Is there a anti air scarab on Halo 3?

In Halo 3, there is no specific anti-air version of the Scarab. The Scarab is primarily a ground vehicle used by the Covenant, equipped with a powerful main cannon and a turret that can engage ground targets. While it can indirectly affect aerial vehicles due to its firepower, it does not have dedicated anti-air capabilities like some other vehicles in the game.
