Use/relationship:
a. An SSRA is an assessment performed by program managers (PMs) and materiel developers
(MATDEVs), which include concept developers, on all programs that are acquiring, developing,
incorporating, or modifying spectrum-dependent (S-D) systems (SDS). Its purpose is to identify
and assess an acquisition’s potential to affect the required performance of the newly acquired
SDS and other existing systems that may co-exist within the operational electromagnetic
environment (EME). Each assessment will be accomplished with due consideration given to
potential regulatory, technical, and operational spectrum and electromagnetic (EM)
environmental effects (E3) issues. All identified risks must be included in the assessment
including relevant mitigation information. Requirements for the submission of SSRAs during
the Defense Acquisition System (DAS) process, as depicted in Table I, are established by the
following:
(1) Department of Defense Instruction (DoDI) 4650.01 which requires the submission of an
SSRA prior to each acquisition milestone (MS).
(2) Chairman of the Joint Chiefs of Staff Instruction (CJCSI) 6212.01 which requires the
submission of SSRAs prior to each acquisition MS and readiness reviews.
(3) DoDI 4630.8 which requires the results of the SSRAs for information technology and
national security systems be included in the Information Support Plan (ISP).
Guidance for conducting the tasks outlined in Table I can be found in Department of Defense
Directive (DoDD) 3222.3, MIL-HDBK-237, and MIL-HDBK-235-1C and its supplemental
parts. Copies of DoD Instructions and Directives are available online at
https://www.dtic.mil/whs/directives/. CJCSI 6212.01 can be found at www.dau.mil. For copies
of the classified and limited distribution parts of MIL-HDBK-235, see the Foreword of MIL-
HDBK-235-1C.
b. This DID contains the format and content preparation instructions for data resulting from a
solicitation for the preparation of an SSRA. It is intended for SDS, including commercial items
(CIs) and non-developmental items (NDIs) that are S-D, employed on airborne, sea, space, and
ground platforms and systems.
c. SSRAs are required throughout the acquisition process as depicted in Table I. The Military
