TOLUN-L: ASELSAN’s Guided Bomb Built to Hit Even When GPS Is Jammed

On battlefields where satellite signals are the first thing the enemy kills, a smart bomb needs more than GPS to find its target. ASELSAN’s TOLUN-L answers with triple-layered guidance and a laser seeker, packaged as a ready-to-hang 250 lb-class munition that chases even moving targets through skies thick with electronic interference.

TOLUN-L is an all-up round (AUR) munition — one that arrives from the factory fully assembled, with no separate guidance kit to install — combining inertial navigation (INS), satellite navigation (GNSS) and a semi-active laser seeker head, married to a fragmentation warhead. It is the newest member of the expanding TOLUN family, which now spans multiple seeker variants, part of ASELSAN’s strategy of building a complete domestic air-launched munitions portfolio.

Three brains, one for each phase

TOLUN-L reaches its target on three successive guidance modes. En route it follows pre-planned waypoints using inertial and satellite navigation; in the terminal phase its laser seeker wakes to lock onto laser energy reflected off the target from an aircraft or ground party, striking stationary or moving targets with metre-level precision. Thanks to the seeker’s wide field of view, the weapon tolerates release errors and tracks evasive targets right up to impact.

Key specifications

Trained for the electronic-warfare environment

ASELSAN knows GPS spoofing — broadcasting fake signals to deceive a weapon about its position — has become a daily weapon in modern conflicts, so TOLUN-L ships with spoofing-resistant software and an optional CRPA anti-jam antenna that distinguishes genuine signals from fakes by their direction of arrival. And when every jamming method fails to mislead the munition, its laser seeker offers a terminal path that never relies on satellites at all.

Four weapons under one wing

TOLUN-L is designed for carriage on the SADAK-4T smart pneumatic quad rack, which hangs four munitions from a single hardpoint — multiplying the targets a single sortie can service while cutting sortie counts and operating costs. It can also be carried independently under-wing or in an internal weapons bay, opening the door to integration with next-generation stealth platforms, and it can engage single or multiple targets simultaneously in a single sortie, day or night.

Why it matters

In the smart-munitions race, the question is no longer “does it hit?” but “does it hit anyway?” — despite jamming, spoofing, darkness and target motion. By answering that question in layers, TOLUN-L shows that the Turkish defence industry designs its weapons for tomorrow’s wars rather than yesterday’s parades, and adds to the wings of Turkish jets and drones a munition that knows its way to the target even when the whole sky goes dark.
