Design and develop a state-of-the-art (autonomous) multi-domain alert system (to include necessary indicators), as part of an improved response system (MCM-0234-2022) to inform political decision-making and enable effective military preparedness. ACO will set out the requirements for the future MDO Alert System, anticipated to be delivered by 4QR24. Then ACO will work with ACT to specify appropriate mechanisms to design and deliver such a system.
