May draw on some Submarine Matters info (particularly http://gentleseas.blogspot.com.au/2015/08/building-table-to-describe-soryu-to.html ) especially on when "LiBs" will be used in the Soryu. <br /><br />Seems to be a typo "The Soryu fleet includes six commissioned vessels, which have a surface displacement of 3,480 tons". That may be an estimate for current Soryu + 500 tons for future SoryuAU. The accepted figure for the Soryu is "Surfaced: 2,900 tonnes" https://en.wikipedia.org/wiki/S%C5%8Dry%C5%AB-class_submarine and http://www.globalsecurity.org/military/world/japan/2900ton-specs.htm <br /><br />I agree with the Geoff that "AIP" (most probably fuel cell) is necessary to extend the Future Sub's fully submerged range. I'd add that fuel cell AIP that works direct to motor might also be an important safety measure/backup in case of failure of the LiBs (which, after all, are a new technology for subs).<br /><br />Regards<br /><br />Pete Petehttps://www.blogger.com/profile/02624742078679760819noreply@blogger.comtag:blogger.com,1999:blog-19245896.post-20260311216896915662015-08-27T12:05:37.481+10:002015-08-27T12:05:37.481+10:00Hi S

I will use that in a Submarine Matters on the German bid, next week.<br /><br />Regards<br /><br />PetePetehttps://www.blogger.com/profile/02624742078679760819noreply@blogger.comtag:blogger.com,1999:blog-19245896.post-11392581716766876582015-08-26T02:57:34.586+10:002015-08-26T02:57:34.586+10:00Hi pete,

(1) Additional explanation on hull based ...Hi Pete<br /><br />(1) Additional explanation on hull based on reference picture [1] <br />Soryu hull structure is consisted of six arears from right-hand side head to left-hand side tail: i) first area (head) has double and single hull structures; ii) second, third and fourth areas have single hull structure; iii) fifth and sixth area have double hull structure. The double hull is consisted of the outer non-pressure hull (non-magnetic alloy) and the inner pressure hull (magnetic NS-80), and the single pressure hull is made of low magnetic NS-110, in my opinion. The inner pressure hull (NS-80) is not as strong as the single pressure hull (NS-110), because the outer hull (alloy) shows high strength. To realize over-all low magnetism of submarine without NS-110, new low magnetic and high strength steel is needed for the single pressure hull, i.e., fist partial area and second/third/fourth areas.<br /><br />(2)About management of ASC <br />I do not intend to criticize Australia at all. I just pointed out that there were major defects in the quality management system of ASC, which should be corrected whether Japan is selected as a partner of submarine development or not.<br /><br />(3)If you interested in German opinion, see reference [2](German).<br /><br />[1] http://livedoor.blogimg.jp/wispywood2344/imgs/8/b/8b3c1df9.png<br />[2] https://www.bayernkurier.de/inland/4720-deutsche-u-boote-fuer-australien<br /><br />Regards<br />S<br /><br />Anonymousnoreply@blogger.com
