The Bandkanon 1 (bkan 1) was a Swedish self-propelled artillery vehicle in use with the Swedish Army from 1967 to 2003. Bkan 1 was one of the world's heaviest self-propelled artillery vehicles in use during its service and since the engines were dimensioned for the lighter S-tank the bkan was somewhat underpowered. Despite this it had very good mobility.

It had an exceptionally high rate of fire, being able to fire 14 shells in 45 seconds.[1] With one round already loaded in the gun beside the two seven-round clips in the magazine, the rate of fire rose to 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.

Use[edit]

The plan was to produce about 70 vehicles, but due to cuts in defence budget only 26 bandkanon 1s were manufactured.[1] They were used as divisional artillery in Norrland, used by Boden artillery regiment and later Norrbottens regiment. They were organized in two battalions of 12 vehicles each until the late 1980s and after that, three battalions of 8 vehicles each until the bandkanon 1 was discontinued in 2003.

History[edit]

When the KRV tank project was canceled, the chassis was developed by AB Landsverk under the designation artillerikanonvagn 151 (akv 151). As the concept seemed promising, the self-propelled gun was re-designed by Landsverk under supervision of Kungliga Arméförvaltningen to use the same drive train as the S-tank and a main gun constructed by AB Bofors. Bandkanon 1 appeared in two versions, the original version was bandkanon 1 (later designated bandkanon 1A). After modification done to the vehicle during the 1980s, the new version was designated bandkanon 1C. The main difference was the introduction of a drive train more similar to the one introduced on the new "C" version of stridsvagn 103, other modifications were the removal of the built-in ammunition crane and the introduction of the POS 2 system for navigation, positioning and directing.
