KA Tun Azizan is an auxiliary ship currently in service with Royal Malaysian Navy (RMN).

[1][2][3][4] Petronas, together with MISC Bhd and Malaysia Marine Heavy Engineering (MMHE), has converted Tun Azizan, a cargo vessel, into a mobile sea base ship with the necessary features to function as a long-term national security asset following the incident of armed group invasion in Kg Tanduo, Lahad Datu, Sabah on 12 February 2013.

In November 2014, Petronas led an initiative jointly with MMHE and MISC to convert a used cargo vessel for the Royal Malaysian Navy's use as a mobile forward operating base in Sabah.

All features and equipment have been fitted according to the technical requirements of the Malaysian Armed Forces (ATM).
