Interstellar Colony Vessel

These craft, housing thousands of people each, travel off into the stars. With vast, proton-proton reactors, they glow like small stars, putting off 188 petawatts upon startup, more than a K1 civilization. They disspate this with vast radiators, kilometers across. However, even with this tremendous power, the heavily laden ship only inches forward at 0.01 g, or 9.8 cm/s^2. They will continue at this power for up to 14 years, over 1 light year, to a final speed of up to 15% light speed. When this happens, the lower stage will seperate, and then slowly make its way back to the SS. Inside this ship, along with thousands of tons of spare materials, hundreds of subcraft and a whole vault of gene samples, live up to 36000 people in a shrunken O'Neill Cylinder. Here they will spend the decades and even centuries nescessary for such a voyage. However, these ships always travel in groups, so it is like a small community of space stations for the voyage.
