Dorang class is a patrol boat class of the Indonesian Navy, also known as Type PC-60 or PC-60M patrol boat. It was developed from KCR-60M and PC-40 designed and built locally across various Indonesian shipyards.[2] It is an indirect successor of FPB-57 class in terms of size and tonnage.
As of December 2022, two vessels of the Dorang class already in active service with four other under construction. When Indonesia is in a state of emergency, the Dorang-class patrol boats can be modified to be equipped with anti-ship missiles.[3]
Background
During the appointment ceremony of Indonesian Navy's then Eastern Fleet Command chief of staff, Rear Admiral Darwanto on 23 January 2015, Indonesia's then Chief of Staff of the Navy, Admiral Ade Supandi stated that to prevent illegal fishing by foreign commercial vessels in eastern Indonesia, the Indonesian Navy needs at least 15-20 patrol boats operating every day. The performance of elements of military force also needs to be intensified so he concluded that the Indonesian navy needed 40 new patrol boats with a size of 60 metres (200 ft). But for the initial stage, he projects to acquire at least 22 patrol boats first through a gradual procurement process, and also aims to replace older patrol boats.[4]
On 31 August 2022, the first two PC-60 patrol boats were inaugurated by Admiral Yudo Margono with Dorang (874) being the lead ship for the class.[5]

In addition, two 12.7 mm heavy machine guns were also installed on the right and left sides of the hull as a defense weapon against air attacks. This ship can be fitted with anti-ship missiles at the stern if required in further modification.[3]
