What this publication covers

This instruction defines the USSF system acceptance process necessary to ensure new systems meet operational and institutional requirements, and have the necessary elements required to support mission execution. System acceptance is implemented through a thorough and scalable process to deliver essential space warfighting capabilities to the war fighter in accordance with (IAW) Chief of Space Operations (CSO) strategic objectives. System includes, but is not limited to, a weapon system intended for operational employment as part of the joint force, institutional capabilities, service-retained capabilities, software, permanent modifications to existing systems, training systems, and test and evaluation systems.
