Stalwart Mk 2 (FV622, 623, 624)

The Mk 2 is the Stalwart most people have seen, in British service from the mid-1960s until 1993, swimming on vectored water jets at six to nine knots.

Procedural FV622 cargo representation, with centre driving position, low tied canvas, internal winch outlet and water jets. The crane-equipped FV623/FV624 and rescue examples were checked but their specialist equipment is not fitted. A reusable cargo base and named Mk 2 share the hull. Some source dates refer to 1965 manufacture versus 1966 service entry. The preserved Italy operating-country value appears to describe Mk 1 PV6, not Mk 2; country cells have not been silently rewritten.

Performance provenance: 64 km/h, approximately 164 kW and 8,636 kg empty are researched values. Top speed, power and mass fall outside the fleet suggested range because this is a heavy amphibious load carrier, not a light utility. Torque 178 Nm remains the CLI-derived default pending a verified source. Grip .84 and drag CdA 3.5 retain code-derived handling defaults; steering .85 reflects the indirect heavy six-wheel chassis, acceleration 1 is unchanged. Wheelbase 3.048 m and .56 m tyre radius are proportion/family geometry inputs, not newly verified factory measurements. Unarmed, unarmoured, no smoke. Amphibious role uses the existing water-hazard resistance and winch perks; it does not introduce a new swimming simulation.
