MINDEF has signed a contract with Fr. Fassmer GmbH & Co. KG (Fassmer) to acquire four new Offshore Patrol Vessels (OPVs) to replace the existing Sentinel-class Maritime Security and Response Vessels (MSRVs).

The ships are based on a proven OPV design operated by the German Bundespolizei (Federal Police), and are designed with high manoeuvrability to operate in Singapore's congested waters, and equipped with a suite of lethal and less-lethal capabilities to provide flexibility and calibrated response against a wide spectrum of maritime threats.

The four OPVs will be delivered progressively from 2028 onwards. The MSRVs will remain in operational service until the OPVs are delivered and operationalised.
