C5 Rapid access to solutions across multiple technology domains
Formed in 2014, C5 advances capabilities in C4ISR, cybersecurity, software, AI, enterprise networks, space systems, data analytics, MS&T, and autonomy.
Why C5
C5’s Two OTAs
C5 holds two separate OTAs. One is sponsored by Army Program Executive Office for Intelligence, Electronic Warfare and Sensors (PEO IEW&S). The other is sponsored by Marine Corps Systems Command (MCSC). While both OTAs are with the same consortium, the terms, processes, timelines, and features differ so project sponsors can select the best path for their project.

Key Distinctions Between the MCSC and Army OTAs with C5
The MCSC structured its OTA to serve as a DoD-wide acquisition resource and open-access contracting tool. No other OTA sponsored by the DoD has this unique capability. The MCSC OTA includes a mechanism that enables decentralized ordering, thereby making it available for use across the DoD and Intelligence Community.
This doesn’t mean that DoD project sponsors send their requirements and funding to the MCSC. Instead, the MCSC effectively sends its OTA to the contracting organization that directly supports the project sponsor so that they can make their own project awards using the MCSC OTA. This results in project award timelines that are up to 75% less than the award timelines of other DoD OTAs.
MCSC OTA Features
In addition to decentralized ordering, the MCSC OTA has the following features:
CMG Networks Consortium Opportunities
CMG Networks consortia feature a continuous stream of project opportunities. Throughout the year, Government program sponsors develop project requirements and issue project solicitations through our CMG Networks to our members. Our team assists interested member companies in the development of their responses.
