ADVENT (Network-Assisted Data Integrated Warfare Management System)

ADVENT (Network-Enabled Integrated Warfare Management System) is a domestic and national command and control and warfare management software developed by HAVELSAN in collaboration with the Command of the Turkish Naval Forces. Development of the system began in 2010 and it features a network-centric architecture that enables the integrated management of multiple naval, air, and land elements forming a task group around a common operational picture, rather than relying on a single platform. ADVENT is a second-generation solution built upon GENESiS, Türkiye's first national warfare management system, and was integrated onto TCG Kınalıada in September 2019, entering service with the Turkish Naval Forces inventory.

The first modern warfare management system of the Turkish Naval Forces was the STACOS SEWACO system, introduced alongside the Doğan-class fast attack craft starting in 1977. This was succeeded by the TACTICOS warfare management system, which was introduced with the Barbaros-class frigates and offered enhanced capabilities. In the mid-1990s, the K-5 Command and Control System, developed by the Research Center Command (ARMERKOM) for the Tepe-class frigates, marked the first step toward incorporating domestic resources alongside foreign systems.

GENESiS, or Ship Integrated Warfare Management System, was a project initiated within ARMERKOM to modernize the warfare management systems of former Oliver Hazard Perry-class (Gabya-class) frigates transferred from the United States Navy. Building on experience gained from the K-5 project, ARMERKOM began development of GENESiS in 1998 as Türkiye's first indigenous naval warfare management system. Starting in 2005, existing closed-architecture shipboard warfare management systems were replaced with the fully distributed and scalable modern GENESiS system, enhancing the vessels’ situational awareness, decision support, air defense, anti-submarine warfare, surface warfare, and electronic warfare capabilities. GENESiS has also been implemented on three MİLGEM Ada-class corvettes developed under the national corvette program and on two Bayraktar-class landing ship tanks.

As GENESiS became functionally unable to meet evolving operational requirements, new warfare domains, and non-combat mission needs, a requirement emerged for a next-generation warfare management system. In 2010, the Research Center Command and HAVELSAN initiated development of the Network-Enabled Integrated Warfare Management System (ADVENT). Following intensive development and testing conducted by Turkish Naval Forces personnel and HAVELSAN engineers, ADVENT SYS was successfully integrated onto TCG Kınalıada (F-514), the final vessel of the MİLGEM Ada-class corvette program, and entered service with the Turkish Naval Forces inventory in September 2019. Thus, a software infrastructure comprising millions of lines of code, developed entirely by Turkish engineers, entered service as the second-generation solution built upon Türkiye’s first national warfare management system project (GENESiS).

The ADVENT Warfare Management System is one of the tangible indicators of Türkiye’s acquisition of independent software-based command and control capabilities within its defense industry.^【1】 ADVENT, representing the second phase of Türkiye’s indigenous warfare management system development initiated with GENESiS, not only meets the needs of the Turkish Naval Forces but is also being exported to other countries. The planned export of the system to a NATO member country in 2026 constitutes a significant milestone in enhancing the system’s recognition within the NATO region.

ADVENT SYS is a fully domestic and indigenous warfare management system designed to meet the requirements of force-centric and network-enabled operations, rather than single-ship operations. It provides full operator access to integrated tactical data links (Link 11, Link 16, Link 22, SIMPLE, JREAP, and VMF), facilitates rapid and accurate decision-making through integrated decision support systems, and supports flexible integration of new weapons and sensors. Developed with a modular architecture compatible with multiple mission profiles and platform types, its scalable open design allows customization for surface, underwater, and air platforms as well as land-based facilities.

ADVENT stands out particularly due to its Network-Enabled Capability. Developed in accordance with a hierarchical structure featuring centralized control and distributed execution, this capability enhances operational effectiveness by enabling platforms to share their capabilities with other platforms. Key applications within this framework include:

• Common Engagement Capability: ADVENT provides a planning capability that enables coordinated use of the entire force’s air defense assets to respond to dynamic and rapidly evolving air defense environments. Weapons and sensor resources of platforms operating together are shared through this capability to execute coordinated mission plans across the task group.
• Task Force Oriented Services: Platform-specific services such as navigation plans, formations, and movement plans are planned and shared with consideration of the capabilities of other platforms operating in concert.
• Training Capabilities: The system provides advanced training opportunities both in virtual environments supported by simulators and in real environments using actual systems. These training exercises can be conducted on a single-platform basis or across multiple platforms connected via the network infrastructure.

ADVENT features a rule-based decision support capability that allows operators to define rules governing track behavior and to plan actions to be executed when tracks meeting those rules are detected. Once activated, the system automatically applies the defined rules and executes the specified actions.

ADVENT is designed as a platform-independent warfare management system. An integration approach has been adopted to support a common engagement infrastructure for new weapons and sensors, enabling compatibility with any platform. As a result, the system can be adapted to platforms ranging from small boats to large warships, from land-based command centers to unmanned systems. It is currently operational on more than thirty platforms across surface, underwater, and air operational environments.

Platforms on which ADVENT SYS is either in use or planned for integration include the LHD Anadolu, the Naval Replenishment and Communications Support Ship TCG Derya, the I-class frigate TCG İstanbul, and the TCG Ufuk test and training ship. Integration is also planned for modernized Burak-class corvettes and Barbaros-class frigates. Additionally, the system has been integrated onto the ULAQ armed unmanned surface vehicle, developed in collaboration with Ares Shipyard and MEKSAN Defense.

ADVENT has been exported to Pakistan, Indonesia, Ukraine, Qatar, Oman, Nigeria, Malaysia, and Chile. The system will also be integrated onto four MİLGEM-class corvettes being produced for the Pakistan Navy, onto the MİLGEM corvette being produced for Ukraine, and onto two offshore patrol vessels of the Indonesian Navy.^【2】

Integration efforts between the military vessel TCG Anadolu, noted for its performance in the Steadfast Dart 2026 exercise, and its embarked armed unmanned aerial vehicle, the Bayraktar TB3, using ADVENT SYS and the FleetStar Ship Data Distribution System, were completed prior to the exercise. As a result, TCG Anadolu achieved digital interoperability with the Bayraktar TB3, enabling data exchange between the vessel’s systems and the UAV.

In this integration, ADVENT SYS manages all onboard systems—including radar, sonar, weapons, and electronic warfare equipment—from a single central point, while the FleetStar Ship Data Distribution System provides the data distribution infrastructure necessary to support this architecture. Thanks to ADVENT SYS’s network-centric design, information obtained from the Bayraktar TB3 can be shared not only with TCG Anadolu but also with other vessels in the task group.

This capability is regarded as a milestone in the transition of TCG Anadolu to its UAV/UAS-integrated concept. A bidirectional data flow has been verified between the Bayraktar TB3 and ADVENT SYS, significantly increasing data access speed by directly transferring UAV imagery into the warfare management system.

HAVELSAN has for the first time exported the ADVENT Warfare Management System to a NATO member country as part of the sale of the CAm.ROMAN corvette to Romania. Under the export contract, ADVENT has been delivered alongside the vessel for use by the Romanian Naval Forces Command.

With this export, ADVENT has entered the inventory of a NATO ally for the first time, following previous exports to non-NATO countries. The version delivered to Romania is an adapted variant of the Turkish Navy’s configuration, tailored to Romania’s operational requirements. The system’s modular architecture enables the development of customized solutions for different customer profiles. HAVELSAN continues to enhance ADVENT with the “ADVENT AI” version incorporating artificial intelligence and is pursuing efforts to offer various versions of the system to new countries.

Alongside the delivery of the vessel to Romania, the export pathway has also been opened for other domestic systems, including the YELKOVAN Electronic Warfare System, developed in collaboration with TÜBİTAK and used by the Turkish Naval Forces, and the TARGAN 12.7 mm automated stabilized weapon system, developed with UNIROBOTICS.
