Lockheed Martin released Version 4 of its Prepar3D® simulation and training software solution. Lockheed says the Prepar3D v4 relies on 64-bit architecture to deliver unparalleled realism.

This new version features major visual upgrades including enhanced virtual reality support, a new lighting system, 3D weather capabilities, 40 high-detail cities and more than 24,900 airports across the globe. The new release also features improvements to performance and a fully redesigned user interface.

"Training meets reality with Lockheed Martin's Prepar3D® simulation software, and v4 provides unprecedented realism," said Sandy Samuel, vice president, Training and Simulation Solutions. "While initially the premier tool for training both commercial and military aviators, Prepar3D has grown to drive simulation for almost any vehicle in the air, at sea, underwater or even in the depths of space."

Prepar3D v4 provides tools to simplify the process of creating courseware for self-paced training environments and instructor-led classrooms. The company says it partnered with commercial and internal users to help redesign its Software Development Kit (SDK) that  enables third-party development of custom add-ons, from the ground up.
