On November 25, 2024, the Republic of Singapore Navy (RSN) officially decommissioned its final Challenger-class submarines, RSS Conqueror and RSS Chieftain, marking the end of an era for Singapore's naval defense. The ceremony, held at RSS Singapura – Changi Naval Base, symbolizes the transition to the RSN's new Invincible-class submarines, designed to enhance undersea warfare capabilities. These modern vessels, built by Germany’s ThyssenKrupp Marine Systems, feature air-independent propulsion, noise reduction technology, and advanced armament systems, positioning Singapore as a key player in the competitive Asia-Pacific maritime landscape. The move underscores Singapore’s commitment to strengthening its naval power in response to growing regional submarine developments and ensuring the protection of its critical sea lanes.
