# Military Programs Adopt Open Architectures

At the September 2026 MOSA Summit, government officials highlighted plans to apply modular open systems approaches to space systems, collaborative combat aircraft, and weapons programs, and announced formation of a MOSA Cadre to help programs implement modularity. Contractors can use the SOSA Space Appendix and government reference architectures available through the Open Arsenal Portal to assess how their systems align. The signal identifies no specific solicitation, contract value, or procurement contact.

- The MOSA Cadre and reference architectures give acquisition teams and contractors a basis for incorporating open-system design into relevant programs; companies should assess their offerings against the cited architectures.
- The focus spans space, collaborative combat aircraft, and weapons programs, creating potential relevance for suppliers of modular embedded systems and interoperable components.
- No named solicitation or award is identified, so the signal points to an acquisition direction rather than a currently defined bidding opportunity.
