More than 50 nations have signed up to French President Emmanuel Macron's call for international collaboration on cybersecurity. However, the Paris Call for Trust and Security in Cyberspace, as it is now known, is not legally binding. We ask defence and security experts what the initiative can achieve, and whether a global, coordinated effort on cybersecurity makes sense.

We also investigate potential weaknesses in the F-35’s external support systems that could leave the fighter vulnerable to hacking, check in on the latest progress of the French-German joint fighter jet development programme, and find out how Dstl is using artificial intelligence to gather accurate, real-time information on hostile radars.

NATO is facing challenges with troop mobility in Europe – an issue that has been under the spotlight since Russia seized Ukrainian territory in 2014. We find out how new software is intended to help with the logistics of moving equipment across borders, different terrains and national infrastructures more quickly and efficiently.
