In a notable article INDAILY Adelaide’s independent news, February 21, 2019 reported:
That Jean-Michel Billig, Executive Vice President, Future Submarine Program [Naval Group] and Member, Naval Group Executive Board in translation, made the very significant comment that:
“Diesel generators [for Australia’s future Attack class submarine] will be German...”
COMMENT
[At 4,500 tonne (surfaced) the Attack class submarines will probably need to achieve a diesel output of 6,000kW requiring at least 4 x 1,500kW diesels]
From the "will be German" diesel statement Anonymous [with some further translation by Pete into more correct English] on February 27, 2019 calculatedAustralia’s future Attack class submarines may use the following German diesel designs:
specifically the MTU 12V 4000(mechanical output=1300kW,
OR
B. MAN Energy Solutions (MAN based in Augsburg, Germany) formed 2010 from merger of
MAN Diesel and MAN Turbo.
MAN Diesel and MAN Turbo.
specifically the MAN 12 PA4 V200SMDS (1330kW, 25.8MPa).
Note that the MAN 12 PA4 V200SMDS has a slightly lower Pme and a longer but lower rotation or piston speed (1300rpm, 9.1m/s) than the MTU 12V 4000 (1800rpm, 11.2m/s). But if the 12 PA4 V200SMDS is modified (such as common rail injection system), it may achieve about 1500kW of mechanical output by 10% increase in Pme. Higher boost modification depends on the selling price.
It is unlikely the older MTU 16V396 will be used as its Pme is low at 20.5MPa.
[1] seeMean effective pressure (Pme)is a valuable measure of a reciprocating engine's capacity to do work that is independent of engine displacement. Higher Pme means better performance. Pme = 8 x E / (3.14 x N x S x D^2 x H). Where, Pme = brake mean effective pressure, E = mechanical output, N = number of cyliders, D = cylinder bore, H cylinder stroke.

PETE COMMENT
Penske Power Systemssupplies MTU and MAN diesels for marine and defence applications in Australia with branches all over Australia including Adelaide (where the Attack class submarines are being built).
