With the Swedish tech tree announced, we figured that people might be interested in knowing how closely it aligns with historical Swedish tank designs, so we can pre-emptively fend off accusations of paper tanks and clones, etc. Let’s have a look at each tank in the tree to see how it holds up to closer scrutiny.

Strv fm/21

Originally a German design called LK II, but it was never used in its country of origin. Ten tanks were delivered to the Swedish army in 1921-1922. They were in service until the late 30’s, mainly as tech demonstrators and for tank doctrine studies – they were not really intended for use in the field.
Medium/heavy branch

Strv m/38

Designed at AB Landsverk in Landskrona, Sweden as a member of the rather successful L-60 family of light tanks. The Swedish army bought 16 tanks of this early variant, with deliveries starting in 1938. The in-game version also includes modules from an improved variant, strv m/39 – another 20 tanks of that variant were delivered 1939-1940. Both variants were in service until 1957.
Strv m/40L

A further upgrade of the strv m/38 and m/39. The in-game version also includes modules from the m/40K variant. A total of 180 tanks delivered to the Swedish army between 1941 and 1944. Strv m/40L remained in service until 1957, m/40K until 1960.
Lago

Designed at AB Landsverk in Landskrona, Sweden in the late 1930’s for the export market, more specifically Hungary. One prototype was manufactured and tested. The design was then adapted into the strv m/42.
Strv m/42

Based on the Lago, this tank was developed in cooperation between AB Landsverk and the Royal Army Ordnance Administration for the Swedish army. A total of 282 were delivered to the Swedish army between 1943 and 1945 in various configurations. The tank in its original form remained in service until 1957-1960, at which point most were modernized and turned into strv 74’s.
Strv 74

A strv m/42 with a slightly modified chassis and a new turret, designed by the Royal Army Administration. 225 were built from existing strv m/42 hulls in 1957-1960, and most were in service with the Swedish army until the late 1970’s, with some examples surviving as late as 1984.
Leo

Designed at AB Landsverk in Landskrona, Sweden for the export market in the late 1940’s. The design was offered to Siam (today’s Thailand), Pakistan, Ireland and Switzerland, but there were no buyers and the design remained on paper.
EMIL

EMIL II

Kranvagn

These designs are from various stages of the Royal Army Ordnance Administration’s EMIL project, which aimed to develop a new modern tank for the Swedish army, starting in 1951. EMIL and EMIL II are based on paper designs from earlier stages in the project, while Kranvagn is based on the final design. Two prototype hulls of that design were built and tested (with one being convered to the artillerikanonvagn 151 SPG that was a prototype for the bandkanon 1), but the turret only got to the wooden mockup stage. The project was cancelled in 1958.
TD branch

Pvlvv fm/42

An experimental mini-SPG useful for both AA and TD duties, designed by the Royal Army Ordnance Administration and intended for company-level support for armored formations. One prototype built and tested as a feasibility study in 1942. The designation is fictional – it was never given a name.
Ikv 72

Designed as a cooperation between AB Landsverk and AB Bofors in the late 1940’s and early 1950’s in response to a Swedish army request for a very light infantry support SPG. 36 delivered to the army starting in 1952. Was soon upgraded and upgunned and then renamed the ikv 102, and in that form it remained in service until the mid-1970’s.
Sav m/43

An infantry support SPG (think StuG) based on the Czech TNH light tank chassis, designed at the Royal Army Ordnance Administration in cooperation with AB Scania-Vabis in Södertälje, Sweden between 1942 and 1944. A total of 36 were delivered to the Swedish army between 1944 and 1947. They remained in service until 1973.
Ikv 103

An improved version of the ikv 72. 81 delivered to the Swedish army starting in 1956. Like the ikv 102’s, they remained in service until the mid-1970’s.
Ikv 65 alt II

Designed at AB Landsverk in Landskrona, Sweden in the late 1960’s as a response to a Swedish army request for proposals for a new infantry support light SPG. There were many alternative designs from several different companies – this was Landsverk’s most detailed one and the one they favored. A very detailed scale model was built, but since a competitor’s design was chosen instead, the design otherwise remained on paper.
Ikv 90 typ B

Designed at AB Bofors in Karlskoga, Sweden in the late 1960’s as another response to the request mentioned above. Just like in the Landsverk case, the design remained on paper since AB Hägglund & söner’s design was chosen instead.
UDES 03

Designed at the Defence Materiel Administration in cooperation with AB Hägglund & söner and AB Bofors in the early 1970’s as an experiment with a lighter, cheaper strv 103. Two prototypes were built and tested.
Strv 103-0

Designed at the Royal Army Administration in cooperation with AB Bofors in the late 1950’s and early 1960’s, initially as a feasibility study, but then as response to a Swedish army demand for a new tank. The 103-0 represents the “zero-series” of about a dozen prototypes built in the mid-60’s. Was not in any way a TD or a defensive tank.
Strv 103B

The “real” production version of the strv 103-0. The original version, strv 103A, only lasted for three years and 70 tanks – all 70 were immediately upgraded to 103B standard almost as soon as they got off the production line. A total of 290 strv 103’s were delivered to the Swedish army between 1967 and 1971. They remained in service until the mid-1990’s.
So, to sum it up: out of ten lights/mediums/heavies, a total of five were in service in the Swedish army, two were prototypes and three remained on paper or as a mockup. Out of nine TD’s, four were in service, three were prototypes and two remained on paper. Other than the strv fm/21, which was a German design, and Sav m/43, which was based on a Czech chassis, all were designed and developed in Sweden.
