My comments in red.
Soryu-class submarines are the world's largest conventionally powered submarines. They have an excellent operational track record and are equipped with state-of-the art technologies, including air-independent propulsion (AIP) systems that enable them to remain fully submerged for long periods of time, and advanced stealth technologies (?) that make them extremely difficult to detect.
Major Specifications and Building Schedule of "Jinryu"
Specifications

Breadth: 9.1 m
Depth: 10.3 m
Displacement: 2,950 tonnes (submerged displacement: 4,100 tonnes)
Main engine: Diesel-Stirling-electric, one shaft (German license-built diesel, Swede license AIP)
Maximum output: 8,000 PS
Maximum speed: 20 knots
Complement: about 65
Armament and other equipment: Torpedo tubes, snorkel, submarine sonar system, etc.
Building Schedule
Keel laid: February 14, 2012
Launched: October 8, 2014
Delivered: March 7, 2016
(Nice schedule --continuous build--. Then again, Japan doesn't tolerate fools.).
Additional trivia on the Type 89 torpedo.
It is a wire-guided torpedo that features both active and passive homing modes. Compared to Mk-48 (ADCAP) torpedo, it is slightly longer (6.25 m to 5.79 m) and heavier (1,760 kg to 1,676 kg), but has a smaller warhead (267 kg to 295 kg). However, it can be used in the greater depth (900 m to 800 m).
A succeeding design is in development under the development name of "G-RX6".
So, on to Litium-Ion with the next Soryu. I hope that thing one of the expert readers mentioned about longer charging time isn't true. How much longer?
Australianization should be interesting...
