Indodefence 2025: Indonesia Fields Indigenous SLT Anti-Tank Rocket to Enhance Ground Combat Readiness.

Unveiled at the Indo Defence 2025 exhibition, the SLT (Senjata Lawan Tank) anti-tank rocket system is the result of a strategic partnership between two Indonesian defense companies, PT Hariff Dipa Persada (Hariff Defense) and PT Dahana. This project represents a key development in Indonesia’s efforts to establish domestic production of light weaponry, aiming to meet both training and, eventually, operational requirements.

The cooperation was formalized through the signing of a memorandum of understanding (MoU) on June 12, 2025. The agreement is based on industrial complementarity. Hariff Defense is responsible for the launcher’s development, including electronic components, aerodynamics, and the rocket’s architecture. Dahana, a state-owned enterprise, supplies explosives, propellants, and thermal insulation materials. The end-user is identified as the Indonesian Army’s Infantry Weapons Center (Pusenif AD), indicating the intent to integrate the system within the national doctrinal framework.

The SLT is designed to disable enemy armored vehicles using rockets equipped with shaped-charge warheads, available in live or smoke variants. The system features a reusable launcher equipped with an integrated sight and a 0.6-inch OLED screen, which displays firing data derived from electronic sensors and rangefinders. The onboard software runs on a Linux platform and is programmed in C++ to manage ballistic computations and sighting functions.

The launcher weighs 3.345 kg (excluding the rocket), measures 1,002 mm in length, and uses an electric trigger. It supports controlled firing and can engage targets at ranges between 200 and 300 meters. It is also reloadable. Target range is determined through a combination of laser rangefinding and human visual estimation up to 1,000 meters.

The rocket itself is 541.13 mm long, with a caliber of 78.06 mm, and weighs 1.459 kg. It includes a passive propulsion unit, an ARM Cortex-M4 32-bit processor, and a suite of sensors including accelerometers, gyroscopes, and proximity detectors. The rear fins are fixed, while the guidance fins are active. Materials used for the nose cone, warhead, and propulsion system include composites, rubber, aluminum, graphene, and polystyrene. The warhead uses an A5AP-type explosive.

The sighting unit is equipped with a 12.3-megapixel camera and a laser rangefinder capable of identifying vehicle targets up to 1,000 meters and human targets up to 300 meters. The system is powered by a DC voltage between 7.2 and 8.4 V, with a power consumption of 0.3 amperes. The sight weighs 1.27 kg and measures 120 x 115 x 108 mm.

In terms of local manufacturing, the domestic content level (TKDN) is reported at 50% for the rocket and 41% for the launcher, reflecting ongoing efforts toward gradual industrial autonomy. The project extends beyond training applications: Hariff Defense and Dahana plan to develop future versions of the system as guided missiles and, eventually, as smart munitions intended for tactical deployment.

The SLT thus constitutes a practical initiative by Indonesia to equip its armed forces with a lightweight, locally developed anti-tank system adaptable to various engagement scenarios. If series production is launched, the system could be widely deployed within the Indonesian military and contribute to further industrialization in the country’s light missile sector.
