The Viklun launch vehicle is the very first rocket provided by BDB, a small and cheap launcher able to loft only the lightest of payloads. Viklun consists of a Viking-50 powered first stage and an Alpha second stage, which is optimized for vacuum use only.
The Alpha powered 2nd stage can be provided with any combination of 2 different fuel tanks, and can be supplemented by the Aquilae SRM 3rd stage.
While the power of the Viking-50 sets the maximum payload that can be lofted, these additional stages can provide a wide range of possible high apoapsis and / or high inclination orbits.
