Storage Maintenance—This requirement includes: maintain-in, represervation, and other
miscellaneous requirements for most AF owned assets that are not part of a MAJCOM's active
inventory. The PM involved funds input to and removal from storage.
Supportability—The degree to which the planned logistics support allows the system to meet its
availability and wartime usage requirements. Planned logistics support includes the following:
test, measurement, and diagnostic equipment; spare and repair parts; technical data; support
facilities; transportation requirements; training; manpower; and software.
Supported Command—AF Organizations that share a system with a lead command, other AF
organizations, units of the AFRC, or the NGB.
Sustaining Engineering (SE)—Technical tasks to ensure continued operation and maintenance
of a system with managed known risk. SE involves the identification, review, assessment, and
resolution of deficiencies throughout a system's life cycle. SE both returns a system to its
baselined configuration and capability, and identifies opportunities for performance and
capability enhancement. It includes the measurement, identification and verification of system
technical and supportability deficiencies, associated root cause analyses, evaluation of the
potential for deficiency correction and the development of a range of corrective action options.
Sustainment—The continuing materiel support which consists of the planning, programming,
and execution of a logistics support strategy for a system, subsystem, or major end item to
maintain operational capabilities from system fielding through disposal.
Tactical Missiles—The requirement consists of hardware repair and testing of whole missiles
captured under EEIC 542, missile components and containers captured under EEIC 545 that are
not the responsibility of CSAG-S, or missile support equipment which is usually captured under
EEIC 545, but may also be EEIC 544. This also includes changes to operational NSS captured
under EEIC 540, if the missile or support equipment is programmable. It includes changes to
operational UUT TPSs, when the UUT is not the responsibility of CSAG-S. Guided Bomb Units-
15 component items are also included.
Technical Data—A general term used when referring to any or all technical publications as a
whole or separately, and without reference to any one specific type of publication, such as
technical manuals, technical orders, composition, artwork, engineering data, engineering
drawings, master layout drawing, un-dimensioned drawings, specifications, parts list, automatic
equipment program master tapes or cards, microfilm, printed copies, commercial manuals, film,
sound tracks, or any other media used primarily for conveying technical information. The term
technical data also applies to the reproducible copy from which multiple copies of technical data
are reproduced.
Technical Order (TO)—A publication that gives specific technical directions and information
in regards to: inspections, storage, operations, modifications, and maintenance of AF equipment.
The various types of technical orders include technical manuals, TCTOs, methods and
procedures technical orders, automation type TOs (e.g., tapes and cards that are TO data in
digital, magnetic, film, or sound form), index type TOs, and abbreviated TOs.
Then Year—Refers to obligations (or dollars which will be spent over time).
Timely—Individual tasks identified at the appropriate time to support the requirements
development process schedule.
