The first was a passenger liner completed in 1909 that, in 1914, became the armed merchant cruiser HMS Otranto and, in 1918, was lost as a result of a collision.

56 corrugated furnaces with a combined grate surface area of 2,688 square feet (250 m2) heated her boilers.

Otranto accidentally collided with the Japanese steamer Kitano Maru[4] in August 1928, heavily damaging her.

In May 1932 she played a small part in the rescue of the passengers and crew of the French ocean liner Georges Philippar in the Gulf of Aden.

In February 1957 she made her final voyage, from the UK to Sydney, Australia via Cape Town, South Africa.
