Rocketships constructed for orbital defense around the planets and moons of the Outer Solar System. Designed for a C.E. ~2100 hard sci-fi alternate future I call Solar Conflict (or Solar Frontier, for the non-wartime years).

Models derived from these designs fit nicely into the Full Thrust 2nd Edition tabletop rule system by Ground Zero Games, available for free at their website: https://shop.groundzerogames.co.uk/rules.html

The designs are heavily inspired by Atomic Rockets: http://www.projectrho.com/public_html/rocket/index.php
