The Ikv 91, or Infanterikanonvagn 91, was a high mobility tank destroyer that was developed to meet the operational requirements of the Swedish Army. It was designed and manufactured by Hägglund and Söner (now Hägglunds Vehicle AB) and employed common components with the Pbv 302 armoured personnel carrier series. The first prototypes of the Ikv 91 were completed in 1969 with production running from 1975 until 1978.

In layout, the Ikv 91 resembled a large light tank. The main armament consisted of a Bofors 90 mm L/54 rifled low pressure gun, firing HEAT and HE rounds, in a well sloped revolving turret. This gun had an elevation of +15 degrees and depression of -10. In addition, the Ikv91 was fitted with two 7.62 mm Browning machine guns; one in a coaxial mounting, and the second on a pintle attached to the commander's cupola. Two 71 mm Lyran flare launchers were mounted on the turret along with a set of smoke dischargers. The vehicle was equipped with a laser rangefinder and a computerised fire-control system for increased first-round hit probability. The rate of fire was 8 rounds per minute and 59 rounds of 90 mm ammunition were carried internally.

With wide tracks and a high weight to power ratio, the Ikv 91 offered exceptionally good off-road mobility, and the low ground pressure enabled it to operate over summer tundra and winter snow. The vehicle was fully amphibious with little preparation by the crew, and some models were equipped with propellers for increased speed in the water. The vehicle weighed 16.3 tonnes and had a crew of four. It is powered by a Volvo 12 liter, 330 hp, diesel engine. Maximum road speed was 65 km/h. The range on roads was about 500 km.
