History

The Stridsvagn 103 (Strv 103), also known as the "S-Tank", is a Swedish post-World War II main battle tank, designed and manufactured in Sweden by Bofors AB (and to some extent Landsverk AB). It was developed in the late 1950s to the mid 1960s and was the first main battle tank to use a turbine engine, as well as the first, and so far only, service tank to not feature a turret. While some might argue that the S-Tank is not a tank, or that turretless casemate vehicles can be called tanks, it is a fact that the S-Tank was designed as, deployed as and used as a tank by the Swedish army. Besides lacking a turret it was however the first tank with a fixed main gun, meaning that the gun was fixed in the hull on both the X-axis and Y-axis. To aim the gun horizontally the entire vehicle had to be steered side to side (same as the hull gun on the B1 bis). To aim vertically the tank used a new type of controllable suspension, probably also a first in the world, that allowed the tank to tilt forwards and backwards using gas-hydraulic hydropneumatics.

Besides tanks the chassis has also been used for other AFV projects, such as the Bkan 1C Self-Propelled Artillery Gun (SPAG) and VEAK 40 Self-Propelled Anti-Air Gun (SPAAG).

S-Tank name

The name "S-Tank" is not an English nickname for the tank, but actually a translation of the Swedish name "Stridsvagn S". Stridsvagn S was the name given to the design during its development and it also became the product name for it after development had finished. The "S" in the name S-Tank refers to "Special" and "Sweden" (Sverige). It was one of three base-designs that competed against each other to become Sweden's next generation MBT during the mid to late 1950s. The other two base-designs were called "Stridsvagn A" (the A-Tank) and " Stridsvagn T" (the T-Tank). The A-Tank followed the Anglo American (Swedish: Angloamerikansk) US/UK design principle of a heavily armored turreted MBT such as the M48 Patton and Centurion. The T-Tank followed the German-French (Swedish: Tyskfransk) design principle of a mobile lightly armored turreted MBT such as the Leopard 1 and AMX-30.

Strv 103-0

Strv 103-0 is the pre-production series of the S-Tank (series 0), delivered to the Swedish Army in 1963. The 0-series consisted of 10 vehicles ordered in 1960 after succesful trials with the two initial strv 103 prototypes S1 and S2. The series was primarily used for field and equipment trials prior to the delivery of the main production series (sub-series A) to the Swedish Army. They are known for their varying equipment, such as lack of rib-armor and domed commanders cupola initially planned to mount an external 20 mm automatic cannon. The same cupola was fitted to the Pbv 301 IFV, albeit with the 20 mm gun.

Strv 103A

Strv 103A is part of the main production series of the S-tank (sub-series A), delivered to the Swedish Army from 1967. Sub-series A consisted of 70 vehicles ordered in 1964 after successful trials with 10 pre-series strv 103-0. Strv 103A was initially used to train instructors and it was not until 1968 that conscription courses began. Strv 103A was short-lived. Its 300 hp gas turbine had proven to be underpowered even before delivery, resulting in the next series (sub-series B) being uprated with a stronger engine. Sub-series B (strv 103B) was delivered between 1970 and 1971, during which the 70 sub-series A vehicles was updated to strv 103B standard in parallel.

Strv 103C

Strv 103C was the last variant of the strv 103 tank to see service, delivered to the Swedish Army from 1986 to 1988. Strv 103C was a modernization upgrade (REMO = Renovation & Modification) for the existing strv 103 tank-fleet in Swedish service, initialized between 1978 to 1982. The upgrade included a stronger piston engine, improved transmission, flare launchers, jerrycans filled with diesel as skirt armor, new tracks and integrated lazer range finder and dozer blade for all vehicles (previously only certain vehicles had laser range finder and dozer blade).

VEAK 40

VEAK 40 is a Self-Propelled Anti-Air Gun (SPAAG) prototype based on the S-Tank chassis developed by Bofors from 1962 to 1968 as part of a longer Swedish Army project to find a replacement for the Lvkv fm/43 SPAAG from WWII. One prototype was delivered in 1965 and proved during testing to be ahead of its time. However the Swedish military decided to focus resources on the Swedish Air Force, rather than the Air Defence, resulting in the VEAK 40 project becoming too expensive to finish.

Bkan 1C is a Self-Propelled Artillery Gun (SPAG) based on the S-Tank chassis, initially developed by Bofors from 1960 to 1965 as part of a longer Swedish Army project to develope a modern autoloading SPAG in calibre 155 mm. The initial bkan 1 version was delivered to the Swedish Army from 1965 to 1969 and used the strv 103A's underpowered powerpack, subsequently receiving the suffix A. In 1988 it was decided to upgrade the powerpack of the existing bkan 1A vehicles to the stronger strv 103C powerpack, redesignating them bkan 1C. However only the piston engine was upgraded as per C-standard in the end.
