The so-called rod-type warhead means that the shrapnel produced by its explosion is not pieces of fragments, but metal rods. These metal rods are pre-surrounded around the shell. After the warhead explodes, the metal rods will fly at high speed.
towards the target, causing a cutting effect on it like a blade. For many aircraft models with strong fuselage, conventional shrapnel has a poor killing effect, and many aircraft shells are even swayed even though they have been beaten into sieves.
It flew back, but when the rod-type shrapnel hit the aircraft, it did not make small holes, but cut a series of holes, which was much more destructive to the fuselage and could easily cause the aircraft structure to disintegrate. The warhead charge
The smaller the quantity, the greater the advantage of this new warhead's killing efficiency compared to conventional warheads. Therefore, the smallest caliber 57mm proximity fuze anti-aircraft shells and this new warhead can be said to complement each other.
When this new type of warhead was first invented, it was questioned that its shrapnel density was too small (the number of preset metal rods in the rod-type warhead was less than one-tenth of the number of shrapnel in conventional warheads), but Hu Weidong insisted on using it
Used in actual combat, the results proved that even against r that lacked armor protection, the fuselage was not strong enough.
Even if the i-type aircraft is used for large-caliber anti-aircraft shells such as 120mm, after switching to a rod-type warhead, the killing efficiency is more advantageous than traditional anti-aircraft shells, and if it is used for relatively small-caliber anti-aircraft shells
She cannonballs, or against the more solid machines of other powers.
model, the effect will naturally be better. In fact, Hu Weidong made this weapon available in advance. The imaginary enemy was not the Japanese aircraft, but the sturdy models of the two giants of the United States and the Soviet Union. Historically, the "aircraft" were famous for their ruggedness during World War II.
"Cement" Il-2 attack aircraft and the American B17 and many other sturdy and durable aircraft
Once a strategic bomber encounters an anti-aircraft shell using a rod-type warhead, the probability of being shot down will increase at least several times, and even if it is injured, it can still escape with great luck. The structural damage caused by rod-type shrapnel can be repaired.
It is also much more troublesome than the small holes made by ordinary shrapnel.
Compared with the improvement of long-range air defense capabilities, the two modified light cruisers also have powerful close-in defense capabilities. After the installation of four twin-mounted 37mm anti-aircraft guns and seven-barreled 25mm "Skynet" close-in defense cannons,
. Its powerful and intensive close firepower is enough to deal with any
He Yiguo's dive bomber group poses a huge threat. Of course, if there are too many enemy planes, these 8 close-in defense artillery systems alone will not be able to stop them. However, no matter how the Omaha class is improved, it is only a 7,000-ton light aircraft.
You can't force it to have the air defense capability of a large warship?
Compared with larger light cruisers, Roosevelt didn't care much about smaller ships, because the Yellow Water Navy could not threaten the United States. Therefore, this naturally became the focus of Zhongfu International's introduction. And the United States'
Over the past year, many shipyards have been forced to use assembly line shipbuilding by Zhongfu International in the field of civilian ships.
The French were defeated, and only those building ships for the U.S. Navy could still rely on military orders to support themselves. Now that Zhongfu International suddenly received a large order, they naturally rushed to grab the head immediately, and for the capitalists
In other words, profit is more important than anything else, and all the previous grudges are nothing but clouds!
And the assembly line shipbuilding method is just one method after all. Zhongfu International can use it, and these shipyards can also use it. In the past, because the market was quickly seized, there was a large backlog of products, which in turn made the cash flow of these companies extremely tight. At this time, Zhongfu International
Fu International also deliberately lowered the selling price of the ships it built, making this
Some companies have been slow to make progress because their profit margins are too low, but this high-priced transfer involving a large number of technical equipment is enough to restore their competitiveness. After that, Zhongfu International’s advantages will no longer exist, and it will no longer want to maintain “the scenery here is unique.”
"The current situation is difficult, not to mention that Zhongfu International is a foreign company after all, and the U.S. government
fu will also be partial to the local ones to some extent, which is undoubtedly more detrimental to Zhongfu International. Fortunately, Mao Zemin realized this in time, and before that, he decisively eliminated all containers and container ships other than patented containers and container ships.
Most of the shipbuilding business was also transferred, which not only avoided losses but also recovered a lot of funds.

As soon as fu supervision was loosened, Mao Zemin's diplomatic and business talents were given the opportunity to be fully utilized. After some efforts, the U.S. Navy actually agreed to sell the world-advanced Porter-class destroyer and transfer a full set of production technology. This could
Hu Weidong, who was thousands of miles away, was so happy that he praised Mao Zemin for doing a great job. You must know that Qingdao Shipyard is now basically
It has the equipment and conditions to produce 2,000-ton warships. As long as the Americans are willing to transfer technology, the shipyard can start mass production soon. Although the destroyer is only a destroyer no matter how powerful it is, there is still an essential difference between being able to produce independently and relying entirely on capture and outsourcing.
The difference. What’s more, the performance of this destroyer is really outstanding. Its basic parameters are as follows:
Full load displacement: 2131 tons;
Main dimensions: total length 116.20 meters, total width 11.28 meters, draft 3.2 meters;
Speed: 37 knots;
Crew: 290 people;
Main gun: 4 twin 127mm high-level dual-purpose guns;
Considering that the Porter-class destroyer has a displacement of just over 2,000 tons, its sea, air and anti-submarine capabilities are enough to satisfy Hu Weidong and several major navy generals, and its speed is also astonishingly fast. However, due to the close-range anti-aircraft guns
Domestic performance was better, and due to the consideration of unified caliber, the 40mm Bofors anti-aircraft cannon originally equipped on the ship was eventually replaced by a 37mm anti-aircraft cannon produced by the Border Arsenal.
, and the 20mm anti-aircraft cannon was replaced by a 25mm anti-aircraft cannon. Since this kind of light warship is generally not subject to priority attacks by large-scale enemy aircraft groups, the "Phalanx" with a huge ammunition consumption was not selected, but
Eight 40mm anti-aircraft guns were replaced with four single 57mm anti-aircraft guns and four twin-mounted 37mm anti-aircraft guns, while the six 20mm anti-aircraft guns were replaced with eight twin-mounted 25mm anti-aircraft guns.
However, this caused the warship's load capacity to increase too much (the installation of many anti-submarine weapons was also a reason, see below for details). After communication between the technical personnel of the two countries, it was finally decided to replace the two parts of the bow and stern of the ship.
The twin-mounted 127mm high-level dual-purpose gun was replaced by a single-mounted 152mm naval gun to strengthen its attack power at sea and on the other side. After all,
A 2,000-ton destroyer is considered a big ship in China, and may be sent out to take on heavy responsibilities when necessary. And it is worth mentioning that a 152mm caliber high-level dual-purpose gun was built in the Central Plains Border Region and mounted on a Porter
After the destroyer, its long-range air defense capability is no less than its original configuration (to be continued.)
