Leonardo‘s Marlin 40 naval remote weapon system has been selected to equip two Indonesian Navy PC60 fast patrol boats currently under construction at PT Caputra Mitra Sejati shipyard. This follows the procurement in 2021 of four Marlin 40 systems for two PC60 vessels and two Teluk Bintuniclass tank landing ships (LSTs). Both PC60 and LST will be equipped with the Marlin 40 Independent Line of Sight (ILOS) variant, the most feature-rich version of the turret. Further PC60 and LST vessels are expected to be built by Indonesian shipyards for the Navy. The Marlin 40 turret is a fully digitized system. It is lightweight, compact and easy to integrate. This means that the turret can be integrated onto all types of naval platforms as a primary or secondary defence system. Capable of anti-air and anti-surface defence, the Marlin 40 has a range of over four kilometres, is ITAR-free and can integrate with all currently-available naval Combat Management Systems (CMS).
The ILOS variant of Marlin 40 chosen by the Indonesian Navy is a highly-effective precision-fire system which can operate autonomously via a local control console. This brings together and processes the targeting data received from the turret’s own dedicated electro-optical system, external fire control systems and ship’s data, ensuring precision while incorporating a level of redundancy. The electro-optical director can rotate independently of the line of fire to deliver panoramic surveillance through a highly accurate sensor suite comprising a daylight camera, an InfraRed (IR) camera and a laser range finder.

The MARLIN 40 uses a recoil-actuated machine gun, fed by an automatic system able to manage two different
types of rounds selectable as a function of the specific threat. The MARLIN 40 can fire all types of 40L70 ammunitions, including those with programmable fuzes. The MARLIN 40 is equipped with powerful servosystems, stabilized in both azimuth and elevation, and a stealth shield to minimize the RCS and allow the operation in the most severe environments. The MARLIN 40 is a state-of-the-art technology naval gun system aimed to confirm the Leonardo’s leadership in the 40 mm calibers segment thanks to its outstanding performances suitable for Anti-Surface Warfare (ASuW) as well as Anti-Air Warfare (AAW).The MARLIN 40 features light weight and compactdimensions such to make it installable on a wide variety of surface vessels as primary or secondary armament and allow ease of integration with existing Combat Management Systems and equipment.
The Marlin 40 is the latest addition to Leonardo’s portfolio of naval defence systems and is in service with 30 naval forces worldwide. In addition to the ILOS variant, Marlin gun is available as a 40mm RemotelyControlled turret. Leonardo also offers the Marlin 30 in three variants: RC (Remotely-Controlled), COAX (Coaxial Electro-Optical Sensor Suite) and ILOS (Independent Line of Sight). The Electro-Optical Director can rotate independently
of the Line Of Fire for a panoramic surveillance through a highly accurate sensors suite (with an automatic tracking functionality) constituted of a daylight camera, an IR camera and a LASER Range Finder. A muzzle velocity RADAR can be integrated to optimize the ballistic calculation. This configuration could be also fully controlled by the Combat Management System, with target acquisition, target engagement and firing that are performed by the
CMS itself.
