Chapter 579: Bomber

The Greenland Air Force Base was brightly lit, and several large bombers were being pulled to the take-off point by tractors.

This is the latest ME264D high-altitude bomber produced in Germany.

This bomber pursues high-altitude flight performance to the extreme, and uses a large amount of chromium-nickel-manganese super-hard aluminum alloy to reduce the weight of the fuselage; it is equipped with four 2,000-horsepower liquid-cooled engines, plus a new four-blade propeller and a new turbocharger, and the ceiling reaches an astonishing 14,000 meters.

At present, no fighter can climb to this altitude to fight. Even at the end of World War II, only the TA-152 fighter could barely reach this altitude; the maximum ceiling of the US P51 is only 12,700 meters.

Even if the ground air defense force's large-caliber anti-aircraft guns with a caliber of more than 100 mm can shoot to this altitude, there is almost no accuracy, and there is nothing to be afraid of.

In other words, the ME264D high-altitude bomber is very safe at this altitude. For this reason, this bomber has even cancelled all self-defense weapons and is not equipped with even a machine gun or a turret.

After the tractor left, the ground crew drove the power truck to help start the engine.

In World War I and even in the early days of World War II, aircraft engines required ground crew to push the propeller hard to start the aircraft. When the propeller obtains enough rotational inertial kinetic energy, the decompression device opens the exhaust valve. After the exhaust valve is closed in the next compression stroke, the fuel injector sprays oil into the cylinder. As the piston continues to compress, the temperature and pressure in the cylinder gradually increase, and the gas will burn to generate thrust, pushing the engine to continue to rotate, and the engine will complete the starting process.

As the power of aircraft engines becomes stronger and stronger, and the number of cylinders increases, manual starting becomes more and more difficult. In particular, cold starting when the oil is condensed is already half dead for ground crew.

For this reason, engineers began to think about new methods that save time and effort. Soon, various methods such as "electric start method", "compressed air start method", "inertia start method" and "gunpowder start method" came into being.

Germany uses the electric start method, which is efficient, convenient, safe and environmentally friendly. However, the energy density of the battery is low and the capacity is small. The battery pack that can drive the aircraft engine is too large and heavy, and it cannot be installed on the aircraft. It can only be used with an external battery trailer, and there are multiple sets of batteries in the trailer in series, which has many restrictions.

Fortunately, the development of technology during the war is changing with each passing day. Before long, the German Air Force will be able to use the "APU auxiliary power unit" to reduce its dependence on ground power supply equipment.

The huge propeller of the four-engine heavy bomber slowly turned, and as puffs of black smoke spurted out, the engine was successfully started.

Daniel checked the various instruments and reported to the tower. "Tower, the Black Hawk Squadron is ready, requesting takeoff."

"Allowed to take off, I wish you a triumphant return!"

Daniel pushed the throttle lever to the maximum, the engine roared, and the propellers on both sides turned faster and faster. The plane began to slide forward along the runway. When the pointer on the speedometer pointed to the takeoff speed value, Daniel pulled the control lever hard, and the heavy body of the bomber slowly left the ground and began to climb up.

One hundred meters, two hundred meters, five hundred meters, one thousand meters... The altimeter has shown 10,000 meters. In this era, this is already the ceiling of many high-altitude fighters.

The co-pilot said excitedly. "Haha, we will be the first bomber to bomb the US mainland, and we will definitely scare those ignorant Americans."

"This is a long voyage." At their speed of 450 kilometers per hour, it will take at least ten hours to reach the US mainland, and they will not fly directly to the US mainland, but will go to Ottawa, the capital of Canada, first. The interesting thing is that this trip to Ottawa is not to drop bombs, but purely to scare them.

In order to ensure that they can fly a sufficient range, each of their planes only carries 3 tons of special bombs, and the rest of the space is filled with fuel. And there are three pilots on each bomber, taking turns to drive.

More than three hours later, at a radar station on the Canadian border, the radar soldier panicked and called the sleepy officer. "Sir, there are enemy planes on the radar!"

"!!" The officer suddenly lost all sleepiness and grabbed the phone next to him. "Contact the anti-aircraft artillery position quickly, what is the altitude?"

The radar soldier said in disbelief. "The altitude is over 12,000 meters."

"What?!" The officer looked at him in astonishment. "Did you see that right?!"

"Unless this broken machine breaks down again!" It is indeed a broken machine. The radars deployed by Canada on the border are second-hand goods discarded by the United States. The detection range is only about 50 kilometers, and it often breaks down.

"Oh my God." The commander of the air defense position who received the notification from the radar station sighed helplessly.

12,000 meters, they don't have anti-aircraft guns that can reach this altitude. "Record the opponent's course and report to Ottawa."

At this time, in the Prime Minister's Office in Ottawa, the Canadian Prime Minister (William Lyon Mackenzie King) was cursing and writing a resignation letter. After cursing Germany, he cursed the United States, and after cursing the United States, he cursed himself. "I am such a fool, I might as well resign last time!" As mentioned earlier, Germany's declaration of war on Canada caused a large amount of European foreign exchange in the Canadian treasury to become waste paper, and the domestic economy suffered a huge impact.

Although he was almost forced to resign, he still gritted his teeth and persisted.

But they never expected that in this Greenland operation, the fleet they sent out was all sunk, and thousands of sailors were killed.

Under the criticism of the opposition party and the protests of the people, he really didn't have the face to continue sitting in this position, so he could only choose to resign. "I really deserve it! It's all the fault of that stupid Roosevelt!"

Just as he sighed and complained about the world, the secretary with a panicked face hurried in. "Mr. Prime Minister, Mr. Prime Minister, news came from the border that the German bomber group has entered our airspace."

"What?" The Prime Minister was shocked. The Germans are going to retaliate against them for Canada's participation in this Greenland operation?

But they are the ones who suffer, okay? What revenge are the Germans going for? "Where did they bomb?"

The secretary shook his head. "They didn't bomb, they are still deep in the hinterland."

"..."The Prime Minister's heart was faintly uneasy. Canada is vast and sparsely populated (an area of ​​9.97 million square kilometers, with a population of about 70,000 at this time), and there are only a few large cities worthy of German bombing.

Are the Germans planning to bomb Ottawa?

"Oh my God!" The Prime Minister was shocked by his own guess and quickly ordered. "Quick, contact the city defense headquarters and impose a blackout in the entire city."
