This is a Request for Information (RFI) for future Operation and Maintenance support services for threat systems used in Electronic Warfare and Cyberspace Operations training and testing. The work involves providing realistic threat emulation, including jamming and cyber Red Teaming, in a "free play" environment at locations such as Combat Training Centers and White Sands Missile Range, New Mexico. The government is seeking information on vendor capabilities and encourages responses from companies interested in teaming as either a prime or subcontractor. Respondents must have a Top-Secret facility clearance. No budget, specific timelines for performance, or a formal solicitation are associated with this RFI.
