RMS Andes was a notable 26,689 GRT steam turbine ocean liner, serving as a Royal Mail Ship, cruise ship, and the flagship of the Royal Mail Lines fleet. Built in Belfast by Harland and Wolff between 1937 and 1939, she was launched in March 1939 and completed just before the outbreak of World War II. Designed for the UK–South America route, Andes featured a long, streamlined hull painted in traditional maritime colors, with passenger accommodations originally divided into first and second classes, totaling 607 berths. Post-war, her capacity was reduced to about 528 to accommodate more crew comfort. Her construction included advanced features for her time, such as steam turbines powered by three oil-fired water tube boilers, providing a total of 5,599 NHP and enabling her to cruise at 21 knots initially. She had extensive fuel and water capacities, allowing for long-distance voyages without resupply. Her layout incorporated five cargo holds with refrigeration and insulation for shipping perishable goods from South America, and she was equipped with navigational instruments like a semi-balanced rudder, echo sounder, wireless direction finders, and Kelvite and Husun compasses. Passenger safety was ensured with 14 lifeboats accommodating 1,174 persons, mounted on Taylor's patent gravity davits. Initially intended for civilian service, Andes was requisitioned by the Admiralty in late 1939 shortly after her completion and converted into a troopship capable of carrying around 4,000 troops. During her wartime service, she broke three long-distance speed records and participated in numerous convoy operations across the Atlantic, Indian Ocean, and Mediterranean, transporting troops and cargo including valuable cargoes like gold bars. Her wartime service was extensive, covering multiple convoy routes, and she often operated unescorted or with minimal protection, reflecting her robust design. Post-war, she returned to civilian service in 1948, resuming her role on the South American route with notable speed and reliability, and later transitioned to full-time cruising by 1960. Her refits included installing stabilizers, air conditioning, and luxury amenities. In her later years, she was repainted white for cruising and hosted notable guests, including royalty and celebrities. After nearly three decades of service, she was retired in 1971, having traveled approximately 2,770,000 miles, participated in 285 voyages, and called at 174 ports, marking her as a significant vessel in maritime history. She was scrapped in Ghent later that year.
