Description
Developed from 1969 through 1971 as a modernization of the Strv 103. Unlike the previous Strv 103A version, the Strv 103B was equipped with a more powerful gas-turbine engine, laser rangefinder, and infrared devices. The vehicle also accommodated the mounting of amphibious add-on equipment. In 1970, 220 vehicles went into service. At the same time, the vehicles of the previous modification were converted to the Strv 103B, which resulted in a total of 290 vehicles by 1971.

In late 1964, after it became clear that the Strv 103 prototypes and pre-production vehicles had achieved the most important requirements placed on them, and the decision was taken to place an order for the production version. The first production batch included 70 vehicles with the first entering service in 1967 under the designation Strv 103a. In 1970, another batch of 220 vehicles followed, this time with modifications made as a result of the testing with the 0-series. The most important change was in the gas turbine: the 0-series and Strv 103a had both been equipped with the Boeing 502 (300hp) gas turbine, which had been found underpowered. In the Strv 103b, Boeing 502 was replaced with the Caterpillar 553 (490hp), which, combined with the Rolls-Royce K60 diesel engine, produced 730hp, giving the tank the power to weight ratio of 18hp/t. The Strv 103b also introduced the built-in swimming equipment, the dozer blade, and a laser sight to the production model. The Strv 103A were soon upgraded to B-standard. Adjustments to the hydro-pneumatic suspension increased elevation range from -10 through +12 degrees, to -11 through +16 degrees.
