Leonardo Presents Its New OTO Marlin 40 Naval Defence System

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). Therefore, it is effective with different threats types, such as helicopters, uncrewed aerial systems and anti-ship missiles, thanks to its high accuracy, its capability to fire smart ammunition and a range of almost 5 km. The MARLIN 40 features light weight and compact dimensions 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 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. Low weight, no deck penetration, flexibility and reliability are just some of the features of its architecture. Its state of the art fully digital electronic allows a smooth integration with all the Combat Management Systems and Fire Control Systems available on the market.

In order to meet all customers’ needs, the system has been conceived in a basic version “Remotely Controlled” (RC), which can be managed by an external Firing Control System and in the advanced version “Independent Line Of Sight” (ILOS). The latter is a highly-effective precision-fire system, which can be operated autonomously via a local control console in addition to be fully controlled by the Combat Management System. The advanced sensor suite allows a 360° situational awareness of the environment. As option, the Marlin 40 may be equipped with an integrated hoist to enable the ammunition loading from covered position below deck. It is fully managed by an external Firing Control System by receiving the stabilized firing coordinates.

The Marlin 40 has been completely designed and developed by Leonardo. It is the result of extensive experience in the manufacture of advanced naval defence systems equipped with stat-of-art electromechanics and software technologies, able to comply technological progress and market trends. The Marlin 40 provides superior performance for challenging missions such as anti-missile defence, anti-aircraft warfare and ship-to-ship engagement. The gun features a dry weight of only 2,100 kg in its remotely controlled version, high maneuverability (the barrel can move at 120°/s thanks to powerful and accurate servo-systems), and the ability to fire multi-purpose programmable fused ammunition.
