Cornerstone OTA CS-26-1501 40mm Counter Unmanned Aerial System (CUAS)

The Department of Defense, through the U.S. Army Combat Capabilities Development Command – Chemical Biological Center (DEVCOM CBC), is initiating a competitive Cornerstone Initiative Request (CIR) for the development of a 40mm Counter Unmanned Aerial System (CUAS). The objective is to integrate advanced proximity sensing fuze technology into programmable air burst cartridges for the MK19 grenade launcher, creating a comprehensive system for countering small UAS threats, which includes detection, tracking, targeting, and defeat functionalities. This initiative is crucial for enhancing the U.S. Manufacturing and Defense Industrial Base, and interested parties must be members of the Cornerstone consortium to participate, with a proposal submission deadline expected 30 days after the CIR issuance on or after November 25, 2025. For inquiries and registration information, interested entities should contact the Cornerstone OTA mailbox at usarmy.ria.devcom-cbc.mbx.cornerstone-ota@army.mil.
