The Defense Advanced Research Projects Agency (DARPA) is hosting an Industry Day on October 2, 2024, to discuss the Heimdall program, which aims to develop secure Artificial Intelligence and Machine Learning (AI/ML) capabilities for naval gun systems utilized by the U.S. Navy. The program focuses on enhancing the effectiveness of the Mk 160 Gun Computer System (GCS) through software updates, with a two-phase approach that includes algorithm development and final software integration for at-sea testing. Interested participants must register by September 27, 2024, using DARPA Form 104, as attendance is limited to 350 individuals, and while participation is voluntary, DARPA encourages engagement from non-traditional contractors. For further inquiries, potential proposers can contact the TTO BAA Coordinator at DARPA-SN-25-02@DARPA.MIL.
