Various systems and methods for leveraging legacy countermeasure dispensing systems (CMDSs). The legacy CMDSs are leveraged through the expansion of breechplates and magazines in a CMDS by expanding the amount of expendables carried by a CMDS while still maintaining the legacy sequencer and dispenser in a legacy military platform, such as an aircraft. In addition, various circuitry systems are included in a circuit card of the breechplate for duplicating and/or expanding the firing lines provided in a legacy CMDS.

A countermeasure dispenser system has a dispenser with a fire pin and a smart expendable housed in the dispenser awaiting to be fired upon a fire command. The smart expendable has features that need power and communication signals from the dispenser. The communication signals and power sent from the dispenser to the smart expendable are sent through an interface that is different than the fire pin in the dispenser. The interface may be a dedicated wired interface or the interface may be a wireless interface. If wireless, the wireless interface may use near field communications, RF signaling, or near field magnetic induction.
