Long Xiaotian in the tower couldn't bear the agitation in his heart. Even in the past few days, the steps of the "Tianlei" plan have been fully deduced many times, and even simulated tests of possible US interceptions and defensive measures. The final assessment result was that the probability of the success of the "Sky Thunder" program was as high as more than 90 percent. Even without considering the second plan, the success of the Lanfen alone is more than 75 percent.

In other words, before 1 a.m., there was a great deal of hope that the operation would be successful.

In order to monitor the course of this air raid, as early as a month ago, the Fifth Military Intelligence Department arranged multiple monitoring points within 100 kilometers of Oak Ridge. Agents in the MIA call this kind of mission dormant latent, that is, after receiving the mission and arriving at the predetermined location, it begins to hibernate. Use a possible measure to reduce the possibility of being discovered, and until the mission is completed, the radio will be activated to send out the information. And then...... Then it's time to run for your life. Of course, the Military Intelligence Agency will also arrange a number of channels in advance to help these agents hiding in enemy-occupied areas escape.

The same Colonel Zheng Yong, who had explained the situation in and around Oak Ridge in front of His Majesty, was the chief of the agents who commanded and monitored the "Heavenly Thunder" program. At the moment, she is at Ellington Field Airport, in a small two-story building, where the MI5 special operations team is ready. After midnight, they will turn on the receiving station and wait for a signal from the "dormant" agents.

At 23:41, the base tower received a report from the spiny dragon early warning aircraft: the coordinates were guided, and "Lanfen" was heading to the target in the right direction.

The hearts of everyone in the command tower were entangled, and the "Golden Weiyang Palace" between Long Xiaotian's fingers was even more smoky, and it hadn't moved for a long time. The good spontaneous combustion of the best tobacco ensures that the cigarette continues to burn silently, but after the spark, the gray ash still remains relatively flat, and when you look at it from a distance, it seems that it has never burned.

The second hand of the disc clock on the wall was clattering, but the damn minutes seemed to stand still, and twenty tiny squares were moving so slowly.

There was a sudden smell of burning in the command tower, and everyone's eyes turned to the only dragon general in the round tower who smoked and dared to smoke. The spark had already burned to the sponge of the cigarette mouth, and in fact, after the cigarette was lit, the Admiral took a total of two puffs.

An operations staff officer from the Royal Air Force Command glanced up, and it didn't move when it was staring at it just now, and the damn minute hand jumped to 23:55 all at once.

"Commander, there are five minutes to zero hour." The staff officer walked up to Admiral Long and reminded him softly.

"Oh!" Long Xiaotian, who maintained the posture of "thinker", responded, it seemed that he was a little tired after sitting for a long time, and he wanted to change his posture, but he couldn't prevent the cigarette butt in his hand that had burned to the end of his hand and immediately disappeared, so that General Long Xiaotian was suddenly in a hurry, but he still couldn't prevent Martian from falling on the sky-blue general's uniform and burning a hole.

"Damn, bad luck ......" As soon as the words came out, as if he had thought of something, Admiral Long immediately changed his words, "Burn well, burn prosperity!" ”

The sound of a room of jaws falling to the ground.

……

Ten minutes ago, when the AWACS aircraft sent back the last message, all combat units of the Royal Air Force had fallen silent. Even the four "Raptors" that took off with the "Lanfen" and the two "Spinosaurus" that carried out the guidance mission also turned off radio communications.

According to the plan, the radio silence ban will not be lifted until 0:30 a.m. on July 13. Before that, no matter what the course of the operation was, the only radio station that was turned on was the one next to Colonel Zheng Yong of MI5.

Of course, Long Xiaotian didn't want to wait until 0:30, because that would mean that the Lanfen's operation had failed, and it meant that he had to prepare for the execution of the second plan.

"In mortal life, you must succeed!" extinguished the sparks on the military uniform, Admiral Long walked to the floor-to-ceiling window of the tower, looking at the airport that had canceled the light control because of the "Sky Thunder" operation, whether it was the road or the apron, it was a bright light, "mortal life, as long as the news can be transmitted back in ten minutes, Lao Tzu decided to wear this military uniform in the future, and the hole in the front chest, just ask for a medal to block it!" ”

Silently reciting the name of the beloved general, Long Xiaotian made a "poisonous oath" that made people cry and laugh. However, to be honest, Admiral Long is indeed a believer, even after the war, at the grand wedding that caused a sensation in the whole alliance when Marshal Jiang Yunzhi married the Queen of Guoan, Long Xiaotian refused to change into new clothes, and still wore this old military uniform with a hole in it to attend. Until...... Many years later, in the Longxiang Palace, when His Majesty once again personally brought the "Golden Dragon Tuzhu" epaulette representing the Imperial Marshal, this shabby general's uniform with holes was exchanged by His Majesty for a case of good wine, and it was preserved in the Imperial Military Museum for a long time.

……

"The course is correct, it is close to the target, and it is still 260 kilometers away from the coordinate point of the bomb. At present, there are no suspicious targets within the radar alert range. ”

On the Lanfen, in the cockpit, the co-pilot and navigator Major Zhang Tiezhong, who was sitting side by side with the captain, Colonel Li Fansheng, had a deep but clear voice.

"The ignition device is docked, one qiē is normal, and the naughty baby No. 0004 can drop the bomb at any time."

Captain Ma Wencai, the weapons operator who was opposite the first two pilots, then reported! More depressed than the two pilots, the captain couldn't see the sky outside the plane at all from this position, and in front of him, there were always various instruments with the lights constantly flashing, and of course, those few vital weapon operation buttons.

The cockpit of the second-generation "Qilong" H-41B is quite quiet, and the automatic oxygen supply and on-board air conditioning can ensure that the temperature and humidity in the cabin are within the most suitable index range for human survival.

But Li Fansheng still felt sweaty in the palms of the pilot's thin leather gloves. You don't have to look back to know that the two brothers are in the same mood as yourself, they must be ten minutes of nervousness, and if you listen carefully to the report of the two of them just now, you can hear the trembling that they are trying to hide.

Ten minutes ago, after saying goodbye to the command of the AWACS aircraft and the other brothers of the 22nd Special Service Squadron responsible for escorting the convoy, the "Lanfen" had already begun to fight alone. As a strategic bomber, it is customary to penetrate deep into enemy lines, and carry out bombing missions without the escort of its own fighters.

Since the establishment of the strategic bomber unit of the Royal Air Force under the command of General Long Xiaotian, since the birth of the first long-range strategic bombing "Helleye" of the Empire, as one of the trump cards of the strategic bomber force, but the previous mission, which time was not a group of intensive bombing?

This is the first time that the mission was carried out in the rear of the enemy, which still has a strong detection ability and interception.

There are few men who don't like to take risks, but if you add eight words to the end of adventure, "Only success, not failure!" "Then it's not fun to have an adventure!

Fortunately, when breaking through the air blockade zone of the US military, the flight of the "Lanfen" was not disturbed in any way. Neither the radar detection on the ground nor the air patrol force of the US military found this flying wing bomber rapidly advancing at high subsonic speeds at an altitude of 15,000 meters.

Is it that the radar of the US military simply does not have the ability to detect multi-band compounds? Or did the U.S. military not send an air patrol squadron tonight after the toss of the day of the air armistice?

For these, Colonel Li was unwilling and did not have time to think too much. The confrontation between radar and stealth fighters is something that scientists should worry about, at least for now, this time the "Qiulong" can achieve a stealth breakthrough, then it is the best.

"Brothers, don't forget the time! We must wait after 0:5 to drop the bomb, otherwise our Commander Long will definitely curse! He'll say that our brother is deliberately trapping him for being unkind! ”

"Haha......" Knowing that Li Fansheng was deliberately joking to resolve everyone's nervousness, how could the other two not cooperate, but they laughed ...... The fake ones made them embarrassed to laugh anymore!

"Determine the coordinates again!" Realizing that this tension could not be resolved with a joke, Colonel Li immediately began to give orders for battle. Anyway, it's already nervous enough, so take advantage of the high concentration of the brothers' attention to make sure that the action is foolproof.

"The flight altitude is 15,022 meters, the coordinates are 542,613, the direction is correct, there are still one hundred and twenty kilometers from the target, and the time is 23:57."

The sky outside the transparent window of the fighter plane was full of stars, but the ground was pitch black. At such a time, the visual appearance has no effect, but the various instruments densely packed in the cabin are enough to show a qiē.

Li Fansheng did not speak, the distance of one hundred and forty kilometers is only a matter of a few minutes for the "Lan Fen" with a flight speed of more than 1,000 kilometers per hour.

Moreover, at the current speed, the bomb was dropped at exactly the same time as the scheduled time. In this way, Lan Fen does not have to waste time hovering too much in the target area. Without much confidence in this so-called stealth performance, Colonel Li did not think that it would be fun to "draw circles" in the sky over Tennessee.

"Wencai, finally check the bomb throwing circuit; Tie Zhong, determine the coordinates again. ”

Hearing the hoarse voice of their commander, Major Zhang Tiezhong and Captain Ma Wencai were not surprised, or they did not hear anything unusual at all.

Unlike when the first "little naughty" was dropped on Kibu in Japan a few years ago, when Japan had lost its ability to resist the air force, the Helleye in charge of the bombing mission at that time had no scruples at all, and the pilot could drive the fighter plane to circle at will, and the bombardier had time to aim at the predetermined area again and again.

And "Lanfen" not only performs missions at night, but also may face deadly interception by the United States. The main thing is that the "radar" aiming of the Lanfen relies entirely on the coordinates provided by the command in advance. In other words, what Oak Ridge looked like below the plane, and what it would become after an air raid, the three pilots had no idea during their mission.

The No. 4 Naughty Bug, which is equipped with a precision guidance device, is not the first "Naughty Buggy" that relies entirely on gliding and flying down, but after being dropped from the designated area of the "Lanfen", it will accurately hit the designated coordinates in the air according to the guidance of the "Lanfen" airborne radar.

In other words, despite the explosive nature and explosive yield of the "Naughty Baby", it is not an ordinary bomb, but a precision-guided nuclear bomb. On its body, it has begun to show the demeanor of medium- and long-range missiles loaded with nuclear warheads that can carry out precision strikes in later generations.

The bombing site of the Lanfen was more than ten kilometers away from the explosion point, and there was no attack from other enemy aircraft, which allowed it to maintain a smooth flight posture and provide sufficient guidance commands for the "little naughty" in the fall.

At this moment, at 04:00 on July 13, 1944, "Turn on all avionics and restore on-board communications!"

The captain, Colonel Li Fansheng, shouted loudly, the cabin was so big, there were only three people in total, and in an extremely closed environment, soft voices could be heard. Such a loud volume is purely due to nervous feelings.

Major Zhang Tiezhong and Captain Ma Wencai did not panic, and turned on the switches of various equipment in an orderly manner. Although their expressions were equally stern, in the almost constant temperature cabin, a little bead of sweat actually appeared on their foreheads.

"Keep course, get closer to the target...... The countdown began, 19, 18, 17 ......" The three pilots seemed to have turned into statues, even their eyes were motionless, only Major Zhang Tiezhong's slightly trilled countdown sound, as the number shrunk, Captain Marven raised his right hand, and pressed on the dark green weapon launch preparation button in the big cave, the fuselage shook slightly, and the weapon compartment under the belly of the aircraft had been opened, just like the monster that devoured the end of the world opened its big mouth full of fangs, showing the world how terrible it was.

However, at an altitude of 15,000 meters, in the silence of midnight, no one can appreciate its hideousness.

The night in the Cumberland Mountains is not silent, with the occasional long wolf howl imbuing it with a pristine atmosphere.

The Americans resettled, relocated and built the Black Oak Ridge Valley three years ago, but they did not change the natural features and biological chains of the area too much, which is a good cover for the existence of the nuclear engineering area.

Lieutenant General Groves, the leader of the "Manhattan Project", mentioned in his report to the president, "Our Air Force has done tests, and if it is not pointed out in advance, it is difficult to detect the Y-12, K-25 and X-10 at an altitude of thousands of meters, let alone the real yàn room institutions, which are mostly located underground!" Therefore, as long as we do a good job of secrecy, I firmly believe that the Allies will not be able to discover the existence of the engineering area by means of aerial reconnaissance."

-- The United States has built three nuclear facilities at Oak Ridge: the facility codenamed "Y-12" is mainly used to separate uranium-235; The facility, codenamed "K-25", separates uranium-235 in a more economical way through a very large-scale facility; The facility, codenamed "X-10", is a graphite atomic reactor.

In fact, what Lieutenant General Groves said is true, if it weren't for Zhong Yi's rebellion, in his previous life, until "Delmar" defected to the Soviet Union, the world gradually understood Oak Ridge, the city that pushed the earth into the "nuclear world".

But for Zhong Yi, no matter how strict the secrecy measures are, it becomes meaningless, not to mention that "Delmar" in this world has devoted himself to the Imperial Military Intelligence Bureau early.

Major Zhang Tiezhong's countdown continued, "7, 6, 5......" Captain Ma Wencai's right thumb moved again, this time, pointing to the bright red and dazzling launch button.

"3, 2, bomb dropping!" Not only Major Zhang Tiezhong, but when the indication coordinates that marked that he had entered the predetermined range turned red, Colonel Li Fansheng also shouted, as if releasing the depression in his heart, and the weapon operator Captain Ma Wencai pressed his thumb hard, and also shouted, shouting still those two words, but half a beat slower than the two in front.

The mechanical arm in the weapon bay shook slightly at the moment when the red button was pressed, and the joints that fixed the giant bomb opened outward, and the No. 4 "Little Naughty" was finally untied from all restraints and fell down freely.

"Close the weapons hatch and start heading back." The release of the love did not make several of the Empire's most elite pilots forget their jobs. Major Zhang Tiezhong found the reminder command again, but after the shout just now, and the "little naughty" Shun lì drop, his voice had recovered to his usual low level.

Piloted by Colonel Levan Thanh, the giant iron bird-like "Lan Fen" first changed from a level flight to a 60-degree dive, and then made a 160-degree turn, during which it took only 12 seconds to restore a smooth parallel in the opposite direction.

After another three seconds, Major Zhang Tiezhong had already found the little mischievous in the radar screen, "The radar is locked, keep the level flying...... The coordinates were calibrated, and an explosion occurred twenty-two seconds later. ”

Captain Marvencai in the back seat clenched his fists and let out a "yes" sound. In fact, you don't need Zhang Tiezhong to read it out, you can see these numbers in the radar display in front of the three pilots, but only when Zhang Tiezhong, who is the navigator and radar operator, reads it out, will he finally say that he is confirmed, which makes people feel much more at ease.

Li Fansheng did not move, the follow-up radar guidance requires the aircraft to remain stable and parallel, at this time, if the fighter makes a violent action, it will guide the bomb to lose its guidance and explode without a target, which will make the effect of the explosion much less, and even many unknown problems will appear.

"It's not a trivial matter to get lost in the 'little naughty'!" Li Fansheng's eyes were fixed on the various meters in front of him, but the movements at the corners of his mouth had already revealed the joy in his heart. At this stage, there is no one left to stop the little mischievous explosion!

Zhang Tiezhong started the countdown again, and a row of small light spots marked the trajectory of the "little naughty" flight on the radar screen, according to the plan, the No. 4 "naughty baby" will explode at 500 meters above the most central position of Oak Ridge, where the command also calculated the most likely Y-12, that is, the workshop for separating uranium-235 according to the photos taken by the Air Force reconnaissance plane risking death.

"5, 4......" This time, Ma Wencai, who had completed his task, also joined the countdown, and after the two of them counted out the last "2", they shouted, "Explosion...... Hey, is it a dud? ”

But before they could finish speaking, a dazzling white light lit up the entire night sky, brighter than the sun and whiter than the aurora.

Captain Ma Wencai was also able to pass through the infrared camera installed in the tail of the plane and saw a huge circular fireball rising into the air, expanding dramatically. And then...... Then there was a huge shock wave mixed with the sound of explosions, which made the "Blue Fen" tremble violently.

All three of them knew that this was the reflected wave after a nuclear explosion, and during the training, there were Air Force experts who specially explained this common sense.

Marven's eyes widened, "Mushroom cloud...... Wow, how long does it take for many people to eat such a big mushroom? ”

"Damn, no one can understand the world of foodies!" Li Fansheng rolled his eyes, turned on the communicator, and began to call the command headquarters. You can see these numbers, but only when Zhang Tiezhong, who is a navigator and radar operator, reads them out, will he finally say that he is generally confirmed, which makes people feel much more at ease.

Li Fansheng did not move, the follow-up radar guidance requires the aircraft to remain stable and parallel, at this time, if the fighter makes a violent action, it will guide the bomb to lose its guidance and explode without a target, which will make the effect of the explosion much less, and even many unknown problems will appear.

"It's not a trivial matter to get lost in the 'little naughty'!" Li Fansheng's eyes were fixed on the various meters in front of him, but the movements at the corners of his mouth had already revealed the joy in his heart. At this stage, there is no one left to stop the little mischievous explosion!

"Damn, no one can understand the world of foodies!" Li Fansheng rolled his eyes, turned on the communicator, and began to call the command headquarters.
