In this second part of the Inside the Chieftain’s Hatch episode about the Strv 103 tank, Nicholas “The Chieftain” Moran looks at the crew positions, height restrictions, the number of people required to control the S-tank, and show the unique position of the radio operator/driver who faces backwards.

Video: WoT – Turretless Swede

Wargaming Europe has released a new video on the history of the Swedish Strv-103 “S-Tank.”

Was the S-Tank a tank destroyer?

A recent video by World of Tanks on Swedish tank history makes the claim that the Swedish Stridsvagn 103, also referred to as the S-Tank, was intended to function as a tank destroyer.  The blog Swedish Tank Archives has taken issue with that assessment in a well researched rebuttal titled Stridsvagn 103 Was Not A Tank Destroyer.

We have taken the liberty of reprinting the first couple paragraphs of the article followed by a link to the Swedish Tank Archives where the entire piece can be viewed.

Stridsvagn 103 Was Not A Tank Destroyer

In internet arguments and popular culture, it is frequently claimed that the stridsvagn 103 (strv 103, “S-tank”) was a defensive tank, or basically a modern tank destroyer. It was, claims the common wisdom (perpetrated and repeated in media such as History Channel), meant to dig down in a forest, take a few shots at attacking Soviet tanks and then retreat, using its rear driver to its advantage. In the recently revealed Swedish tree for World of Tanks, it is indeed classified as a tank destroyer (although mainly for game mechanics reasons). Even in the Swedish army, some officers (although mainly ones who had no experience on the tank) thought it was worthless for traditional tank work – that is, offensive tasks. In this essay, I will show that this is simply not true: the Swedish army set out to figure out how to build a good tank, came up with the S-tank idea, developed and built that idea as a tank, which it then proceeded to use operationally as a tank.

The origins of the strv 103, or “alternative S”

Bofors-FB-P-30304In 1957, the Swedish army initiated a study of the future of warfare, in order to determine what weapons technology it should pursue during the 1960’s – as well as many other things. One of the sub-committees of this study was tasked with studying direct-fire infantry support weapon systems, such as tanks, anti-tank weapons, direct-fire crew-served weapons, etc. The central question that the sub-committee was tasked with answering was: “How should our system for direct fire (both anti-tank and anti-personnel fire) work around 1970 and in the time immediately thereafter?”

From the Vault: The Gas Turbine and the S-Tank

When most people think of a gas turbine in a tank, they probably think of the M1 Abrams or maybe the Soviet T-80.  However, the first MBT to utilize a gas turbine was the rather unusual Swedish “S-Tank” STRV 103.   The S-Tank was the most unusual design of its day and its engine layout was unusual as well.  Rather than have a single engine, the S-Tank had two, a 490 HP gas turbine and a 240 HP diesel.  The tank could be run on just the diesel engine when stationary or moving at low speed, when moving at full speed both engines were engaged for a maximum power of 730 HP.  This article from the March-April 1973 issue of ARMOR details the design of the S-Tank layout.  The article author is Sven Berge, the Swedish engineer chiefly responsible for the S-Tank design.
