Chinese Navy (PLAN) News & Discussions

That is extremely good to hear!
Will 096 get inducted with JL-3 off the bat, or is it expected to start operations with JL-2 first?

Not particularly surprising, given recent activity at the Bohai Shipyard. Also, the 096 will definitely start out with the JL-3 ... it takes longer for the dev of the former than the latter.

Can you post the essay? Do we know what stage of construction they're in?



Not sure, but the rocket motor for the JL-3 first stage was supposedly tested in 2017, so the project is definitely in full swing. Henri K. predicts an entry-to-service date of 2026, roughly in line with the 09VI program.

I’m not sure though. The 096’s entry date should be around 2023, in line with the 095. So I’m not sure why the JL-3 will have to wait so long ...

You're basing these dates off of what?

Going by the latest "eight-part essay" productions of both 095 SSN and 096 SSBN are in full swing.

Quantum leap in ALL that matter.

Here is the full article. If somebody could translate, it would be highly appreciated.

【贯彻落实新时代中船重工高质量发展战略纲要】七一九所：这一场变革不容易

“这一整节车厢快被我们的人包了”。


这是今年2月28日，中船重工七一九所一位科研人员在微信工作群里的留言。那一天，飞驰的G1290动车载着七一九所人，赶赴离家千里之外的建造厂，开始厂所融合设计的新征程。


就在半年前，由七一九所冷文军总师带队，这支60余名精兵强将组成的设计队伍，雄赳赳开赴配建现场，打了一场艰难而又漂亮的硬仗：平均每天发放90份包含大量结构、设备或管路的三维数据包。


60多人，90份三维数据包！这相当于每人平均每天要画1.5张图纸，而在过去，同样一张图纸要耗时1～2周。况且，这些经过精准计算、精细设计的数据包，其设计内涵远超过以往数张施工设计蓝图。


那一场硬仗打了80多天。60多人通过“5+2”、“白+黑”奋战，完成了63000余道审签工序，向工厂发放7000余份经过精确计算、精细设计、精准定位的三维数据包，顺利完成了某产品的设计数据发放任务。这是一个让人惊叹的记录，比以往型号的施工设计供图整整快了一年！


一年啊，对等不起的工程任务来说，是何其珍贵的12个月！


当七一九所科研人员点击最后一份数据包“归档”按钮时，在场的年轻人无不高声欢呼，不少人眼里饱含泪花。那一瞬间，数年奋斗历程中难忘的点点滴滴都在眼前浮现：有的科研人员奋战至午夜双目干涩仍不肯下机；有科研人员痛失至亲却回家短短三天就又归队参战；还有刘义成副总师，年过五旬还亲手翻译3000余页资料；冷文军总师无数次如琢如磨研究问题至深夜……


一切努力，都是为了一场叫“全三维设计”的设计模式变革；赢回的时间，离不开那场叫“全三维设计”的设计模式变革。


“全三维设计”有很多种含义。一是全过程，从方案论证阶段开始进行三维设计，不再是以往型号二维设计为主、三维设计进行空间校核的模式，可开展各阶段的总体平衡。二是全要素，不仅关注总布置设计，还要解决集成优化、声学、维修性、人因工程等诸多要素的集成设计与验证问题。三是全寿期，不仅立足于总体设计，还要解决可生产性检查、生产设计融合、工装对接、虚拟建造、数据交换等上下游问题。


多年来，七一九所采用二维图样为主、三维校核为辅、串行设计与发放的设计方式。这种设计方式存在显性化、精细化不够、总体综合平衡深度不足、并行设计难以开展等问题，难以支撑高精尖装备的研制。七一九所人意识到，要提高设计质量和效率，满足研制新时代一流装备的需要，唯有从研制方式上入手排除万难进行变革，才能不辱使命，完成党和国家的重托。


变革从来就不会一帆风顺。七一九所推行全三维设计面临种种难题。一是没有体系，需要全面开展三维数字化定义体系和管理体系研究、设计方法和标准研究、设计环境和数据管理系统研究等。二是没有先例，行业惯例要打破，研制模型要重新建立，思想认识要逐步统一，尤其是习惯成自然的二维图样管理制度，碰到三维设计条件下如何融合工厂工艺设计、如何实现数据全息传递、如何数字化检验等，都变成了令人望而生畏的问题。三是没有时间，型号研制进度紧迫，他们相当于一边“造飞机”一边还要“开飞机”赶进度，大量繁杂的研究工作已使七一九所科研人员高负荷运转，如今还要领先一步建立全三维数字化设计体系，不容人有半点喘息机会……


“这是一条正确的必由之路，为了推动我国舰船事业高质量发展，再难我们也要做。”七一九所邱志强副所长志坚如磐。


“我们要在短时间走完先进国家几十年走过的路。”翁震平所长在一次大会战动员会上深情地说。他还亲自用科学家的严谨，带着行政线、技术线对这一场革命进行了高度概括，凝练成“2+2+1”理念。


对，他们为之持之以恒奋斗的就是“2+2+1”！这凝结了七一九所几十年工程型号研制智慧，也昭示了未来的高质量发展理念。第一个2是基础，即基于三维数字样船的定量计算仿真、基于实船背景严格的集成试验验证。第二个2是方法，即采用功能性能与隐身、六性、可生产性等多质量特性相融合的设计方法，采用全三维设计、多专业并行、厂所融合的设计方法。第三个1是目标，实现深入到系统、设备、零部件的总体设计量化精准的目标。


按照“2+2+1”理念指导，七一九所举全之力，体系化地开展了大量技术研究和开发工作，贯通了全三维设计途径。利用这些研究成果全面开展的型号精细化设计，“步步为营”，环环相扣，经过规划设计、完整性设计、综合平衡、多特性校核、可生产性平衡、试验验证、数字样机评审等迭代设计活动，直到达到用户提出的“精品工程”要求。


结果令人欣慰！这一场全所未有的设计模式变革，推动了跨专业、跨部门跨厂所的并行协同设计，最终构建了面向建造、覆盖全船各功能系统的数字样船：各系统和部件采用三维数字化模型进行装配、检查和协调，实现了大型船舶100%的三维建模和100%精确定位的多专业并行协同产品数字化定义。七一九所在收获“国防科技工业信息化推进工作优秀单位”等荣誉称号的同时，也得到了用户的高度赞誉，称其为船舶行业的“革命性和引领性突破”。集团公司领导也充分肯定了这一场变革带来的成效——“第一次在船舶行业看到了全三维数字样机”。


如今，七一九所建设了多个虚拟现实厅，有全船级的演示大厅，也有工作组级的协调小厅。在这些虚拟现实厅里，你可以看到这样一副生动妙曼的场景：设计人员正戴着导航头盔，在沉浸式虚拟现实场景中“漫游”；通过手中的手柄，他们可以多人同时“抵达”船内任何地方，对照模拟实物讨论设计方案，检查设计结果；他们可以与受邀来的建造厂技术人员、军方代表一道，共同评估可生产性、体验操作……


这样一幅高度融合的图像里，写满了七一九所人矢志不渝打造高质量产品的担当精神、创新勇气和实践智慧。

Pardon, but why do you post an Army Aviation Z-19 in a PLAN news thread???

its a picture of recent drill to warn taiwan authority near jinmen of taiwan province

 

[cirr]

It looks though the PLAN is developing a new class of heavy surface combatant.

20000-ton plus cruiser? 40000-ton plus battleship?

With all sorts of missiles and guns and directed-energy weapons...

Class? As in, not an improved 055 but something different? And bigger still?

I think that we might get that Arsenal ship after all! Another option would be a command cruiser (one per fleet) as a secondary CVBG anchor point (and the center of AAW and C4I operations).

Can you provide the original link to the rumor?

In its own class.

There is also an oversized Type 075 LHD.

But still no relevance to "Chinese Navy (PLAN) News & Discussions"

The Chinese Navy seems to be one step ahead of its Air Force sibling. No longer only following other footsteps but plan to create a new unique class of its own. Hopefully the PLAAF may arrive to that stage in near future, as the J-20 chief designer, Yang Wei, said in last interview during the Two Sessions, that he aspires for setting new standard in future!
