For Microsoft Flight Simulator X (SP2, Acceleration or Steam Edition*)
*Steam Edition support requires TacPack-Powered versions of the Superbug (i.e. the TacPack is required)

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 10 years of work dating back to FS2004, 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 a "fly-by-wire-like" CAS, it's a completely dynamic, fully control-law-dependent proportional system driving a single (ordinance independent) neutrally-statically-stable base flight model. The FBW system extends to 100% custom autopilot and flight director functions.

State of the Art Graphics: The FSX version of the Superbug takes all of the fantastic innovations we developed for FS2004 to a new level of graphic nirvana. 40 liveries with squadrons from every Carrier Wing in the US Navy are represented using detailed sets of maps with FSX native materials including specular and bump maps. Thanks to efficient modeling techniques from life-long real-time modeling pros, detail down to individual wires and bolts can be enjoyed while still maintaining extremely high frame rates. For those who own the TacPack for FSX, the already feature-rich Superbug is expanded even more, with hundreds of additional features and enhancements ranging from working combat systems to enhanced model graphics.

Uncompromising Realism:  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 front-line strike fighter. Systems ranging from functional tactical weapons and sensors, to dedicated fuel, hydraulic, electrical and ECS simulations designed [strictly] based on the U.S. Navy's NATOPS flight manuals for the aircraft. Everything from the working and accurate radar, to the early warning and navigation systems are meticulously recreated in extreme detail and uncompromising fidelity.

Aircraft Configuration Manager (ACM): The Superbug includes a very powerful external application referred to as the ACM, which may be used to manage aircraft systems and simulation preferences. The ACM provides functions to maintain and edit saved loadouts (weapon sets), program the Mission Unit (MU), set initial fuel loads, and even arm failures. Aircraft preferences are also available for everything from avionic to graphic options. Finally, the ACM can gather and export vital logging information about the state of the Superbug and the simulation in case help is needed diagnosing a support issue.

TacPack Powered: For those who also own the TacPack for FSX, the Superbug will have vastly expanded capabilities, including live A/A and A/G combat systems, FLIR video, NVG video, AI object spawning and much much more. Even the external and internal models have been completely overhauled for the TacPack-powered version. 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 FSX product page.

Rich History with Continual Updates: 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!

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 itself has an experimental DX10 mode called "DX10 preview mode". This mode within FSX must be disabled in order to achieve compatibility with certain TacPack functions if the Superbug is used with the TacPack.
