Rear-Admiral Sir Arthur Rullion Rattray, KBE, CB, CIE (2 May 1891 – 10 August 1966) was a British naval officer who served in the Royal Indian Marine and was an air observer during World War I.

[2] He then trained at HMS Ganges, near Ipswich,[1] before serving in the Merchant Service, working for the Aberdeen-based shipping company of George Milne & Co.,[3] until joining the Royal Indian Marine (RIM) in 1912.

[4] Rattray continued to serve in the RIM after the outbreak of World War I, but on 15 February 1917 he was appointed a temporary lieutenant on the General List[5] as a flying officer (observer),[6] with seniority from 7 November 1916,[7] but without prior pay or allowances.

Service records state that he transferred back to the Royal Navy undertaking minesweeping duties at Ramsgate, in January 1918.
