Training meets reality with
Lockheed Martin’s Prepar3D ® simulation software

Prepar3D, pronounced “prepared”, is a visual simulation platform that allows users to create training scenarios across aviation, maritime and ground domains. Prepar3D engages users in immersive training through realistic environments.

Ideal for commercial, academic, professional, or military instruction. Prepar3D can be used to quickly create learning scenarios anywhere in the virtual world, from underwater to sub-orbital space.    

Prepar3D offers students and professionals a multi-domain platform to:

  • Experience a scenario before it happens to increase effectiveness and reduce response time
  • Learn and test their knowledge in the same environment in which they will operate
  • Re-create scenarios with operational data and experiment with different variables
  • Experience a learning lab where science, technology, engineering and math principles are taught in an immersive environment
  • Train for scenarios in aviation, air traffic control, ground vehicle operation and disaster response
  • Prepar3D furthers the development of Microsoft® ESP™ while maintaining compatibility with Microsoft Flight Simulator X, allowing many thousands of add-ons to be used within Prepar3D.

Prepar3D can be used for a wide range of learning scenarios including vehicle procedures training, cockpit familiarization, flight planning, air traffic controller training and emergency response preparation. As a commercial-off-the-shelf product, Prepar3D provides a cost- effective training platform that evolves with technology. Take your training to the next level with Prepar3D!

Microsoft© DirectX 12

Rendering engine takes full advantage of the increased performance, realism and control that modern-day graphics cards provide.

Flight Planner

Create a realistic scenario of flying from one airport to another by choosing different types of routes and flight plan types.

Artificial Intelligence (AI)

Non-user entities include highway vehicles, air and maritime vehicles and associated traffic, as well as roaming livestock and wild animals.

Underwater simulation

Real data from the U.S. Geological Survey and bathymetry data are provided for coastal areas.

Realistic scenery

Millions of square kilometers of the earth accurately represent the urban environment. High-resolution (12cm) content is included for specific locations.


Train with others across the globe inin formation flying patterns, shared cockpit scenarios or joint missions. 

Multiple view

A single machine can output multiple views on multiple devices that can be quickly saved and loaded.

Air Traffic Control (ATC)

Communicating with ATC in Prepar3D mimics the way pilots and controllers communicate in the real world.

3D dynamic trees and vegetation

Flora reacts to to wind and rotor wash.

Accurate topography

Regional specific scenery textures all around the world.

Third-party HW Integration

Easy and realistic hands-on throttle and stick (HOTAS) integration. Prepar3D is fully compatible with almost any Windows supported controller or device.

Hardware Agnostic

Setup of hardware across laptops, desktops and multi-monitor systems where a single baseline can be deployed across various hardware devices from a tablet to a dome.

Extensively configurable

Settings and options give full control on what and how Prepar3D performs and simulates to ensure optimized environments for varied uses.

A Professional Plus license enables a suite of additional capabilities for advanced training use cases

Mixed & Extended Reality

Pass-through camera support for blending of physical and digital world to create a seamless training environment

Dynamic Weapons System

Fully configurable to support training procedures related to the employment of bombs, missiles, gun, and countermeasures are included, as are examples to show you how to implement them in your training.


Increased performance on multi-screen and dome setups by enabling the ability to run Prepar3D concurrently distributed across multiple systems.

Customizable AI Behaviors

Enable the creation of scenarios that provide artificial entity interaction with the user. Behaviors include Attacker, Combat Air Patrol, Close Air Support, Pursue, Search, and Wingman.

Distributed Interactive Simulation (DIS)

Connect to a DIS network session and integrate with other simulators.

Common Image Generator Interface (CIGI)

Providing communication between a Host simulation and an Image Generator (IG). Using this simulation interoperability standard Prepar3D can function as either a Host or IG.


Networked Instructor Operating Station (IOS) which allows instructors to control multiplayer scenarios and modify role-players in real-time.
