SANK (Saabs Automatiska Navigeringskalkylator – the Automatic Navigation Calculator of SAAB), in civilian version called D2, was the first all transistor computer constructed by Saab.
It was in fact an idea-study supervised by Viggo Wentzel. The goal was to find out if a complete digital computer could fit in to an airplane or a robot. So far only analogic calculators had been used for that purpose.


The unique compact size of D2 made it possible to place it on a desk. The weight was 200 Kg.
