Yeas the ligth hulls of MCM is a douple edged sword really. In their main functtion, the GRP hulls are essential for mine advoinance and shock-resistance
(for example I remember that the Tripartie mine hunters superstructers are desinged so that if Mine blows them off, they just collapse like Japanese silkpaper walls during earthquake causing limited ammount of damage to the hull itself and to the equipment and personel)

But offcourse this brings issues when sailing in rough seas. But then again, AFAIK the mine hunting or sweeping isent task to be done in storms.

For the speed issue, its notable that the last MCM that soviets desinged, the Gorya class was intended to be quite fast 20kt+ for the same reasons stated above, but along with its other high demands the price of the ships rose into astronomical levels and the VMF simply havent afford to build them.

...wich remains me about the MCM role of the USN LCSs. Has there been any indications to use them as a fast fleet MCMs?

new pictures of 810 from its new base. I never actually noticed this before (because it's a MCM ship), it has one of the new Type 76F guns. Also, can someone explain to me what's all that stuff in the back of the ship? What are they used for? Golly?

Mechanical sweeping gear..no ROV, nor large crane to handle one...I think these are mented for traditional minesweeping, possibly has a sonar fitted.
But that doesen't make it obsolete, knowing PLANs own mine storages...Expecially knowing the old age of the bulk of the fleet.

The other new desing (not seen in here) is definetly a modern MCM desing with deckhouse and crane to support ROV usage and possible divers too.

well I dont know the exact english terms, but basicly they are the stuff that keeps the "trawling" lines on surface when sweeping mines in the good old fashioned way...float would be direct translation for the finnish term of such thing.
The smaller ones are most likely some sort of marker-floats that marks the safe fairway.

Buoy? Is that the term you are looking for?

解放军列装新型扫雷艇可突破强电磁干扰(组图)

  “扫雷先锋”失灵
  2年前,南海舰队某水警区一批新型扫雷艇列装,官兵们兴奋不已。为了使新装备尽快形成战斗力,在未来海战场上担当“扫雷先锋”,他们专门成立了新装备攻关小组,一边向有关科研单位、厂家请教,一边加班加点操练。4个月后,上级进行实际操作考核,各战位官兵动作娴熟。
  谁知,自鸣得意时,官兵遭遇当头一棒。这年冬天,水警区首次使用新装备参加演练。接到上级“扫除某水域水雷,为舰艇编队开道”的命令,3艘新型扫雷艇迅速前往某水域。然而,接近目标水域时,新型扫雷艇突然受“敌”强电磁干扰,指挥系统发生瘫痪,无法继续航行。“扫雷先锋”在“猎物”前蹩了脚,反成了 “猎物”……

“5分钟”带来的反思

  新型扫雷艇不听使唤了。水警区组织技术人员查找原因,折腾了一个星期,毫无结果。

  他们只好向生产厂家求援。5位专家风尘仆仆赶到,结果让他们忍俊不禁。原来,这种新型扫雷艇指挥系统内安装了一套防电磁干扰设备和备用操作系统。当有强电磁干扰时,官兵只要及时启动防电磁干扰设备和备用操作系统,就不会出现瘫痪的局面。专家进行简单调试后,设备恢复正常,前后仅用了5分钟。

  这引起了水警区党委“一班人”深刻反思:新装备训练不能走老路子,一定要把信息处理能力训到位,摸透新装备的“脾气”。党委会上,水警区司令员孟祥荣一针见血地指出:“要真正掌握新装备,就必须‘换脑’,全方位提高官兵的信息化素质。”

“换脑”换出战斗力

  痛定思痛,水警区首先把各扫雷艇艇长、副艇长分批送到厂家跟踪装备生产工艺流程,掌握装备使用要领。他们还邀请研究所专家讲授电子技术、信息技术等课程,丰富官兵信息化知识。在此基础上,他们采取循序渐进的方法,让官兵由低至高逐级熟练掌握各战位训练程序和内容,全面提高综合能力。

  与此同时,他们加强了新装备训法战法的研究,一方面进行网上推演,一方面把部队拉到陌生海域进行实装演练,探索多艇之间协同作战等课题。近2年来,水警区官兵先后攻克了新型扫雷艇技术难题30多项,创新战法训法10余项,总结出《新型扫雷艇常见故障100例》,摸索出《实战条件应急问题处置100 问》。

  日前,水警区参加上级组织的联合演练,新型扫雷艇大显身手,突破强电磁干扰,从发现目标到排除“障碍物”一气呵成,确保舰艇编队顺利通过“雷区”。

Basically, it talks about the new MCM ships learning to operate under strong ECM environment. It mentions the Type 82 class minesweeper (including 807, 811-813, possibly a few more 801-803?) and then there is this the improved minesweeper (328, 438, 840, 805, 810) and the minehunter 804.

another article on MCM training.
Talks about PLAN conducts mine detonation experiments close to warships for the first time. It talks about PLAN studying the mine laying patterns of foreign navies.

It talks about navy starting two new weapons projects (I think they are talking about 2 new mines here) last year and they were used for the experiments. It talks about speeding up the process of achieving IOC for new systems of submarines using simulations and such.
中国海军首次进行舰艇近距抗大当量战雷实爆试验
中国海军首次进行舰艇近距抗大当量战雷实爆试验

--------------------------------------------------------------------------------

2008年08月27日 来源:解放军报

--------------------------------------------------------------------------------


  今春,海军某试验场格外忙碌:一项大型试验任务刚完成,正在进行全面评估;某新型武器试验方法和大纲通过专家评审,试验即将展开;今明两年,多项试验任务已排满日程……对此,试验场政委刘广富深有感触地说:“学习贯彻科学发展观,头脑要有很强的机遇意识。我们紧紧抓住海军现代化发展带来的新机遇,站在了科学发展的新起点。”



  抢抓机遇,激活潜力解困境

  这个试验场是我国第一个水中兵器靶场,曾创造水中兵器试验领域30多项第一。但几年前却一度因试验海域不适应新型水中兵器试验需要,任务职能逐步萎缩,随之带来科研上不去、人才培养滞后等诸多问题。

  如何走出困境?2004年上半年,试验场党委连续4次专题研究并明确思路:海军新型装备快速发展带来了诸多新机遇,善于抢抓机遇才能拓展发展空间。恰在此时,他们得到消息:新型舰艇抗冲击研究项目马上就要展开。试验场主任宫国田立即带领课题组积极争取,并与该项目负责人接洽。

  “舰船抗冲击试验难度大、风险高,你们有哪些优势?”“我们有40年水下爆炸测量的丰富经验,有专门的技术骨干和设备,有集中配套的保障条件……”宫国田把家底抖了出来,还拿出了精心准备的论证报告。项目组随后组织专家到试验场考察,最终敲定将试验项目改在这里进行。

  推动转型,促进可持续发展

  在某型猎扫雷舰作战系统试验项目中,试验场第一次组织力量远赴某海域执行任务,出色地完成猎扫雷舰作战系统试验,一举填补了多项空白。为此,试验场领导引导大家打破传统观念的束缚,拓展发展空间,变“阵地战”为“运动战”,走出家门组织试验。去年,海军又有两型新武器试验项目上马。有关部门打破了以往由作战部队试验的惯例,将任务下达给试验场。

  在此基础上,试验场党委提出,建设海军水中兵器试验场和海上爆炸试验场,提高履行多样化试验任务的能力,推动试验模式和使命任务转型。高级工程师朱学文等人研究了大量外军潜艇作战样式和试验模式,编写出某新型潜艇作战、指控、战术软件等试验大纲,去年10月通过鉴定。新的试验模式,实现了潜艇武器系统试验由技术性能鉴定向作战效能鉴定的转变,将大大缩短新型潜艇战斗力生成周期。

  创新发展,练好手中金刚钻

  武器装备快速发展,必将催生一系列抗冲击试验任务。试验场党委看到了这个难得的发展机遇:试验场作为国内唯一的水中兵器试验靶场,要在“唯一”上下足工夫,进一步发挥优势,争取更大的发展空间。

  创新试验模式。]舰艇近距离抗大当量战雷实爆冲击,在我国尚属首次。他们成立课题组完成了试验总体技术方案、海上战雷布放实施方法等课题,多次战雷实爆试验成功实施,探索出了提高舰艇作战和生存能力的新途径。

  完善技术平台。试验场组织课题组展开科技攻关,研制成功某型信号监测设备、高精度水声定位系统、零浮力光电复合电缆等,为承担更多任务提供了技术支撑。

  锤炼人才队伍。近4年来,试验场与有关院校联合培养了2名博士研究生,引进了5名试验急需的博士。(特约通讯员 毛敬雄 记者 司彦文)

第一 本艇甲板已经全面涂抹了防滑层漆料,尽管看似稀松平常,却从另外一个侧面折射出军队建设的规范化,人性化;

第二 本艇虽为新艇,武器装备却是新老兼顾,这样就能更快的确保新装备生成战斗力;

第三 本艇造价约为2亿5千万,折合成美圆就是3700万左右。从参观的几个功能区可以判断,造价略高的根本原因还是部分核心装备的非国产化所致,在此我还是非常期待新艇的装备自给率能够稳步提升;

第四 最让我兴奋的是新艇已经装备有三种以上的卫星定位导航系统,其定位精度分别达到了*米以上 **米以下 和**米左右 ***米左右。大家猜是哪几种呢?
I thought it's interesting that the guy said class 805 is 37 million USD. And he says that the cost is so expensive because not everything is indigenous. He also mentioned that the ship has 3 types of GPS (i'm guessing GPS, Beidou and Glonnass). Not sure how much 804 class, but an Avenger class MCM cost almost 100 million in 1982 dollars or around 200 million in 2008 dollars.

about a new type of minesweeper in an exercise in South China Sea using new integrate sweeping equipment (I guess 805 class?). It describes a mission finding mine in level 6 sea condition. Talks about finding a target from 500 m out and getting closer to it until detonating it about 185 m away.
just usual propaganda piece.
新型扫雷舰在南海演练 投入新式联合扫雷具
来源:解放军报

  初冬的南海某海域,阴云密布,危机四伏。南海舰队某扫雷舰编队悄然驶入诡异雷场。

  这天上午10时许,海面骤起风浪,约6级阵风使战舰摇摆达30多度,不少官兵出现晕船呕吐。

  “组成扫雷队形,投放扫雷具!”10时40分,随着大队长胡平一声令下,某新型扫雷舰迅速驶进可疑海区,电磁音响扫雷具随即投放联合扫雷具。“扫雷具通电!”顿时,只见扫雷具发出强大的声频信号和电磁场,犹如强大引擎,向一切可疑目标发出诱爆信号。

  “我舰前方500米处发现可疑目标”。根据训练计划,扫雷舰要在水雷前方400米处将水雷扫爆。然而,舰艇逐渐向400米抵进,水雷却像睡着似的。胡平心里清楚,沉通水雷隐蔽能力强,不像一般的锚雷,它能识别扫雷信号和舰艇信号,智能化程度较高。

  坚持就是胜利!300米、250米、200米…… 越往前危险越大,稍不留意将舰毁人亡。而此处的海区情况非常复杂,暗流涌动,加大了工作难度。“加大扫雷具电磁磁场!”190米、185米……突然,前方水域传来“轰隆”一声巨响,水雷被成功扫除!

  挑战海况极限,成功扫爆沉通水雷让胡平笑容满面。新型舰艇列编近一年来,他组织大队官兵与科研院校专家教授、军兵种部队实行“捆绑式”训练,采取理论学习、战法交流、课题演练、实布实扫战雷等方式,在不到一年时间使新型扫雷舰形成战斗力。

  近2个多小时的3次海上惊雷,官兵感觉就像进入了险象环生的真实雷场,惊险而刺激。随舰指导的海军水雷专家也感叹不已:“海上趟雷勇者胜。趟了这么多年的雷场,跟随胡大队长这次演练最惊险、最贴近实战!”(王君 成斌 特约通讯员 周拥军)
