Specs

Launch year 2025
MTOW 1588 kg
Payload 454 kg
Speed 56 km/h
Propulsion 999cc internal-combustion engine rated at 114 HP with automatic PVT (P/R/N/L/H) transmission, per the OEM product sheet; press describes it as gas-powered. A 100 Ah 24 V battery supports about 2 hours of engine-off idle (silent watch) and 1 kW of payload power via a NATO 24 V connector; the battery does not drive the wheels.
Comm Onboard passive sensors per OEM/press at launch; later press lists high-resolution stereo cameras, LiDAR, inertial measurement units, thermal imaging and GPS-denied localization. Sensor vendors are not disclosed.
Price notes No unit price published. The OEM sheet only claims payload carriage 'at up to two orders of magnitude less cost than current solutions'. The Marine Corps APFIT production award ($20M in June 2026 for 'more than a dozen' vehicles, raised to $24.5M in Oct 2026 for the 75th Ranger Regiment) bundles software and fielding and is reported as covering the newer MRZR-based IBEX rather than ULTRA, so no per-unit figure is derived from it.
