Solicitation # 32000479
This design-build project involves the construction of a full motion Weapons System Trainer flight simulator facility for C-130J aircraft at USCG Base Elizabeth City, North Carolina. The approximately 13,000 gross square foot facility will include a simulator bay for a Government Furnish, Government Installed mobile simulator, classrooms, administrative offices, debriefing spaces, and essential support areas for mechanical, electrical, and telecommunications systems.
