1.0 Introduction and Purpose The Department of the Air Force (DAF) is conducting market research to identify parties with the requisite capabilities, resources, and experience to provide comprehensive product support and sustainment integration for the Air Base Air Defense for Missile Defense (ABAD MD) System. This RFI is issued solely for information and planning purposes and does not constitute a Request for Proposal (RFP) or a promise to issue an RFP in the future. This request for information does not commit the Government to contract for any supply or service whatsoever. 2.0 Background and Operational Posture The ABAD MD system is a critical, actively deployed capability for air base defense. The program is executing Phase 5, which focuses on the sustainment of currently fielded systems operating in active defense postures. Leveraging Tactical Operations Center – Light (TOC-L) hardware, these Command and Control (C2) systems are deployed in support of immediate warfighter operations. Historically, this system has relied on proprietary Original Equipment Manufacturer (OEM) software. The Government's objective for the next phase of this program is twofold: Maintain strict, uninterrupted operational readiness and cybersecurity posture for the actively fielded legacy baseline. Execute a deliberate, phased modernization effort to replace proprietary components with open-standard, non-proprietary software, eliminating vendor lock without degrading current capabilities. 3.0 Scope of Work and Phased Approach The contractor shall be responsible for activities ensuring successful continuous sustainment and modernization of the ABAD MD system. The Government anticipates the following: Core Sustainment Operations: Full assumption of ABAD MD and TOC-L Product Support Hubs, Tier I-III help desk operations, provision of cleared Field Service Representatives (FSRs) to active sites, and routine cybersecurity patching/Information Assurance Vulnerability Alerts (IAVAs). 4.0 System Constraints and Available GFI/GFP The ABAD MD system's current operational baseline relies on integrated software components proprietary to Lockheed Martin. The Government does not possess source code for these specific components: UCI Blaster: Universal Command and Control Interface (UCI) formatting/routing software. PIPES: UCI Message translation utility. UCI Blaster Manager: Management interface for UCI routing. NKE Emulator: System emulation capability. Screen Watchdog / BIF Hub: System monitoring and screen recording functionalities. 4.1 Available Government Furnished Information/Property (GFI/GFP): To facilitate a competitive transition and support the OSA migration, the Government intends to provide the awardee with: System Interface Control Documents (ICDs) defining the inputs/outputs of the proprietary components listed above. Full access to ABAD MD TOC-L hardware baselines and software test-beds (SIL/ITF). The existing Risk Management Framework (RMF) …
