About TacPack

TacPack allows the addition of functional weapons and other tactical systems to TacPack Powered aircraft. It also provides an interface for user-deployable AI such as surface to air threats, aircraft carriers, drones, and aerial refuelling tankers.

TacPack® is a true single and multi-player tactical combat engine for FSX or P3D (requires separate license for each platform). In a nutshell, TacPack enables true combat systems such as lethal weapons, radar, and radar warning receivers to be used in FSX/P3D against single or multi-player adversaries (or yes, even against lowly Cessnas!). TacPack will change everything you thought you knew about what was possible in FSX/P3D. TacPack also features the ability to spawn AI ships (e.g. aircraft carriers with pitching, rolling decks), refueling tankers, drones, and lethal SAM sites directly into the simulation via a handy in-game menu. TacPack is not a system that can be used to instantly attach weapons to aircraft like wheels on cars; TacPack-Powered™ aircraft utilize realistic, deeply integrated systems, and must be built from the ground-up using the TacPack SDK. It is therefore recommended (but not required), to acquire one or more TacPack-Powered™ aircraft in order to take full advantage of what the TacPack has to offer. Fortunately, there are many TacPack-Powered™ aircraft choices, and the list is growing daily.

Lethal Tactical Systems

Lethal weaponsWith TacPack, great FSX/P3D military aircraft no longer need to fly half-baked. The full potential of the aircraft's capabilities can finally be realized with the addition of true tactical systems. The normally benign landscape is transformed into a live battle space with realistically modeled weapons, countermeasures, team-based IFF and early warning systems. Weapons will appear on the various aircraft stations just as they have with previously static models, but instead of a "sigh" when trigger is pulled, TacPack magic takes over, seamlessly unleashing a deadly accurate weapon simulation. Your aircraft can destroy (or cripple) your adversaries, and you yourself can become the prey, taking partial or critical damage. All systems work in both single and multi-player. Weapons ranging from Air-to-Air missiles to Zuni rockets are all modeled with realistic weights, physics, performance, effects, and lethality envelopes rivaling stand-alone simulators. Take out aircraft and ground targets, evade air defenses like SAM and AAA, or try to penetrate carrier point defenses with sea-skimming missiles - all in single or multi-player.

Team-Based AI Spawning

AI spawningTacPack comes with an ever-improving AI system which includes the ability to spawn assets into the sim directly from within FSX/P3D. These include vessels such aircraft carriers (carrier models not included, but works with any payware or freeware ships) which can be armed with point defense systems and navigation aids, SAM sites, refueling tankers, and drones. An in-game menu system lets you spawn the AI at relative positions from ownship and optionally assign teams to them. Setting up a scenario can be as simple as plopping them down in front of the aircraft, or as complex as writing a TacPack scenario file to deploy them automatically with each flight.

The TacPack also includes an external management application called the TacPack Manager (TPM), which allows customization options ranging from carrier navigational frequencies and refueling drogue parameters, to multi-player host options.

Royalty-Free SDK

SDKSeamless developer integration is provided via the freely licensed TacPack SDK. The TacPack's infrastructure is comprised of a dynamic weapon simulation, multi-mode radar, ECM/ECCM, IFF, and radar warning receiver backend functions. All the avionics variables 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 by developers at a low level via the TacPack SDK. Again, there are no royalties associated with use of the SDK (commercial or otherwise), but the end-user must have the TacPack installed in order to leverage the TacPack-Powered™ aircraft features.

The TacPack SDK is available to owners and developers alike, and facilitates royalty and license-free third-party integration into aircraft or other SimObjects such as ships and vehicles. Third party support for the SDK includes developers such as Aerosoft, India Foxt Echo, Metal2Mesh, Milviz, and more! With other TacPack-Powered™ aircraft becoming available frequently, it's finally possible to obtain diverse, cheat-free, air-to-air combat with aircraft other than (or including) the Superbug.

TacView ACMI Support

SDKWhen 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. The TacPack can export the entire flight with dozens of parameters including missile launches and bombing runs. Visualize radar locks and missile behavior to efficiently analyze both BVR flights and dogfights. From aspect angle, to G forces, display and compare any telemetry parameter in tables, on aircraft, and labels in the 3D view. Analyze the flight envelope and performances like corner speed by drawing detailed charts in just one click! You can even export telemetry data for deeper analysis in your favorite spreadsheet.



The TacPack is changing constantly with new features being added with almost every build. Because of this, we chose to document the TacPack with a wiki, because the product is far too dynamic to benefit from a conventional static source such as .PDF. The wiki can be monitored for changes and provides a much more suitable medium for an evolving product. Please fee free to read it prior to purchase!

Product DRM

All VRS products require internet-based activation.


Each product comes with a finite number of activations at the time of purchase. If you subsequently change hardware or operating systems and fail to deactivate ]prior to the change(s), the activation count may be decreased by 1. If you completely run out of activations, you will no longer be able to activate the software, and must contact VRS to have the activation count reset. This is easily avoided by following the procedures for deactivation BEFORE making hardware changes. Please note that we do not "top off" activations. Please wait until you're out (error 300) before contacting us.


In order to avoid losing activations, the software may quickly be deactivated prior to making hardware or operating system changes. This is done from the Help menu under Registration Details in either the TacPack Manager (TacPack) or Aircraft Manager (Aircraft).
