fortress.
The blaster of the explosion carries endless debris and harvests everything around it.
"Boom....."
Pieces of dirt splashed up, rushed into the air for tens of meters, and then scattered down.
More than two-thirds of the fort, which was only tens of meters long, was destroyed, and only the right part still stood on the hill.
A huge deep pit appeared on the mountain.
And all 4 150-mm howitzers arranged inside disappeared.
As for the two squadrons stationed on the fortress, they all saw their Amaterasu.
At such a close distance, there can be no living mouth within 100 meters, unless it is a very lucky few.
As a second-class fortress, the Pine Hill Fortress could not withstand Gustav's shot.
Although this shell missed a little, it also directly destroyed this small second-level fortress.
The fort, which was no thickest than 0.9 meters, did not hold the battery in the center of the fort.
The situation at the Silver Hill North Fortress was the worst.
A shell hit the door, and in the martyrdom of the shell explosion, the north fortress of Silver Mountain disappeared on the ground.
The casual company of the fort with the corpses of Japanese soldiers was scattered in the crater and the surrounding area.
After two rounds of shelling, only one lookout battery was left alone in the northeast fortress group of Lushun Fortress.
These three cannons came down, directly blinding the Japanese army.
Zhang Xueming, Huang Baitao and others still underestimated the power and accuracy of Gustav's giant cannon.
As the pinnacle of the German Third Reich, it can not be a flower shelf.
The siege ability of fortress fortifications is absolutely a transcendent existence.
"What? Super cannon? And still three doors? "
Lieutenant General Lin Xianzi, commander of the new Kwantung Army, widened his eyes when he heard this, and he looked very incredulous.
"Yes, Your Excellency, Commander, these cannons are so powerful that they destroyed our fortresses with one shot.
Judging by the craters on site, the caliber of these giant guns is at least 500 mm or more.
There must be a train cannon of the Northeast Army in the vicinity here. "
It took Lin Xianzhi a long time to digest the news.
Giant guns of caliber above 500 mm.
All the current fortresses in Lushun simply cannot withstand the cannon of this thing.
If they continue to fight like this.
Then in less than a week, not even five days, all the fortresses of the entire Lushun will be destroyed.
Without a fortress, how could they withstand the attack of the Northeast Army.
"How many fighters are left in our warehouse?"
Previously, Lushun had been subjected to air strikes many times, and their fighters did not dare to take off to intercept them.
So they chose to hide the fighter in the warehouse, ready to come in handy at a critical moment.
And now is the moment of truth.
"There are still 8 light storm fighters left, and 9 have been destroyed in previous air strikes and shelling."
Lin Xianzhi immediately said: "Do everything possible to find out those three giant cannons for me, and after nightfall, let Lu Hang destroy them at all costs."
Otherwise, the trip will be over. "
"Hi, Your Excellency Commander'.."
"Uh-huh....."
It was at this time that the bleak air defense siren sounded again.
Everyone couldn't help but tremble in their hearts after hearing this voice.
27 B-29 strategic bombers flew over the skies of the Lushun fortress.
There are also 40 P-47D Thunderbolt fighters involved in the escort.
The 27 B-29 strategic bombers targeted the northwestern fortress group of the Lushun fortress.
These two fortress belts are like a figure of eight, wrapping the port area of Lushun.
The northeastern fortress complex was manned by three Gustav and two K5 train guns.
The fortress group on the other side is put in charge of the air force.
Destroy the fortress complex in the shortest possible time, without giving the Japanese time to react.
Each of the 27 B-29 strategic bombers carried a modified goblet bomb.
Codenamed "Fortress Smasher" radio-guided bomb.
With the addition of a special radio kit, its weight has also been increased to 5.5 tons.
In particular, its tail section was fitted with 4 radio-controlled rudder surfaces and 8 flashes.
Compared to the original goblet bomb, if it is paired with a Norton sight.
For a target with a radius of 30 meters, its hit rate can theoretically reach 99.9 percent.
Even if it is a little worse in actual combat, its hit rate can reach more than 90%.
Against a ground-fixed fortress, it is a complete nemesis.
27 B-29 strategic bombers in three aircraft in one group, one group responsible for one target fortress group.
Sporadic counterattacks in the face of ground-based anti-aircraft artillery.
The P-47D Thunderbolt fighters involved in the escort swarmed down like sharks smelling blood.
This time, they are carrying aerial rockets and small aerial bombs.
It was used against Japanese anti-aircraft artillery.
The first to be attacked was the Erling Hill fortress on the northwesternmost side.
The fame of this fortress is arguably the most famous among the fortress group of Lushun Fortress.
Because this fort is located on the famous 203 Heights.
This is also the highest point of the entire Lushun Fortress.
In order to take this high ground, the corpses of the Japanese soldiers were covered all over the mountain.
So here they also deployed the most troops and firepower.
For guns above 75 mm caliber alone, no less than 20 guns are arranged here.
Fortifications were also built on the highlands and mountainsides.
These positions are linked together by bunkers, dark bunkers, and fortresses.
A wing of the First Division was responsible for stationing here.
"Air strike!"
"It was an air raid by the Shina people, and all the people entered the tunnel."
"Bang bang....."
An anti-aircraft gun began to roar.
But in the face of the B-29 strategic bomber flying at 8,000 meters, it is simply intentional and powerless.
Instead, their shooting revealed their position.
became a target for Thunderbolt fighters.
"Buzz..."
The door of the magazine opened to reveal a massive Fortress Smasher heavy drill armor-piercing bullet.
The bombardier controls the Norton sight and aims at the 203 Heights fortress below.
The guns placed on each gun battery in the fortress can be seen clearly through the scope.
When the lines of instruction coincided, the bombardier immediately pressed the bomb button.
"Oh it....."
As the hook fell off, the 5.5-ton ground-penetrating bomb fell freely.
Through the indicator light on the rudder face of the tail of the bomb, the bombardier fine-tunes through the joystick.
The aerial bomb that fell at such a very fast speed hit the center of the fortress group of Erling Mountain very accurately. (Read violent novels, just go to Feilu Fiction Network!) )
This is also the weakest point, with a flat concrete thickness of less than 0.8 meters.
For the Fortress Smasher Drill Bomb, which can penetrate 5 meters of concrete, it can be easily penetrated like paper paste.
Layer after layer of cement slabs were dropped, and finally the bomb settled at the bottom of the third layer.
The hundreds of soldiers located in the bottom bomb shelter looked at the smashed bomb in amazement, and their pupils couldn't help shrinking.
"Boom..."
The fuse was delayed, and the bomb with a charge of more than 2.3 tons exploded.
Its power is even better than that of Gustav's giant cannon.
The Gustav armor-piercing bullet has a charge of only 200 kilograms, while it has a charge of 12 times.
The entire fortress complex of Erling Mountain seemed to have been overturned.
In less than a second, two Fortress Smasher bombs fell again.
Two more extremely short explosions also detonated hundreds of shells in the underground ammunition depot.
The entire 203 Heights shook in this devastating explosion.
Mount Erling at the top of the mountain was easily destroyed like a volcanic eruption.
Even the splashed rubble flew out more than ten kilometers away.
This scene made the pupils of the Japanese soldiers of the fortress group on the northern front shrink.
Looking at the huge column of smoke rising from the 203 Heights, my heart couldn't help but be filled with fear at this moment.
What kind of power is this to form such a huge explosion.
"203 Heights is over."
This is the thought of all the Japanese troops who saw this scene.
At the same time, the bomber crew also had this idea.
Hit by such a powerful aerial bomb, even the fortresses of the Maginot Line could not bear it, let alone the fortresses of the Lushun Fortress.
I felt a strong tremor coming from the ground.
Lin Xianzhi knew that nine times out of ten, another fortress had been destroyed.
Sure enough, a call came immediately.
It brought him this extremely shocking news.
The bombers of the Northeast Army Air Force dropped three powerful aerial bombs, directly destroying the Erling Mountain fortress on the 203 heights.
From the magnitude of the shaking of the ground, he knew that this fortress must be finished.
It's really finished.
Shrouded in smoke and gunsmoke, a huge crater appeared on Heights 203.
The crater alone has a diameter of more than 40 meters and a depth of more than 20 meters.
Almost all of them bulldozed the 203 heights.
After the bomb drop was completed, the three B-29 strategic bombers began to pull back.
Today they also have three sorties to drop bombs.
According to the operational arrangement, each fighter has to fly four round-trips, two round-trips in the morning and two round-trips in the afternoon.
In their opinion, this is no longer a bombing of the fortress, it is simply to raze the mountains before they are willing.
No matter how strong Lushun's fortress is, it cannot withstand such an attack.
In about twenty minutes, 27 strategic bombers completed the bomb dropping mission.
Erling Mountain Fortress, Crow Mouth Fortress, Chair Mountain Fortress, Small Case Mountain Fortress, Big Case Mountain Fortress, West Sun Gou Fortress, West Sun Gou Fort, Sunjiagou Fortress, and Niujiaoshan Fortress were all heavily bombarded.
The Western Front fortress complex was basically destroyed by these nine fortresses.
Just one morning, with the cooperation of the giant artillery and the air force.
There is not one of the ten fortress groups on the eastern and western fronts of the Lushun Fortress.
This efficiency completely exceeded the expectations of the command, and also exceeded Zhang Xueming's expectations.
This also proves that the fortifications are completely outdated under today's combat methods.
Especially in the face of air strikes, it appears so vulnerable.
Lin Xianzhi felt that he was still too optimistic.
Not to mention five days, the entire fortress group of Lushun is estimated to be in three days to hold on.
He really didn't know if Zhang Xueming was a monster.
Where did you get so many heavy weapons specifically aimed at fortress fortifications.
In one morning, Gustav fired three rounds of shelling, and the Air Force made a total of 54 strategic bomber sorties.
Successfully destroyed the fortress groups on both the eastern and western fronts.
Of course, this only destroyed the surface fortifications between the various highlands.
There must also be remnants of dark fortifications and the like.
So the offensive remained in the afternoon.
However, this time the B-29 bomber group did not continue to carry the Fortress Smasher radio-guided bombs.
Instead, it carries a 500-kilogram bombshell.
Each B-29 bomber carried 12 bombs, filling the entire magazine.
A total of three B-29 strategic bomber groups and a total of 81 bombers carried out six rounds of carpet bombing of the ruins of the Western Front Highland fortress.
The First Fleet's side also stopped shelling after dusk.
Under the tireless efforts of the battleship Tarzan, the Des Moines class heavy patrol and the Cleveland class light patrol.
Most of the buildings in the port area of Lushun were destroyed by artillery fire.
In particular, 9 406-mm naval guns on the battleship Tarzan.
In total, more than 200 shells of 406 mm were fired.
Basically, the high-explosive shells of this level went down, and the surrounding area of tens of meters was razed to the ground.
A large number of Japanese soldiers hiding in the building suffered heavy casualties.
At nightfall, according to their statistical reports.
Not to mention the fortifications of the fortifications of Li Mozhao, the casualties alone amounted to 8,000.
That's a pretty scary number.
The strength of one brigade and regiment in one day, who can withstand this.
The success of the Lushun campaign also exceeded Zhang Xueming's expectations, and also exceeded Jiang Baili's expectations.
Mainly because they did not have a specific concept of the power of the goblet bomb and the Gustav cannon.
Otherwise, there would not have been a plan for shelling for half a month.
Look at the damage reports, assessments, and photographs that come in.
Jiang Baili sighed: "It seems that it only takes three days to destroy all the surface fortifications of the Lushun Fortress.
The power of this ground bomb and Gustav's giant cannon is simply unheard of and amazing. "
Zhang Xueming also nodded in agreement: "Don't talk about you, I was also taken aback by the power of these things."
Then let the brigade shunzhi shorten the shelling time, and launch a ground attack on the fourth day, trying to open a gap between the fortification groups on the eastern and western fronts. "
Jiang Baili nodded and said, "I think it's completely feasible." "
Suddenly he remembered something.
"Commander, the outside world is now very enthusiastic about our attack on the Lushun Fortress.
I've got dozens of calls from here alone. "
Zhang Xueming smiled.
"I think they want to see us deflated, but they may be disappointed."
The major warlords in the country, including the chairman of the Standing Committee, must not want to see their attacks go so smoothly.
They very much wanted to see themselves break their heads in front of the Lushun fortress.
But they don't know how long they have been preparing to conquer the fortress of Lushun.
With so many advanced weapons deployed far beyond the times of this era.
If you still can't get this Lushun fortress.
Then you have to reflect on whether you have made a mistake.
"Sign in."
When the time arrived in the early morning, Zhang Xueming directly started the new day's check-in.
Probably because of the war.
Today's check-in gave him a big surprise.
