About the Alvis Stalwart

The FV620-series Stalwart (informally called a ‘Stolly’) was designed by Alvis and entered service with the British Army in 1966 as a general transport truck. It was one of the same line of 6×6 vehicles including the Alvis Saracen, Saladin, and Salamander. The high mobility and amphibious capabilities were designed to resupply army units in the field.

The hull is the vehicle chassis. The engine is situated under the load deck in the rear of the hull and the gearboxes, differentials and transfer boxes.

The load deck was open-topped with large drop down panels on either side. Waterproof seals ensured that these would not leak when in the water.

The three man cab has the driver’s position in the center and a seat for a passenger either side. The cab can only be entered through two roof hatches.

The Stalwart can carry 5 tons of materiel, or tow 10 tons. In the water it can be driven at about 7 knots by thrust water-jet propulsion units.
