Fire Power for Inner Layer Defence Systems
- The Oerlikon Millennium Gun uses a 35mm revolver cannon and is a multi-mission weapon system designed for a wide operational spectrum covering anti air, surface warfare and fire support, offering multi-role capabilities in one gun mount.
- The 35mm Millennium Gun with its unique Ahead air burst ammunition is a multi-mission, inner layer defence system (ILDS) capable of defeating anti-ship missiles and aircraft, multiple fast-attack surface craft, jet-skis and near-shore land targets in littoral and riverine waters. Additionally it is also effective against submarine periscopes, offering an ASW capability. The 35mm Millennium Gunextends ship self-protection to ranges greater than any close-in weapon system.

Oerlikon Millennium Standard Gun Mounting
- The Millennium Gun is an unmanned, remotely controlled gun mount and is compatible with modern and legacy sensor and fire control systems.
- Designed as a modular system without through-deck penetration, the Millennium Gun can be fitted on any number of ship classes. When delivered in the standard mounting configuration, the Millennium Gun is bolted to a deck flange via the supplied interface ring.

Oerlikon Millennium Gun with Ahead Ammunition Technology
- With its high rate of fire the Oerlikon Millennium Gun is designed to exploit air-bursting Ahead ammunition. The Millennium Gun fires 35mm ammunition, including the Ahead round, at 1,000 rounds per minute, which delivers a payload mass of 500kg per minute.
- On the basis of hit probability, Millennium can defeat anti-ship missiles at ranges 3 to 4 times larger than those achieved by close-in weapon systems.

OERLIKON REVOLVER GUN® MK3
- This remote controlled, high precision 35mm air defence gun with integrated radar tracker and electro-optical sensor unit is a powerful, autonomous shooter suitable for various kinds of missions.
- The Revolver Gun Mk3 can receive and process target data from 3D or 2D search radars or higher order control systems. The tracking radar’s automatic search pattern makes target handover simple, fast and reliable. The integrated gun control computer manages target tracking and engagement.
- The integrated 35mm Oerlikon Revolver Cannon® provides superior fi repower and accuracy. Combined with the Oerlikon Ahead® air burst ammunition the gun achieves a high effectiveness against a wide range of air threats, including low, slow and small (LSS) targets, UAS, artillery rockets, mortars and air-to-ground missiles.

OERLIKON SKYNEX® CONTROL NODE 1
- The Skynex Control Node 1 houses the computers and operator consoles of the Skymaster Battle Management System in a 20 feet container equipped with power supply, air conditioning, protection and communication systems.
- The Skynex Control Node is designed to be operated by four operators, an operations offi cer, two target operators and a technical operator. In order to increase the maximum amount of simultaneous target engagements, two more target operator consoles can be installed.

OERLIKON MULTI SENSOR UNIT
- The Oerlikon Multi Sensor Unit (MSU) is the next generation sensor unit for ground based air defence. It can be installed on a wide range of platforms and is equally suited for stationary or rapid deployment missions. The fully automated MSU is remotely controlled from the Oerlikon Skynex® control node or from a third party battle management system.

OERLIKON X-TAR3D® TACTICAL ACQUISITION RADAR
- The X-TAR3D is a three-dimensional multi-mission X-band search radar. As a light and mobile tactical acquisition radar it is ideally suited for short and very-short range air defence systems such as the Oerlikon Skynex® Air Defence System.
- The X-TAR3D performs the search, detection, acquisition, tracking and identification of high and low-altitude air targets, in order to provide the Skynex Control Node with a coherent three-dimensional air picture.

OERLIKON AHEAD® AIR BURST TECHNOLOGY
- The Revolver Gun Mk3 and the Twin Gun GDF009 TREO both rely on the proven Oerlikon Ahead® Air Burst Technology to achieve the highest possible kill performance for small air threats and in particular for RAM threats and drones. The Ahead ammunition carries a payload of subprojectiles, which is ejected at a pre-determined distance ahead of the target, with the objective of achieving an optimal subprojectile
density for maximum effectiveness.

FUTURE SKYNEX EFFECTORS
OERLIKON HIGH ENERGY LASER
- For more than a decade, Rheinmetall has been working on new weapon technologies such as the high energy laser. Its scalable degree of escalation, the low cost per engagement and the extended engagement range make it the ideal weapon against unmanned aerial systems, in particular drones and other low, slow and small targets that come in masses. Integrated into the Skynex Air Defence System, the high energy laser certainly adds a first level of saturation resistance that is well required looking at the future threat scenarios.

OCWSB Pratama Indonesia is offering highly specialized service and maintenance solutions for a variety of advanced defense systems. Their focus includes equipment from well-known defense manufacturers such as Rheinmetall. with products including :

1. Rheinmetall Skyshield 35mm : This is a short-range air defense system designed to protect critical assets against aerial threats like drones, aircraft, and missiles. Regular maintenance would be essential to ensure the weapon system functions at peak performance.

2. Searanger 20mm : Likely a naval or close-defense weapon system, such as those used for ship protection or defense against smaller aerial threats. Maintenance here would likely involve ensuring the mechanical parts and ammunition handling systems are reliable.

3. Millennium 35mm : This is another air defense system (perhaps similar to Skyshield) that is designed for short-range protection. Again, routine checks, repairs, and updates would ensure it is ready to deploy when needed.

4. FieldGuard Radar : A radar system designed to detect and track potential threats, whether in the air or on the ground. Maintenance would likely involve software updates, calibration, and perhaps mechanical repairs to maintain accuracy and reliability.

Given the critical nature of defense equipment, preventive maintenance, calibration, and system upgrades would be a regular part of OCWSB Pratama's role in maintaining the readiness of these systems.
