This instruction implements AFPD 14-1, "Air Force Intelligence Planning and Operations", by providing guidance in identifying and acquiring intelligence to support the Air Force requirements and acquisition process, including technology efforts and Advanced Concept Technology Demonstrations (ACTDs). This AFI applies to all Air Force organizations and covers support beginning with Pre-Milestone 0 (pre-MS 0) and continuing throughout the life cycle of a program, from identification of need through development, acquisition, testing, operational employment, and sustainment and modification. This instruction supports Defense Intelligence Agency (DIA) Regulation 55-3, "Intelligence Support for Defense Acquisition Programs", March 30, 1992; DoD 5000.2-R "Mandatory Procedures for Major Defense Acquisition Programs (MDAPs) and Major Automated Information Systems (MAIS) Acquisition Programs", March 15, 1996, with Change 1; Air Force Policy Directive (AFPD) 10-6, "Mission Needs and Operational Requirements"; AFPD 10-14, "Modernization Planning"; AFPD 62-2, "System Survivability"; AFPD 63-1, "Acquisition System"; and AFPD 99-1, "Test and Evaluation Process". Attachment 1 lists the references, abbreviations, acronyms, and terms used. This document is substantially revised and must be completely reviewed. This issuance aligns duties for developing Intelligence Support Plans (ISPs). Duties that were previously assigned to HQ USAF/INXXA have been reassigned to the HQ 497 IG. It specifies the essential responsibility of operating commands to define operational requirements of specific weapon systems, and of implementing commands to define acquisition and sustainment requirements. It also specifies that weapon system planning and cost analyses include/consider the cost of unique intelligence support throughout the system lifecycle. Additionally, this revision reflects changes in the production, review, and approval of System Threat Assessment Reports (STARs) and their impact on roles and responsibilities of HQ 497 IG and other organizations providing threat support to weapon systems acquisition. An expanded role of the Threat Steering Group (TSG) is also outlined. This publication is available digitally on the SAF/AAD WWW site at: http://afpubs.hq.af.mil.
