At PACIFIC 2015, the international maritime exposition currently held in Sydney Australia, the Japanese Government and Industry held an industry briefing on its bid with the Soryu for the SEA1000 program. Japan has a small pavilion at the exposition with scale models of the SEA1000 proposal, a Soryu class, an Atago class Destroyer and the 20DX Frigate.

The briefing which Navy Recognition was attending was presented by Japan's Defence Ministry spokesman Masaki Ishikawa and Izumi Ishii, Vice President of Integrated Defence & Space Systems at Mitsubishi Heavy Industries Ltd.
The Team Japan as presented by the Defence Ministry spokesman is to incorporate state of the art technologies from both Australia and Japan into proven technologies for ocean navigation, to work with local industries in whatever arrangement best suited for the Australian Government and to involve Australian industries from the design phase throughout the program.

According to Izumi Ishii, the submarine offered for the Australian SEA1000 program will be "a quite different submarine compared to the Japanese Soryu because of its American combat system, larger size and increase range but it will have some commonality with the Soryu".
MHI envisions two design centers: One in Japan and one in Australia with a growing Australian portion as the program transitions from concept design to basic design and eventually detailed design. A full scale mock-up of the submarine would be built in Australia for basic training (but no shore integration center is planned for now).
While both MHI and KHI (Kawasaki) build Soryus for the JMSDF, only MHI is involved in the competitive evaluation process for SEA1000.
The Japanese government has set up a website to help Australian companies getting in touch with Japan industries for the program. MHI will be conducting 1 on 1 meetings with companies accross Australia over the next few weeks.
["Anonymous" in Comments [October 12, 2015 at 5:17 PM] indicated SEA 1000 Concept (in the diagram above) shows double layer arrangement of future Lithium-ion Batteries (LIBs) (the Current Soryu adopts single layer arrangement of existing Lead-acid Batteries (LABs), and adopts [very difficult] Gas Tungsten Arc Welding (GTAW), Gas Metal Arc Welding (GMAW) and Shield Metal Arc Welding (SMAW), I think. Training of welders will be crucial element of technology acquisition, especially for NS110-GTAW.
Anonymous added that the Japanese Ministry of Defence (MOD) may release a list of subcontractors which is partially disclosed. Translation and understanding of NDS (MOD Standards) are also very important. There are so many things to do.]
["S" in Comments [October 12, 2015 at 5:22 PM] indicated (along the lines) that Japanese research on new main batteries for submarine revealed that the energy density of LIBs was twice that of LABs and lifetime of LIBs was 1.5 times that of LABs.
But, from analysis of “Life Cycle Cost (LCC) Management Reports on 23SS (LABs-Soryu) and 27/28SS(LIBs-Soryu)” and other budget papers, S concludes that the life time of current LIBs will be twice that of LABs [that is higher than "1.5 times"] and that prices of LIBs will be high. When adding 24-years of operational life of 22 Japanese submarines with 30-years operational life of the 8 Australian submarines, more than 300,000 LIB unit cells will be needed. There may be a reduction in the price of LIBs caused by mass production effects.]
Reduction of LIB prices may also occur due to much more diverse and frequent non-submarine uses such as:
- in UUVs for civilian and military purposes
- in large land vehicles (eg. trucks for mining) as well as cars and- much more common Tesla like (solar to battery) static use on an industrial scale.
Cost of LIBs will, of course, be one item in the many items that make up the submarine's up-front, training, running and other maintenance costs.
Right up until the winner is announced Japanese delegations will likely be travelling around Australia to promote their SEA 1000 solution to politicians, the RAN, businesses and wider public (through the media). Delegations will also be more widely discussing industrial alliances with businesses in all Australian states and territories (as all will likely be involved in the build).
Thankyou Navy Recognition for use of your report.
