A City Destroyer is a large alien vehicle used by the aliens from Independence Day to destroy cities, as their name implies. They are detached from the Mothership to inspect life on other planets. There were dozens of these ships seen in the film Independence Day.
The City Destroyers are very large and can cover nearly an entire state (or at least half). In the very center of a City Destroyer is a large group of wing-like plates the unfold to allow large and violent explosions of blue light, which can wipe out an entire city. The back of a City Destroyer has a sunken-in sphere-like hole which has a fin.
- The texture of a City Destroyer is very similar to that of the Mothership.
- The City Destroyers were the only alien vehicles other than the Troop Transports to not have been seen from the inside.
