In 1982 the Shark was successfully tested in Switzerland, fitted with a French Fives-Gail Babcock FL-12 turret armed with a 105 mm gun and a SOPTAC fire control system.

Late in 1983 one Shark prototype was fitted with the one-man turret of the Wildcat twin 30 mm SPAAG system and this was tested in Canada early in 1984.

[1] The hull of the MOWAG Shark is of all-welded steel construction which provides complete protection up to and including the Soviet 14.5 mm KPV armor-piercing round.

[citation needed] According to the manufacturer, a 155 mm HE projectile landing ten meters away from the vehicle will cause no damage.

A second crew member can be seated to the right of the driver, or the space can be used for special equipment such as an NBC pack or for additional ammunition stowage.

A wide range of armament installations can be fitted, up to and including an FL-12 turret with a 105 mm gun as also used on the Austrian Steyr-Daimler-Puck SK-105 Kürassier light tank/tank destroyer.
