SFL Missions designs small-satellite buses and delivers mission integration, launch and operations support. Its SPARTAN platform underpins AISSat-4 maritime tracking, and DEFIANT units support HawkEye 360 RF-geolocation spacecraft through customer integration. DAUNTLESS-L is the basis of a separate Moonraker lunar spacecraft concept at Phase A.

These describe the reviewed application scope, not confirmed deployments, released requirements or procurement eligibility.
Evidence of maturity
AISSat-4 and Cluster 14 launched in March 2026. HawkEye 360 reported Cluster 14 operational in June. Moonraker remains a spacecraft and mission feasibility study.
Commercial availability
SFL offers complete mission delivery and Flex Production arrangements; the division of manufacturing and integration responsibility is negotiated with each customer.
