Diving unit’s story revealed

A new book, to be launched later this month, The Ninth Ship — The Irish Naval Diving Section, outlines a history of divers’ operations.
In 1964, a young Lt Joe Deasy received notification from headquarters he was being sent to England to commence a seven-month long torpedo anti-submarine course, known as the TAS course. It came as a complete surprise to the officer because he never expressed anything remotely resembling a desire to go diving.
