Sg's "Invincible" Type 218SG class submarines to incorporate newer Sub technologies in the near future (as these technologies mature)
QUOTE
The PA will focus on co-developing next-generation battery technologies for maritime platforms, crucial for enhancing the efficiency and sustainability of underwater vessels. Additionally, it will facilitate expert dialogues in additive manufacturing to improve the production and maintenance of submarine components, underwater platforms, and other related technologies.

“The similarities in our submarines, U212A & U218SG, allow us to mutually benefit from each other’s experiences,” said Rear Adm. Czerwinski, highlighting the potential for practical advancements through a Programme Arrangement (PA) with BAAINBw.

The Type218SG submarines were built at the outset with expansion and upgrades or updates in mind as sub tech evolves rather fast. These updates or upgrades to the Type 218sg submarines are expected to be done in Singapore. This ensures that the Type 218Sg submarines remain at the forefront of the latest underwater capabilities.
Note 3: Sg is taking a cautious approach to lithium batteries i.e. it does not want to be the first in case of an underwater incident. Germany has one lithium battery equipped Type 212a submarine currently undergoing testing. Sg is waiting to see the technology mature and then retrofit them into the Type 218Sg submarines.

Potential problems with lithium-ion batteries include the fact they can be prone to combusting, generating a lot of heat, plus toxic fumes and conductive dust, all of which raise the risk of potentially deadly fires and other accidents.
