Earth's space navy of the Crisis Era — the fusion-driven Stellar-class warship force assembled across two centuries to meet the Trisolaran invasion, almost entirely destroyed in a single afternoon at the Doomsday Battle by a single Trisolaran Droplet.
The Solar Fleet is the trilogy's great false hope. Two centuries of construction. Generations of officers raised in space. By the time of the Doomsday Battle the Fleet is the largest single project in human history — and it is wiped out in fifteen minutes by a single unmanned Droplet that simply rams the fusion drives in sequence. The few ships that escape — Natural Selection, Blue Space, Bronze Age, Quantum, Ultimate Law — become Starship Earth and then, in the Battle of Darkness, become each other's executioners.
Hundreds of 1,500-meter Stellar-class warships in three regional fleet groups (Asian, European, North American), painted matte gray, fusion-drive bells glowing soft blue when underway. Bases at Jupiter and Saturn. Crews live their entire careers in microgravity.
