''Infanterikanonvagn'' ({{literal|infantry cannon wagon 91}}) is the Swedish post 1940s term for [[assault gun]], replacing the short-lived 1940s term ''stormartillerivagn'' ({{literal|assaullt artillery wagon}}) with the introduction of the [[Ikv 72]] in 1953. |

The main armament consisted of a [[Bofors]] KV90S73 90 mm L/54 rifled low pressure gun, firing [[High explosive anti-tank|HEAT]] and HE rounds. A sloped revolving turret gave protection against projectiles up to 25 mm in calibre. The main gun had an elevation of +15° and depression of −10°. The barrel was equipped with a fume extractor. Additional armament of the Ikv 91 included 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 mortar|Lyran]] flare mortars were mounted on the turret along with a set of smoke dischargers (usually 12). |

The vehicle was equipped with a [[laser rangefinder]], [[night vision]] (goggles) and a computerised fire-control system for increased first-round hit probability. The Ikv 91 fired at a rate of 8 rounds per minute and 59 rounds of 90 mm ammunition were carried internally. The vehicle was also capable of firing while in water, with the water absorbing most of the recoil. The turret itself has a small hatch that can be opened by the loader to eject used cartridge cases to prevent clutter in the vehicle. |

With wide tracks and a high [[power-to-weight ratio]], the Ikv 91 offered exceptionally good off-road mobility. The low [[ground pressure]] enabled the Ikv 91 to operate through summer [[taiga]] and winter snow. The vehicle was fully amphibious with little preparation by the crew. Screens would be erected to stop water from entering the engine and the cabin compartment with a vane to protect from oncoming waves. The vehicle weighed 16.3 tonnes and had a crew of four. It was powered by a Volvo 12 liter, 330 hp, diesel engine. The maximum road speed was {{convert|65|km/h|mph}} and the range on roads was about {{convert|500|km|mi}}. |

The Ikv 91 was retired from the Swedish army in the late 1990s – early 2000s due to budget cuts among others and was partly replaced by the [[Strf 90]] combat vehicles and [[Leopard 2]] tanks. When in active duty, the Ikv 91 was assigned to the Swedish infantry brigades, which had one company of 12 vehicles each. The 10th Mechanized Brigade had two companies in the 1980s. In the late 1980s and early 1990s, the 10th Mechanised Brigade had its Ikv 91 replaced with Centurion tanks and in 2000, all Swedish infantry brigades were disbanded. Plans were made to replace its 90 mm gun with a 105 mm gun or even a TOW missile launcher. This was however not followed through in Swedish interests as the role of the Ikv 91 could be filled by new [[Strv 122]] main battle tanks and [[Strf 90]] infantry fighting vehicles.<ref name=" |

The Infanterikanonvagn 91 (Ikv 91), lit. 'infantry cannon wagon 91', was a high mobility assault gun that was developed to meet the operational requirements of the Swedish Army. It was designed and manufactured by Hägglund & 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.[2] The total numbers manufactured were 212.
Designation
Infanterikanonvagn (lit. 'infantry cannon wagon 91') is the Swedish post 1940s term for assault gun, replacing the short-lived 1940s term stormartillerivagn (lit. 'assaullt artillery wagon') with the introduction of the Ikv 72 in 1953.
The number 91 in the name means that it was the first assault gun in the Swedish armed forces to feature a cannon in the 9 cm caliber category (91 = 9-1: 9 cm gun, 1st vehicle in category).
Design
The layout of the Ikv 91 is similar to a large light tank. The Ikv 91 is divided into three main compartments, the driver's station in the forward left hull, the fighting compartment located in the vehicle's midsection, and an engine compartment in the rear hull.
