The Fearless-class patrol vessels were built by Singapore Technologies (ST) Marine for the Republic of Singapore Navy (RSN) in the 1990s. Four remain in service with the RSN as modified Sentinel-class maritime security and response vessels (MSRVs). Derivatives of the type are also in service in the navies of Brunei, Oman, and the United Arab Emirates.
