Henrik Ekstrom is a Swedish/Swiss/Australian author residing in Sydney. His late 1990’s military service was spent as a sonar operator on board then brand new Swedish A19, Gotland-class attack submarines. The same submarine that later successfully attacked the USS Ronald Reagan Aircraft Carrier while running exercises in the Pacific Ocean. A long interest in the clearly complicated issues of the underwater territorial breaches allegedly occurring in the 1980s followed him through his career from Sweden to Switzerland to Australia before culminating in “Unbroken Silence”.
