Marcus and Michael get serious about biofuel, with a novel feedstock straight from Defence’s Russell Offices HQ. They look at the rapidly expanding Iran War, with multiple US partners being pulled into a messy patchwork, all desperately trying to quarantine their roles into a defensive effort. They explain the Australian policy to ensure no ADF personnel are involved in attacking Iran, even when they are (hint: closing eyes at critical moments helps).

The missile supply issues have intensified, with US production being diverted to the war and other forces’ orders being delayed – probably by years. Despite the war apparently being way ahead of schedule, Iran’s attacks are continuing, Israel is evacuating citizens away from Hezbollah drones, and US diplomats are leaving Saudi and Turkey.

The episode ends with a capability roundup for Australia – pricey Peregrines, artisanal K-9s, maritime precinct sketches and broken submarines.
