The first and second image are of a possible crewed vehicle that's Soyuz like (the diameter of the descent module is 2.4 meters and the bottom of the service module is 2.8 meters). All the other stuff like solar panels and docking stuff will be added later when I import it into blender. The third is a image of what the bottom of the first stage could look like with it's 4 Ukko alpha engines (the diameter of the first stage is 2.6 meters BTW and part of the engines will be covered in the final design), the fourth is the second stage (1.6 meters wide) with 1 Pohjala alpha engine and the fifth is of a 2.6 meter wide second stage with 2 Pohjala alpha engine. And the Rocket with the 1.6 meter will have a S1 at the end of the name (So like Finlandia alpha S1) and if it's the 2.6 meter one it'll have S2. And then when booster are added on the S2 it'll be S2-n (with n being the number of boosters with 6 being the max). The S2 and S2-n will be used for bigger payloads and the crewed vehicle. Obviously the first launch of a Finlandia alpha will use the S1 because a S2 for the first flight is overkill.

Also the Ukko alpha will be open cycle instead of the closed cycle oxidizer rich as originally planned and Pohjala will basically be a scaled down Ukko with a nozzle extension for more efficiency in space
