The latest update is that we will have 3 RN ships in theatre, 2 X T23, 1 X T45. Excellent surface, sub surface and AAW capabilities. What should happen is this:
The Iranians should be told that if they attempt to block Hormuz, their coastal oil installations including Kharg Island and their off shore units will be destroyed without prior warning by the navy. Well up to the job. If we take out their oil infrastructure then they are screwed for years and the regime will collapse.
