Bandkanon 1 (bkan 1) was a Swedish self-propelled artillery vehicle in use with the Swedish Army from 1967 to 2003. It was developed by Bofors under the designation artillerikanonvagn 151 (akv 151) and the chassis was based on the never adopted KRV tank. When the KRV project was canceled the chassis of the self-propelled gun was re-designed to use the same drive train as the S-tank. 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. With one round already loaded in the gun beside the two seven-round magazines, the rate of fire rose to 15 rounds in 45 seconds. Each shell had a weight of 47 kg and a tactical range of 25 km. The gun was designed to fire tactical nuclear rounds, but as Sweden decided to not produce nuclear weapons, this feature never came into use.

Use

The plan was to produce about 70 vehicles, but due to cuts in defence budget only 26 bandkanon 1s were manufactured. They were used as divisional artillery in Norrland, used by Bodens artilleriregemente and later Norrbottens regemente. 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 bkan 1 was discontinued in 2003.

Versions

Bandkanon 1 appeared in two versions, the original version was bandkanon 1 (also designated bandkanon 1 A). After modification done to the vehicle during the 1980s, the new version was designated bandkanon 1 C. The main difference was the introduction of a drive train more similar to the one introduced on the new "C" version of stridsvagn 103, strv 103C, other modifications were the removal of the built-in ammunition crane and the introduction of the POS 2 system for navigation, positioning and directing.
