[MTU?] reluctant to supply diesels for future Pak Subs
The following very brief article is about German diesels for submarine [MTU being the one and only German maker?] which might not be supplied for Pakistan's future submarines.
I doubt if the germans can permanently hold off... I think it is not such a big issue
Compared to the 2010 doc below, the engine choice has narrowed as Paxman and Pielstick are MAN owned which leaves a duopoly of MTU and MAN with MTU enjoying strength...e.g. Indian scorpenes use MAN supplied DCNS installed Pielstick.
As technology of MTU diesel for submarine is protected by a bunch of patents, its imitation is difficult without violation of the patent law. But, China does not respect the law as shown [1]. In the case of diesels in submarine, third parties except customer and supplier cannot prove the violation of the law.

Re your "I doubt if the Germans can permanently hold off". True.
For Germany/MTU/MAN, given China is a big marine engine customer, I'd say the pause on submarine engines end-used by Pakistan will be temporary. See importance of China as a MTU customer https://gentleseas.blogspot.com/2014/06/german-diesel-engines-and-aip-for.html .
Thanks for http://bmt-defence.com/media/6097991/BMTDSL-Multiengine-submarine-power-supplies-Pacific10-Jan10.pdf a very well written, enlightening paper.
Oh the Hedemora for Collins decision...#$&@$$$
Apparently Naval Group is doing the right thing by using MTUs for the Attack class. Maybe MTU 4000s or 396s see https://gentleseas.blogspot.com/2019/04/australias-attack-class-submarine.html
Yes MTU's patents may slow down supply of MTU 4000s or 396s for Pakistani subs.
BUT note Rolls-Royce and China Yuchai Jointly Produce MTU Engines https://www.prnewswire.com/news-releases/rolls-royce-and-china-yuchai-to-jointly-produce-mtu-engines-300222849.html - China Yuchai International and Rolls-Royce Power Systems formed a joint venture in China - Producing MTU 4000 (good for submarines etc) engines from 2017 in Yulin, China - Capacity is up to 1,500 engines a year with components produced in Germany and China
I think Chinese produced MTU engines may already be used in Chinese Song and Yuan class submarines https://gentleseas.blogspot.com/2018/03/german-russian-dm-185-submarine-diesel.html .
It is 8 Yuan class variants that China is building/supplying parts for Pakistan https://en.wikipedia.org/wiki/Type_039A_submarine#Export.

https://www.hedemoratd.com/ (might ring a bell to Ozzies as it is used in the Collins Class)
PS: The timesnow tends to be quite shrill and frankly sensationalist...so I would not take them very seriously...
