Two refurbished Republic of Singapore Navy (RSN) patrol vessels are now back and ready to more effectively defend Singapore’s waters after being equipped with new capabilities such as improved ballistics protection, as well as better audio and visual warning systems. The Sentinel-class Maritime Security and Response Vessels (MSRVs) are part of a new Maritime Security and Response Flotilla inaugurated yesterday. Associate Research Fellow Ben Ho from the RSIS said the MSRV’s wide range of capabilities turns it into something like the “Swiss army knife” of maritime constabulary vessels. “This makes it well suited to handle the spectrum of challenges maritime forces may have to grapple with today,” he said.
