FAP 2026 is a general purpose off-road lorry made by Serbian vehicle manufacturer Fabrika automobila Priboj (FAP). The six-wheel drive lorry is designed for transport of personnel, weapons and material up to 6 t (5.9 long tons; 6.6 short tons) of total weight, as for traction of weapons and trailer up to 7.2 t (7.1 long tons; 7.9 short tons) of weight for the needs of the Yugoslav People's Army.
Development
[edit]During 1965 the Department for Traffic of Federal Secretariat of People's Defense has formed work group with task to analyzes the unarmored vehicles of Yugoslav People's Army. The result of the work group was the study of non-combat vehicles and trailers in use with Yugoslav People's Army. The inferences of study were adopted by the Main Military Technical Council in 1966. The study has concluded that there are 129 different vehicle marks in 320 types in service. A decision was made to reduce number of different vehicle marks in service by development of five vehicle classes: 0,75 tons 4x4 off-road vehicle, 1,5 tons 4x4 off-road truck, 3 tons 6x6 off-road truck, 6 tons 6x6 off-road truck and 9 tons 8x8 heavy off-road truck.[1]
During the 1970s the plan for 1.5 t (1.5 long tons; 1.7 short tons) 4x4 and 3 t (3.0 long tons; 3.3 short tons) 6x6 off-road trucks was realized by TAM, while the 6x6 heavy truck was developed by the FAP. The first 6 t (5.9 long tons; 6.6 short tons) 6x6 military truck model developed by FAP was FAP 2220, mainly produced for transportation of the sections of PM M71 pontoon bridge and prototype series of M-77 Oganj self-propelled multiple rocket launcher. The new model, designated FAP 2026 BS/AV was developed during the late 1970s and introduced to service in 1978. It was based on the Mercedes-Benz NG with a OM 402 8-cylinder, 4-stroke, water cooled diesel engine, due to the fact that FAP has produced trucks under Mercedes-Benz licence.[2]
The FAP 2026 was mass-produced for the needs of the Yugoslav People's Army from 1978 until the 1994. Several small series were produced during the 1990s after the dissolution of Yugoslavia.
The FAP 2228 model was further development based on FAP 2026.

It offers an 8-ton pulling capacity with a 60-meter steel cable, enabling the truck to self-recover from obstacles or assist immobilized vehicles in rough terrain, such as mud, sand, or steep inclines. The winch is integrated into the front chassis frame for balanced weight distribution and durability, with controls accessible from the cab for safe, operator-monitored deployment.[21] Further enhancing towing and protection are additional mechanical fittings, including a rear pintle hitch rated for trailer loads up to 7.2 tons, wire-mesh guards around the headlights and taillights to prevent damage from branches or debris, and heavy-duty mud flaps to minimize spray and underbody fouling during operations on unpaved surfaces. Select engineering variants incorporate specialized attachments like folding bridge-laying ramps, which allow the truck to deploy temporary crossing structures over ditches or streams.[21] To streamline upkeep, the FAP 2026 incorporates a centralized lubrication system that distributes grease to key chassis fittings, such as pivot points and suspension bushings, via a single access point, reducing downtime and maintenance effort in remote deployments.[7]Electrical system
The FAP 2026 employs a 24 V electrical system to power its starting, lighting, and auxiliary functions, ensuring reliability in demanding off-road and military conditions. The system is supported by two 12 V batteries connected in series, offering a total capacity of 360 Ah for sustained operation. A waterproof 4.8 kW starter motor provides robust cranking power for the engine, capable of functioning in wet environments typical of tactical deployments.[23] Charging is handled by a 2.5 kW alternator with an integrated voltage regulator, which maintains stable output and prevents voltage fluctuations during vehicle operation. The alternator, mounted on the right side of the engine and driven by its rotation, supplies power to the batteries and electrical loads while incorporating waterproofing and radio frequency interference suppression for electromagnetic compatibility.[24][25] Electrical circuits are protected by dedicated fuses to isolate faults and prevent system-wide failures. The lighting array consists of sealed-beam headlights for primary illumination and blackout lights designed for concealed operations, minimizing visibility during nighttime maneuvers. The instrument panel includes electrically driven gauges for fuel level, engine coolant temperature, and oil pressure, providing critical operational data to the driver. Accessory wiring supports hydraulic controls for the winch and provisions for an optional radio, with grounding straps integrated to mitigate electromagnetic pulse effects and enhance overall system resilience in hostile electronic environments.[24]Operational use
Current operators
The FAP 2026 remains in active service primarily with the Serbian Armed Forces, functioning as a rugged 6x6 off-road truck for personnel and material transport, as well as a chassis for integrated weapon systems such as artillery and air defense platforms.[26] Modernization efforts since the 2010s have focused on upgrading the FAP 2026's chassis and powertrain for enhanced off-road performance and compatibility with digital systems, including its use in the upgraded PASARS short-range air defense system and the M-77 Oganj multiple rocket launcher. At the Partner 2025 defense exhibition in September 2025, Serbia showcased systems like the TSMB 203mm self-propelled mortar carrier mounted on the FAP 2026 chassis, highlighting its ongoing role.[27][28][26] The FAP Corporation in Priboj continues to support the Serbian Armed Forces' FAP 2026 fleet amid broader defense modernization initiatives.[8] Derived from Yugoslav-era designs, the FAP 2026 has seen adoption by several successor states, though Serbia maintains the most extensive active employment in military logistics.[29]Former operators
The FAP 2026 served as the primary logistics vehicle for the Yugoslav People's Army (JNA) from its introduction in 1978 until the JNA's dissolution in May 1992. Designed for off-road transport of personnel, weapons, and materials in harsh conditions, it supported Cold War-era military exercises and operational deployments across diverse terrains.[30] Following the breakup of the Socialist Federal Republic of Yugoslavia in 1991–1992, JNA assets including FAP 2026 trucks were redistributed to the armed forces of the successor states, such as Serbia and Montenegro (forming the initial core of the Yugoslav Army), Croatia, Slovenia, Bosnia and Herzegovina, and North Macedonia. This division occurred amid the conflicts of the Yugoslav Wars, with equipment often seized or negotiated during the transition from federal to national militaries.[31][32] In the Federal Republic of Yugoslavia during the 1990s, international sanctions severely restricted access to spare parts and maintenance, leading to the decommissioning and partial scrapping of aging military vehicles like the FAP 2026 to repurpose materials or due to operational obsolescence. By the late 1990s, the vehicle was being phased out in favor of newer models such as the FAP 2228 for ongoing logistics needs.[33]References
