GEC-Marconi in 1995, and the ships, a variant of the F2000 design, were launched in January 2001, June 2001 and June 2002, at the then BAE Systems Marine yard at Scotstoun, Glasgow in Scotland. Brunei refused to accept the three Nakhoda Ragam-class corvettes from BAE Systems. The contract dispute became subject to arbitration and was settled in BAE System's favour. The vessels were handed over to Royal Brunei Technical Services (RBTS) in June 2007. In 2007, Brunei contracted the German Lürssen shipyard to find a new customer for the three ships, and the ships were eventually purchased by Indonesia

offshore patrol vessels (OPV) from Lürssen, the same company that Brunei contracted to sell the Nakhoda Ragam-class corvettes. Keel laying for the first two vessels of this new class took place on 26 June 2009 at Lürssen shipyard in Germany. The first tranche of two vessels were launched 12 November 2010 and delivered to the Royal Brunei Navy in January 2011,^[3][4] while the second tranche of two vessels were delivered by 2014
