About this file
This document is a Request for Information (RFI) detailing technical requirements for a C-17 Databus Recording System (DBRS). The RFI outlines specific minimum technical requirements and technical tradeoff parameters for a Line Replaceable Unit (LRU) designed to record aircraft data. Key technical specifications include the ability to simultaneously record data from multiple bus types (9 MIL-STD-1553 dual-channel buses, 8 ARINC 429 buses, and 2 EIA-422 buses), store data on a removable solid-state device, operate on 28 VDC power, perform cryptographic operations, and mount securely in a C-17 avionics rack.
The document is marked as Controlled Unclassified Information (CUI) and is distribution-restricted to Department of Defense and U.S. DoD contractors. The associated federal contract opportunity (Solicitation Number FA8526-24-R-DR) is a pre-solicitation Sources Sought Synopsis aimed at identifying potential sources capable of developing a databus recorder system for the C-17 Globemaster III aircraft. The Air Force Materiel Command Lifecycle Management Center at Robins Air Force Base is seeking a hardware solution that can capture data across all aircraft buses while complying with current Air Force cybersecurity standards. Notably, the government will not reimburse participants for expenses related to this sources sought synopsis, and participation does not guarantee future solicitation or contract awards.
