MIL-STD-1760
MIL-STD-1760 Aircraft/Store Electrical Interconnection System defines a standardized electrical interface between a military aircraft and its carriage stores. Carriage stores range from weapons, such as GBU-31 JDAM; air-to-air missiles, such as Bozdoğan; pods, such as AN/AAQ-14 LANTIRN; to drop tanks. Prior to adoption and widespread use of MIL-STD-1760, new store types were added to aircraft using dissimilar, proprietary interfaces. This greatly complicated the aircraft equipment used to control and monitor the store while it was attached to the aircraft: the stores management system, or SMS.
MIL-STD-1760 defines the electrical characteristics of the signals at the interface, as well as the connector and pin assignments of all of the signals used in the interface. The connectors are designed for quick and reliable release of the store from the aircraft. Weapon stores are typically released only when the aircraft is attacking a target, under command of signals generated by the SMS. All types of stores may be released during jettison, which is a non-offensive release that can be used, for example, to lighten the weight of the aircraft during an emergency.
