Petty Officer (Under Water) John Holah is Iron Duke’s onboard anti-submarine warfare director, he said, “Conducting exercises of this nature is always a great experience, we are a swept up team so getting to test our skills and knowledge against a real life submarine is fantastic.”

“Operating with other navies can always be a bit tricky at first until you get a clear idea of how they function but this period has been really good for us to learn how best to work together.”

Under the command of a Spanish Rear Admiral, SNMG1 has several exercises coming up in both the North Sea and Baltic region before Iron Duke returns to the UK in the summer.
