For Microsoft® Flight Simulator X (SP2/Acceleration/Gold)
Please see system requirements, below for important compatibility and support information

Superbug X is the most detailed and accurate simulation of a combat aircraft ever developed for Microsoft® Flight Simulator. The Superbug is the culmination of almost 6 years of work, and continues to be supported with frequent releases. From avionics to weapon systems, if it's in the real aircraft, it's probably in this simulation! The Superbug, is the first (and only) true 3-axis fly-by-wire combat aircraft designed for FSX. The flight control system is not "fly-by-wire-like", it's a dynamic, fully control-law-dependent proportional control system driving a single (ordinance independent) neutrally-statically-stable base flight model. The FBW system extends to 100% custom autopilot functions.

The FSX version of the Superbug takes all of the fantastic innovations we developed for FS2004 to a new level of graphic nirvana. The 2D and VC models were reworked and re-textured with high resolution FSX native materials including detailed specular and bump maps. Draw calls were reduced by approximately 20%, and new skinned-mesh animations were added. Effects for missile flyout were introduced that allow plumes and smoke trails. New g-induced and mach-based vapor effects, afterburners, fresnel-based lighting, and a slew of other improvements round out this incredible new FSX package.

Crafted by a small, dedicated team of developers who also happen to be engineers in real life, the Superbug seeks to provide what we believe is by far the most comprehensive overall simulation of ANY combat aircraft ever created for the Flight Simulator franchise. VRS has created a truly remarkable and faithful reproduction of the U.S. Navy's newest strike fighter. Systems ranging from tactical (functioning weapons and sensors) to dedicated, custom fuel, hydraulic and ECS simulation designed [strictly] based on the U.S. Navy's NATOPS flight manuals for this aircraft. Everything from the working and accurate radar, to the early warning and navigation systems are meticulously recreated in extreme detail and fidelity.

The Superbug is also a fully TacPack-Powered aircraft, meaning Superbug owners who also own the TacPack will have vastly expanded cababilities, including live weapon combat systems, FLIR video, NVG video, AI object spawning and much much more. Your aircraft can destroy (or cripple) your adversaries, and you yourself can become the prey, taking partial or critical damage. Note that only multi-player users who own the TacPack (and have it enabled) will be vulnerable to TacPack systems. For more information about the TacPack and all it offers, please refer to the TacPack product page.

The Superbug is the recipient of multiple awards including the coveted Avsim Gold Star (both versions), PC Pilot Magazine's Platinum award, and the 2011 SimFlight Award for Best Military Aircraft. These are the highest review awards available in their respective mediums. If you've tried military aircraft for MSFS before, and they've left a bad taste in your mouth, give the Superbug a try and see why VRS has been called "The PMDG/Level-D of military addons." Let us craft YOU a killing machine!

Explore all the Superbug has to offer by selecting a topic from the left, below. We think you'll agree, the depth of the simulation is second to none, making this an investment you can be proud to add to your collection.

  FSX: System Requirements

The following system requirements should be met to at least the minimum requirement in order to run the VRS Superbug at acceptable frame rates. The Ultimate requirements are obviously not necessary, but will greatly enhance your flying experience. The following figures for Minimum, Average and Ultimate frame rates should only serve as a guide. There are far too many variables associated with Flight Simulator and the Superbug to make accurate predictions. Think of these figures as a general guide - nothing more.

FPS between 10-15.
Avoid high-density areas
FPS between 15-25.
Enjoyable under the majority of conditions
FPS between 25-45.
Excellent performance under most conditions

Required for initial product activation

Important Additional Notes:

  • Joystick mandatory. Full HOTAS (separate stick and throttle), and rudder pedals are highly recommended in order to enjoy this product to its fullest potential.
  • Force feedback NOT supported. The FBW system does not currently support FSX force feedback due to a limitation of FSUIPC. If you have a force feedback stick, the FF function must be disabled in MSFS. There is a working (and better)  alternative to FSX force feedback here.
  • PFC (brand) throttle quadrants are NOT supported due to a proprietary interface. These units to not enumerate through MSFS and are therefore incompatible.
  • Not all features available during online play. Due to certain incompatibilities and limitations of multiplayer sessions, not all animations and/or features may function. Some functions, including radar, may require additional third-party components and/or utilities in order to operate.
  • *FSX DX10 "preview" mode NOT  supported. Although a DX10 or DX11 GPU is fine, FSX itelf has an experimental DX10 mode called "DX10 preview mode". This mode, or setting within FSX must be disabled in order to achieve compatibility with certain TacPack functions if the Superbug is used with the TacPack.
