The Bangladesh Army has begun a formal evaluation of the Turkish-made RDS40 Automatic Grenade Launcher (AGL) produced by Repkon Defence Technologies, alongside its associated programmable airburst munitions. This represents a significant step in the Army’s broader drive to modernise infantry fire-support systems and counter emerging battlefield threats, including drone swarms and entrenched adversaries.
Documentation circulated through the Directorate General Defence Purchase confirms that the first phase of trials has already taken place at the School of Infantry & Tactics (SI&T). The weapon will now advance to divisional-level testing, where its performance will be assessed across a wider range of operational environments and mission profiles.
The RDS40 is a lightweight, digitally compatible automatic grenade launcher designed to integrate modern fire-control systems and support advanced ammunition technologies. Bangladesh’s interest in the platform is notable given that the Army has long standardised the STK 40mm Automatic Grenade Launcher Mk2 from Singapore as its primary heavy fire-support weapon at the platoon level. The Mk2 variant remains highly regarded for its reliability, durable construction and proven effectiveness across both domestic duties and peacekeeping deployments. Nevertheless, the growing need for airburst capability and counter-drone solutions has prompted the Army to explore more advanced support weapons.
At the centre of this evaluation is the RDS40’s ability to employ programmable airburst grenades. These munitions can be electronically set to detonate mid-air at precise distances, enabling troops to neutralise enemies positioned behind cover, inside fortifications or concealed within complex urban terrain. Airburst fragmentation provides a decisive advantage in settings where line-of-sight engagements are difficult or impossible. It also offers a credible response to the proliferation of small drones, which increasingly present reconnaissance and attack threats on modern battlefields.
Bangladesh’s decision to examine programmable munitions reflects a shift towards more technologically sophisticated infantry capabilities. As operational environments become more unpredictable and adversaries employ a variety of concealment and drone-based tactics, airburst-enabled weapons provide soldiers with the necessary versatility and accuracy to respond effectively. Should the RDS40 perform favourably during divisional trials, it could be inducted alongside the STK Mk2, creating a layered support-weapon ecosystem that balances proven reliability with next-generation capability.
The Army is currently reviewing technical documentation, performance data and manufacturer certifications as part of its assessment process. Final decisions on procurement will be made after field trials conclude and operational suitability is confirmed.
The evaluation of the RDS40 marks a significant moment in the evolution of Bangladesh’s infantry firepower, signalling a commitment to modern, network-enabled weapons capable of meeting the demands of twenty-first-century conflict.
