Amendment #10: Common Very Low Frequency Receiver (VLF) Increment 2 (CVRi2) Modernization

The Air Force’s VLF Enterprise Program Office is seeking qualified firms to design and develop a common, production‑ready Very Low Frequency (VLF) receiver system (CVRi2) that will replace legacy airborne and ground‑based VLF NC3 equipment across all conflict levels. The effort includes delivering the receiver hardware, associated ancillary equipment, and implementing a Crypto Modernization‑2 (CM2) compliant, New Waveform capable, NSA‑certified solution that integrates with Open Mission Systems (OMS). The contract will be awarded under an existing AFLCMC/XA IDIQ Category 2 vehicle, with a single or two delivery orders anticipated, subject to funding availability.
