Lockheed Martin used a clear versioning scheme for v4:
Includes over 24,000 airports and updated vector data for regions like Africa, Southeast Asia, and the Middle East. Professional Plus Exclusive Capabilities
The capabilities of this software extend far beyond a standard desktop flight simulator. The integration of advanced networking via HLA makes v4.0.23.21468 a powerful tool for training scenarios.
One of the reasons version 4.0.23.21468 remains a topic of interest is its compatibility with a vast library of add-ons. Developers like PMDG, Orbx, and Active Sky released versions of their products specifically optimized for the v4 64-bit environment. Because later versions of Prepar3D (v5 and v6) introduced different weather and lighting engines, some users prefer the stability and established ecosystem of v4. prepar3d v4 professional plus 402321468
The hallmark enhancement of Prepar3D v4 is its 64-bit memory management. In older 32-bit visual simulators, the software was strictly restricted to addressing a maximum of 4 Gigabytes of Random Access Memory (RAM). When ultra-dense airport scenery, global weather layers, and high-fidelity aircraft modules were rendered simultaneously, the simulator would crash instantly from memory starvation.
Operating the advanced features of the Prepar3D v4 Professional Plus ecosystem requires a robust workstation environment. Because this specific license is often paired with multi-channel displays or hardware cockpit components, scaling your PC hardware to match your deployment scope is critical.

Lockheed Martin's (often associated with the SKU/identifier "402321468" in procurement systems) is a high-end simulation platform designed for advanced training and military rehearsal. Unlike the standard Professional or Academic versions, this license includes specialized features for complex combat scenarios and large-scale interoperability. Key Capabilities of the Professional Plus License this software for a specific training project, or
, an "Instructor Operator System" that allows a trainer to control the environment and role-players in real-time. Key Version 4 Innovations (The 402321468 Era) The specific build number 4.0.23.21468
The jump to version 4 was a watershed moment for the Prepar3D lineage because it introduced a .
Introduced real-time illumination, allowing landing lights, strobe lights, and airport floodlights to realistically reflect off surfaces, rain drops, and other aircraft.
The string "prepar3d v4 professional plus 402321468" may initially appear to be a random alphanumeric code. However, it is in fact a specific identifier for a precise version of the flight simulation software. In the context of Prepar3D (pronounced "Prepared"), developed and sold by Lockheed Martin, the number 402321468 breaks down into the version number 4.0.23.21468 . This particular build was the original release version of Prepar3D v4, launched to the public on May 28, 2017. At its core, this specific build transitioned the 20-year-old simulation engine to a modern 64-bit architecture, which significantly enhanced its capability, stability, and graphical fidelity for professional training. One of the reasons version 4
Because Prepar3D is an evolutionary successor to the Microsoft Flight Simulator (FSX) lineage, it benefits from one of the largest and most mature add-on ecosystems in the flight simulation industry. Transitioning to v4 opened the door for incredible performance optimizations. Even when recording in 4K with dozens of third-party add-ons installed, the 64-bit framework allows for smoother frame rates and faster texture loading compared to older simulation platforms. The add-on market is vast:
The latest iteration of Prepar3D, version 4, brings a host of exciting new features and improvements. The Professional Plus edition, in particular, offers a comprehensive suite of tools and features designed to satisfy the needs of even the most demanding flight simulation enthusiasts. Here are some of the key highlights of Prepar3D v4 Professional Plus 402321468:
Includes SimOperator , an Instructor Operator System (IOS) that allows a controller to manage scenarios and role-players in real-time.
