Swedish Self-Propelled Artillery Vehicle
The 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.
