One of the "Warriors of the Green Planet Trilogy of Games". The games are set on a future Earth that has suffered an "axial flip of 72 degrees", resulting in various disasters and changes that result in this hypothetical post-apocalyptic game world. War of the Sky Galleons is the aerial combat game. Units include Scouting Ships, Cruising Ships, and Ships of Battle. The game provides for boarding, grappling, and lase-gun combat between these airborne sailing ships. A set of expansion rules allowed War of the Sky Galleons to be played together with the companion games Warriors of the Green Planet and Mind War.
