For Microsoft Flight Simulator X (SP2/X-Pack/Gold & Steam Edition)
Please see system requirements, below for important compatibility and support information before purchase!

TacPack for FSX is the first true single and multi-player tactical combat engine for Microsoft Flight Simulator X. In 2010, Vertical Reality Simulation's Superbug X brought the first true fly-by wire combat aircraft to Flight Simulator X, along with a massive list of never-before seen innovations including true avionic and animated weapons modeling with sophisticated and highly integrated fire control and radar suites. The only problem was that weapons couldn't actually destroy anything in the world. We could simulate their destruction by having avionics such as radar ignore them when the hit occurred, but they would always keep flying. TacPack will change everything you thought you knew about what was possible in Flight Simulator.

True Destruction: With TacPack, weapons no longer need to be benign figments of your imagination; Flight Simulator becomes a live battle space with realistically modeled weapons, radar, countermeasures, and early warning systems, all of which work in both single and multi-player. 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 its systems.

Weapons ranging from AGMs to LGBs and guns are all modeled with realistic weights, physics, performance, effects, and lethality envelopes rivaling stand-alone simulators. Take out air defenses like SAM and AAA, or bomb hostile airfields or carriers armed with point-defense systems such as Sea Sparrow and Phalanx CIWS.

Low-level Integration: Seamless integration is what the TacPack is all about; Weapons will appear on the various aircraft stations just as they do in the classic Superbug, or other "normal" models, but as soon as you pull the trigger, the TacPack magic takes over, seamlessly unleashing a deadly accurate simulation for the weapon itself. The TacPack's tactical infrastructure is comprised of a dynamic weapon simulation, radar, ECM, and radar warning receiver backend functions. All the avionics including stores management are tailored to the specific weapon being used. It's as if the TacPack was there all along waiting to be unleashed. Any aircraft can be integrated at a low level via the TacPack SDK.

Software Development Kit (SDK): A TacPack SDK is available, and facilitates royalty-free, license free third-party TacPack integration into aircraft (or other SimObjects such as ships and vehicles). Third party support for the SDK includes developers such as Aerosoft, Dino Cattaneo, Iris Simulations, Metal2Mesh, Milviz, and other well-known developers who are currently participating in SDK integration, but have not yet gone public (as of the time of this writing). With other TacPack-Powered aircraft becoming available, it's finally possible to obtain diverse, cheat-free, air-to-air combat with aircraft other than (or including) the Superbug.

ACMI Playback: When the dust settles you'll be able to call for a tanker, fuel up behind an intelligent AI refueler flying dynamic racetrack patterns, then return to base to review the action (and lick your wounds) via TacView - an amazing ACMI playback system previously reserved for stand-alone simulations. From your cockpit it is hard to know what happened all around you, especially on the other side of the theater... Use Tacview to embrace in a single glance the whole battlefield, while keeping an eye on every little detail which matters. As an instructor, you can now clearly review trajectories, speed, and controls positions so you can show and explain to your cadets how to improve their flight skills.


This webpage simply isn't large enough to list all the TacPack features, so please feel free to examine the full online documentation

600+ Page Wiki (including Superbug). We chose to document the TacPack and Superbug with a massive Wiki, because the products are just too dynamic to contain in a conventional .PDF. The Wiki can be monitored for changes and provides a much more suitable medium for an evolving product.

ACMI Playback:

TacPack Air Combat Maneuvering Instrumentation (ACMI) recording provides a highly detailed log of everything that happens during a TacPack flight in any aircraft. Logs can be loaded into Vyrtuoz's TacView for full 3D playback and analysis.

  • Record and playback flights in any aircraft. Records all aircraft (AI and MP), vehicles, weapons, and even target designations and CCIP predictions.
  • Minimal FPS impact
  • Facilitates after-action debriefing/training

Multiplayer Capabilities:

  • FULL multiplayer functionality
  • Drop AI into sessions. Assets such as SAMs, working carriers, tankers and more may be dropped by team members into the battlefield
  • Partial and critical damage modeling
  • IFF system for all AI and human players to facilitate division into teams
  • Anti-cheating measures. Multi-player is about balance. VRS is making every effort to ensure that the TacPack is fair and balanced, and we will continue to support anti-cheating by design and proactive, ongoing software updates
  • Proprietary TacPack server publishing. See and join hosted TacPack servers
