SYSTEM DELTA 84 (SYD 84/MT) MEDIUM EARTH ORBIT MISSILE WARNING / MISSILE TRACKING EPOCH 3 and EPOCH 4, REQUEST FOR INFORMATION (RFI)

SPACE SYSTEMS COMMAND (SSC)

System Delta 84 (SYD 84/MT)

MEDIUM EARTH ORBIT MISSILE WARNING / MISSILE TRACKING

EPOCH 3 and EPOCH 4

Description 

SSC requests industry feedback on a Resilient Missile Warning and Tracking (MWT) Medium Earth Orbit (MEO) layer Epochs 3 & 4 (E3&4) production feasibility that will support MWT Full Warfighting Capabilities (FWC). The government is seeking industry feedback to inform the MEO E3&4 acquisition strategy and technical approach. The MEO MWT architecture is being incrementally developed in capability-based deliveries called Epochs. Each Epoch is expected to include at least one competitive award and allows for insertion of new technology and innovative solutions in response to progressive or updated warfighter requirements to ultimately meet Overhead Persistent Infrared (OPIR) capability needs. This RFI requests industry feedback and approaches to support delivering a MEO MWT E3&4 capability. The government encourages capability providers to offer responses for individual or multiple elements of the system architecture:

• Epochs 3 & 4 Space Vehicles (E3&4 SVs) - delivery, integration, and operations
• MEO Ground - ground segment with facilities and sites to operate the entire MEO MWT constellation with respect to Command and Control (C2)
• Digital Engineering Integration in alignment with Government Digital Engineering vision

Contract Type  

The government is intending to use only Firm Fixed Price (FFP) contract type with an Other Transaction Authority (OTA) agreement. Feedback on this approach is welcome.
