Well, they don't build aircraft carriers any more . . . though the choice of the name Hyuuga for the 16DDH is quite amusing. I'm waiting for her sister ship to be named Ise.

Japan also has its own commercial nuclear power plants, 53 as of 2003, in fact.

This is one reason they agreed to basing USS George Washington (CVN-73) in Yokusoka starting later this year.

Japan -- which does spent nuclear fuel recycling -- certainly has the capability to build and support an SSN. Whether they would ever find the need for one is a separate issue.

I imagine that japan should be state of art about design and manufacturing of fuel cells. But they have chosen to buy swedish stirling engines.

AFAIK fuel cells should be much better for AIP on submarines. Stirling engines should be a bit more noisy!

But japan has bought stirling engines...

Any comment on this?

The JMSDF certainly has a potent force of SSKs...fast, quiet and well suited to the missions expected of them...a major asset in it's capabilties that it is increasing in various areas. Still, there are interesting developments in the region as a whole, especially when one looks at naval planning in Korea and China. It's certainly a fascinating part of the globe for naval development these days.

Yes, it is indigenous. I beleive all of the JMSDF's sub designs have been indigneous, though the Hayashios (early 60s) were modeled losely after the US Baracuda (K-1) class.

The JMSDF's submarine force is easily the most capable in the region, with large numbers of subs replaced at a very rapid rate. (in 2003, the oldest of the JMSDF's 15 combat subs was only 14 years old, and they had two dedicated training boats only 3 and 10 years old, respectively) Their subs seem quite...
