FOREWORD
General military specifications and military standards are
top-level
standardization documents.
They are prepared in
accordance with
directives to establish a formal corporate
memory of good practices and requirements.
In some cases they
are referenced in government regulations to impose internal
compliance on government organizations.
More
typically, these
standardization documents are intended for reference in
contracts as compliance documents for imposing the good
practices and other stated requirements on
c o n t r a c t o r s .
Although these roles are broad, many facet6 of engineering
technical data that are important to program success are not
appropriate for inclusion in these formal
standardization
documents.
These added facets of information may be documented
in technical reports
or,
a6 in this case, in military handbooks.
This military handbook is intended to document additional
facets of engineering technical information pertinent to the
requirements stated in

Requirement6 for
Space Vehicles.
As a technical reference, this handbook should
provide the basis for achieving a consistent technical approach
for tailoring MIL-STD-154OB requirements, where appropriate, and
may also provide the bases to justify deviations or alternative
approaches where they are appropriate.
Each major subsection of
this handbook addresses a subject taken from MIL-STD-15408.
Remember that the information included herein is for general
guidance; it need not be followed if it doe6 not accommodate the
requirements of the program.
In the case of difference6 between
this handbook and the requirements of

Section 2, Referenced Documents, and Section 3, Definitions.

MIL-STD-1540B are often linked and discussed in one major
section or subsection of this handbook.
