Defense electronics prime ASELSAN has formally expanded its line of air-launched precision strike weapons with the unveiling of the TOLUN-L laser-guided small-diameter bomb (SDB).
Unveiled during SAHA 2026 on May 7, 2026, the 250 lb-class munition integrates a Semi-Active Laser (SAL) seeker onto the proven INS/GNSS-guided TOLUN baseline glide body. Designed to bridge the tactical gap between static bunker-busting/standoff strikes and high-speed dynamic land/maritime target interdiction, the TOLUN-L enables tactical air platforms and uncrewed combat aerial vehicles (UCAVs) to lock onto moving ground vehicles, fast attack craft, and fleeting targets illuminated by airborne or ground-based laser designators. The weapon is tailored for native multi-carriage integration across Türkiye’s next-generation uncrewed aviation inventory, including the Bayraktar AKINCI, Bayraktar KIZILELMA, TUSAŞ ANKA-III, and Bayraktar TB3.

💥 Standoff Engagement Range: Up to 27 nautical miles (~50 km) when released from high-altitude armed MALE/HALE UCAV platforms; >100 km standoff range when launched from high-speed fighter aircraft
💥 Launch Operational Envelope: Release Altitude: 0 to 40,000 ft ASL | Deployable diamond-back pop-out wings unfold post-release to maximize glide ratio and standoff clearance
Guidance, Seeker Architecture & Target Interdiction
🚀 Primary Mid-Course Guidance: Inertial Navigation System (INS) paired with Anti-Jamming / CRPA-equipped Global Navigation Satellite System (GNSS) receiver with waypoint programming
🚀 Terminal Target Homing: Nose-mounted Semi-Active Laser (SAL) seeker locking onto STANAG 3733-compliant laser spot designations
🚀 Target Engagement Profiles: High-precision strike against high-speed moving targets, mobile armored vehicles, naval surface targets, and hardened tactical assets
🚀 Warhead Configuration: Blast-fragmentation warhead (or specialized concrete-penetrating options) engineered for high kinetic impact energy with minimal collateral damage radius
TIMES OF DEFENCE ASSESSMENT
The introduction of the TOLUN-L laser-guided variant represents a major capability upgrade for the Turkish Armed Forces’ uncrewed strike architecture. While the baseline INS/GNSS-guided TOLUN excels at standoff counter-value or counter-force strikes against fixed coordinates (such as radar installations, air defense nodes, and command bunkers), engaging high-speed moving targets required continuous sensor updates that static GPS coordinates could not supply.
From an engineering and operational perspective, fitting a Semi-Active Laser (SAL) seeker onto a 250 lb glide body with pop-out wings transforms the TOLUN family into a dual-mode dynamic interdiction weapon—similar in combat role to the U.S. GBU-39B/B Laser SDB or GBU-53/B StormBreaker. When paired with high-altitude targeting pods (such as the ASELSAN ASELFLIR-500 or ASELFLIR-600), UCAVs like the AKINCI or ANKA-III can launch TOLUN-L from a standoff range of 50 km, laser-designate moving targets in real time, and saturate enemy convoys or littoral naval swarms. Furthermore, using quad-pack SADAK-4T smart racks allows a single aircraft to carry deep magazine payloads (up to 8–16 precision glide bombs per sortie), providing sustained close air support (CAS) without compromising stealth internal bay limits on platforms like the KIZILELMA or ANKA-III.
