The importance of increased collaboration and cooperation between our three highly capable and like-minded services can't be overstated.

As part of the exercises, Izumo and Argyll both deployed helicopters to hunt the submarine.

The Type 23's Wildcat was loaded with a Test Variant Torpedo (TVT) by 208 Flight before launching off Argyll's deck to step up the search for the US submarine.

The Japanese also sent up their anti-submarine Seahawk helicopters alongside a Maritime Patrol Aircraft.

"Given the increase in maritime traffic worldwide and current events, the importance of increased collaboration and cooperation between our three highly capable and like-minded services can't be overstated,” said Captain Katsuyoshi Motoyama, Commander of Izumo.

"We all share a common vision of enhancing the operational effectiveness of our maritime forces."

Argyll is currently on a nine-month deployment and following these exercises came alongside at US Naval Base in Yokosuka, Japan.

After operations during the Christmas period, this was a chance for the ship’s company to explore capital Tokyo and head into the surrounding mountains above Yokosuka to take part in winter sports.
