Türkiye’s Aselsan ASAF 155 MOFA delivers inductive programmable fuze to NATO 155mm.

ASELSAN announced the ASAF 155 MOFA, an inductively programmable, multi-option fuze for JBMoU-compliant 155 mm howitzers, with proximity, point-detonating (super-quick and delay), and time modes.

On October 1, 2025, Aselsan presented the ASAF 155 MOFA, a new electronically programmable multi-option fuze for 155 mm artillery that aims to standardize effects across NATO-class systems while raising safety and reliability thresholds, as reported by Aselsan. Designed for JBMoU-compliant 155 mm howitzers and automatic loaders, the fuze adds flexible employment modes and environmental robustness to conventional tube artillery. Its proposition is timely as armies seek precise, scalable lethality without sacrificing crew safety or logistic simplicity. For industry and operators, the arrival of a fully inductively settable fuze in this category signals a maturing ecosystem for programmable effects at battalion and brigade level.

ASAF 155 MOFA is an inductively programmable, electronic multi-option artillery fuze that can be set via a fuze setter without mechanical coupling. It is compatible with all 155 mm shells and with 155 mm/52-calibre howitzers using automatic loading systems, and is fully compliant with JBMoU artillery interfaces. The fuze offers four operating modes, Proximity, Point-Detonating Super Quick, Point-Detonating Delay, and Time-Programmable, plus two selectable heights of burst at approximately 6 m and 12 m. It is engineered to remain safe under heavy rain, integrates a well-proven safety-and-arming device for storage, transport, and operation, and features high resistance to jamming. The unit follows STANAG 2916 dimensions, measures up to 151.6 mm in height with a 2-12UN-1A thread, weighs about 770 g, incorporates a ≥100 m muzzle-safety distance, requires about 1500 G and 3500 RPM to arm, and is specified for a 15-year shelf life.

Compared with legacy point-detonating (PD) or pure time-fuze solutions, the ASAF 155 MOFA’s inductive programming reduces manual handling and mechanical wear points, lowering set-time and mis-set risk while improving repeatability across gun lines. The dual-height proximity function provides more consistent airburst patterns over varied terrain and target postures than single-height proximity or strictly time-set bursts, enhancing lethality against dismounted infantry and light materiel. Its PD-Delay mode, described as having a unique penetration capability, expands utility against light cover and field fortifications where instantaneous PD can be sub-optimal. In contrast to older clip-on or mechanically keyed setters, the contactless inductive approach aligns with modern automatic loaders and digital fire-control workflows, improving throughput and compatibility across JBMoU howitzers. Anti-jamming hardening and “safe under heavy rain” behavior add environmental resilience that many fielded multi-option fuzes only partially address.

Strategically, a JBMoU-compliant, inductively settable fuze consolidates 155 mm effects into a single, widely interoperable item, simplifying stockpiles and easing multinational operations. At the military level, batteries gain faster transitions between proximity airburst for area suppression, super-quick PD for surface targets, delay for defilade or light structures, and time-programmable effects for obstacle reduction or illumination-adjacent tasks, all while keeping muzzle-safety margins and arming conditions within conservative thresholds. For geostrategic users operating across varied climates and coalition architectures, the combination of high reliability, environmental robustness, and long shelf life supports dispersed logistics, prepositioned stocks, and rapid deployment models without bespoke fuze families per mission set.

ASAF 155 MOFA positions itself as a practical uplift to 155 mm artillery, marrying inductive programming, multiple effect modes, and robust safety into a fuze engineered for today’s JBMoU fleets and tomorrow’s automated gun lines. By compressing several mission profiles into a single, contactlessly set device, while preserving environmental resilience and long service life, it offers artillery units a credible path to faster, safer, and more adaptable fires in coalition operations.
