At the IndoDefence 2025 exhibition, the Indonesian Armed Forces present a new observation drone designed to support field artillery operations. Developed to enhance long-range targeting and fire correction capabilities, the system is based on an autonomous platform called PTTA II (Pesawat Terbang Tanpa Awak Tahap II), a second-generation tactical unmanned aerial vehicle. This initiative reflects ongoing efforts by the Indonesian Army’s Field Artillery Command (Pussenarmed) to modernize target designation tools and indirect fire coordination.Follow Army Recognition on Google News at this link

The PTTA II system is built on a drone airframe powered by a hybrid propulsion unit combining electric and combustion engines. It offers a flight endurance of 90 minutes and a minimum operational range of 10 km. It cruises at speeds between 95 and 100 km/h with a flight ceiling of 400 meters. The drone features an automated navigation system with obstacle avoidance, managed by algorithms incorporating artificial intelligence for object recognition. Its primary observation equipment is a gyrostabilized camera with a 30x optical zoom and target lock function. A telemetry module transmits data in real time to the command and analysis station.
The ground control unit, mounted in a dedicated vehicle, integrates several management interfaces. One interface supports real-time video monitoring, automated impact trajectory analysis, and fire correction identification. Another software module enables mission planning, UAV tracking, waypoint editing, and cartographic analysis. These systems are designed to supply correction data to artillery batteries, thereby improving fire effectiveness.
The complete system also includes a 5.4-meter telescopic antenna, an autonomous power unit with backup batteries, vehicle stabilizers, and long-range communication equipment to maintain connection with command echelons.
The PTTA II’s development aligns with the Indonesian military’s objective of acquiring domestically developed target acquisition systems adapted to the regional operational environment. The project, led by Pussenarmed, illustrates the command’s ability to internalize the development of complex tactical systems and manage the entire design process. At this stage, the system’s proliferation remains limited to demonstrations and trials, with no official announcement regarding serial production or export to other units or international partners.
