\n\nDescription
\n\nSSC 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:
\n\nContract Type
\n\nThe 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.
\n\nSmall Business Consideration
\n\nThe North American Industry Classification System (NAICS) code for this effort is 541715 -
\n\nResearch and Development in the Physical, Engineering, and Life Sciences (except
\n\nNanotechnology and Biotechnology). The small business size standard is 1,000 employees.
\n\nParticipation from small and small disadvantaged businesses is encouraged. SSC's Small
\n\nBusiness points of contact can be reached at smallbus@spaceforce.mil or by phone at (310) 653-1108.
\n\nSmall Business Opportunities
\n\nThe government would like to encourage small business participation in the performance of this effort and requests insight into how your company would incentivize Small Business participation.
