Chapter 277 Smoothbore Cannon

Chapter 277 Smoothbore Cannon

Of course, among the current military products of the Zhujiang Plant, there are still several items of equipment and processes that are listed by the headquarters as non-transmissible equipment and processes like the liquid phase sintering process.

For example, the self-tightening equipment and technology of long tube parts of special pressure vessels is a typical example.

At first, Zhujiang Factory mainly developed equipment and processes for the production of various fire-fighting pipelines, hydraulic pipelines and a series of special pipeline equipment on ships.

It was later used in the manufacture of the DPZ-076 76mm naval gun barrel.

After all, it is a high-level dual-purpose gun with a rate of fire of 120 rounds per minute. If the quality of the barrel is not good enough, it can be said that everything will stop.

在此基础上株江厂又连续开发了DPZ—100型100mm口径舰炮和DPZ—130型130mm舰炮以及DPZ—030型30mm机关炮。

Especially the DPZ-030 30mm machine gun, which belongs to a multifunctional small-caliber naval gun developed by Zhujiang Factory for the future!
Yes, you read that right, the DPZ-030 30mm machine gun is not a special artillery developed for the army, but is intended for the navy.

Its main purpose is air defense, as well as attacking small targets at sea.

因此DPZ—030型30mm机关炮最高射速达到600发\分钟,远高于海军目前装备的76式双联装37mm舰炮每门260发\分钟以及改进型的每门376发\分钟的射速。

It is a relatively good small-caliber artillery.

However, after conducting a series of relevant assessments, the Navy believes that there are many large overlaps in performance between the DPZ-030 30mm cannon and the Navy's current Type 76 dual-mounted 37mm naval gun.

Although the rate of fire is superior, it is not obvious in front of the improved version of the Type 76 dual-mounted 37mm naval gun. After all, the Type 76 is a dual-mounted, and the rate of fire needs to be multiplied by 2. The DPZ-030 30mm cannon is only a single door cannon.

In addition, the navy felt that the DPZ-030 30mm machine gun had a low overall redundancy of a single tube, and it was not as reliable as a dual installation, so it rejected the DPZ-030 30mm machine gun in the initial evaluation.

Although the Navy rejected the DPZ-030 30mm machine gun, it did not really kill it with a stick, but allowed it to be exported in the name of "special industrial products".

At the same time, Wen Dawei made adjustments to the business strategy of the DPZ-030 30mm machine gun, reducing the rate of fire and increasing its power, and at the same time equipped it with a 30mm long-rod fin stabilized sabot-piercing projectile.

Make it a sharp weapon with precise strikes on land targets. Then, when the Marine Corps is in urgent need of infantry fighting vehicles, a turret module is configured on the basis of the DPZ-030 30mm cannon and placed on the Type 63 armored vehicle. Thus opened the prelude to sales to ground forces.

The reason why Wen Dawei is so confident in reselling the ground troops after the navy's rejection is that, in addition to figuring out the needs of the ground troops in this regard, the most important thing is that he is very confident in the quality of his own products.

You must know that the DPZ-030 30mm machine gun adopts a relatively advanced hydraulic self-tightening process in the world today.

And this process is usually used to produce large-caliber tank guns, howitzers and naval guns in developed countries such as Germany and France, because the structure of the whole set of equipment is very complicated and the cost is extremely high. Only large-caliber heavy weapons can offset the super high the cost of.

But in Zhujiang factory, this kind of process is used to produce small and medium caliber artillery below 100mm. The main reason is that the inner bore mold of the more efficient mechanical self-tightening equipment in Zhujiang factory cannot be used in small and medium caliber artillery. The self-compacting process can only be accomplished with more traditional liquid injection.

More advanced and efficient mechanical self-tightening equipment is used to produce large-caliber naval guns over 100mm.

Of course, whether it is a hydraulic self-tightening process or a mechanical self-tightening process, today's companies are working at full capacity to produce spare tank gun barrels for the Bosnian armored forces.

Among them, the hydraulic self-tensioning process is used in the production and manufacture of 90mm smoothbore guns, which are mainly equipped with M48 series main battle tanks in the Bosnian Armored Forces.

The mechanical self-tightening process is used for the production and manufacture of 105mm smoothbore guns, which are mainly equipped with the medium-sized M60 series main battle tanks of the Bosnian armored forces.

The reason for this is that there is no way, who let Bosnia’s regime change in the late 70s affected its relationship with Europe and the United States, resulting in the lack of maintenance and upgrade of many advanced equipment imported from Europe and the United States in the 6s and 7s.

The F-14 fighter jet counts as one, and the M48 and M60 main battle tanks also count as one, and it is even more important.

After all, the Iran-Iraq battlefield is dominated by large ground corps operations, and tanks, as the main force of the army, play a pivotal role, even decisive in some respects.

However, due to the lack of sufficient spare parts, ammunition and maintenance, the M48 and M60 in Bosnia's hands only appeared a few times at the beginning of the development, and they rarely galloped on the battlefield after that.

Other aspects are not bad, the parts of engine, gearbox and suspension system can still be bought from European countries through certain channels.

However, the dedicated spare barrels and armor-piercing projectiles are useless, so Bosnia can only keep the M48 and M60 in the rear for temporary storage.

As for the armored forces, the foreign exchange earned from oil exports was used to purchase T-55, T-62, and T-69 tanks with sufficient maintenance and ammunition supplies from the Soviet Union and other countries.

It wasn't until Zhujiang Factory developed the first phase of the SJ-857 series of experimental ammunition and demonstrated its excellent performance in tank-specific smoothbore guns that the Bosnian side made up its mind to use the two American-made tanks hoarded in the rear.

Of course, relevant tests and evaluations are indispensable.

It's just that compared to the domestic rigor, the Bosnian side is much simpler. After all, it is a wartime state, and some unnecessary red tape can be cut as soon as it can be cut.

Therefore, the relevant results are also faster than domestic ones.

For example, the first-phase test bombs of the SJ-90 series with two calibers of 105mm and 857mm were sent to Bosnia at the end of last year. In early March this year, a large order for two calibers of long-rod fin-stabilized sabot-piercing projectiles was signed.

Along with these ammunition, the barrels of two 90mm smoothbore guns and two 105mm smoothbore guns were shipped in the name of seamless steel pipes.

After half a month of testing, the Bosnian side was very satisfied with the performance of the two smoothbore guns here. Just three days before these heads came to the Zhujiang factory, Wen Dawei had just reached an agreement with the Bosnian Commercial Representative Office in Hong Kong Island, agreeing to send The Bosnian State Trading Company exported 64 90mm smoothbore gun barrels and 36 105mm smoothbore gun barrels.

The total value is $480 million.

Delivery is expected by October.

So this time Wen Dawei came to Zhujiang Special Steel and Zhujiang Heavy Industry, in addition to the daily coordination, there was also the meaning of implementing production, but he didn't expect that the head of the Marine Corps would be so coincidental, bringing a group of heads over.

Although the heads of several troops did not understand the details of the high-density tungsten alloy long-rod bullet core because of the strict order of the headquarters, they left the powder metallurgy factory helplessly, somewhat regretful.

But it also shows from another aspect that the Zhujiang factory does have extraordinary strength in this area, otherwise why would the headquarters classify other people's craftsmanship as classified for protection?
And when they heard that the smoothbore guns produced by the Zhujiang factory had been exported to Bosnia, they were even more surprised and sighed.

Because the poor production capacity of the Zhujiang factory has been fully occupied by the export list, even if the troops want to, they have to be in the back row...
