Wong noted the necessity for the Singapore Armed Forces to adapt to new types of warfare, including cyber threats and technological advancements.

The Invincible-class submarines are equipped with air-independent propulsion systems, allowing them to remain submerged for extended periods while maintaining a low acoustic signature.

Singapore has officially commissioned two advanced submarines, the Invincible and the Impeccable, to bolster its naval capabilities.

During the commissioning ceremony at Changi Naval Base, Prime Minister Lawrence Wong emphasized that the new submarines are quieter, more durable, and better armed than their predecessors.

This acquisition is part of a broader strategy aimed at strengthening maritime defense and ensuring national security amid rising regional tensions.

Ordered from ThyssenKrupp Marine Systems in Germany, the submarines represent Singapore's fifth and sixth submarines, with a total deal valued at approximately 1 billion euros.

While the new submarines are technologically advanced, experts have pointed out that they may lack the firepower of regional competitors like Vietnam's Kilo-class submarines.

The commissioning of these submarines occurs alongside a regional trend, with neighboring countries such as Indonesia and Malaysia also enhancing their submarine fleets.

Ultimately, the Singapore Navy aims to maintain a technological edge over potential adversaries through these significant advancements in its submarine capabilities.

Designed specifically for Singapore's operational environment, these submarines take into account the increased salinity and warmth of local waters.

Each submarine measures 70 meters in length and displaces 2,200 tonnes when submerged, requiring a crew of only 28 due to advanced automation.

The submarines also feature dedicated facilities for female personnel, promoting greater female integration into the Navy's submarine crew.
