There are currently international Hydra suites in the U.S.A. Canada, Australia and Ireland. All of these suites deliver their own bespoke exercises. For example, the LAPD suite run Counter-terrorism exercises, and the suite in New South Wales run a pandemic exercise. In line with standard Hydra practice, the international suites also build on the knowledge and experience of colleagues across the globe.

With the advent of Hydra in the Cloud, the possibilities for further linking up these multiple sites are exciting: For example, a Hydra exercise could begin in one suite in London, the storyline could then move to Ireland, then America, and could finish in Australia.
