Stormhawk
The Stormhawk or Stormhawk Interceptor is a slightly less retarded and more heavily armed cousin of the infamous flying toaster, the Stormtalon. Despite being more practically designed for a Space Marine jetplane, the Stormhawk is by no means original. In fact, the Stormhawk has been accused of stealing the ideas of converted and customized Stormtalons due to the latter's retardation, this has put Games Workshop in a awkward position as they are now seen as stooping so low as to rip off the designs of their customers.
Ranting and accusations aside, the Stormhawk is meant to improve on the Stormtalon by having more frontal armor to cover the fragile cockpit and having a ridiculous array of firepower for a fighter no bigger than a civilian car. It is also built to be dedicated interceptor rather than a gunship, meant to excel at aerial superiority, a position that the Stormhawk can apparently only be comfortable with after almost every other space marine aircraft was nerfed to only be effective against ground targets. So, in typical GW fashion, you need the damn thing now. Oh, wait, since fighters can't shoot effectively at ground targets, you actually need both the Stormhawk and the Stormtalon now.
Stormhawks boast impressive firepower including twin Assault Cannons, an Icarus Stormcannon or Lascannon, twin Heavy Bolters, Typhoon Missile Launchers, or Skyhammer Missile Launchers, and a Infernum Halo Launcher. And yes, it still looks like a GDI Orca, just a Tiberium Wars era one instead of a C&C 1 era one.
