DARPA posts updated STO BAA

On October 21, the Defense Advanced Research Projects Agency (DARPA) updated its Strategic Technology Office (STO) broad agency announcement (BAA). The closing date is November 14, 2025.

Proposed research should investigate innovative approaches that enable revolutionary advances in science, devices, or systems. DARPA anticipates funding a limited number of proposals under this solicitation. Specifically excluded is research that primarily results in evolutionary improvements to the existing state of practice.

The STO at DARPA regularly publishes BAAs requesting responses to specific program topics. This announcement seeks revolutionary research ideas for topics not addressed by ongoing STO programs or other published BAA solicitations.

DARPA’s STO is seeking innovative ideas and disruptive technologies that provide the U.S. military and national security leaders with trusted, disruptive capabilities across all physical domains (Air, Space, Sea, and Land) and spectrum of competition. STO programs deliver solutions at speed and scale for today’s warfighters while developing the resilient “breakthrough” systems and technologies needed for future battlespaces. STO does not focus on one area of responsibility or phenomenology. Rather, STO programs capture the strategic, logistical, and tactical complexity of today’s national security environments.

STO is a “systems office” seeking to create new “proof-of-concept” mission systems. Its goals are to develop and demonstrate new capabilities that expand what is technically possible.
