Australia’s maritime estate is simply too vast for any conventionally manned fleet to patrol effectively – uncrewed and autonomous systems will prove key to maintaining Australia’s maritime sovereignty.
With an exclusive economic zone stretching across roughly 8.2 million square kilometres and critical northern chokepoints through which virtually all the nation’s fuel and essential imports flow, the conversation establishes from the outset that the case for autonomous maritime systems isn’t about technological novelty, it’s about geographic necessity.
In this episode of the Defence Connect Spotlight podcast, host Steve Kuper speaks with Elysium EPL director Michael “Mitch” Mitchell where they discuss the increasing proliferation of autonomous and uncrewed systems with the Royal Australian Navy.
Drawing on his experience as a submariner, Mitchell’s first and most important argument is the persistence imperative. Manned patrol vessels, however capable, are constrained by crew welfare, logistics and port rotations. Autonomous platforms carry none of that overhead. They can loiter on station for days or weeks, consuming far fewer resources and requiring only remote oversight.
His second key argument is a conceptual reframe: stop thinking about platforms and start thinking about payloads. The hull, in Mitchell’s framework, is just a delivery mechanism. What matters is the modularity of what it carries – sonar, radar, sonobuoys, acoustic modems, hydrographic sensors – and whether those payloads can be swapped rapidly to meet different mission requirements.
They also discuss Elysium EPL’s dual-use certification approach, deliberately avoiding ITAR-restricted components, which is presented as proof of concept for this philosophy in practice.
Perhaps the most culturally challenging argument Mitchell makes concerns attritability. Australian defence procurement culture treats assets as things to be preserved.
Mitchell argues that small autonomous vessels need to be reconceptualised as expendable ordnance, drawing an explicit parallel with the Nulka active missile decoy deployed in numbers and postures that would be unthinkable for crewed platforms.
