VDSX-7:
"Christ... These little bastards are fast as hell." - Erikson, callsign Helios.
The Vulture Design "Suppressor" X-7 or the VDSX-7, and also known as "Void", is a combat drone based on the chassis of a EADS Barracuda. It is only equipped with a TLS, and known to be very fast and agile. All it takes is one missile.
X-PF-2:
"Railgun bandit! Watch out!" - Hamilton, callsign Warface.
Experimental Airframe - Parasite Firefly, or 51GNUS, is a fighter aircraft controlled by A.C.I (Aerial Combat Intelligence), an AI developed by Valhalla Industries. Based on the SR-91 Aurora, the X-PF-2 is armed with a railgun and a few missiles. Watch out.
PW-MK-1-SSF:
"A Storm variant?! You got to be kidding me! This thing's a beast!" - Sarah, callsign Okami.
SSF stands for "Super Storm Fighter," and this aircraft is armed to the teeth. Two railguns. A TLS, 20mm cannons, and its multi-purpose missile capacity has increased. From just two, to eight. Probably why it's known as the Storm Weaver, or Devourer of Gods.
PW-MK-1-YSF "Infernum":
"My god.. that thing is huge as hell." - Theodore , callsign Minister.
The largest variant of the PW-MK-1. This is the Godzilla of the series. Armed with the monstrous railgun, the Volcanic Rupture. Rest of the armament is same as the Storm Weaver, but... try to stay away from its railgun. Its damage is devastating.
