Alvis FV620 Stalwart is a high-mobility amphibious 6×6 logistics vehicle designed for land and water operations, tactical transport, and logistical support.
Specifications
- Frameless amphibious hull: Built with a fully welded, watertight steel hull and pontoon-shaped architecture designed to deliver complete buoyancy and water-crossing capabilities.
- Rolls-Royce multi-fuel / gasoline powerplant: Powered by a robust inline 8-cylinder Rolls-Royce engine mated to a multi-speed manual transmission and specialized transfer case driving all six wheels.
- Dual water-jet propulsion: Equipped with twin steerable water-jet units mounted at the rear, allowing smooth transitions from land movement to water navigation at speeds of approximately 6 knots.
- Heavy payload bed: Features an open cargo deck with fold-down side panels designed to carry up to 5 tons of military supplies, equipment, or specialized ordnance.
Features
- Amphibious logistics and supply: Engineered to cross rivers, flooded terrain, and coastal zones seamlessly, maintaining critical supply lines for front-line combat units without relying on standard bridges.
- Artillery support variants: Adapted into specialized configurations, such as the FV623, equipped with hydraulic cranes to handle ammunition resupply for artillery batteries directly in the field.
- Cross-country mobility: Utilizes a unique 6×6 multi-wheel steering and heavy-duty chassis design to navigate difficult terrain, mud, and unpaved deployment zones.
- Amphibious physics and handling: Introduces complex land-to-water transition mechanics, water-jet steering simulation, and heavy 6×6 truck driving dynamics into virtual environments.
- Logistical infrastructure: Complements tactical transport fleets, forward bases, and heavy equipment mod categories within open-world simulation scenarios.
