First contract with a South America meat company. Insulated chambers were built into South American service mail ships, which commenced the carriage of meat from the River Plate.

A General Meeting saw the election of two new directors. One was Owen Philipps (later Lord Kylsant). In March he was elected chairman, on his 40th birthday. This commenced the most momentous period in the Company's history.

Maiden voyage of Aragon (I) began. She was the Company's first true 'ocean liner', and at 9,588 tons was some 60% larger than anything RMSP had ever owned. Over the following decade eight more 'A' ships were built, each a little larger than the one before. By now, South America had overtaken the West Indies as the Company's major sphere of operation.



The first significant purchase of an interest in another company saw a portion of the Shire Line and its Far East services acquired. The company was later purchased outright - the first of many.



Caribbean cruising was enhanced with the building of Berbice (I), a particularly fine intercolonial steamer which was effectively a miniature version of the 'A' class mail liners.



A decade which saw great expansion, especially through the purchase of other companies or major interests in them. They included:
- Pacific Steam Navigation Co
- Union-Castle
- Elder Dempster & Co
- H & W Nelson
- Moss Line
- Lamport and Holt
- MacAndrews
- and several coastal lines.
In 1912 Royal Mail's first full-time cruise liner entered service - the first Arcadian (I).
The final ship in the original 'A' ship series, Almanzora, was completed in 1915. She was about 15,500 gross tons.
The group was now massive, and during World War I RMSP's combined losses exceeded 100 group ships.
In 1916 one of the great actions of the war took place between the armed merchant cruiser Alcantara (I) and the German raider Greif. Both vessels were sunk during the encounter.



Two large new mail liners were ordered - Asturias (II) and Alcantara (II). At about 22,000 tons they were the largest in the fleet so far, and for a time were the largest diesel-powered ships in the world. Their first class public rooms were among the finest ever seen aboard ship.



As part of Kylsant's desire to reflect the growing stature of the company, he had approved the construction of a new, large head office in Leadenhall Street, London. It was occupied during 1928.
