HMPNGS Rabaul (01) was the first Pacific Forum patrol vessel to be commissioned, in May 1987. She is not the first vessel of the class to go out of service, because her sister ship from Fiji RFNS Kiro was wrecked in 2016. She arrived in Port Moresby, for disposal, on October 24, 2018. The vessel was named HMPNGS Tarangau.
