With the Covert Shores - Popular Mechanics articles yesterday what can we learn about Japan's Future Submarine 29SS?:
29SS (see Table below) will be the lead boat in the new Japanese Kamikaze (神風 - Divine Wind) class submarine series. Mythical winds follow Japan's Oyashio (mythical currents ) and Soryu mythical dragons) class submarines.
The Kamikazes will, with the benefit of heavier, more voluminous, NCA formula Lithium-ion Batteries (LIBs) have longer (10 day) fully submerged performance .
Of course the Kamikazes (like the Australian under Attack class) will be as good as sunk against the superiority of Chinese and Russian nuclear propelled attack submarines (SSNs).
Hence Japan and Australia are currently, and will in future, be totally reliant on the whims of increasingly isolationist US SSNs to take on Chinese and Russian SSNs.
China's and Russia's increasingly sensitive fixed and mobile anti-submarine sensors demand more discrete performance from these Japanese and Australian diesel-electric submarines. But even with LIBs, these Japo-Aussie subs still need to loudly snort with supercharged diesel engines every 10 days. Thus blowing their residual discretion out of the water.
What might the new Kamikaze - 29SS class look like (courtesy H I Sutton's Covert Shores and anticipated by Submarine Matters on June 14, 2017 ):

With a pumpjet/propulsor and (Alfa, Akula slightly Type 212A) smaller, faired fin/sail on a Soryu looking hull (above). Inspired by artwork released by "Kobe Shipyard" (KHI, MHI, Japanese MoD) via Covert Shores (below):
