The mother ship HMS Cornwall a frigate and the small vessel had GPS linked to each other so both knew where they were.

The lady is a lawyer I believe.

The Brits were patrolling the same area as the US and Australia has been for that past several years and if the Iranian's wanted to just get along they never would have acted this way.

Iran is trying to show the world it can do what it wants when it wants and probably retaliation from the sanctions and the defection/capture of Iranian General Asgari.

You can bet any body on patrol in the same waters will have helicopter support from now on.
