German shipbuilder ThyssenKrupp Marine Systems (TKMS) has launched the last of four Invincible-class (Type 218SG) air-independent propulsion (AIP)-equipped diesel-electric submarines (SSKs) on order for the Republic of Singapore Navy (RSN).

The vessel, which will be known in service as RSS Inimitable once commissioned, was launched on 22 April at TKMS' facilities in Kiel, Germany, the Singapore Ministry of Defence (MINDEF) announced in a statement on the same day.

“Conceptualised and engineered jointly by the RSN, Defence Science and Technology Agency (DSTA), and industry partner TKMS, the Invincible-class submarines are customised for operations in Singapore's shallow and busy tropical waters, and they possess longer endurance and higher payloads,” read the statement.

“Following the launch, Inimitable will undergo a series of sea trials before delivery to Singapore,” the ministry added, further disclosing that the second-of-class SSK that was launched in 2022, Impeccable , is still undergoing a series of local sea trials with plans to fully operationalise and commission it in 2024.
