# SNC and Skyryse Plan Aircraft Retrofits

Sierra Nevada Corporation (SNC) and Skyryse plan to integrate Skyryse’s SkyOS flight-control hardware and software into in-service aircraft, beginning with defense platforms and potentially extending to fixed- and rotary-wing fleets. The planned effort could generate requirements for aircraft integration, certification, retrofits, and modifications, but no contract award, value, solicitation number, or procurement schedule has been announced.

- SNC and Skyryse’s planned work points to potential opportunities for firms with aircraft modification, systems integration, and certification capabilities.
- Contractors can assess whether their capabilities support fixed- or rotary-wing retrofit work and potential teaming with the companies as the effort develops.
- Because the signal identifies no solicitation or schedule, there is no stated deadline or current bid action for companies to pursue.
