简氏披露中国改进型核潜艇比美潜艇静5分贝(图)

舆论注意到，这次台当局热炒“台海对峙”一事，正值两岸共度中秋佳节之际。台当局曾经屡次借元旦、春节等传 统节日刻意制造紧张气氛，达到某种目的。分析人士指出，台军炒作此事，其背后的目的可能是为大规模军购，特 别是购买潜艇制造气氛。

　　据悉，此次让台军高度紧张的“405”核潜艇是中国“汉级”核潜艇的第五艘。据英国《简氏防务周刊》披 露，该潜艇在动力系统、隐形性能、探测和攻击能力等方面比同级的
前四艘都有了很大的提升。

　　潜艇采用低速大扭矩直流电机直接驱动一个七叶大弯角螺旋桨，使最高航速由原来的25节，提高到了33节 。另外，由于安装了“减震浮筏”，大大降低了动力系统的噪音。航速33节时，其噪声是115分贝，低于美国 “洛杉矶”攻击核潜艇的120分贝。

　　“汉级”核潜艇使用核电推进方式。54万千瓦电池组充满电能后，可以关闭反应堆。电池组足以让潜艇全速 潜航10个小时，可以同美国的“海狼”级核潜艇媲美。如果以经济航速11节航行，更可潜航数百小时，噪声才 95分贝，接近海洋的背景噪音。

　　此外，由于装备了侦察声纳软件，该潜艇的测向精度大增，能边搜索边跟踪，同时攻击多个目标，性能方面达 到了世界先进水平。

Don't know how credible or significant is this report but it does quote Janes.
Looks like PLAN is still working on the old Hans. It claims the latest 5th boat is 115 decibel at 33 knots, better than LA class. And when the battery is charged, the reactor can be shut down. It can run at low speed of 11 knots for hundreds of hrs with 95 decibels, approaching the level of Seawolf.

no credibility at all, just your usual rumour on Chinese military sites. The worst part is that these news keep on getting recycled, so you see them popping up every few months.

Exactly! Well said Tphuang..We see the same old stuff over and over again. Post something new and fresh why dontcha?????

Why can't the PLAN do something like this..(this was previously posted) publish some up-to-date info like this article aboput the new improved sonar sensors on all USN subs. ?????.

I will tell you why. They have nothing new. Or they are very secretive. I thinks it's a combination of little of both...

that is how you be secretive...make the impression that they have nothing new

[sino52C]

I think it is more of combination of they don't have anything new.

Even if they do, the PLAN will still not have a SSN on equal terms with the Los Angeles or Trafelgar, or even the Akula.

And I'm not even talking about the Sea Wolf or Virginia.

Horray!!! #8 kilo is here, finally fufilling the contract that was signed four years ago. Personally, i think this is the last submarine china will recieve from russia, unless the russians make somethign really good.

ST. PETERSBURG. June 1 (Interfax) - The Admiralty Shipyards transferred a
diesel-and-electric-powered submarine of project 636 (Kilo) to China this week,
said the press service of the St. Petersburg Economic Development, Industrial
Policy and Trade Committee.

The first submarine was transferred to China in 2004. Overall, the shipyard
has built five submarines for China under a contract signed between
Rosoboronexport and the Chinese Navy in May 2002.

The contract is worth $1.5 billion. It was agreed that five submarines would
be supplied by the Admiralty Shipyard, two by the Sevmash shipyard based in
Severodvinsk in the Arkhangelsk region, and one by the Krasnoye Sormovo
shipyard based in Nizhny Novgorod.

The Admiralty Shipyards builds submarines and oil tankers.

Well, with all the fiasco of the way that the Russian shipyards going after this contract and with the delay in the delivery of the last sub. The Russians certainly did not leave any good impression on the Chinese. I guess if we do see another order from China, it would signal Yuan is not going too well. That would be a bad sign for sure.

From my point of view, I don't think the Yuan SSK will be less capable than the SONG. And the SONG class is a modern diesel submarine with overall excellent performance. I think the Chinese are very happy with the way SONG was designed and currently performs. Yuan is also obviously highly influenced by Kilo. China's shipbuilders have learned even more about sub construction since SONG went into production. So I think that Yuan will work out just fine.

The Russians were not very smart in dealing with this contract. I think the amount of time and support for the delivery of the Kilo's seemed rather poor. I wonder how it will make other interested parties view a substantial contract with Russia for weapons procurement for the future.

it's not just this. They were also suppose to deliver the second sov last year, but then it caught on fire. Apparently, they are still optimistic somehow about the situation. They would be lucky if China doesn't ask them for compensation.

Well it happens. Russians know that there costumers don’t have to much other options; where else could they buy equipment?
If you have money and you are not under sanctions you will do your shoping at West. If you don’t have that options only place where you can buy relatively modern equipment is Russia…
And it’s not like that sort of things happens only to Russians. Joust ask Thai navy about there frigates. They weren’t to happy whit Chinese workmanship but they knew that for that price they couldn’t expect better…

unfortunately for the Russians, with the way that the Sov and Kilo deals went down, I just can't see China placing another order. Those orders were put in 2002 in response to the package that George Bush cleared for Taiwan. It's hard to see the circumstances repeating themselves again.

Well maybe Russians don’t expect new orders after interdiction of new Chinese destroyers… Maybe they expect to sell only equipment to China.
If we may see current Chinese emphasis on locally built equipment then Russians are probably quite aware of that to.

I think these might be pictures of the transfer, but I cant be sure. looks like the pic was taken about a day or two before delivery, since the ship is near korea.

[crobato]

Do you also notice that the Indian navy also has pictures of the Kilos moving in the Indian Ocean, and noted it passed through the Malaccaas?

Now this Kilo taken by the Japanese Navy is moving from a completely opposite direction.

If some people don't understand what it means, it means that the 8 Kilos are indeed made from different shipyards all over Russia. The Kilos that passed through the Indian Ocean are those that were made in the northern shipyards and had to circumvent the Atlantic, while the Kilos that passed through the strait between Korea and Japan are those that were made in Siberian shipyards, to be more precise at the Amur region. These only had to make a much shorter trip.

Why disperse the sub production to different shipyards? Well, if one shipyard tried to make all 8 kilos, you cannot deliver them in the time requested. Probably around 2010-2012 instead.

[tphuang]

a new 039

[Totoro]

That's the second one? It is frustrating that no picture shows the propeller, could be very well its on purpose. Also, it looks quite compact. Do we know crew size for it? Dimensions?
