"Especially, when our navy needs to land across the sea, this kind of naval artillery strikes the enemy, which is quite powerful." Xie Huimin continued: "After all, the power of the 203 mm naval gun far exceeds our existing 130 mm naval gun. ”

Landing across the sea! Xie Huimin's statement is the most lethal.

The navy is the most money-burning, and the country's military spending is tight, so there is not much money that can be invested in the navy, and in several amphibious landings after the founding of the People's Republic of China, even civilian ships are used to carry the army's artillery, which is simply not on the table.

Now, although the Navy already has some brigade-class destroyers, but only 130 mm naval guns are used, which are also the technology of the Soviet Union in the fifties, and now they have long been outdated, so for the Navy, it is the most suitable plan to develop a special large-caliber long-range naval gun to attack solid firepower points on land.

Xie Huimin had done a lot of homework before he came, and now, after hearing Xie Huimin's introduction, Pan Lao frowned and said: "Old Xie, what you said is very good, but the 203 mm naval guns, the small body of our destroyer, I'm afraid it can't bear it, let alone a 10,000-ton battleship." ”

In the field of naval artillery of the Navy, 203 mm naval guns are relatively common, even in the form of two or three installations, but this kind of naval guns are used on battleships.

In the era of heavy ship cannons in the past, cannons with a caliber of four hundred mm were common, and two hundred mm was a second-class citizen, and now?

Now the times have changed, the era of battleships has passed, the largest warships in the Navy, in addition to aircraft carriers, are destroyers, cruisers are not many, and then look at the country, there are only brigade classes with a displacement of more than 3,000 tons, even if it is the 052 class that is currently being planned and studied, the displacement is only more than 4,000 tons, and the installation of a 203 mm naval gun, don't you think it's a small body and a big head?

(To briefly introduce it, the brigade level and the Shanghai level, which are easily brought by military fans, are actually foreign code names, and they are not called so in the mouths of domestic military workers.) It is said that when Western intelligence first discovered the new destroyer, Lushun Dalian, the two words were connected, and a brigade was made, and then it was logical to come down, of course, there are also some sayings that they randomly found two names from the computer, but in short, talking to engineers in China, a brigade level, a brigade level, always feel nondescript. ）

"Old Pan, have you heard of the MK71 naval guns of the Americans?" Xie Huimin said: "We are aiming at this naval gun, and strive to achieve the same level of performance, this kind of naval gun in the sea test of the "Hall" destroyer displacement is only 4,000 tons, so it is absolutely no problem to use it on our second-generation destroyer." This thing, ground support, that's the best option. ”

At that time, the triple 203-mm naval guns used by the Americans were already backward, and their conventional 127-mm naval guns felt a little inadequate for ground fire support, so the Americans began to tinker, and in 1974 began to conduct various sea shooting tests on the "Sherman" class "Hall".

If you want to install it on a warship with a displacement of 4,000 tons, you have to reduce the weight, and this K71 naval gun has been relatively successful in controlling the volume and weight of the gun by adopting a wide range of automation and lightweight design. For example, the total weight of the turret part is only 80 tons, which is comparable to the domestic twin 130-mm naval guns.

They engaged in this artillery, of course, in order to be able to use a large number of M25 203mm grenades stockpiled during World War II. The maximum range of this ordinary grenade is 24 kilometers, and at the same time, a supporting bomb supply device has been specially developed.

Now, holding a design drawing of MK71, the kind of common cross-sectional drawings in military magazines, Xie Huimin began to introduce, after all, this is the first time that the Second Machine Factory has been involved in a large-caliber naval gun project, and he very much hopes to win this contract.

"First of all, we will lengthen the length of the barrel and reduce the volume of the chamber, so that the ballistic performance of the shell can be more optimized, and at the same time, the recoil energy of the gun launch will be reduced, and the weight of the recoiler will be reduced. We plan to have a range of 80 kilometers when using rocket-propelled grenades! ”

These data, I don't believe that they are not impressed!

Now, the domestic 203-mm land cannon is already capable of hitting fifty kilometers, and this is definitely not the end, this is just the beginning! After all, on the basis of the 155-mm gun, the own side has already achieved 50 kilometers, and the same scheme should be improved, so that the 203-mm gun can launch a special rocket-booster projectile and fly 80 kilometers, there should be no big problem.

Eighty kilometers, as long as you are in the middle line of the strait, you can hit the other side, which is a perfect match.

"Lao Xie, we are more interested in this cannon you are talking about, but I also have a request." Pan Lao looked at Xie Huimin and said: "If you develop it, we will recommend it to the navy, but if you want to ask for research and development funds from us, this, hehe, no way." ”

Xie Huimin's face was a little ugly, why did this old Pan speak so ugly?

Besides, if we give research and development to the Navy, shouldn't you pay for it?

"You know, the Navy is the most money-hungry." Pan Lao said: "Now, the navy has to import a lot of equipment from abroad for the second-generation destroyer, and there is no money, so if you want to dig funds from me, it is absolutely impossible, and all our funds are used for the research and development of second-generation destroyers, which is our first ship in China!" ”

The 052-class destroyer to be built in the plan is to be the first ship in China, and they have to spend all their funds on it, and it is absolutely impossible to allocate funds for this 203-mm gun.

"Can I say a word?" At this moment, Qin Zhenhua spoke: "You lack funds, why don't you sell the warship?" As long as you can sell, you can make money! ”
