Aerotech? dispatched two colony ships to found colonies on Vesta? and Tellus? before the outbreak of the war. These were considered by the Chigs to be invasion forces. Since they were expected to travel beyond the reach of any AI threat they were unarmed and so unable to defend themselves.
These ships were incapable of independant interstellar travel, relying instead on wormholes to reach their destination. As a result launch times from their ground based facilities (the Francis R. Scobee Colonial Launch Center, Corpus Christi, Texas, USA). Upon arrival these craft could land and then be disassembled for parts to help found the colony. The Tellus colony craft managed a crash landing even after being strafed by Chig fighters.
