"Especially, when our navy needs to land across the sea, this kind of naval gun will strike the enemy, which is quite powerful." Xie Huimin continued: "After all, the power of a 203mm naval gun is far more powerful than that of our current one."
Some 130mm naval guns.”
Landing across the sea! The statement proposed by Xie Huimin is the most lethal.
The navy is the most expensive, and the country's military expenditure is tight, so there is not much money that can be invested in the navy. In the several amphibious landings after the founding of the People's Republic of China, even civilian ships were used, and the army's artillery was used.
No countertops are allowed.
Now, although the Navy has some large-class destroyers, it only uses 130mm naval guns. This kind of naval gun was also the technology of the Soviet Union in the 1950s and is now out of date. Therefore, for the Navy,
For example, developing a special large-caliber long-range naval gun to attack strong firepower points on land is the most suitable solution.
Before Xie Huimin came, he did a lot of homework. Now, after hearing Xie Huimin's introduction, Mr. Pan frowned and said, "Old Xie, what you said is very good, but the 203mm ship cannon
, our destroyer's small body can't bear it, it's at least a 10,000-ton warship."
In the naval naval gun field, 203mm naval guns are also quite common, even in the form of two- or three-way units. However, this kind of naval gun is used on battleships.
In the past, the era of heavy ship cannons, cannons with a caliber of 400 mm were common, and 200 mm was a second-class citizen. What about now?
The times have changed now. The era of battleships has passed. The largest warships in the navy, except aircraft carriers, destroyers, and cruisers, are not many. Look at the country, there are only large-scale brigades with a displacement of more than 3,000 tons, even if they are currently planning.
The level 052 in the research was only 4,000 tons of water displacement. If you install a 203mm naval gun, don’t you think it’s a small body and a big head?
(To briefly introduce, the brigade level and brigade level that are easily picked by military fans are actually codenames from abroad. In the words of domestic military workers, they do not call it that way. They never call it from the Soviets.
The 24 helicopter is a female deer, and the MiG 25 is a fox bat. These are all named in the West. It is said that the first time that Western intelligence discovered a new destroyer, Lushun Dalian, connected the two words together and created a hiking-level class.
Later, it was natural. Of course, there was also some saying that I found two names to name them from the computer. However, in short, when I talked to the domestic engineers, they always felt that they were not good at traveling to the top and Shanghai level.)
"Old Pan, have you heard of the American MK71 naval gun?" Xie Huimin said: "We are aiming at this naval gun and strive to achieve the same performance level. The "Hall" of this naval gun was tested at sea
The displacement of the USS destroyer is only 4,000 tons, so it is absolutely fine to use it on our second-generation destroyer. This thing is the best choice for ground support."
Back then, the triple 203mm naval gun used by the Americans had already lagged behind, and their conventional 127mm naval gun felt a little overwhelmed with the ground fire support, so the Americans began to tinker with it, and in 1974, they began to tinker with it.
Various sea shooting tests were conducted on the Sherman class Hall.
If you want to be installed on a warship with a displacement of 4,000 tons, you must reduce weight. This k71 naval gun uses a wide range of automation and lightweight design to control the volume and weight of the artillery. For example, the turret
Some of the total weight is only 80 tons, which is equivalent to the domestic double 130mm naval gun.
They made this kind of gun, of course, to be able to use a large number of standard M25 203mm grenades in stock during World War II. The maximum range when firing this ordinary grenade was 24 kilometers. At the same time, they also specially developed a supporting ammunition supply device.
Now, holding a design drawing of MK71, a common cross-sectional picture in military magazines, Xie Huimin began to introduce it. After all, this is the first time that the second machine factory has been engaged in a large-caliber naval gun project, and he really hopes to win
In this contract, the Second Machine Factory built artillery. Since it was built artillery, it would be necessary to build the most powerful artillery.
"First of all, we will increase the length of the gun barrel and reduce the volume of the medicine room. This will optimize the ballistic performance of the shells, and at the same time reduce the back seat energy of the artillery firing, reduce the weight of the return aircraft, and in the gun stand
For parts, such as rotation and gear mechanisms, we can also use high-strength aluminum alloy and other materials to reduce the weight of the turret to within 80 tons. The rear seat of the artillery shooting will also allow the 4,000-ton destroyer to withstand it.
As for performance, we plan to achieve a range of 80 kilometers when using rocket-boosted grenades!”
I don’t believe these data and they are not moved!
Now, the domestic 203mm land cannon can reach fifty kilometers. This is definitely not the end, it is just the beginning! After all, we have already achieved fifty kilometers based on the 155mm cannon.
The same solution will be improved to allow the 203mm gun to launch a special rocket to boost the missile to fly for 80 kilometers, which should not be a big problem.
Eighty kilometers, as long as you are in the middle of the strait, you can reach the other side, which is a perfect match.
"Old Xie, we are quite interested in the cannon you mentioned, but I also have a request." Old Pan looked at Xie Huimin and said, "If you develop it, we will recommend it to the Navy, but if you do it,
I want to ask for research and development funds from us, so, haha, there is no way.”
Xie Huimin's face looked a little ugly. Why is this old Pan so ugly?
Besides, we shouldn’t you pay for the Navy’s research and development?
"You also know that the navy is the most short of money." Pan said: "Now, in order to import a large amount of equipment from abroad for the second generation of destroyers, the navy has no money, so you want to get from me
If we dig funds, it is absolutely impossible. All our funds are spent on the research and development of second-generation destroyers. This is our first ship in China!”
The 052-class destroyer that was to be built in the plan is to be the first ship in China. They have to spend all their funds on it, and it is absolutely impossible to allocate funds to this 203mm gun.
"Can I say something?" At this moment, Qin Zhenhua spoke: "You lack funds, why don't you sell the warships? As long as you can sell them, you can make money!"
