Sentinel-class patrol vessel

The Sentinel-class offshore patrol vessel (OPV) is a class of four ships being constructed for the Republic of Singapore Navy (RSN), which will succeed the Sentinel-class maritime security and response vessels. The OPVs are scheduled to be delivered progressively to the RSN from 2028. German firm Fassmer will develop the class, while Western Baltic Shipyard will build the ships, before Fassmer commences the fitting out process.
