The Naval Air Warfare Center Training Systems Division intends to award a sole-source contract to General Dynamics Mission Systems (GDMS) for Bridge Part Task Trainer (BPTT) Port Databases, as GDMS is the original equipment manufacturer and sole provider of the Virtual Ship (VShip) licenses. The requirement covers procuring, delivering, testing, and correcting deficiencies for export-control-compliant VShip harbor databases and electronic charts for multiple ports, including Jubayl, Gibraltar, Gulf of Aden, Rota, Souda Bay, Naples, Jizan, Dammam, Jebal Ali, Abu Dhabi, Bahrain, Djibouti, Doha, Muscat, Port Everglades, Port Canaveral, Key West, Salalah, Fujairah, Yokosuka, and the Oshima Strait. Performance and delivery will be at the Multi-Mission Surface Combatant (MMSC) training system in Jacksonville, Florida. The government is seeking information from potential sources to determine whether a comparable source exists and whether competition would be advantageous. This is a sources sought notice for informational purposes only and does not constitute a solicitation or request for proposals.
