The A.T.A.C. (Agile Tactical Air Component) is a flying assault vehicle used by the Helghast, capable of attacking vehicles or infantry. It is also a prototype fighter aircraft transported to Vekta for combat trials by the Elite Guard. Though originally built to offer room to a single pilot, later models were designed to be operated unmanned via remote control, due to a high number of crashes during live tests. The aircraft is a relatively small, fast, and extremely maneuverable attack vehicle that is armed with an awesome array of firepower.

Though it has been under development for quite some time, the Helghast have gathered useful data during trial runs which has enabled them to make useful development modifications before the ATAC would go into final production. However, after the destruction of the SD platform on Vekta, the Helghast have been forced to push the ATAC into active service as part of their defense against the ISA invasion.
