The Republic of Singapore Navy (RSN) has taken delivery of its fifth Independence-class Littoral Mission Vessel (LMV), RSS Indomitable,  on 27 April. The vessel was ordered under a 2013 contract signed with ST Marine covering a total of eight ships. RSS Indomitable was launched in September 2016. The first three of the Independence-class ships, RSS Independence (15), RSS Sovereignty (16) and RSS Unity (17) were commissioned in 2017. The fourth vessel, RSS Justice, was delivered to RSN in November 2017.

80 metre-long Independence-class LMVs will replace the service's Fearless-class patrol vessels. The ships have a top speed of 27 knots, and a standard range of 3,500 n miles at 15 knots.
