The Bombardment of Earth was the igniting event of the Interplanetary War, in which several Free Navy vessels launched an assault on humanity's homeworld, throwing significantly large asteroids at the planet, leaving all infrastructure crippled. This brief conflict resulted in the United Nations' declaration of war and evacuation of all governmental personnel to Luna.
Eventually, the entirety of Sol system allied against the authoritarian Free Navy, bringing about the first true interplanetary war.
Ever since humanity had become an interstellar species, the Free Navy had been increasing its belligerency degree. Ultimately, under Marco Inaros and behind-the-scenes directed by W. Duarte, the organization sought the subjugation of the two human epicenters, Earth and Mars, and their extrasolar colonies. Inaros ultimately decided for the effective destruction of Earth's surface as vengeance for the two centuries in which the superpower had been continuously disregarding the Belter populace.
The attack was possible due to the theft of stealth technology by Filip Inaros in the Callisto attack the previous year, which covered the rocks, and allowed them to be undetected until a second before they hit Earth.
3 asteroids struck Earth, each a couple of hours apart. The first one struck at Laghouat, North Africa, the second in the middle of the Atlantic, and the third on the East coast of the U.S. This largely led to a complete breakdown of civil society in large swathes of areas affected, with billions dead within days from tsunamis and earthquakes. In the medium term it completely devastated food production, and energy supply.
Earth was left completely crippled following the bombardment, despite the subsequent C.F. victory. The Martian Congressional Republic and the Outer Planets Alliance ultimately decided to put aside their political differences with the United Nations and work as an emergency unified body which sought the defeat of the barbaric Free Navy. All government personnel who survived were evacuated to Luna.
The UN Navy was recalled from across the system, and formed a ring around Earth to protect it from further incoming asteroids. This led to it being pinned down, and unable to protect the colony ships now trapped in the Belt.
Chrisjen Avasarala became acting UN Secretary-General due to Nancy Gao's death in the strikes.
Total deaths from the attack are unclear. Hundreds of millions died in the initial damage from earthquakes and tsunamis, while billions more died in the coming weeks due to environmental disaster, the breakdown of society, and lack of food or water. In Babylon's Ashes, 15 billion were either dead or beyond saving, with only 5 billion being secure, final casualties were likely to be much higher.UN Secretary-General Nancy Gao was killed in the strikes, as was Arjun Avasarala.
- ↑ Governmental officials were evacuated to Luna. Thus, all instructions and some of the UN's counteract forces came from Earth's satellite.
