The Sampari-class fast attack craft are a class of domestically designed and built fast attack craft operated by the Indonesian Navy. The ships also known as KCR-60 and all ships built by local company PT PAL in Surabaya. These ships are made with composition of aluminium and high-tensile steel in hull parts which are also a domestic product obtained from state-owned foundry PT Krakatau Steel in Cilegon.

History

Design problem

The Sampari-class batch-1 vessels have a relatively weak radar cross section (RCS). The BPPT Indonesia mentioned weaknesses in the shape of the upper building and the hull that were easily detected by enemy radar. The influence of electro-magnetic wave interference on the installation of several communication antennas on the ship will reduce the antenna performance in communication.

For the maneuverability, the Batch-1 ships are also considered less reliable to deal with in high waves on the ocean because the ships' size and the lack of fin stabilizer. This reduces the sea state-level capability of the ships. The endurance is also low as the ships can only operate on patrol for eight days.

The class were also smaller than required by the Indonesia Navy. To overcome these problem, BPPT Indonesia made some recommendations to improve the design of the batch-2 and batch-3 Sampari class.

Characteristics

Radars

The Sampari class is equipped with Chinese-made SR-47 search radar and TR-47 fire control radar. The later version were equipped with Danish Terma-made radar and fire control system.

Guns

Indonesia planned to arm the Sampari class with a 57 mm gun as the main armament but due to budget constraints, all four ships are now armed with a Bofors 40 mm as the main gun. For the secondary gun, the ships are armed with two Yugoimport-SDPR M71/08 20 mm cannon at the rear. In 2018, it is planned to replace the Bofors 40 mm with the Bofors 57 mm Mk.3.

Missiles

Sampari-class vessels were equipped with four C-705 anti-ship missiles. KRI Sampari and KRI Tombak were modified to give room for the installation of TR-47C fire control radar behind the main mast and one NG-18 (H/PJ-13) 30 mm CIWS at the stern.
