Common Very Low Frequency Receiver (VLF) Increment 2 (CVRi2) Modernization: - AFNWC/NC3's VLF Enterprise Program Office (EPO) is soliciting proposals from Industry for the design of a "common" advanced VLF (e.g., secure Beyond Line of Site comms of Emergency Action Messages thru all levels of conflict) capability that will modernize all legacy VLF NC3 airborne and ground-based VLF systems and equip future NC3 platforms with a Crypto Modernization-2 (CM2) compliant, New Waveform capable, NSA certified, and Open Mission Systems (OMS) capable "common, one-size-fits all" receiver system. The objective of this program is the rapid development of a production-ready, fully functional very low frequency receiver and its required ancillary support equipment. This Fair Opportunity Proposal Request (FOPR) outlines the requirements for the submission of proposals for the Common Very Low Frequency Receiver Increment 2 (CVRi2) Program. The Government intends to award to one or two Delivery Orders (DOs) based on best-value determination and the availability of funding. This competitive action is conducted in accordance with Revolutionary FAR Overhaul (RFO) 16.507.
