Because there is no such advanced design in the whole world, capable of allowing a fighter of more than twenty tons to take off from the deck of an aircraft carrier.

You must know that in Duan Peng's previous life, the world's first aircraft carrier equipped with a steam catapult only appeared in the fifties, the British Perseus aircraft carrier.

At that time, he was a naval officer, designed and built the first steam catapult, and in 1950, the Mosquito fighter was ejected into the air for the first time.

And now history is about to change, the steam catapult designed by Duan Peng is more advanced than the steam catapult in the early days of another plane.

It can catapult a 30-ton carrier-based aircraft, and this ejection capability can allow aircraft carriers to carry carrier-based early warning aircraft.

Of course, the development of carrier-based early warning aircraft is the next step, and now only the Shanghai Hawk-class carrier-based fighter is needed, and it is easy to eject 22 tons.

According to the size of the Sea Hawk carrier-based fighters, the first aircraft carrier has a full load displacement of 40,000 tons, so that it can carry about 30 aircraft, although the number is far less than the large aircraft carriers of the navies of various countries, but a Sea Hawk carrier-based fighter can withstand ten or more propeller carrier-based fighters, so the combat effectiveness of these 30 is equivalent to 300 ordinary propeller fighters.

Of course, it is not easy for such a heavy carrier-based aircraft to land on the deck of the aircraft carrier, so Duan Peng also designed an advanced steam blocking system, which is equipped with four blocking cables on the tail deck of the aircraft carrier.

This design also surprised the leaders, and they didn't think that there was such a method, after all, it was a fighter plane weighing dozens of tons, and it landed so quickly that it could be stopped by a steel cable, and it was necessary to ensure that the fighter would not be damaged.

Duan Peng also explained to the leaders that this steel cable is not an ordinary steel cable, its bearing capacity is quite high, of course, the cost is relatively expensive, and the carrier-based aircraft also needs to strengthen the structural strength of the fuselage, otherwise according to the structural strength of the land-based fighter, it will be directly pulled apart.

Of course, with a steam catapult, a large amount of fresh water will be required, which will occupy a lot of space on the aircraft carrier.

But this is easy to solve, the aircraft carrier designed by Duan Peng has a preliminary plan with a full load displacement of 40,000 tons, which is definitely a big guy in World War II.

Of course, this is still a lot smaller than the little devil's Shinano, and the largest aircraft carrier in World War II was the little devil's Shinnon.

Originally, this aircraft carrier was a battleship, and construction began in 1940, but after the outbreak of the Pacific War, the aircraft carrier of the little devil suffered a lot of losses, so the Japanese high-level decided to change the No. 3 battleship, which had built half of the battleship, into an aircraft carrier.

The Xinnong aircraft carrier was completed at the end of 1944, and its full load displacement of 71,000 tons can be said to be second only to the Kitty Hawk-class aircraft carrier more than a decade later, and it was the largest in World War II.

Its length reaches two hundred and sixty-six meters and its width is thirty-nine meters.

Because it was designed and built according to the battleship at the beginning, its hangar was relatively small, and it could only carry thirty-two carrier-based aircraft, and this aircraft carrier was also very unlucky, encountering a submarine of the United States Navy, but was torpedoed and sunk.

The aircraft carrier set a record for being sunk in just ten days of service, and it only took four torpedoes to sink it to the bottom of the sea.

This is also because of the Xinnong, which is so poor in construction quality that it is called the tofu slag project.

Now the aircraft carrier designed by Duan Peng is 40,000 tons, so it is larger than most aircraft carriers, especially its flight deck, which can be said to be larger than the Xinnong.

Because in the design of the aircraft carrier deck, an outward floating design was adopted, which was not a design that had been designed during World War II.

Its deck length reached two hundred and sixty-two meters and its width was sixty meters, almost twice the size of the Xinnong.

So if you look down from the air, the first aircraft carrier of the Eighth Route Army, which has a much smaller tonnage, is twice as large as the Xinnong.

This design is also a great surprise to the leaders, such a large deck, how many fighters have to be placed, but because the Seahawk carrier-based fighter is much larger than those propeller fighters, it only carries thirty, and it can also carry more than a dozen helicopters.

In terms of power, this aircraft carrier is even more advanced, because Duan Peng designed four high-power gas turbines to drive the aircraft carrier, each with an output of 25 megawatts, so that the total power reaches 100 megawatts.

Coupled with the advanced large side blade propellers, this aircraft carrier can reach a speed of 30 knots, although it is a little slower than most aircraft carriers, but it is also very good, completely sufficient.

The most important thing is this power system, it only takes a few minutes from starting to full power operation, and it can be started at any time, unlike those steam-powered aircraft carriers, which will take half a day to start, because heavy oil is used, and it is necessary to preheat it first, turn the heavy oil away, and then it is not so easy to boil the boiler, it will take a long time.

Therefore, in wartime, gas turbine power is indeed much stronger than steam power, and it can be dispatched at any time.

And most importantly, if steam catapult is used, the waste heat of the gas turbine can be used to burn the boiler and produce steam, so that the number of ejections will not affect the speed of the aircraft carrier.

The leaders were quite satisfied with the preliminary plan for the Sea Hawk carrier-based fighter and aircraft carrier designed by Duan Peng, after all, this has been ahead of the little devils for more than ten or eight years, and when the time comes, the naval warship formation of the Eighth Route Army will definitely beat the little devils.

This can greatly reduce the pressure on the US Navy, so now the US people must be willing to see the Eighth Route Army have a strong maritime combat force.

And such an advanced aircraft carrier and carrier-based aircraft, the allies must also want it, so when the time comes, they can sell technology to the allies, such an advanced aircraft carrier and carrier-based aircraft, if you don't sell hundreds of millions of dollars, you will be sorry for Duan Peng's payment.

The leaders of the Eighth Route Army were so happy, they all fantasized that the time would come to attack the little devil navy, and they were ashamed of the failure of the Beiyang Naval Division in the First Sino-Japanese Naval Battle that year.

It is true that the Beiyang Navy Division fought very poorly and was defeated in the hands of the little devils, otherwise how could he be bullied by the little devils today.

When the aircraft carrier of the Eighth Route Army was put into service, that is, when the little devil navy was destroyed, the leaders all believed that just one aircraft carrier could beat the little devils, because this aircraft carrier was invincible, and with a complete set of surface and underwater escort formations, it would be difficult to find an opponent in the world.

The project meeting was a complete success, and then Duan Peng will lead the young designers to start designing the Sea Hawk carrier-based fighter.
