In 1928, six British-made Hawker Horsley aircraft were delivered to the Hellenic Naval Aviation. They could carry the impressive for the time, load of a 975 kg torpedo. They were based at Tatoi, near Athens, from the beginning to the end of their service. In their final years, they were used for training purposes. They did not take part in any operation during World War II.
