Türkiye's ASELSAN Declares TOLUN-P Bunker-Busting Munition Mission-Ready After Successful AKINCI Test

ANKARA, Türkiye — Turkish defense company ASELSAN has announced that its TOLUN-P bunker-penetrating guided munition is ready for operational use following a successful firing test from the Bayraktar AKINCI unmanned combat aerial vehicle (UCAV). The latest test confirmed the weapon's ability to carry out precision strikes against hardened military targets, including underground bunkers, fortified command centers, armored hangars, and reinforced structures.

During the test, the Bayraktar AKINCI released the TOLUN-P, which achieved a direct hit on its designated target. ASELSAN also released footage of the test, stating that the bunker-penetrating munition has now reached mission-ready status after completing its development and evaluation process.

Designed for Hardened Targets

The TOLUN-P is part of ASELSAN's 250-pound class of compact precision-guided munitions. According to the company, the weapon has a total weight of 136 kilograms and is equipped with a 105-kilogram penetrator warhead developed to defeat hardened and reinforced targets.

One of the weapon's key features is its hardened nose design, which, together with its kinetic energy, enables it to penetrate up to one meter of reinforced concrete before detonation. Instead of exploding immediately after impact, the munition uses an electronically programmable fuze that can be set by the pilot before launch. The delayed detonation allows the warhead to explode inside the target structure, increasing its effectiveness against protected facilities.

Guidance and Anti-Jamming Features

The TOLUN-P combines Global Navigation Satellite System (GNSS) guidance with an Inertial Navigation System (INS) to maintain accuracy during flight. ASELSAN says the munition is also equipped with a four-channel Controlled Reception Pattern Antenna (CRPA) and built-in anti-spoofing software designed to help the weapon continue toward its target even if satellite navigation signals are jammed or interfered with.

According to official specifications, the munition has a circular error probable (CEP) of less than 10 meters. ASELSAN also states that the weapon can achieve a maximum range of approximately 55 nautical miles (about 102 kilometers) when released from a high-altitude fighter aircraft, while its range is lower when launched from unmanned aerial platforms.

SADAK-4T Increases Weapon Capacity

The TOLUN-P is designed to operate with ASELSAN's SADAK-4T smart pneumatic quad rack, which enables a single weapons pylon to carry four TOLUN munitions simultaneously.

An aircraft equipped with two SADAK-4T racks can carry up to eight TOLUN munitions during a single mission. The system also allows pilots to program the electronic fuzes before release and engage multiple targets in a single sortie.

For aircraft that do not use the quad-rack configuration, ASELSAN has also developed the TOLUN-SI, a version with a different mounting interface for single-carriage integration.

Development and Testing

Development of the TOLUN family began in 2020 to provide Türkiye with a domestically developed precision-guided weapon capable of striking hardened targets. The system was publicly introduced during the IDEF 2021 defense exhibition together with the SADAK-4T rack.

Testing started in 2022 with aerodynamic and structural evaluations before expanding to flight-release trials in 2023. Integration was extended to unmanned platforms, including the Bayraktar TB2 and Bayraktar AKINCI.

A major live-fire demonstration took place in December 2025 at a test range in Konya, where a TOLUN munition released from an AKINCI penetrated reinforced concrete and destroyed a UH-1 helicopter positioned beneath it.

Later in 2025, ASELSAN also demonstrated a longer-range version of the weapon, successfully striking a target located more than 100 kilometers away after being launched from an F-16 using the SADAK-4T rack.

Integration with KIZILELMA

ASELSAN has continued integrating the TOLUN-P with additional Turkish air platforms. The weapon has been tested on Baykar's KIZILELMA unmanned combat aircraft, including releases from its internal weapons bay during flight testing.

According to ASELSAN, KIZILELMA can carry up to eight TOLUN-P munitions internally using two SADAK-4T racks. Internal carriage enables the aircraft to carry weapons inside the fuselage rather than on external pylons, a configuration used during testing with the platform.

Variants of the TOLUN Family

In addition to the bunker-penetrating TOLUN-P, ASELSAN has developed several other variants for different operational requirements. These include the TOLUN-F fragmentation variant, TOLUN-L with a laser seeker, TOLUN-IIR equipped with an imaging infrared seeker, and additional configurations designed for different mission profiles.

According to ASELSAN, the penetrator warhead was designed by TÜBİTAK SAGE, while the remainder of the weapon system was developed by ASELSAN.

Export Deliveries

ASELSAN has confirmed that the first export deliveries of TOLUN munitions and SADAK-4T quad racks were completed in 2025. The systems were supplied to customers in the Middle East, Africa, and Asia, although the company has not disclosed the names of the recipient countries.

The declaration of mission-ready status following the latest AKINCI firing test marks another step in the operational deployment of the TOLUN family across both manned and unmanned Turkish air platforms.
