Japan should protect tech secrets in Aussie submarine bid
TOKYO -- Japan's leading shipbuilders
and
are strongly promoting their technological strengths to Australia in a bid to win contracts to build that country's next generation of submarines. Mitsubishi Heavy said that it is considering building all the vessels in Australia, but hurdles remain, such as how to train local engineers in such a short period of time. Management of costs and protection of technological secrets are also major concerns.
Toshihide Yamauchi, councillorat the Taiheiyo Engineering, a Tokyo-based defense-focused consultancy, discussed how the Japanese camp can prepare for these challenges, in a recent interview with The Nikkei. Yamauchi previously served as captain of the Japanese submarine Setoshio.
Q: Compared to the German and French rivals in the bidding, what are the advantages of the Japanese submarines?
A: The Japanese submarines can dive much longer without having to surface. This is a significant technology. Japan's Ministry of Defense has said it plans to replace conventional lead-acid batteries with more powerful lithium-ion cells, which will enable the vessels to cruise at high speeds underwater.
The Japanese submarine is as capable in combat as the German boats. Our country is also advanced in combat systems (which can pick out specific sounds of the enemy from surrounding noise and conduct operations based on this information). In addition, Japan has a well-developed supply chain for submarine building. There are companies that can custom-make even a single screw for a submarine..... to read more
