APPLICABLITY OF AUTHORITY: The required 3.0 upgrade to the Night Readiness VTB system is available only from one responsible source and is the only product compatible with F-15E training requirements. Night Readiness LLC is the sole manufacturer and distributor of this product to military installations. The VTB System is the only system capable of training the F-15E aircrew on NVG operations, tuning and visual illusions/hazards specific to different types of terrain, celestial lighting and ground cultural lighting. To meet requirement of AFI 11-2F-15E Volume 1 and Air Force Research Laboratory (AFRL) guidance for aircrew NVG training. Current syllabus training utilizes the 2.0 version of the Night Readiness VTB system. The VTB system upgrade to the 3.0 version will offer greatly increased training capability. The Night Readiness VTB meets and exceeds all F-15E NVG training requirements and would represent a badly needed improvement to training in a hazardous flight regime (night, low altitude training). The VTB system was developed as a prototype from USAF and USN funded research and development to create high quality NVG classroom training. Version 2.0 has been used to train USAF air crew for nearly 4 years. Night Readiness is a primary research contractor with AFRL and is the only company with this proven NVG virtual technology. Award to any other source would result in unnecessary delays and extra and the duplication of these costs is not expected to be recovered through full and open competition. The VTB 3.0 hardware and software completely replaces the VTB 2.0 hardware and software.
