The Strv 105 was an upgraded version of the Strv 102R, with improved suspension for the tracks, thermal cameras, and new driver hatch. The Strv 105 was decided in the 1990s to complement FVM's procurement of acquiring new tanks for the Swedish armed forces. However, only one prototype was ever built, and the type never entered service due to Sweden acquiring Strv 121 and the vehicle platform became obsolete.

Introduced in Update "Wind of Change", the Strv 105 is a clear upgrade over the Strv 104 with a similar playstyle. The Strv 105 comes with thermals, better APFSDS rounds and slight better performance in mobility which is needed due to the Strv 105 facing more fearsome opponents compared to Strv 104. The Strv 105 is a vehicle that players should take great precaution in: being a Centurion, it's not the fastest or most manoeuvrable vehicle and can face some very dangerous opponents that can outperform it very heavily in terms of speed, manoeuvrability, and firepower. This makes the Strv 105 a better vehicle to support teammates or shoot from a distance where its ERA can protect it better against HEAT-FS and HESH rounds, though it is still very vulnerable to APFSDS rounds. However, it is not by any means a useless vehicle, facing similar opponents like the Sho't Kal Dalet, and can still put up a fight against any opponent with its Slpprj m/90C round giving it a similar penetration performance to DM23.
