This is a conversion set to model the 90 mm-armed export version of Scorpion, based on the AFV Club kit.
For the export market Alvis fitted Scorpion with a Belgian-designed 90 mm Cockerill gun. Firing high efficiency ammunition, it offered performance very close to 105 mm guns fitted to heavier vehicles. The turret of the Scorpion 90 was designated the AC90 and was almost identical to that fitted to the basic vehicle.
The 90 mm gun had an elevation of +30° and a depression of -8°, almost the same as the basic Scorpion. The turret is equipped with fully stabilised day/night (thermal) gunner’s sight with laser rangefinder, and a ballistic computer for firing on the move and at moving targets. Scorpion 90 carried 34 main ammunition rounds (normal Scorpion carried 40 rounds of 76 mm ammunition).
In mid-1988, Venezuela placed an order with Alvis for the supply of an undisclosed number (believed to be 50) of Scorpion 90. The first vehicles were completed late in 1989 and deliveries were completed in 1992.
