The US and her allies are embracing the Multi-Domain Operations philosophy with the Joint All Domain Command and Control System is at the heart of this endeavour. Multi-Domain Operations, or MDO, focus on improving the pace and quality of decision-making at the expense of one’s adversary. The goal is to navigate the famed OODA (Observe, Orient, Decide and Act) loop at a faster clip than your enemy. Get MDO right and you will always be proactive while your opponent is forced to be reactive. JADC2 The Joint All Domain Command and Control architecture, or JADC2, is the US Department of Defence’s networking and computing project that will enable MDO. JADC2 will see the inter- and intra-force connection of all personnel, weapons, sensors, platforms, subsystems and capabilities at all levels of war. The undertaking is ambitious. Reports say that since 2022 the Pentagon has spent up to $2.6 billion on JADC2. A further $9 billion could be spent on the initiative before the end of the decade. In episode 15 of Armada’s Radioflash! podcast we talk to Leslie Hulser, executive vice president, corporate strategy of Persistent Systems. We examine the status of JADC2, what this overarching effort has achieved to date, potential problems and shortcomings, and the work that still needs to be performed.
