Small Unmanned Aerial Systems Charging Connector/Interface

The C5ISR Center Power Division is issuing a sources-sought notice, solicitation number W56KGU27R1001, to gather information on current product offerings for a standard small Unmanned Aerial Systems (sUAS) charging connector and interface. This initiative targets Group 1 and Group 2 UAS to establish a common standard for the interface between batteries and chargers, aiming to improve interoperability and reduce the logistical and cognitive burden on warfighters. The effort is managed by the Department of Defense through the W6QK Acc-Apg office located at Aberdeen Proving Ground, Maryland. Interested respondents must submit detailed information packages by November 20, 2026, including mechanical specifications with CAD drawings, electrical details such as voltage and power ranges with pin-out descriptions, and data communication protocols between the Battery Management System and the charger. The government is also seeking information regarding MIL-STD-810 environmental testing, water ingress protection, and the costs associated with obtaining unlimited government data rights. This RFI is being used to determine whether a future contract will be conducted as a full and open competition or as a set-aside for small businesses and other specific designations such as SDVOSB, HUBZone, or 8(a).
