Since Submarine Matters published Table Comparing Russian, German, French & Japanese Submarine Diesels, of March 15, 2018, Anonymous has done further very useful research and compiled new sets of data, figures and footnotes. These are marked in Blue with submarine diesels bolded.
Table 1 Specifications of modern diesels for submarine (as at March 20, 2018)
PETE COMMENT
As indicated on the Table, Japanese Kawasaki diesels have, by far, the highest mechanical and electrical outputs. An arrangement of four of these Kawasaki diesels would be more suitable for Australia's Future Submarine (SEA 1000) than a problematic six to eight lower powered MTU or MAN diesels.

ANONYMOUS'S COMMENT
As latest diesel, common rail fuel injection system, whose evaluation is yet established, is adopted for DM-185 and 12V4000 U83E. Output of DM-185 is not bad, but evaluation of vibration is not reported. If DM-185 shows good anti-vibration performance, it is very strong competitor of Germany or French diesels. Electrical output of DM-185 for submarine is 40-50% higher than those of German and French counterparts.
As indicated on the Table, Japanese Kawasaki diesels have, by far, the highest mechanical and electrical outputs. An arrangement of four of these Kawasaki diesels would be more suitable for Australia's Future Submarine (SEA 1000) than a problematic six to eight lower powered MTU or MAN diesels.
