The Ijtihad class consists of four fast patrol boats[1] built by Lürssen Werft in Germany, and delivered to Brunei Darussalam in 2009.

A total of four Ijtihad-class fast patrol boats have been commissioned into service with the Royal Brunei Navy[1][3] (RBN; Malay: Tentera Laut Diraja Brunei, TLDB), where two of the ships began operating since March 2010, followed by another two on 28 August 2010.

[2][4] Two Ijtihad-class fast patrol boats arrived in Brunei Darussalam on 27 August 2010.

They are part of the project between the government of His Majesty The Sultan and Yang Di-Pertuan of Negara Brunei Darussalam and Lürssen Werft.

The commissioning ceremony of both vessels was officiated by Major General Dato Paduka Seri Haji Aminuddin Ihsan bin Pehin Orang Kaya Saiful Mulok Dato Seri Paduka Haji Abidin, Commander of the Royal Brunei Armed Forces (RBAF; Angkatan Bersenjata Diraja Brunei, ABDB).
