Cathode Advancements in Science and Technology for Oxygen Resistance (CASTOR)

The Defense Advanced Research Projects Agency (DARPA) Defense Sciences Office (DSO) is issuing a Disruption Opportunity (DO), inviting submissions of innovative basic or applied research for efficient, high-performance, long-lived oxygen-compatible cathodes for use in air-breathing very low earth orbit (VLEO) electric propulsion (EP) systems. This DO is issued under the Program Announcement for Disruptioneering, DARPA-PA-25-07. All awards will be made in the form of an Other Transaction (OT) for Prototype project.

The total award value for the combined Phase 1 base (Feasibility Study) and Phase 2 option (Proof of Concept) is limited to $900,000 (see Section I.C for information more information on phase structure). This total award value includes Government funding and performer cost share if required or proposed.
