Key Points

  • Indonesia has selected BAE Systems 57 mm naval guns for four vessels in the KCR-60M class
  • The weapons will go on board two existing vessels and two under construction

Indonesia has selected the Bofors 57 Mk3 naval gun system from BAE Systems for four vessels in the KCR-60M class.

A contract for the weapon systems has been signed with state-owned shipbuilder PT PAL, which will be involved in the weapon's installation.

The Indonesian Navy (Tentara Nasional Indonesia - Angkatan Laut: TNI-AL) operates a class of four KCR-60M-class fast attack craft. The fifth and sixth vessels in the class are under construction at PT PAL's premises in Surabaya.

Citing information provided by a TNI-AL source, Jane's first reported in February 2018 that the country has selected the Bofors 57 Mk3 naval gun system for the KCR-60M.

The plan then was to install the gun system on the programme's first-of-class, KRI Sampari (628), for initial evaluation purposes. However, information from PT PAL and BAE Systems now confirm that the weapons will instead be installed on the third-in-class, KRI Halasan (630); fourth-in-class, Kerambit ; and fifth- and sixth-in-class, both of which have yet to be named.

The Bofors 57 Mk3 can handle up to 120 ready-to-fire rounds, with rate of fire of 4 rds/s. It has a maximum range of 17,000 m and can be loaded with the 57 mm Bofors 3P (pre-fragmented, programmable, proximity-fused) ammunition from BAE Systems, which enables the weapon to engage a numbers of threats, including shore targets, aircraft, and anti-ship missiles. The first unit is scheduled for delivery to Indonesia in 2020, while the final unit will be handed over in 2021.

On Halasan and Kerambit , the BAE Systems solution will replace older Bofors 40 mm cannons installed in the primary position. These ageing weapons were salvaged from the decommissioned landing ship tank (LST) vessel, KRI Teluk Semangka , as an interim measure to provide the KCR-60M vessels with a naval gunfire support capability.
