The Orca Bomber, designed by GDI's Engineering Corps, is a bomber aircraft first deployed during the Second Tiberium War. The bomber's heavy bomb load allows it to devastate large formations of enemy ground units, however it's slow speed and large radar signature make it easy pray for enemy fighter aircraft and ground-based anti-air units.
Orca Bomber is a flying anti-ground unit that can turn to rubble whole armies in a single bombing raid. If one sortie is not enough to take out heavier units, several bombing raids will do the work. When the Orca Bomber is on the field, it can't be ignored.
The bombing raid is triggered once an enemy unit appears on an adjacent tile. It takes a little while before the first bomb is released. The bombing continues until all six bombs are dropped irrespective if there are any enemy units to target. The bomb blast deals full damage directly underneath the Orca Bomber and adjacent tiles receive 60% of the damage. To maximize the damage output of the bomber, it should be ordered to move over the target back and forth.
Orca Bomber dominates ground, but is vulnerable to air attacks, which requires good anti-air support, best of which is the Hammerhead. Ground based anti-air units like Slingshots are not as effective, since have a good chance of getting damaged by the Orca's friendly fire. On the ground the main threats are the Zone troopers and Sandstorms, especially when they have the defenders advantage.
Another weakness of the Orca Bomber is baiting. Involuntary bombing, friendly fire and long reload times mean that a single scouting unit like Cyberwheel can push behind the front lines, get near the Bomber and trigger the bombing, forcing it to reload at best, bombing the friendly units at worse.
