SUPERSEDING
MIL-STD-1760D
1 August 2003
DEPARTMENT OF DEFENSE
INTERFACE STANDARD
AIRCRAFT/STORE ELECTRICAL
INTERCONNECTION SYSTEM
AMSC: N/A
DISTRIBUTION STATEMENT A. Approved for public release; distribution is unlimited.
AREA: SESS
MIL-STD-1760E
FOREWORD
1. This standard is approved for use by all Departments and Agencies of the Department of Defense.
2. Prior to this standard, an aircraft and the stores which it carried were typically developed
independently of each other or were developed exclusively for each other. This usually resulted in unique
aircraft/store electrical interconnection requirements, the general proliferation of overall store interface
designs, low levels of interoperability, and costly aircraft modifications to achieve required store utilization
flexibility. Trends in store technology toward more complex store functions which require increasing
amounts of avionics data and control information from aircraft systems were predicted to lead to
insurmountable aircraft/store interfacing problems.
3. The goal is to develop aircraft that are compatible with a wide variety of stores and stores that are
compatible with a wide variety of aircraft. This standard supports this goal by defining a standard
electrical (and fiber optic) interconnection system for aircraft and stores. This interconnection system is
based on use of a standard connector, a standard signal set and a standard serial digital data interface
for control, monitor, and release of stores. Application of this standard to new and existing aircraft and
new stores will significantly reduce and stabilize the number and variety of signals required at
aircraft/store interfaces, minimize the impact of new stores on future stores management systems, and
increase store interoperability among the services, within NATO, and with other allies.
4. Revision E does not change the fundamental MIL-STD-1760 interface. It includes newly defined
requirements for a Fibre Channel interface, splits APPENDIX B into two parts, and makes other minor
changes and corrections.
5. Changes between Revision D and Revision E are not marked in this document, but note references
are added in the text, referring to notes in APPENDIX E that explain the significant technical changes.
6. Some requirements in MIL-STD-1760 are stated by invoking other documents, including MIL-STD-
1553 and MIL-DTL-38999. If tiering of requirements is limited to one level on a particular contract, it may
be necessary to include references to these second tier documents in the contractual specification.
7. The following areas are limitations of this standard:
a. Requirements for mechanical, aerodynamic, logistic, and operational compatibility are not
covered.
b. Since factors such as size, shape, loads, clearances, and functional limitations are not specified,
full operability of stores on aircraft cannot be assured.
c. Signals for emergency jettison of stores are not specified. However, this does not preclude the
use of the signals in this standard if they are compatible with the requirements for emergency jettison.
d. This standard does not attempt to establish the EMI/EMC requirements on the aircraft or store,
although it does define an interface that is generally capable of meeting these requirements.
8. Comments, suggestions, or questions on this document should be addressed to: ASC/ENOI,
2530 Loop Road West, Wright-Patterson
