Bandkanon 1 (officially 15,5 cm bandkanon 1, abbr. 15,5 cm bkan 1, lit. "15.5 cm (6.1 in) tracked cannon 1")^[​1] was a Swedish self-propelled artillery vehicle in use with the Swedish Army from 1967 to 2003 developed by Aktiebolaget Bofors. Its product name was Bofors Vagnkanon 155 mm L/50, abbr. VK 155 L/50, meaning "Tracked Automotive Gun 155 mm L/50" (terminological translation) or "Wagon Cannon 155 mm L/50" (literal translation).^[​2] Bkan 1 was one of the world's heaviest and most powerful (in terms of volume of fire) self-propelled artillery vehicles in use during its service.



It had a 155 mm autocannon with an exceptionally high rate of fire, being able to fire 14 shells in less than 45 seconds.^[​3] With one round already loaded in the gun beside the two seven-round clips in the magazine, the rate of fire rose to an official world record of 15 rounds in 45 seconds. The magazine could then be reloaded with a built-in hoist in about 2 minutes.

Each shell had a weight of 47 kg and a tactical range of 28 km.

Its chassis was based on a lengthened Stridsvagn 103 with one extra road wheel. The first variant, the Bkan 1A, used the same engine as the first Strv 103's and was thus somewhat under powered since that engine was designed to drive a 30-ton tank unlike the Bkan 1 which weighed over 50 tons. Despite this its mobility was more than adequate for its role as an artillery piece.
