Spirit

This is not a Ghost ghost FYI if you still think its a ghost look at the link, ghosts are more bulbous, and blocky. The side jets and guns cannot be found on a ghost, and there is no weird blue tube on the hood. Also wings face other the way on a ghost.  

After the Covenent was defeated, they started working on ProjectS, creating a super vehicle, the Spirit. Capable of taking out all vehicles such as mongooses and warthogs, with ground to air homing missiles that can destroy air combat vehicles with ease. With 4 frontal lasers and homing rocket-launcher, these will pose a large threat to the UNSC!
