The Nakhoda Ragam class is a class of 3 Indonesian corvette offshore patrol vessels. They were originally built for the Royal Brunei Navy but were ultimately bought by Indonesia.[3] The class is named after the original name of the lead ship of the class, a legendary Malay seafarer, Nakhoda Ragam. The lead ship has since been renamed after John Lie a National Hero of Indonesia, one of the first high ranking navy commanders during the Indonesian National Revolution.

The three vessels were built by BAE Systems Marine (now BAE Systems Maritime - Naval Ships). The contract was awarded to 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. The customer refused to accept the vessels and the contract dispute became the subject of arbitration. When the dispute was settled in favour of BAE Systems, the vessels were handed over to Royal Brunei Technical Services in June 2007.[4]

In 2007, Brunei contracted the German Lürssen ship yard to find a new customer for the three ships; in November 2012, it was announced that Indonesia had signed a memorandum of understanding with Britain to acquire the vessels for one-fifth of the original unit cost.[5] The ships are expected to enter service with the Indonesian Navy by 2013–2014.[6][7]

The ships were originally armed with MBDA Exocet Block II anti-ship missiles and MBDA Seawolf air defence missiles. The air defense missile system has been replaced with the more modern VL MICA, because MBDA has stopped producing the Seawolf missiles. The main gun is an Oto Melara 76mm; the ship also carries two torpedo tubes, two 30mm remote weapon stations and has a landing spot for a helicopter.[8]

The naming of KRI John Lie memorializes a National Hero of Indonesia, was one of the first high ranking navy commanders during the Indonesian National Revolution.
