DARPA has developed a prototype unmanned submarine hunter which it claims could lead to an entirely new class of military vessels, autonomously patrolling the seas for months on end at a fraction of current costs. We find out what that means for submarine warfare as we know it.

We also take a look inside the Northrop Grumman / Orbital ATK deal and ask what it will mean for the defence industry, speak to Hewlett Packard about the capabilities of its new supercomputers for the US Air Force Research Laboratory at Wright-Patterson Air Force Base, and look at the latest innovations in military aircraft.

Plus, we ask whether Canada’s choice of ultra-light combat vehicles from Polaris Industries could set a trend in light options that other countries may follow, and check in on the latest developments in night vision technology.
