It's been a busy September for us here at GDT with the defence industry gathering at DSEI for the 20th time. At the event we heard from military leaders and defence companies about future capabilities, including the First Sea Lord's top five priorities for the Royal Navy. You can read all about it, as well as our tour of the HMS Argyll, in this issue.

We also discuss the benefits of tracks vs wheels in the latest generation of armoured fighting vehicles, explain the Royal Navy’s role in protecting UK shipping in the Persian Gulf, and take a look at the Red Arrows' first tour of North America in 11 years.

Plus, we speak to SAP NS2 about the emerging arms race in the cyber domain, check in on the ongoing debate surrounding civil rights vs national security interests in the use of live facial recognition technology, and check out futuristic ideas for the Royal Marines.
