FNSS unveils U-MAV unmanned amphibious vehicle to protect Türkiye’s assault force during beach landings.

Turkish defense manufacturer FNSS officially unveiled the U-MAV, also designated İ-ZAHA, during the Teknofest Mavi Vatan 2026 event at the Gölcük Naval Shipyard Command in Kocaeli. The 8-ton, 4×4 unmanned amphibious platform is engineered to serve as an advanced first-echelon element operating ahead of manned MAV/ZAHA assault forces during high-threat beachhead landings. By shifting critical breach, reconnaissance, counter-drone, electronic warfare, and direct-fire roles to an autonomous platform, the system mitigates direct risk to personnel confronting hostile anti-tank guided missiles and minefields.

Powered by a 300 hp engine yielding a 37.5 hp/tonne power-to-weight ratio, the U-MAV reaches 70 km/h on land and 7 knots in water to match the transit speed of manned MAV units. Built around a common 4×4 chassis supporting ten interchangeable mission modules, the platform incorporates local AI-driven target processing, structural damage sensors, a 3 km direct datalink, and UAV relay capabilities.

On August 20, 2026, the Turkish company FNSS unveiled the U-MAV, also known as İ-ZAHA, at Teknofest Mavi Vatan 2026 at Gölcük Naval Shipyard Command in Kocaeli. This 8-ton unmanned 4×4 assault vehicle is specifically intended to operate ahead of the Turkish Naval Forces' manned MAV/ZAHA force during contested amphibious landings. The U-MAV moves reconnaissance, mine clearance, combat engineering, electronic warfare, deception, counter-UAS, route-marking, and fire-support missions into a new unmanned first echelon, therefore limiting personnel risk when entering a minefield or ATGM-covered beach. The İ-ZAHA uses a 300 hp engine, giving it 37.5 hp/tonne, and reaches 70 km/h on roads and 7 knots in water, which exactly matches the speed of the larger MAV, allowing U-MAVs to move ahead of the manned force without imposing a lower nominal transit speed.

Ten mission configurations can be installed on the common chassis, with a module exchange taking approximately 40 minutes in field conditions. Control can be remote, autonomous, or hybrid; the U-MAV's direct line-of-sight communications reach 3 km, and a UAV relay can further extend the link when operators remain aboard a ship farther offshore. No customer, procurement quantity, unit price, or production schedule had been announced for the U-MAV at the time of its unveiling. The military problem behind the U-MAV is concentrated in a relatively short but potentially decisive portion of an amphibious assault: the period after landing vehicles have entered effective defensive range but before enough combat power has crossed the shoreline to maneuver inland.

A prepared defender can now place mines and fixed obstacles in the surf zone, on the beach and around exits, then cover those obstacles with machine guns and anti-tank guided missiles. An obstacle that stops the lead vehicle, a suspected minefield that forces a column to slow, or a blocked beach exit can compress the assault into predictable routes and give defenders more time to engage vehicles that cannot yet disperse. The problem is compounded because amphibious vehicles have to balance buoyancy, armor, payload, and water mobility, preventing them from simply adopting the protection levels of the heaviest land combat vehicles. The U-MAV could change who performs the initial reconnaissance and breach.

Reconnaissance variants can search for firing positions and obstacles, mine-detection vehicles can identify contaminated lanes, engineering variants can conduct breaching, navigation vehicles can mark cleared approaches, and fire-support vehicles can attack positions threatening the breach. Electronic warfare and deception U-MAVs add another layer by attempting to disrupt or complicate the defender's sensing and targeting process. Several U-MAVs/İ-ZAHAs can therefore divide a task sequence that would otherwise expose manned reconnaissance, engineering and assault vehicles during the opening minutes of the landing. The concept separates "first vehicle ashore" from "first Marines ashore," without eliminating the requirement for artillery, air support, loitering munitions or other fires capable of suppressing defenders while the breach is created. 

At 8 tonnes, the U-MAV/İ-ZAHA occupies a substantially different weight category from the MAV/ZAHA, as it concentrates that mass on propulsion, amphibious mobility, and mission payload rather than an embarked infantry compartment. Its 300 hp powerpack produces 37.5 hp/tonne, 87.5% higher than the MAV's 20 hp/tonne ratio. The chassis is a 4×4 with independent suspension and selectable tire options, whereas the MAV is tracked and uses torsion bar suspension. Water propulsion and the amphibious hull permit continuous ship-to-shore movement followed by land maneuver; 7 knots in water and 70 km/h after landing, like the MAV. The common maximum speeds are particularly relevant for manned-unmanned teaming because a breaching vehicle limited to 4 or 5 knots would either have to depart significantly earlier or force the personnel-carrying echelon to reduce speed during the approach.

The U-MAV also incorporates measures intended to reduce visual, thermal, and acoustic signatures, useful for a vehicle expected to operate forward of the main force. Its payload volume can instead accommodate weapons, drones, engineering equipment, electronic warfare systems, logistics loads, or casualties. Its lower mass also expands deployment options: the vehicle can be transported by road, rail, and sea and is compatible with CH-47F Chinook and Mi-26 helicopters as well as C-130 Hercules, A400M, C-17 Globemaster, C-5 Galaxy, An-124, and Il-76 transport aircraft. Wet sand, loose gravel, soft soil, gradients, ditches, and destroyed obstacles can still immobilize a wheeled vehicle, making pre-assault hydrographic and terrain reconnaissance relevant even when the lead element is unmanned. The ten configurations determine what a U-MAV formation could actually contribute to a landing.

They are named Fire Support, Mine Clearance, Combat Engineering, Electronic Warfare, Reconnaissance, Deception, Counter-Drone, Navigation and Obstacle Marking, Logistics Support, and Casualty Evacuation, all using a common sustainment base. Fire support options are themselves divided between different weapons. The Sancak remote-controlled weapon station (RCWS) can accept 7.62 mm and 12.7 mm machine guns, a 40 mm automatic grenade launcher, or a 30×113 mm weapon, while the UKTK launcher can carry Omtas or Kornet anti-tank guided missiles (ATGMs). A separate configuration carries loitering munitions, allowing the attack of targets beyond the İ-ZAHA's immediate direct-fire envelope. Reconnaissance vehicles can carry two Class 1 multirotor UAVs, allowing sensors to be pushed beyond the vehicle and potentially over obstacles, beach exits, or terrain masking the defender.

The counter-UAS configuration combines the Sancak with additional EO/IR sensors and jammers, providing both detection and hard-kill or electronic options against small unmanned aircraft. Engineering configurations include mine detection and mine breaching with a single-line charge, while another configuration provides broader combat engineering functions. This means an assault commander cannot obtain all ten capabilities by assigning one U-MAV to the lead. A realistic first echelon would require several vehicles with a configuration mix selected before launch, because the approximately 40-minute module-change time is suitable for re-tasking between missions or assault phases, not for changing from mine clearance to fire support while under direct fire. The common chassis also offers a fleet management advantage: the proportion assigned to reconnaissance, engineering, EW or fire support can be changed without procuring ten unrelated amphibious vehicle families. The manned side of this force is already considerably more mature.

Türkiye had received 27 FNSS MAVs and ordered another 27 in May 2026, potentially bringing the force to 54 vehicles once the second batch is delivered. The existing vehicles are intended to move personnel from amphibious ships such as the TCG Anadolu to the beach, while U-MAVs take over selected tasks ahead of them. The MAV measures 8.3 m long, 3.3 m wide, and 3.8 m high and has a crew/personnel capacity of 21, including the commander, driver, and gunner. Its 20 hp/tonne power-to-weight ratio is substantially lower than the U-MAV's 37.5 hp/tonne, but its mission includes carrying and protecting personnel rather than maximizing payload flexibility on an unmanned chassis. The MAV uses a diesel engine, a fully automatic transmission, and a torsion bar suspension and can negotiate a 60% gradient, 40% side slope, 0.9 m vertical obstacle, and 2 m trench.

The ten variants allow a military force to use the same U-MAV for different missions, including fighting, reconnaissance, mine clearing, engineering, electronic warfare, counter-drone operations, route marking, logistics and casualty evacuation. (Picture source: FNSS)

Its Çaka remote-controlled turret combines a 40 mm automatic grenade launcher with a 12.7 mm machine gun, provides continuous 360° traverse, and has an elevation range from -7° to +45°. The vehicle also carries day/night sights, 360° situational awareness, driver vision, battlefield management and navigation systems, VHF/UHF radios, and an internal crew communications system. Its ballistic and mine-protection levels remain classified, but survivability equipment includes eight smoke grenade dischargers, an integrated smoke generator, automatic fire suppression, CBRN protection, and self-righting capability. The U-MAV therefore reallocates the highest-exposure tasks away from a larger vehicle carrying people, while matching the MAV's water and road speeds to operate within the same movement. The 3 km direct communications range is one of the clearest constraints on that concept because amphibious ships do not necessarily operate within 3 km of a defended beach.

The U-MAV therefore combines an encrypted mesh network with GNSS/INS navigation, an IFF module, and UAV relay rather than relying on a single continuous radio connection between one operator and one vehicle. The inertial navigation unit maintains a position estimate when GNSS signals are unavailable, jammed, or degraded, which is important for a vehicle expected to navigate through marked lanes and obstacle fields where positional errors of even tens of meters can place it outside a cleared route. If the datalink is interrupted, the U-MAV initially enters a safe-hold state. It can subsequently return along a pre-programmed route or continue the assigned navigation task, depending on how that UGV has been configured before the mission.

This creates a different command problem for each variant: allowing a reconnaissance vehicle to continue a pre-planned route after losing contact is fundamentally different from allowing an armed fire support vehicle or an engineering vehicle carrying a line charge to continue its mission without updated human input. The mesh network also becomes more useful as the number of U-MAVs increases, as those vehicles can form part of the communications architecture instead of requiring an independent uninterrupted link to the ship. Drone relay extends that network beyond the 3 km line-of-sight limit, and a Bayraktar TB3 operating from TCG Anadolu could potentially combine communications relay with ISTAR functions for the amphibious force. The onboard mission computer addresses the related bandwidth problem by processing imagery locally rather than requiring the operator to receive every camera frame before detecting a threat.

Camera feeds are analyzed aboard the U-MAV, with the radio network able to transmit detection metadata instead of continuously sending full-motion video. Detected objects can be assigned a type, status, and threat score, displayed through color-coded overlays, tracked and stored with timestamps, while prioritized detections can be passed to the operator for engagement decisions. The practical effect is to reduce both bandwidth consumption and the operator's requirement to manually scan several video feeds if multiple U-MAVs are operating simultaneously. New target categories and engagement rules can also be inserted into the processing chain in the field without changing the camera installation. Separately, the U-MAV is the first unmanned vehicle integrating Nurol Teknoloji's Armor Integrity structural monitoring system into its digital architecture.

The system compensates for the absence of crew members who could otherwise assess a hit by sound, vibration, visual inspection, or changes in vehicle behavior. Sensors identify impact location, direction, and severity, estimate the remaining structural capacity of the affected area, and track damage accumulation. The operator can use that information to decide whether to continue, seek cover, reposition so a weakened area faces away from the threat, or assign the UGV a passive role. Damage records remain stored locally during communications loss and are transmitted after reconnection, providing a quantifiable vehicle health input for an operator who may be several kilometers away. The principal operational effect of the U-MAV is consequently to alter the composition and sequencing of Türkiye's amphibious first wave rather than make a defended landing intrinsically easy.

A force could launch reconnaissance U-MAVs and their Class 1 drones to locate obstacles and firing positions, send mine-detection and engineering variants toward selected lanes, employ line charges to breach obstacles, use navigation vehicles to mark those lanes, place EW vehicles nearby to interfere with hostile sensors and communications, and position Sancak-, UKTK-, or loitering-munition-equipped UGVs to suppress threats encountered during the breach. Only after that process begins would MAVs carrying Marines have to cross the same waterline and beach. The potential personnel risk reduction is therefore concentrated precisely where an amphibious assault is most canalized, but vehicle losses could remain operationally important.

A destroyed U-MAV can obstruct a cleared lane, loss of a specialized configuration removes a capability that another module cannot instantly replace, and a small fleet of less than ten cannot logically maintain simultaneous reconnaissance, breaching, EW, counter-UAS, fire support, route-marking, logistics and CASEVAC coverage. The 40-minute module-change time also means the configuration mix has to be planned against the expected defensive problem, while the 3 km direct communications limit makes drone relay and autonomous lost-link behavior necessary once the launch point moves farther offshore. The U-MAV should also not be treated as a substitute for suppression by artillery, naval fires, aircraft, or loitering munitions against intact ATGM and indirect-fire positions.

Its more specific contribution is to allow Türkiye to put machines carrying specialized sensors, breaching equipment, and weapons into the most exposed part of the assault before committing the personnel-carrying MAV force. With 27 MAVs already delivered and another 27 ordered in May 2026, the U-MAV therefore points toward a force structure in which unmanned vehicles conduct the initial reconnaissance, breach, and selected combat support functions, while the 54-vehicle manned MAV fleet remains responsible for moving Marines ashore and converting an opened landing corridor into a secured beachhead.
