The Argentine Navy ( Armada Republica Argentina, ARA ) aviation branch, COAN, was officially established on October 17, 1919 although a navy officer Teniente Melchor Escola graduated as a pilot in 1912.

The Naval Aviation received their first helicopters in 1949: Bell 47 were bought by then president Juan Domingo Peron and different models performed a long and distinguished career which include operations from two aircraft carriers: ARA Independencia and ARA 25 de Mayo

Besides embarking on the fleet ships and supporting the naval infantry, they are also involved in search and rescue missions along the Patagonian coast.
