The Bung Tomo class is a class of three Indonesian multi-role corvettes or 'multi-role light frigate' (MRLF) bought from Brunei by Indonesia.^[5]^[6] They were originally built for the Royal Brunei Navy (RBN; Malay: Tentera Laut Diraja Brunei, TLDB), and named Nakhoda Ragam-class corvettes, but were ultimately bought by Indonesia and subsequently renamed.^[7] The class is named after Bung Tomo, a noted leader of Indonesia's independence movement.
