From Gizmodo:

This is the ultra-high resolution multi-projector VR system that will be used for training at the Nellis Air Force Base in Nevada. Built by Lockheed Martin, it uses Mersive Sol Server technology to automatically and seamlessly combine multiple projectors in one gigantabolous immersive display, thanks to camera-based fully-automatic calibration, edge blending and color correction. The whole system will be used in the base’s Joint Terminal Attack Controller (JTAC) Virtual Trainer Dome simulator, which is “primary training facility for the USAF JTACs.”

JTAC is the link between the Army and the Air Force when combat requires the aid of close air support, is expected to maintain situational awareness, know the supported unit’s plans, and validate and prosecute targets of opportunity. The I-JTAC TRS Proof-of-Concept Dome, built by Lockheed Martin, offers a high fidelity, realistic, fully immersive, real-time visual environment with sensor, simulator, and database correlation.

You know you wanna play with it.
