The Samoa Police Service operates the Guardian-class patrol boat Nafanua II. It was provided to Samoa by the Australian Government as part of the Pacific Patrol Boat Program. Nafanua II was delivered on August 16, 2019, replacing the original Nafanua, delivered in March 1988.
The original Nafanua underwent a $T5.5 million refit in Australia in December 2004. Between 1988 and 2004, the Nafanua sailed a total of 118,000 nautical miles (219,000 km; 136,000 mi), performed over 12,000 hours of fisheries patrol and has been involved in the search and rescue of over 400 people.
