Justification Review Document Summary

This is a Justification Review Document for a sole-source procurement by the National Guard Bureau (Arlington, VA) for the KG-175F Bandwidth Upgrade. The contract action is a new firm fixed-price contract valued at an undisclosed estimated price, with the requiring activity identified as 152 ACOMS and the point of contact redacted. The procurement is authorized under 10 USC 3204(a)(1) or 41 USC 3304(a)(1) as implemented in FAR 6.302-1, which permits sole-source acquisitions when only one responsible source and no other supplies or services will satisfy agency requirements. The contract type is firm fixed-price with O&M (Operations & Maintenance) funding classification under the Air Fund.

The requirement is for Bandwidth Expansion Software (1 Gb/s) to upgrade the encryption device already integrated into the National Guard Bureau's current infrastructure. The justification demonstrates that General Dynamics Mission Systems, Inc. is the sole authorized source as the certified Type 1 Encryptor Product Line manufacturer, distributor, and owner of the proprietary KG-175F device. The specific TACLANE product family (including models KG-235, KG-175, KG-175A, KG-175B, KG-175D, KG-175F, KG-175G, KG-175X, KG-175N, and C175N) is required for communications security. A sources sought notice was issued on March 17, 2026, yielding only one response from General Dynamics. Market research confirmed no alternative vendors provide compatible systems. The document was dated September 8, 2025, with approvals from Configuration Manager and Contracting Officer Briana McCaffery on April 1, 2026.
