Amendment #3 (28 May 2026) for the Common Very Low Frequency Receiver Increment 2 (CVRi2) Modernization Fair Opportunity Proposal Request (FOPR) has been released. This amendment updates the Bidder's Library, corrects SOW deficiencies, introduced a new contract clause, and incorporates formal responses to Industry's questions. Award eligibility remains restricted to AFLCMC/XA IDIQ Category 2 awardees. Updates...
View moreAmendment #1 (4 May 2026) for the Common Very Low Frequency Receiver (VLF) Increment 2 (CVRi2) Modernization Fair Opportunity Proposal Request (FOPR) is now available. This update incorporates supplemental language into Section 3.4.1 Volume 1 Technical – Engineering and Section 3.4.2 (Volume 1 Technical - Logistics). Please be advised that eligibility for award is strictly limited to AFLCMC/XA IDIQ Category 2 contract awardees.
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. As orders under IDIQ contracts are not source selections, DoD source selection procedures do not apply. All ordering will be conducted IAW RFO 16.507 and the AFLCMC/XA IDIQ contract ordering procedures. All offerors must be awardees under Category 2 of the referenced AFLCMC/XA IDIQ to be eligible for consideration.
No award will be made under this solicitation until funds are available. The Government reserves the right to cancel this solicitation, either before or after the closing date. In the event the Government cancels this solicitation, the Government has no obligation to reimburse an offeror for any cost.
This is the public notice of the solicitation. The solicitation package contains Controlled Unclassified Information (CUI) and access will be restricted to Offerors who are certified by the Joint Certification Program (JCP).
Offerors shall provide their CAGE Code and identify all locations where classified information will be accessed, handled, or processed prior to receipt of classified documentation. This information shall be provided to the Contracting Officer no later than 20 April 2026 at 4:00 PM Eastern Time.
The Department of the Air Force, through the AFNWC Nuclear Network Division, is soliciting proposals for the Common Very Low Frequency Receiver Increment 2 (CVRi2) Modernization program under solicitation number FA8735-26-R-B001. The VLF Enterprise Program Office is seeking the design of a common advanced very low frequency capability to modernize legacy airborne and ground-based Nuclear Command, Control, and Communications (NC3) systems. The objective is the rapid development of a production-ready, fully functional receiver system and ancillary support equipment that is Crypto Modernization-2 compliant, New Waveform capable, NSA certified, and Open Mission Systems (OMS) capable. This "one-size-fits-all" system will provide secure Beyond Line of Sight communications for Emergency Action Messages across all levels of conflict.
Performance is located at Hanscom AFB, Massachusetts, under NAICS 541715, Research and Development in the Physical, Engineering, and Life Sciences (except Nanotechnology and Biotechnology), and PSC 5821, Radio and Television Communication Equipment, Airborne. This competitive action is conducted in accordance with Revolutionary FAR Overhaul (RFO) 16.507, and eligibility for award is strictly limited to AFLCMC/XA IDIQ Category 2 contract awardees. The government intends to award one or two delivery orders based on a best-value determination and the availability of funding. No set-aside has been designated for this requirement (NONE/NONE).
The response deadline is July 8, 2026. Amendment 3, released on May 28, 2026, updated the Bidder’s Library, corrected Statement of Work deficiencies, introduced contract clause RFO 52.222-90, and incorporated formal responses to industry questions. The solicitation includes 44 attachments, such as system interface drawings, design requirements specifications, and a model contract. While unclassified documents are available for download, access to documents containing Controlled Unclassified Information is restricted to offerors certified by the Joint Certification Program.
