LOOK AT JAPAN'S NEXT
GENERATION SUBMARINE
S
commented here
on November 14 and 15, 2015 about Japan’s Next Generation Submarine which may be 29SS (no LAB, no
AIP, LIBs only). 29SS perhaps to be laid-down at MHI in 2018 for launch in 2020 (see 29SS in red in
Soryu Table above).
29SS is especially
important for Australia because it will be the first new generation Japanese
submarine that immediately precedes the submarine Japan is designing for
Australia (“1AU” also in red on Soryu Table). This is if Australia chooses Japan.
Prior to the Next-Generation Japanese Submarine being built there are many standard planning and budgeting documents and procedure to be completed years beforehand. The following gives a glimpse of some of the procedures and issues with the next-generation 29SS. S’s
specific comments with some English translation by Pete [S is invited to correct Pete’s translation if its meaning looks
incorrect]:
"Changes
of hull architecture as well as four major improvements (new torpedo, further
reduction of vibration, new sonar system, and enhanced snorkel system) will be incorporated
into the 29SS design.
[S
has provided a summary of the 29SS project plan.] "It is expected.
-
That 29SS will be nearly the same size as the Soryus [28SS and earlier – see Soryu
Table] but 29SS will have longer compartments than current Soryus"
[see diagram below - For first Australian sub if current AIP compartments (9 and 10) are deleted then that will allow all other compartments to be lengthened - including Crew's Accommodation (2) for longer bunks for the taller Australians, longer Torpedo Section (1) to take 2 or 3 UUVs as well as 20 HWTs. More space on lowest level for extra diesel fuel and Lithium-ion batteries (LIBs)]
- "The
performance of the 29SS design architecture including crushing [pressure hull
yield] strength will be demonstrated and validated based on experiments on the prototype
[does S mean 29SS is the prototype?]"
The
2012 Financial Year planning and authorisation document “FY2012 Policy Report
by Bureau of Finance and Equipment of Japanese Ministry of Defense” indicates:
"(5-1b)
Needs of implementation in FY2013
Inhibition
of enlargement due to the improvement of submarine performance is urgent issue
in terms of target strength and reduction of ship price. Since the result of
the study will be reflected in the newly designed submarine by conducting this
study from the FY2013, the study is needed to start in this [2013?] fiscal
year.
(5-1c)
Reason for non-application of existing organization and equipment.
Although
high density rigging [arrangement] of equipment [has been] carried out to
inhibit [limit] enlargement in modern submarine [the Soryu?], the [arrangement
has] already reached [the] limit. In the next generation submarine [29SS] with new
equipment such as the new sonar, enlargement of hull is a concern. For this
reason, the extension of length of compartments which contributes to the
streamlining of the equipment of submarine is being considered. The solution of
reinforcing the current pressure hull architecture with larger reinforced
materials is expected to cause enlargement and increased price of the next
generation submarine [29SS]. Adoption of new architecture is [therefore] needed.
(5-2)
Efficiency
In
this study, the system design required for the prototyping and evaluation of components
and equipment will be conducted, various models (machined model, welded
assembly model) will be prototyped, and their crushing [pressure hull yield] strength
will be measured.
(5-3c)
Confirmation of the effect
Prototyping
and testing will be conducted from 2013 FY 2015 and from FY2014 to FY2015,
respectively.
In
it is planned to carry out the test.
(6)
Timing of validation
Policy
assessment (post-project evaluation) will be conducted in FY2016.

LITHIUM SULFUR BATTERIES (LSBs or Li-S)
Energy density diagram comparing batteries including Lead-acid (LABs), Lithium-ion (LIBs) and Li-S or Lithium Sulfer (LSBs) in watt-hour per kilogram (Wh/kg) and watt-hour per litre (Wh/l). LSBs are projected to be superior. (Diagram courtesy Oxis Energy)

advised that:
"a few days ago, Japanese battery company GS YUASA announced (in Japanese language News Release http://www.gs-yuasa.com/jp/newsrelease/article.php?ucode=gs151114132202_191 ) that GS YUASA had succeeded in developing Lithium Sulfur Battery (LSB) with an excellent charge-discharge performance.
This LSB with lithium anode and sulfur/porous carbon composite shows high energy density of 1000mAh/g (In the case of Japanese submarine with voltage of 450V, 1000mAh corresponds to 450kWh which is 10 times bigger than current LABs. ) and inhibits reduction of capacity with charge-discharge cycle.
Submarines with LSB will show excellent performance from low to high speed regions. But, as metal Lithium is highly reactive to water, overcoming the safety issue will be a key element for practical application LSBs for submarine. Frankly speaking, it will be quite tough."

Pete Comment - So LIBs may be the new in-operation batteries for submarine from the 2020s while LSBs may be the next advance in batteries for use from the 2030s. Please connect with Submarine Matters http://gentleseas.blogspot.com.au/2015/06/li-s-or-lithium-sulfer-batteries-lsbs.html of June 1, 2015.
PMB Defence [LABs and LIBs]
A snippet - PBM Defence (Australia’s Collins current supplier of LABs) may be effected by the future
submarine purchase because the CEP may well be requiring Lithium-ion Batteries [LIBs] only. Possibly all 3 contenders in the CEP have approached PMB. See PMB mention on page 12 in this well produced brochure http://www.defencesa.com/upload/media-centre/publications/fac/3295/Techport%20Australia%20Brochure%20June%202015.pdf .

Hi Pete
I introduce another information on Japanese submarine: i) figures and table of compartment elongation, and ii) expected floating deck and shock resistant damper [2] as shock resistant system, one of four major improvements of 29SS.

Hi S
Thanks for those [Nov 16, 2015 11:38PM] details. I'll put them into an article next week.

Hi Pete
(About LSBs)
Theoretical capacity and energy density of LSBs are 1672mgA/g and 2567Wh/kg, respectively. Latest laboratorial value of energy density is around 1300Wh/kg which reduces to 1000Wh/kg after 50 charge-discharge cycles. Practical but limited application of small LSBs in near future is expected.
(About floating deck)
According to Japan Maritime Self-Defense Force (JMSDF), floating deck is not new concept and has been adopted for US nuclear submarines more than two decades ago. I do not know why floating deck was not adopted until now.

LIBs, LABs, LSB, ...
It's getting cold in Germany and I have to replace the LABs on my car.
I'm writing this on a mobile phone. Before there are no mobile phones with LSBs submariners should keep off such batteries.
Why are there no LIBs for cars as a starter battery? Price and or stability?
For submarines LIBs are not an easy solution. A sub with full charged batteries may have twice the endurance of LABs (exotic LIBs are too expensive); with LIBs also replacing an AIP maybe three times.
Then the sub has to surface and recharge two or three times the capacity of LABs. With the same old engined about 2 or 3 times longer recharging times. Or the same surface time without any gain for submerged travel.
For long enduring submerged missions only a real AIP works properly like a fuel cell system or a nuclear reactor. Due to several reasons the nuclear option is not suitable for Australia.

Hi Pete & MHalblaub
According to the researches of LIBs, development of LIBs for electric/hybrid electric vehicle is very important. Although anode materials are developed, conventional cathode materials have some issues such as low capacity, high cost and low conductivity to apply electric/hybrid electric vehicles. Practical capacity of current LIBs is 100-180mAh/g, but, LIBs with high capacity (270mAh/g) and high capacity retention (92% after 140charge/discharge cycles) are reported. In future, LIBs vehicle will be realized.
AIP is suitable for surveillance with low speed (less than 4knot/h) and long time, but is not suitable for battle field which needs fast motion, because AIP cannot produce huge amount of energy at once.
Regards
S
Hi S and MHalblaub
I think the best way to perfect LIBs for submarine is rigorous testing on subs and then operational use.
In the case of Japan years of LIBs on 27SS onwards will increase Australia's confidence by the time (5 years later) that LIBs will be fitted to any Japanese designed subs for Australia.
If Australia is the first LIBs user on winning Shortfins or 216s this first use will present a considerable risk for the Australian customer.
So Australia will be the LIBs guinea pig if it chooses DCNS or TKMS but certainly safer if it chooses Japan.
Regards
Pete
