Propulsion
For propulsion, the
S26 originally utilized four MTU 12V 396 SE84 marine engines, manufactured by
MTU Friedrichshafen.
[4] However, following a 2021 discovery revealing the dual-use of the German-made MTU engines on Chinese warships, in spite of a
European Union-imposed embargo restricting the sale of military technology to China, the export of the engines to both the submarines of both the PN and the RTN were consequently blocked.
[23][24] As an alternative to the MTU 12V 396 SE84, the CSOC reportedly offered a Chinese-made engine, dubbed the CHD620.
[4] Although it is currently unclear if the RTN has accepted the CHD620, several sources have reported that the PN had tested and accepted the engine.
[25]
In addition to the engines, the submarines are also set to be equipped with a
Stirling-powered air-independent propulsion (AIP), developed by CSIC’s 711th Institute.
[3] According to public information divulged by the CSIC, the
S26 is reported to have a maximum diving depth of about 300 m (984 ft 3 in),
a maximum submerged speed of 17 knots (31 km/h; 20 mph) and an estimated range of 768nm (or 20 days), while using AIP.
[22] The maximum range for mixed AIP and diesel-electric travel is 2000 nm, or 65 days.[22]

Can someone confirm the range of 2000 Nautical miles/2300 mile range ? This range is too low for these new subs? See links below to Indian major ports In Bay of Bengal. This is to make sure they can operate and target freely in Bay of Bengal.
Comments ?
If this is the case, these Subs cannot operate in bay of Bengal without a port call in the vicinity.

In Order to operate in Bay of Bengal they will need Sri Lankan port for refueling ? Comments
