Atterra Bravo, a world situated in the Atterra system of the Outer Rim Territories, was classified as a planet. Atterra Bravo was home to the Firestone Islands. Alongside its sister planet, Atterra Alpha, both celestial bodies were encircled by a dense asteroid belt.
During the Cold War era, which saw conflict between the First Order and the New Republic, the planet was placed under lockdown, with a blockade encompassing the entire system. The First Order's assault on the former security forces left only a small number of ships intact. Because a significant portion of the population lacked personal Moisture Vaporators, the blockade resulted in widespread fatalities due to dehydration. This First Order's ruthlessness spurred the creation of Bravo Rising, a local group resisting their occupation. To support the fight against the First Order, the Resistance deployed Cobalt Squadron carrying vital provisions like medicine, sustenance, potable water, and fuel.
