Four Invincible-class submarines are being built by German shipbuilder ThyssenKrupp Marine Systems (TKMS) for the Republic of Singapore Navy (RSN).
The submarines, also known as Type 218SG, will replace the RSN’s current Archer-class, and Challenger-class submarines that were built in the 1960s.
Named Invincible, Impeccable, Illustrious, and Inimitable, the four diesel-electric submarines will be a part of the RSN’s submarine long-term capability development and force renewal programme and will also meet its operational requirements.
