The submarines are the second and third boats in a series of four Type 218SG submarines for the Republic of Singapore Navy.

They are among the most modern diesel-electric submarines and feature numerous customized solutions and new technologies.

According to TKMS, the vessels are designed with a low acoustic signature. The external air-independent propulsion system allows the boats to remain underwater for a longer duration.

With a length of approximately 70 meters and a displacement of around 2,000 tons, they are currently the largest submarines ever built at Marine Systems.

Once further intensive trials have been conducted, Impeccable and Illustrious will be handed over from 2023 onwards.

Following the double naming ceremony, thyssenkrupp Marine Systems and Singapore-based ST Engineering signed a teaming agreement. It formalized and strengthendd the long-term cooperation between the two companies.

The agreement covers both warranty services as well as in-service support for the four Invincible-class submarines, ensuring that they are well maintained in Singapore during their operational lifetimes.
