Since joining the Sri Lankan fleet in 1996 with the objective of enhancing the blue water capability of the navy. She served as its flagship and was deployed for patrolling the coastal water around Sri Lanka. Due to this she was attached to the 7th Surveillance Command Squadron. During the Sri Lankan Civil War, Parakramabahu was involved in anti arms smuggling patrols and maritime surveillance. During the war she was involved in several sea battles with the LTTE Sea Tigers, including the 1997 battle of the coast of Mullaitivu. However, its operations were greatly limited due to frequent breakdowns and the requirement of an escort of crafts from the Fast Attack Flotilla, and found itself spending much time in port and in non operational areas. Since early 2000, it was based at SLNS Dakshina in Galle, without going to sea due to breakdowns. It capsized and sank at its moorings at SLNS Dakshina when it was hit by the 2004 Indian Ocean tsunami. It was later re-floated by the Navy. It was damaged when the LTTE attacked SLNS Dakshina in 2006.
