Covenant Bomb

The Covenant use an Antimatter Bomb (similar to the tactical nukes in the UNSC) to take down large structures or targets. The bomb is about 2 meters long, 1 meter high and is covered in large spikes that keep the bomb in place. These bombs are equipped with timers on their detonators and contain antimatter. Antimatter is extremely unstable, any contact between destabilized antimatter and normal matter causes an instant, massive explosion of energy.

It is a larger version of the Antimatter Charge. The Covenant carry these on their ships, likely for use by the ship Rangers. They are capable of destroying entire ships and even space stations, the example being the MAC stations above Earth. If placed near a reactor, the bomb is even capable of destroying an Assault Carrier, as was done by the Master Chief in Halo 2 during the First Battle of Earth, however an assault carrier would be easier due to the fact that it is hollow, open space.

Trivia

 * It is referred to by Jason Jones of Bungie as the "Giant Covenant Space Pickle".
 * An antimatter particle colliding with a matter particle releases 100% of the energy contained within the particles, while an H-bomb only releases about 7% of this energy. This gives a clue to how effective and powerful this force is.
