Sky Sentry

 is a GDI satellite appearing in Tiberium Wars and Kane's Wrath.

Background
The Sky Sentry satellites are one of the most important tools InOps have at their disposal. Capable of global surveillance and scanning, they are a significant part of Blue Zone protection, allowing for pin-pointing abberant energy signatures, locating Nod bases, even uncloaked ones, and up-to-date intelligence.

In-game
While only mentioned in Tiberium Wars, in Global Conquest mode for GDI, the Sky Sentry becomes an usable support power, allowing the player to temporarily reveal all Nod bases worldwide.
