Description

GarageImage Strv 103A.jpg


The Stridsvagn 103A is a rank V Swedish medium tank with a battle rating of 8.0 (AB/RB/SB). It was introduced in Update 1.97 "Viking Fury". It is a first unique tank in the Swedish tree which is a MBT, although by its appearance it would seem to instead be a tank destroyer. It is also known as S-Tank or Door Stop.

General info

Survivability and armour

With a superbly sloped front hull armour, incoming kinetic rounds are prone to harmlessly bounce off, though chemical rounds will typically do some damage. Side, rear and top armour of the vehicle are weak, most aircraft can penetrate the roof, especially if they have 20 mm rounds or larger. With a total of three crew members, survivability after taking hits tend to be slim. However, the Strv 103 series are the only tanks that can operate with only one crew member! A major drawback is without transmission/engine you can no longer maneuver the hull to aim left or right.

Armor Composition:

  • Rolled Homogeneous Armor
  • Structural Steel - Storage Boxes
  • Gun Steel - Main Gun, Machine Gus
  • Tracks
  • Structural Steel of Chassis - Suspension

Usage in battles

Describe the tactics of playing in the vehicle, the features of using vehicles in the team and advice on tactics. Refrain from creating a "guide" - do not impose a single point of view but instead give the reader food for thought. Describe the most dangerous enemies and give recommendations on fighting them. If necessary, note the specifics of the game in different modes (AB, RB, SB).

Pros and cons

Pros:

  • Low profile
  • Fast reload
  • Effectively sloped front armour
  • Can be controlled by one crew member
  • Extremely survivable
  • Gunner and Commander perform the same roles, so there is no crew switch if either is knocked out

Cons:

  • Hull aiming (must turn the entire tank to aim left or right)
  • Slow aiming
  • Vulnerable to flanking
  • Only three crew members
  • Gun is prone to damage
  • Catches fire often when shot from the side and sometimes from the front

History

Devblog

In the immediate postwar years, Sweden began looking for a replacement to the Centurion tanks, then in service with its army. The most straightforward solution was to once again look into the export market for potential candidates, although engineers were already working on a domestic design - the Kranvagn. While this process was ongoing, an engineer by the name of Sven Berge came up with a radical new tank design in 1956.

This new vehicle featured a turretless design with a cannon fixed to the hull, which would be trained onto its targets with the precise use of an adjustable suspension system. The design was based on results from a study on tank crew casualties during WWII and the Korean War, which showed a correlation between tank height and hit probability. As such, the ‘S-Tank’ was kept very small in dimensions and low in profile, while also utilizing some innovative new engineering solutions, such as a mixed power plant consisting of a diesel engine and a gas turbine.

In 1959, the Swedish government approved the construction and testing of two prototypes. In 1960, a pre-production batch of 10 vehicles of the ‘0-serie’ was ordered for field trials, which went on into the mid ‘60s.  Generating more than favorable test results, the vehicle was formally ordered into production and procured as the ‘Stridsvagn 103’.

Despite its original purpose being to replace the Centurion tanks in the Swedish Army, the Strv 103 ended up serving alongside it for a number of decades, until it was ultimately decommissioned in the late 1990s. By that time, 290 Strv 103s were built, spanning over five variants.
